The boiling red molten iron is transported from the blast furnace workshop to the pouring station attached to the converter workshop by a molten iron tanker. Then it is poured into the mixing furnace by a molten iron mixing crane. After pretreatment, the molten iron is then sent in by a molten iron tanker along the trestle.
On the working platform of the converter workshop, the molten iron is fed into the converter with the help of a molten iron crane.
After the converter starts blowing pure oxygen, the slag-making materials are continuously fed into the converter to absorb sulfur and phosphorus in the molten iron.
At this time, the molten iron and slag began to oscillate under the effect of external electromagnetic induction. The boiling molten metal fully contacted with the oxygen blown from the top, and the carbon was continuously oxidized. The carbon content in the molten metal decreased rapidly, and a large amount of carbon monoxide was released.
When the gas is discharged from the furnace mouth, it meets the surrounding air, oxidizes and burns, forming a huge flame.
The steelmaking master wore a canvas long-sleeved protective suit, dark goggles on his eyes, a safety helmet on his head, asbestos gloves on his hands, and thick stockings on his feet. He was holding a huge steel rod and stood in the converter.
On the high platform on one side, among the sparks shooting all over the sky, he calmly observed the situation of the molten metal and the furnace mouth.
After professional training, workers can now judge the temperature of the molten pool and the amount of carbon monoxide emitted per unit time through the color, brightness, shape and length of the flame at the converter mouth.
Generally speaking, in the early stage of blowing, the carbon is less oxidized, the molten pool temperature is lower, the flame at the furnace mouth is short, and the color is dark red. In the middle stage of blowing, the carbon begins to oxidize violently, generating large amounts of carbon monoxide, the flame is white and bright, and the length increases, making it appear extremely powerful.
.When the carbon content is further reduced to about 0.2%, the decarburization speed slows down significantly and the carbon monoxide gas decreases significantly. The flame begins to shrink sharply, becomes soft, shakes, and looks extremely thin.
An Yi stood in the workshop director's room and saw the entire oxidation and decarburization work process through the thick glass window. The steelmaking master performed slag removal on the molten steel, and then the molten steel was introduced into the refining furnace for argon blowing.
Wire feeding, pre-alloying, silicon addition, end point control and other processing, and finally the molten steel is sent into the ingot mold or continuous casting machine through the molten steel ladle to obtain the steel ingot or continuous casting billet.
Wei Yisong, director of Luzhou Iron and Steel Plant, pointed to the three 130-ton converters in the workshop and said proudly:
“Before the pure oxygen top-blown converter steelmaking method was adopted, an open-hearth furnace with a furnace capacity of 600 tons had an annual production capacity of 500,000 tons of steel, and an open-hearth furnace with a capacity of 900 tons had an annual production capacity of only 700,000 tons of steel. However,
, the 130-ton converter we currently use, when the smelting cycle is 30 minutes and operates continuously, the annual production capacity has reached about 2.2 million tons of steel.
"Originally, this workshop only had one open-hearth furnace with a capacity of 900 tons, which took up space and a lot of workers. However, after technical transformation, we dismantled the open-hearth furnace and built three converters with a capacity of 130 tons. The annual steel production capacity suddenly exceeded
to 4.5 million tons. If the shortage of pig iron supply were not considered, if a workshop composed of three 300-ton converters was used, the annual steel production capacity could reach 9 million tons."
An Yi looked at the continuous spray of steel in the workshop outside. Due to the transpiration of the air waves, even the air seemed to be distorted. At this time, another converter began to pour molten steel again. An Yi saw the faces of the workers who endured the high temperature and smoke.
He smiled happily and felt happy in his heart. When he heard Wei Yisong's explanation, he turned around and asked with some surprise: "Why did you improve so quickly all of a sudden?"
Wei Yisong said with emotion: "It's incredible! The new steelmaking method has reduced the cost of steelmaking by 60%, tripled the production speed, and increased the utilization rate of ore raw materials by 80%. It is not surprising at all to achieve the results I mentioned. This is because we have fully
Considering that the converter may malfunction, only
To ensure the continuous operation of two converters. At present, the normal furnace age of a furnace service is about 600 furnaces. Once this number is reached, we must consider replacement. Therefore, when a standard workshop has three converters, keep two converters.
Continuous operation is extremely scientific and reasonable."
Jing Shanpu, deputy general manager of Sichuan South Group who accompanied An Yi on his inspection visit, introduced to An Yi:
"This steelmaking workshop is amazing. In addition to the three converters, it also includes a mixing furnace section, a demoulding section, a whole mold section, a raw material section, a steel ingot mold yard, a slag yard, a raw material yard, and a tar dolomite production line.
Maintenance workshop pump station, scrap steel processing workshop, maintenance workshop, etc. These sections and workshops are only part of the steelmaking plant, with 13,900 tons of installed process equipment, including 5,200 tons of transportation equipment. In terms of technical strength and production capacity, we
It is already the well-deserved number one in the world.”
