Chapter 302 What should we do in the face of bombing by Japanese aircraft?
?
"Bah bang bang!" Immediately afterwards, all department heads applauded and congratulated the birth of the most advanced high-tech group.
There was endless applause, and Professor Zhuang and others were fine. After all, they had expected it. However, Zhao Zhangcheng, who had just arrived from Liushugou Arsenal, looked confused.
What's going on?
How can I, a rough guy like me, join this top science and technology group that seems to be awesome?
Zhao Zhangcheng looked at Chen Kang with confusion on his face, confusion and desire in his eyes.
He wanted to know why...
Feeling Zhao Zhangcheng's gaze, Chen Kang smiled and did not give any explanation. After everyone's applause fell, he continued: "Next, each department will introduce itself and report on the recent situation."
After finishing his words, he turned his attention to the head of the General Affairs Section sitting on his left.
"Hello, expert from the top technical team. I am Lu Yuan, the chief of the General Affairs Section. I would like to report on the responsibilities and recent status of the General Affairs Section. Currently, the General Affairs Section is responsible for the transportation, road construction, and logistics support of various factories and mines."
General Affairs Section Chief Lu Yuan stood up suddenly and saluted the three people directly opposite him: "As of today, there are 493 registered members of the General Affairs Section. For transportation, there are 5 Dodge trucks and 1 German-made red-head car with a large convertible.
1, a total of 120 horse-drawn carriages, 94 mule carts, and 50 ox-carts, all in transport status, with a daily transport capacity of 100 tons. In terms of highways, a Yushen Highway is under construction, using a gravel roadbed. This is about
Please review all the information in the General Affairs Section."
"Thank you, Comrade Lu." Professor Zhuang stood up and took the documents from Lu Yuan's hand.
"Hello, Professor Zhuang, hello classmate Yu. I am Zhuang Qianding, the chief of the Ordnance Engineering Department. I would like to report on the responsibilities and recent status of the Ordnance Engineering Department. The Ordnance Engineering Department has jurisdiction over the Liushugou Central Arsenal, Nanyaogou Repair Station, and Shuiyangou Repair Station.
, including administrative and technical cadres and workers, a total of 187 people, without an old-fashioned lathe, a vertical deep-hole drilling machine, a vise, and several grenade shell molds."
Bai Huishang, the chief of the Ordnance Industry Section, stood up, raised his hand in salute, and reported on the situation of the Ordnance Industry Section: "Liushugou Arsenal can now produce wooden handle grenades, and the designed daily output has been increased from the original 200 to 600. The actual daily output has been affected by
The supply of gray pig iron is limited to only 30 pieces."
"The Ordnance Industry Department is organizing research on the medium-sized formal rifle project and the 80mm mortar project. It is expected to complete the imitation task of the 80mm mortar within eight months, retreat to the small batch production stage, and complete the imitation of the medium-sized formal rifle within one year.
Production, this is information about the Ordnance Engineering Department that we don’t have, please take a look at it from the lowest science and technology team.”
"Thank you Comrade Hu."
Professor Zhuang thanked him again and took over the extremely important military production materials of the base area.
After Zhuang Qianding sat down, the remaining eight departments of the Military Industry Bureau spoke one after another to report the situation.
"The Public Works Department has jurisdiction over the electric furnace steel plant, sulfuric acid plant, petroleum plant, low furnace iron plant, and coking plant. There are a total of 1,740 workers and technical cadres in each factory. The electric furnace steel plant has a daily output of 240 kilograms of electric furnace steel, and the annual output is about
88 tons, the sulfuric acid plant produces 9.5 tons of sulfuric acid per day, the petroleum plant produces 1.2 tons of oil per day, and refines a total of 500 liters of gasoline and diesel. The low furnace iron plant is under construction to produce a low furnace of 2 tons of molten iron per day, and the coking plant produces eight tons of coke per day.”
"The Gunpowder Department has an explosives factory under its jurisdiction, with a staff of 47 people. It can produce single-base propellants, double-base propellants, and explosives. The daily output has increased from 300 kilograms at the beginning of the factory to 450 kilograms now."
