Chapter Seventy-One: Blast Furnace Ironmaking

Lu Bu, Chen Gong and others returned to Jinan County, after all, that is where the foundation lies.

Gao Shun adjusted quickly, and a thousand trapped camps were still trapped in the camp, still elite cavalry, and only two changes were made, one was to learn to swim, and the other was to learn to sit in a boat.

These two seemingly simple requirements actually come at a great cost.

The sailors recruited by the 3,000 seashores are relatively worry-free, and they are used to seeing the sea, and Weishan Lake is a water blister.

There are only dozens of fishing boats sent by Lu Qian, which are used by local fishermen to raise their families for fishing, and this kind of boat is made of penny, not to mention the speed, and there are few people, that is, it is used to patrol around the water village.

Gao Shun discussed things with the carpenter and several members of the navy.

"There are timber, there are a hundred and ten craftsmen, and we sailors can do small work. The owner didn't say what type of ship to make, but only said that it was required to be fast, able to load goods, and able to load people. ”

Everyone is talking and has all kinds of ideas.

But the local fishermen among the sailors: "General Gao, our lake is different from other places, it looks quite big, but the water is very shallow, if the draft is deep, it is difficult to move an inch, in the villain's opinion, let's choose a flat-bottomed centipede boat." The captain of the boat is more than ten zhang, equipped with thirty oars, which can carry sixty or seventy people, and when you want to be fast, the sailors take turns rowing, and the boat is as fast as flying. ”

After repeated arguments, Gao Shun decided to build twenty centipede ships as warships, and the sailors fought with giant crossbows and bows and arrows. The main thing is that this kind of warship is easy to build, and it can be built with the existing level of craftsmen. As for the building ships, ships, etc., these craftsmen have no drawings and will not build them at all.

The team's reclamation was also carried out well, and in just half a month, more than 300 acres of land were made out and many seasonal vegetables were planted.

At this moment, Lu Bu is busy in the newly built Limin Iron Works in the south of Jinan County.

It covers an area of dozens of acres and has more than 500 craftsmen.

Three blast furnaces are lined up in the tall factory, five meters high and one and a half meters in diameter.

Zhang Tiezhu, the director of the factory, led the craftsmen to meticulously inspect and measure. Just such a blast furnace was filled with 3,000 catties of iron ore, 1,500 catties of coke, and a large amount of limestone.

Zhang Tiezhu came over and nodded to Lu Bu: "Ready." ”

"Okay, open the furnace immediately after the sacrifice."

"Yes."

Li Su presided over it, and Lu Bu, Zang Ba, and Zhang Tiezhu all participated.

Especially Zang Ba came late, just in time for the sacrifice.

A pig, a sheep, a chicken, and a fish were prepared.

Li Su read the sacrificial text aloud and begged the heavens for protection.

After the sacrifice was completed, Zhang Tiezhu announced the ignition.

The fire was blazing, and the sturdy donkeys pulled the wind raft to provide a steady stream of wind power for the blast furnace.

Zang Ba came to Limin Iron Mine for the first time and looked a little confused.

"My lord, why is this iron furnace so high, and why is there no smoke from the burning coal?"

"This is called a blast furnace, and it can produce more than 1,000 catties of iron at a time."

"How often can that come out?"

"Although this is the first furnace, the furnace has been empty for a day, and soon, at most three or four hours, it will come out with good iron, good material for casting iron pots."

I know a little about ironmaking Zangba, but I'm more curious, isn't it pig iron that casts iron pots? It's not the same crispy.

Accompanied Lu Bu from morning to noon, at most three hours later, he heard someone shouting that the iron was out, the iron was out. ”

Lu Bu and Zang Ba came to the iron furnace together, and saw that the red molten iron had quickly flowed into the iron pool, and at least thousands of catties of iron came out at this time.

On this hot day, the steelmakers sweated profusely and cleaned the slag immediately after the molten iron was released. Then re-feeding, the donkey is too hot to stand, and the huge bellows can only be driven by manpower

Three blast furnaces come out together, and it is 3,000 catties at once, and at least 6,000 catties a day.

The molten iron comes to the die-casting room through the slide, where hundreds of molds have already been prepared, divided into large iron pots, medium iron pots, and small iron pots. According to the size, the craftsmen take different amounts of molten iron and put them into the mold, and then press the other half of the mold on.

This is a very dangerous process, if you are not careful, the molten iron will burn your hands, and the operator wears sheepskin gloves and operates carefully.

Today I am very unskilled, the three pots of molten iron only made 600 large iron pots, 600 medium iron pots, and the rest of the molten iron is cold, so it can only be made into pig iron pieces and sold directly to pig iron shops.

The cast iron pot cooled quickly, but in half an hour, a mouthful of iron pot came out.

Zang Ba couldn't close his mouth in surprise: "This, this, that's it, six or seven hundred cauldrons, such a big pot can be sold for five hundred wen in the countryside." ”

Zang Ba felt a sense of powerlessness, his iron mine in Laiwu was incomparable to Lu Bu's Limin Iron Factory.

"Aren't you afraid that I'll learn the technology? It's not complicated to look at. ”

Xuan Gao laughed, I'm afraid that you won't invite you to come and see it. What's more, this is just smelting pig iron, and the things produced are nothing more than iron castings, and I don't know much about things, just a superficial skin, and technology needs to be developed together. There is more business in the world, what do I Lu Bu want so much money for, isn't it all the people of the world in the end? ”

"The lord's words made Zang Ba ashamed."

Once the cast iron pot is out, it immediately moves on to the next process to remove the burrs, which are sharp, sharp and can hurt people's hands if they are not removed.

The next step is to put on a straw mat and put it together to pack.

The mules of the caravan outside are already waiting to pull the goods, which are the officials and merchants of Qingzhou, and they are transported to all parts of Qingzhou for sale, and the price is slightly cheaper than the market price.

Since Lu Bu took charge of Qingzhou, the price of salt has dropped sharply from 20 wen a catty to 10 wen a catty, which is lower than the original price of private salt. Now the price of all kinds of iron products has also been reduced, which is a great thing for the people.

In order not to reduce tax revenue, what Qingzhou has to do now is to expand domestic demand and foreign trade.

Zang Ba was also very happy, because Lu Bu gave him a big business, that is, coke, and Taishan County was rich in coal resources.

Ironmaking and steelmaking required the processing of coal into coke, so this business was handed over to Taishan County of Zangba.

"Xuangao, we must not relax in military training, the current situation will only become more and more chaotic, and it will definitely not get better. According to the information from Xiliang, Han Sui and Ma Teng have already raised troops from Xiliang to crusade against Li Dao and others and rescue Emperor Xian. Not to mention Cao Cao, now secretly stealing ancient tombs and raising military salaries, I believe it won't be long before Cao Cao will also be a strong army. ”

"Then are we going to expand the army too?"

Lu Bu shook his head: "Now we have infantry, cavalry, sailors, and city defense battalions in various places, and now there are at least 150,000 troops, such a scale, as long as we train to be elite, there is no need to expand in the short term." But we need to train the strong men twice a year to deal with a sudden all-out war. ”