Jingshan Pu, a native of Huai'an, Jiangsu Province, entered Nankai Middle School in Tianjin in 1918 when he was only fifteen years old. In 1920, he studied in the United States and entered Harvard Business School. He returned to China in 1925 and once set up his own yarn mill and textile factory in his hometown.
However, due to the warlord's exploitation and the impact of Japanese goods, the factory closed down in the second half of 1926. Jingshan Pu went bankrupt and fell ill.
After wasting two years in his hometown, the Northern Expedition was successful. The impoverished Jing Shanpu saw that Anyi Group was recruiting people to study in the United States, so he signed up and went to study in the United States again. This time he was admitted to the Business School of Stanford University. During his studies
, coincident with the outbreak of the U.S. economic crisis, Jingshan Pu joined Zhang Xi’s economic team and participated in
Involved in the acquisition and reorganization of a series of factories and enterprises, after graduating with a master's degree in business administration in 2034, he returned to China and was appointed deputy manager of the Investment Management Department of Sichuan South Group. In 2036, he presided over the investment management department. He was just appointed this year.
Promoted to deputy general manager of the group, Ou Chuer handled group affairs on his behalf during her pregnancy.
Although An Yi had expected that with the upgrade of technology, steel production in southern Sichuan would develop by leaps and bounds, he never expected that the production capacity had reached such a terrifying figure.
Due to the impact of the economic crisis, in the first half of this year, when the operating rate of steel plants was less than 50%, the steel production in the United States was only 20 million tons and the pig iron production was 18 million tons. However, with the outbreak of war in Europe
, presumably the output will quickly double.
Looking at Nanhua, according to Wei Yisong, if the iron ore can be effectively guaranteed, the Taiyuan Iron and Steel Plant using a 300-ton converter production workshop can achieve an annual steel output of 9 million tons. Together with the steel plants in southern Sichuan and southern Yunnan,
An Yiji
The group's steel output can reach 30 million tons of steel, surpassing Japan's 7 million tons, the United Kingdom's 13.18 million tons, the Soviet Union's 18.31 million tons, and Germany's 21.54 million tons, becoming the world's second largest steel producer.
Of course, these are only theoretical figures. As technology and technology improve, it does not mean that the output is really that high. Currently, the supply of iron ore and pig iron is still a serious constraint on Anyi Group's steel production.
Anyi Group is not like the United States. The United States has a unique advantage and can integrate the iron ore resources of the entire American continent for its own use. However, there are only a few iron ore mines in southern China. Although Panzhihua iron ore reserves are rich, they must be fully developed and utilized.
It cannot be achieved in two or three years, so even if Daye is concentrated,
The iron ore resources in Ma'anshan and other places, and the steel production in the southwest region are up to six to seven million tons. As for Nanhua, although the Taiyuan area is extremely rich in coal and iron resources, mining is a big problem, and it is far from being able to do whatever you want at the moment.
By expanding the land, we can fully calculate the output, which is an output of 15 million.
Of course, this figure does not take into account the steel production in Central Asia. At present, the steel production in Central Asia is about two million tons. If the Kemirovo-Temirtau region is included in the calculation, it can increase to
More than 3.5 million tons. In addition, the
For steel production in Central Asia, the pure oxygen top-blown converter steelmaking method must be introduced. In this way, it is entirely possible to increase the steel production in Central Asia to 10 million tons within two or three years. Taken together, the new
Nanhua, with its advanced steelmaking technology, has unlimited development potential.
An Yi asked: "Apart from Taiyuan Steel Plant and Luzhou Steel Plant, are there any other steel plants undergoing technological transformation?"
Jing Shanpu replied: “After the Marco Polo Bridge Incident last year, we merged and reorganized the chaotic steel companies. After giving certain financial compensation, we stripped foreign capital out of the steel companies. Now we have formed a large steel group in the region.
pattern.
"Since Xufu often has domestic and foreign guests visiting, the group rejected the application for technical transformation of the Xufu Steel Plant. It still uses an open-hearth furnace with a capacity of 900 tons. It has a total of three large-scale production workshops with an annual steel output of 150
Thousands of tons. In addition
Steel plants in Ziliujing, Zhaotong, Xuyong and other places, limited by scale, each have a 600-ton open-hearth workshop, with an annual steel output of about 30,000 to 400,000 tons. We are currently transforming the Ning'er Steel Plant in Simao, southern Yunnan.
, the scale is similar to that of Luzhou Iron and Steel Plant.
"The technical experts from the former Xufu Iron and Steel Plant who developed the new steelmaking method have all been transferred to the Taiyuan Iron and Steel Plant in Nanhua to continue to engage in related research."