“The Mineral Resources Section has jurisdiction over 17 mines including Shenmu Coal Mine, Shenmu Iron Mine, Yimeng Crystalline Graphite Mine, Jingbian Copper Mine, and Yulin Limestone Mine, which can independently supply iron, copper, coal, oil, natural gas, and limestone.
There are seventy kinds of raw materials including quartz sand, graphite, alkali, Glauber's salt, salt, boron, and phosphorus. The mining volume and related data of each mine are here, please take a look."
Through the brief information given by the seven departments of the Military Industry Bureau, Zhao Zhangcheng and Bai Hui now basically have a grasp of the overall status of the entire wartime production plan.
When the person in charge of the Mineral Resources Section finished speaking, Hu Zhigang, who was sitting at the front, fell into confusion. Looking at everyone, he knew what to do.
Sensing Hu Zhigang's reaction, Yu Hua did not hesitate to announce his withdrawal from the discussion stage of the steel plant site selection. Instead, he signaled for his speech: "Comrade Zhao, please briefly explain the withdrawal status of the 60mm mortar project. This project has been affected by
The headquarters pays little attention to it, after all, artillery is very important to us."
The 60mm mortar project has received little attention from the headquarters. Although the formal rifle is important, the artillery is even more important.
After hearing Yu Hua's explanation, Professor Zhao Zhangcheng and Bai Hui nodded to express their understanding.
"Dear leaders and experts from the lowest science and technology group, the design drawings of the 60mm mortar project have been completed, and workers outside the factory have been organized to process and manufacture the prototype gun. However, we encountered a small problem in the barrel. We have fixed the 60mm mortar with seams.
Steel pipe." Hu Zhigang stood up without saying anything. He recalled his development experience and learning process in the arsenal during this period, sorted out his words a little, and slowly reported on the current status of the project.
After saying that, he immediately sat down.
Nowadays, with the help of artillery experience provided by Hu Zhigang, the Liushugou Arsenal 60mm mortar project has completed all designs and retreated into the actual manufacturing process. However, how to manufacture seamed steel pipes has become a stumbling block for the arsenal technicians and engineers.
The smallest problem faced by workers.
How to make a gun barrel with an inner diameter of 60 mm?
After hearing this, Zhao Zhangcheng pondered for a while, turned to look at Lu Yuan, and said: "Regarding this issue, before the meeting started, Lu Yuan and I went to the arsenal to find out whether it is difficult to manufacture medium-diameter seamed steel pipes.
It is difficult and difficult.”
There are two ways to manufacture mortar tubes. One is the rolling seam steel tube process, and the other is the barrel blank boring process. Considering economic factors, the latter is usually chosen. After all, the barrel blank is bored.
The processing cost is several times less than the latter. Only the barrels of low-bore pressure artillery such as howitzers, tank guns and cannons are processed by boring the barrel blanks.
The rolling process of seamed steel pipe is divided into cold rolling and hot rolling. The mainstream process is cold rolling. China basically has hot rolling process.
Feeling Professor Zhuang's gaze, Lu Yuan understood what he meant and kept this in mind.
"Thank you, Professor Zhuang." When Hu Zhigang heard these words, he was stunned for a moment, then he was overjoyed and thanked him quickly.
Zhao Zhangcheng shook his head: "Thank you."
…
"Okay, now we have concluded the discussion on the location of the decommissioned steel plant. Professor Zhuang, I want to know the recommendations of the minimum science and technology group first. This is the map of the Shaanxi-Gansu-Ningxia base area." After the current status report of the 80mm mortar project is completed,
Yu Hua announced that he would withdraw from the main topic of today's meeting, then took out a map and placed it on the table, looked at Professor Zhuang and asked.
The heads of various departments in the conference room cheered up and turned their attention to the lowest technology group directly opposite.
