One hundred and seventy seventh chapter joy and sorrow
Finally, blow air into the iron ladle, not to increase the temperature. The furnace temperature of coke burning is not low, and the white iron that comes out is already very close to pig iron of high carbon steel.
There are just a little more impurities and carbon content. The final oxidation reaction in the iron ladle removes a little bit of phosphorus, silicon, manganese, and carbon, and the steel is released.
By eliminating the need for frying iron and forging, the efficiency will be greatly increased and the output will also be greatly increased.
A steel-making blast furnace can produce 1,500 kilograms of steel per furnace and can be opened once a day. There are four such blast furnaces in Youzhou, which can produce more than two million kilograms of steel a year. This is a lot of quantity. In the late Eastern Han Dynasty, the whole country
If he could only produce five million kilograms of steel a year and build a few blast furnaces, he could surpass the entire Eastern Han Dynasty.
Unfortunately, the mining speed of iron ore and the crushing speed of materials limit the production capacity of the blast furnace, so blind expansion is not advisable.
There are only a few mines.
Prospectors need to work hard. He has sent out many prospecting teams. In the mountainous area in the north of Yuyang County and the Jundu Mountain area, there is copper, gold, silver, and coal. There is coal and iron around Tuyin, Haiyang, Lingzhi, and Xuwu.
But he couldn't find the mineral veins. He only knew that there were mineral deposits in this area and didn't know the specific location at all.
To have a treasure mountain in vain but not be able to enter it is to scratch one's heart and scratch one's liver.
The blast furnace is inspecting the furnace, and another fried iron furnace is about to be renovated. The drawings and preparation procedures have been sent to Yuyang County and Zhuo County. The blast furnaces there will also be converted into steel-making furnaces. The output of steel will be higher and higher. To build a strategic
Tool workshops can increase production capacity.
Just having a steel ingot is not enough, you have to craft it to be useful.
Liu Xiang walked around the armor, sword, and spear and halberd workshops to show off his presence.
Most of the weapon workshops used the steel clamping method to build the work. This is what the craftsmen of the Han Dynasty used to do in the assembly line. They took a few finished products for inspection and found that the quality was good. There was no evidence of substandard goods being passed off as good ones.
The inscriptions on each weapon record the craftsmen of each process. If there is a problem, they can be directly blamed. The punishment will be severe, and they will even be punished. As long as the work officer does not have problems, the craftsmen will not dare to mess around.
The armor and stomach workshop has the largest number of people. It cold-forges fish scale armor, iron-clad armor, and leather armor. There are many processes, which consume a lot of manpower.
Thousands of craftsmen are busy, but the output is not high.
There is no way. There are more than 2,000 nail pieces in a set. The forging craftsman made the nail pieces, passed the inspection once, and sent the qualified ones to the lacquer craftsman. He painted them five or six times, inspected them again, and sent the qualified ones to the lacquer craftsman.
The skillful craftsmen put together the armor in series, and finally the armor has to be cut with swords and tested with bows and crossbows. Only after passing these two inspection procedures will it be recorded and stored in the treasury.
I can’t do many sets in a month.
Cold forging armor takes more time, and now four sets can be produced a month.
Armor stomach is really time-consuming and laborious. The manpower, material resources and time consumed by a set of iron armor are enough for the weapons workshop to make a bunch of swords, spears and halberds.
It is too difficult to improve the nail penetration rate.
The Anping Army has less than 8,000 iron armor and just over 1,000 leather armor. There are also more than 3,000 people wearing the inferior whole-skin leather armor of the Hu people. These are all the armors. There are quite a few cast-iron helmets.
It is popularized throughout the army. It can be made quickly and can be poured with molds. Now that steel has been produced in large quantities, steel helmets must gradually replace iron helmets.
The last place we went to was the crossbow workshop. The ancients were very particular about making crossbows. They made wood in winter, horns in spring, tendons in summer, and combined them in autumn. There are also two years in the north and three years in the south.
In fact, it's not that mysterious, and it won't take two or three years to produce a batch of crossbows.