An Yi nodded happily, and then joked in Sichuan dialect: "It's amazing. With so much steel coming out, we may not be able to use up all our planes, cannons and warships. How about making a fortune now?"
A burst of hearty laughter suddenly came from the room.
After leaving the steel plant, Jingshan Pu accompanied An Yi and then visited other factories and enterprises in Luzhou Jiangbei Industrial Zone.
The entire Luzhou Jiangbei Industrial Zone, built in Longmatan on the north bank of the Tuojiang River in Luzhou, covers an area of about 1,000 square kilometers. The production plant area accounts for about 40% of the total land, including heavy industries such as steel, metallurgy, machinery, military industry, tractors, and automobiles.
It occupies the majority, and in addition there are supporting maintenance and auxiliary machine repair, tool factories and other enterprises.
The second land use project is storage land, which accounts for almost 20% of the total land use, including various warehouses for raw materials, equipment, finished products, semi-finished products, etc., arranged in rows.
The third largest land use is mainly power and municipal facilities in industrial zones, such as oxygen plants, thermal power plants, air compressor stations, oil depots, water plants, sewage treatment plants and various engineering pipelines, etc., and the use of industrial "three wastes" to solve production needs
, leftover materials and related factories that provide supporting processing for large manufacturers.
The remaining land is mainly for public services, including residential areas, office areas, hospitals, canteens, bathrooms, barber shops, kindergartens, schools and parking lots, etc.
In order to meet the needs of the industrial zone, the industrial zone has built special railway lines. Highways and railways are directly connected to the shipping terminal. In addition, there are pipelines for transporting fuel and ropeways for lifting goods. With the outbreak of the war, the entire industrial zone
It was officially established as a military unit, and a regiment was stationed for protection. Especially after the pure oxygen top-blown converter steelmaking method was discovered, the steel plant became a first-class confidential unit, and the garrison force increased to two regiments, one of which was mainly responsible for steel.
Factory security work.
After visiting the entire industrial zone and returning to Luzhou city via Tuojiang Bridge, it was already four o'clock in the afternoon.
Major General Xu Yichen, director of the Nanhua Branch of the Fourth Department, waited in the Luzhou City Hall Building for about half an hour. When he saw An Yi, he immediately stepped forward to salute and delivered an urgent report from Nanjing.
An Yi returned to Xufu from Nanjing three days ago, and immediately sent a special negotiation team, led by Zhou Chongan, to rush to Nanjing to start negotiations with the Nanjing National Government represented by Kong Xiangxi and Song Ziwen.
Chiang Kai-shek was extremely angry at An Yi's departure without saying goodbye. He was sensitively aware that An Yi might have noticed his intention to suppress him, but for a while he was helpless. During the negotiations, the central government always insisted on the bottom line and was not willing to give in even a step.
, the negotiations reached a deadlock for a while.
In the following days, the central media was in trouble.
"Central Daily News" and radio stations controlled by the Nanjing government have broadcast "letters from the masses", lashing out that since the Anyi Group has occupied South China, Siam and Central Asia, it should take the overall situation into consideration and voluntarily abandon Syria and southern Yunnan. Now it is not only long-term
They refused to take the stolen power, passively avoided the war, and did not think about serving the country. They still supported their own troops and carried out separatist rule. Someone called on the "Central Daily News" to "all the people of the country, unite to attack." For a while, public opinions abounded.
The Anyi Group was naturally unwilling to be humiliated and sternly rebuked the influential Syrian government radio station, saying that since the Anti-Japanese War, the Anjia Army had been on the front line of the Anti-Japanese War. Since the July 7th Incident, the Chinese *** team had achieved a series of achievements.
Great victory, all for the Anjia Army
How can we say that the Anjia Army is not patriotic? In addition, now that the Anjia Army has contained the main force of the Japanese army in Siberia, the 30th Group Army under the Anjia Army is also the mainstay of the North China War of Resistance. With all this, how can we say that the Anjia Army is not patriotic?
Passive to avoid fighting?
Furthermore, the southwest is originally a barren land. Without the long-term investment of Anyi Group, how could we have achieved today's construction achievements? In terms of infrastructure, Jiangnan and Jiangbei far exceed the southwest, but why is there so much in the south of the Yangtze River except for the old people who laid a solid foundation for Anyi Group?
Nanchang Industrial Center and other places have excellent industrial development. Doesn’t this mean something?
Subsequently, newspapers such as "Shen Shen", "Ta Kung Pao", "Republic of China Daily", "Yi Shi Bao", "Oriental News", "Zi Lin Xi Bao" and magazines such as "Oriental Outlook Weekly" and "Liangyou" suddenly became full of articles.
Nan Hua’s enrollment advertisement appears on the paper:
Nanhua will recruit young people (regardless of gender) from six to 22 years old across the country. Not only will Nanhua provide free tuition and miscellaneous fees, but they will also be responsible for transporting them to Nanhua to study. They will also provide free clothing and three meals. After graduating from high school, you can choose to study in Nanhua.