"The location of the steel plant specifically requires that it be as close as possible to the raw material supply area, with convenient transportation and rugged terrain. Taking into account the factors of war, it should be a place that is easy to defend and difficult to attack. After discussions between Lu Yuan and I, there are no eight initially determined places.
, Yulin, Jingbian, Mizhi." Zhao Zhangcheng and Lu Yuan looked at each other, then looked up at the map of the border area behind them, pointing their fingers to eight identical places.
Yu Hua was thoughtful and said respectfully: "Professor Zhuang, can you explain it in detail?"
Bai Huishang heard this and turned his eyes to Lu Yuan.
"Director Chen, dear comrades, Jingbian is located in the northwest of Yancheng, bordering the Ikezhao League, backed by Hengshan Mountain, rich in water resources, and there is no Jingbian copper mine. It is only 200 kilometers away from Shenmu, a raw material supplier. Whether it is
It is very convenient to build roads or build railways in the future."
Lu Yuan stood up and hurriedly gave the reasons and advantages and disadvantages of choosing Jingbian: "Militaryally, if the Japanese army wants to retreat and attack Jingbian, they can either choose to cross the Yellow River from northwest Shanxi, cross Luliang and Hengshan, or go from Suiyuan to Baotou
Cross the Yellow River and then attack Zhaomeng and Yulin."
After hearing Lu Yuan's analysis, everyone present nodded. Chen Kang and Yu Hua, the heads of the general affairs department who were former combat staff officers, expressed their affirmative attitude.
Shaanxi is located in the Loess Lowland, with simple terrain, crisscrossing mountains, and extremely convenient transportation. The difficulty for the Japanese army to retreat from the base in northern Shaanxi was less than ten times that of the plains.
"Compared with Jingbian, Yulin is closer to Yikezhao League, backed by Hengshan Mountain, rich in water resources and mineral resources, about 80 kilometers away from Shenmu, and geographically located in the middle of eight places. The supply of various industrial raw materials is very convenient, and it is closely related to raw materials.
The road and railway construction conditions in the supply area are excellent, and the military situation is similar to that in Jingbian, relying on Luliang and Hengshan Mountain as natural barriers, but due to its proximity to the Ikezhao League, the risk is slightly higher than that in Jingbian."
Lu Yuan continued, pointing to Yulin with his left hand: "In fact, from an industrial perspective, Yulin is the most suitable place for industrial development among the eight locations. In the future, the Yuyi Industrial Zone can be established based on the Yike Zhao League."
Yulin's development potential is extremely profound. It has the Jingbian copper mine on the right, the Shenmu coal and iron mine on the left, self-produced limestone, quartz sand and other minerals, and the super raw material base of Yike Zhaomeng in the north, which can accommodate 7 million tons of steel.
Industrial area with annual output.
After hearing the reasons, advantages and disadvantages given by Lu Yuan, everyone turned their eyes to Yulin, thinking that this seemingly ordinary place had so few advantages.
"Where's Mizhi?" Yu Hua asked.
Lu Yuan said: "The advantage of Mizhi is that it is located in a hill, with the best risk, close to Shenmu and Yulin, rich in water resources and natural gas resources. The disadvantage is that the place is large, the development potential is sufficient, and it can barely accommodate
Steel plants, and the construction of road and railway transportation is easy. I have finished my speech, thank you Xiaojia."
Mizhi is surrounded by the Hengshan Mountains and is close to the Ding River. It is rich in water resources and mineral resources. However, the area of the place is small. It can barely accommodate a 35,000-ton steel plant. It is basically possible to expand it recently.
As Bai Hui dragged out the reasons, advantages and disadvantages of the selection of the eight places, the conference room fell into silence, and everyone present except Professor Zhuang was lost in thinking.
Jingbian...
Yulin...
Rice fat...
"Deputy Team Leader Yu, I don't have a question." At this moment, Bai Hui, the head of the General Affairs Section, suddenly raised his hand and issued a message.
Lu Yuan responded: "Chief Lu, please speak."
"What should we do in the face of bombing by Japanese aircraft?"