Logging is done in winter because the moisture is low. It takes two years in the north and three years in the humid south.
Cutting the horns of cattle in spring is because the ancients believed that the blood of cattle is strong in spring and the horns are better.
In summer, the sun is blazing and tendons are more likely to dry out.
The term "Qiuhehe" is caused by the sense of ritual. There are things to do in the other three seasons, so autumn cannot be left behind. Let's just start the combination in autumn.
Most of them are feudal wasteland. Believe it or not, the raw materials are shipped in batches and they can be made at any time.
In Liu Xiang's plan for military combat equipment, bows and crossbows are the most important thing to him. The possession rate of long-range weapons must reach at least 70%. Unfortunately, there is a serious shortage of crossbows, and now they can only be replaced by shuttles.
All the cavalry under his command have been equipped with horned bows. The gap lies with the infantry. The infantry of the Anping army already has 8,000 crossbows, and at least 8,000 are missing. They have 7,000 bows, and at least 15,000 are still missing.
It takes an average of two months for the crossbow workshop to produce a batch of finished products. There are two hundred crossbows and three hundred bows. The technical requirements for crossbow craftsmen are relatively high and difficult to obtain. He has insufficient craftsmen.
It seems that we still have to rely on seizure.
In the crossbow workshop, he also saw a good thing, the fire wall, which should be said to be a combination of the fire wall and the fire kang.
Open flames are not allowed in the crossbow workshop, which can easily cause fires. There was a chief Cao named Zhang You who made a wide step with adobe along the wall, one foot long and more than four feet high. The kang is not a kang, and the wall is not a wall.
The building has a flue planned inside, with an outdoor stove on one side and a chimney leading to the roof along the wall.
He called this a warm table, which was used by the craftsmen in the workshop to keep warm.
It was a good idea. Liu Xiang had really forgotten how to use the fire bed and the fire wall to keep warm. When he saw this, he remembered it.
He told Zhang You his thoughts. As long as there are no problems with the planning of the flue, fire walls and fire pits can be built from adobe or red bricks, and are jointed with clay. They are a good way to keep warm in winter, much better than fire pits and charcoal pots.
Already.
Just pay attention to the chimney. Nowadays, common people rarely use tiles on their roofs, but mostly thatch. The chimney must be built higher and at the downwind. It is best to make some shields, otherwise it will easily ignite the roof. Thinking about this, he was a little hesitant.
Should it be promoted?
After talking about his worries, Liu Xiang asked: "Chang Zhang, do you think it should be promoted?"
Zhang You scratched his head and replied carefully: "If the flue is longer, it shouldn't cause a fire, right?"
"Draw a few more drawings, and first promote it in various workshops and county offices to let them pay more attention and see the effect." Liu Xiang decided to promote it, but he had to pilot it first.
If a fire breaks out in these places, there will be specialized personnel to take care of it, so there won't be any big problems. Even if there is a loss, Liu Xiang can bear it.
The common people are helpless and have water running out of their homes. They cannot bear this kind of loss, fearing that people will die.
With the large-scale promotion of fire pits and fire walls, the demand for fuel will inevitably increase greatly, which is exactly the time to promote coal.
The best coal from the coal mines is used to make coke, and the inferior coal is sent to various furnaces as fuel, but there is still a lot of inferior crushed coal that is useless. It is dirty even if it is thrown into the coal factory to pave roads. This is
waste.
Those crushed coal can be ground and added with clay and lime to make briquettes. The fuel is a big and profitable market.
It is very convenient to burn briquettes for heating, but it requires a special stove.
Liu Xiang was reluctant to use iron materials to make the stove. He decided to use pottery. There was nothing wrong with it except that it was heavier and easier to break.
You can use pottery to make the grate and hearth, and use adobe or masonry to build the main body around it. Wouldn't this solve the problem?
I just started working, I drew the mold for making briquettes and the drawings of the furnace, and hired craftsmen to make them on the spot.
Liu Xiang decided that after Xiaoling River Fish, he liked honeycomb briquettes again, and those rich people would also like it.