Employment in Nanhua. If you are admitted to a university in Nanhua, not only will your food, accommodation and clothing continue to be free, you can also apply for a student loan, which will be deducted from your salary after you work.
For this recruitment, the Nanhua government, Jiangnan Group offices across the country and the distribution points of "Oriental News" can all register. After the gentry from all over the country obtain enrollment qualifications, they can help Nanhua Group recruit students. For each person recruited, two will be paid.
Yuan Yin Yang’s reward.
Anyi Group's enrollment announcement caused an uproar in the country.
So far, the National Government has not completely solved the problem of compulsory education. From the 18th to the 25th of the Republic of China, except for the areas controlled by Anyi Group and its allies (compulsory education was basically universal in this area), the ratio of college students in China was 1:16,000.
, the ratio of middle school students is 1:4407, and the ratio of primary school students is 1:60. Only a few people can enjoy education. This time, Nanhua recruits students with great fanfare, and there will be an extremely bright future after graduation. Who is not excited?
Are you excited?
Of course, some people suspect that this is disguised human trafficking and recruitment of child labor. However, Anyi Group stated that parents of those who have children studying in Nanhua can follow them to Nanhua. Those who do not have living expenses can choose to work in factories and enterprises in Nanhua. This is the case.
As soon as the generous treatment was announced, it immediately triggered a huge application frenzy, and the public opinion offensive launched by the National Government suddenly disappeared.
Seeing Xu Yichen's solemn expression, An Yi took the telegram and read it carefully, with icy eyes: "There is no need to worry about this matter. Now our own expanded production line cannot meet it, let alone supply the demand of the domestic market. After so many years
, we have always been resigned to the situation, but this time we have to be tough no matter what. I don’t understand where the central government has the confidence to confront us..."
Xu Yichen said: "I came here specifically for this. Director Zhao heard an unconfirmed news that the Party Headquarters issued an order to local governments, requiring the closure of our offices in various places, and at the same time, requiring the garrisons in various places to set up checkpoints.
, ban our trade routes.”
An Yi suddenly changed his color and said angrily: "How dare you, rat! Later I will electrify the whole country in my name and ask local governments and garrisons to ensure legal transportation and operations. Normal trade circulation can promote economic development. Closed small farmers
The economy will only make our
The product has lost its competitiveness in the world. If anyone dares to break the rules, I will let him know the consequences of breaking the rules. The fourth hall must also prepare urgently to say hello to those arrogant soldiers and keep a line in life. In the future
It’s nice to meet each other, but if you insist on going your own way, don’t say you didn’t predict what you said!”
It was the first time that Du Yi saw An Yi getting so angry. His heart trembled. He nodded solemnly and turned to leave.
An Yi asked Shen Feng again: "Are there any battle reports from Western Siberia?"
Shen Fengdao replied: "Li Jinlong's Corps is still confronting the Japanese army on the Parabinsk front line. The Japanese army in Parabinsk City and the Japanese army in Kuibyshev City in the north are horns of each other and support each other. Moreover, the Japanese army is more ruthless this time, digging.
The anti-tank trench is six meters deep and twenty meters wide
, there are machine gun positions, minefields and knife arrays set up at the bottom of the anti-tank trenches, which our engineers cannot blast. At the same time, due to heavy rain and fog in Siberia in the past two days, our air force cannot dispatch, and there is no way for the time being.
Break through the enemy's deep positions."
An Yi nodded: "Japan is not a soft persimmon in the first place. Their reaction is reasonable. Now it depends on the speed of Xiao Wu, Hu Jiyang and Yang Jiuxiao's troops! If they can suddenly appear on the enemy's back, the Japanese army will surely The situation is in chaos."
Shen Fengdao changed the topic and asked: "Are you staying in Luzhou or Huixu Mansion tonight?"
An Yi looked at the setting sun in the west and waved his hand: "Go back to Xiyuan and have a good rest at night. Tomorrow we will return to Xinjing and visit the counties and cities around Xinjing to see the popularity of compulsory education. , and then go to the newly built industrial zones in various places to check the construction status of Boy Scout schools, middle schools and universities. This time we can speak big words. We don’t want too many people to pour in and we will not be able to satisfy us, which will be a big loss. Got it!"
Shen Fengdao said with a smile: "It's not a big problem. Our talent plan started in 2007 and has been implemented for 12 years now. During this period, more than 50,000 people have returned from school. Compulsory education has been popularized in southern Sichuan. So far, there have been Eight years have passed, and compulsory education has been universalized in southern Yunnan for five years. If we use elites who have returned from overseas studies to teach graduate students and college students, university graduates to teach high school and junior high school students, and teacher college graduates to teach elementary school students, there should be no problem."
