Siheyuan starts from a good life

"Start feeding."

At Jiang Yan's order, the sintered ore was carried by the members in backpacks or grain bags and put into the furnace along the slope built from the furnace mouth.

"Add coal." Jiang Yan then ordered.

As soon as Jiang Yan finished speaking, people filled the furnace with prepared coking coal and started to light it.

"Mr. Jiang, thank you for your hard work." Seeing Jiang Yan finish his work, Ma Youcai, who was standing there, hurried over.

After listening to Jiang Yan's words, Ma Youcai nodded calmly.

"It has been extinguished, the temperature has dropped, and the kiln can be opened."

Thinking of this, Jiang Yan turned back to the small blast furnace.

"I understand, Mr. Jiang."

Jiang Yan wanted to laugh a little when he heard this. Even if he hadn't said this, the village below him would have provided us with unplanned supplies.

"The technical staff trained by you will fully accept it after opening the kiln. You will only provide guidance on the side. Do you understand?"

A large amount of air is blown into the blast furnace, which on the one hand continues to increase the furnace temperature and on the other hand allows a chemical reaction between the oxygen in the air and the carbon in the molten iron. To complete the decarburization of molten iron!

To put it bluntly, the difference between iron and steel lies in the carbon content. The carbon content is high and the iron produced is brittle, which is pig iron. The carbon content is low and the iron produced is too soft, that is, wrought iron.

When practicing steel, you must first ensure the temperature. Since there are no professional measuring tools, Jiang Yan can only control the temperature inside the furnace by feeling. In order to fear that the temperature will leak, Jiang Yan also specifically asked to use yellow mud with straw added around the furnace. Seal it again.

As the temperature of the furnace continues to rise, the ore in the furnace gradually melts and turns into red molten iron.

"Then open the kiln and pay attention to safety." After Jiang Yan said this, he patted the technician on the shoulder.

The members began to add ground limestone to the molten iron, using limestone powder to absorb impurities in the molten iron.

The purity of this batch of iron ore is not high enough. If the impurities in the molten iron are not removed, qualified steel cannot be produced.

Because the weather was relatively hot, He Yuzhu made most of the meat into bacon.

After observing it, the technician picked up a slightly hot steel block and came to Jiang Yan.

Jiang Yan shouted loudly: "Get ready to start the furnace."

"The fire has gone out, right?" Jiang Yan asked the technician at his research institute there.

What Ma Youcai didn't know was that Xu Damao had been completely liberated since the technical personnel from the research institute came to support him. He took advantage of this gathering to become familiar with almost all the captains, and then relied on With his eloquence and some supplies that were in short supply in rural areas, he soon became the guest of these captains.

They even hired people to build a house with bricks in a nearby mountain valley that specializes in making bacon and bacon. Several people from the institute's back kitchen came to help.

Jiang Yan didn't say anything. He picked up the refined steel block and took a look. The steel block that was supposed to be white was a bit gray in color. When he saw this color, he knew that what the technician said was right. However, even with such relatively low-end steel, The molten iron that was melted with iron tools before was made many times better. That was iron, and this is steel!

"Leader Jiang, this is steel, we succeeded." Ma Youcai doesn't care about the quality of the steel. As long as he can make steel, it will be a huge political achievement.

Taking advantage of my free time, the square in front of these kilns was already filled with pre-made brick cakes.

After the steel ingot cooled down, the technician hurried forward to take a closer look, and even reached out to touch the steel ingot, which was still a little hot.

What Qin Fengshou could see, these captains also saw it. After all, these people were really not stupid, but they didn't point it out.

"Thank you, Leader Jiang, for your selfless help. I didn't say anything before. From now on, all unplanned supplies in our Shili Township will be given to your research institute."

Unknowingly, it has been half a month since I came out, and I have finished what I should do. When He Yuzhu sent the bacon back yesterday, he told himself that all the parts of the trial tricycle have been produced, and the engine mold has also been produced according to the drawings. After coming out, I waited for Jiang Yan to go back and guide the installation of the engine. I only waited for the first batch of steel to be refined before going back to preside over the assembly of the tricycle.

When Ma Youcai said this, he looked at Jiang Yan closely without blinking, for fear that Jiang Yan wouldn't be able to say "no".

Under Ma Youcai's expectant eyes, Jiang Yan nodded heavily.

Then the blowing device continued to blow, and several strong men shouted slogans and pushed the blowing device hard.

There are a lot of prey in the mountains now, and the harvest has been quite good in the past half month. The jeep delivers the harvested supplies back to Sijiu City every day.

With these captains providing cover, Xu Damao even organized some hunters with better skills to hunt in the mountains.

After hearing what Ma Youcai said, Jiang Yan told him the style and standards of the thermometer. Fearing that he would make a mistake, Jiang Yan even drew a drawing for him.

Jiang Yan, who returned to the small blast furnace, said nothing and quietly watched the changes in the small blast furnace.

The sealing bricks at the kiln entrance were removed, and the personnel who had already been arranged began to go inside and take out the fired red bricks.

So much so that Xu Damao used iron pots, farm tools and other materials to collect a lot of meat and mountain delicacies from their captains.

"Kiln opening"

The technician who heard Jiang Yan's words looked embarrassed and said, "Mr. Jiang, there is no special thermometer here. The temperature cannot be controlled so accurately."

The small blast furnace is opened, and the red molten steel is poured out of the small blast furnace and then flows into the mold.

"I'll make the arrangements here. They must be arranged. Mr. Jiang, the first furnace of red bricks will be out soon. I would like to trouble you to go and take a look."

"Xiao Hu, look, this should be because the temperature is too high. The firing temperature of the next batch should be lowered slightly." Jiang Yan took the bricks and said to the technicians at the research institute who were now instructing them in firing.

浜屽叚banduo笁:cbanduo簩锲:cbanzuo浂a:c锲涗竴涓::涓鍏

After firing enough refractory bricks, four of the original five kilns have been converted into kiln mouths dedicated to firing red bricks and green bricks.

"Mr. Jiang, the carbon content in this steel is still relatively large, and the steel mouth is relatively brittle. This steel can only be used to make some agricultural tools and the like. If you want to make other tools, you must go through a second refining process."

Only when the carbon content is appropriate can the steel produced be called steel.

As time goes by, the carbon content in the molten iron becomes less and less, and it begins to transform into steel.

"We are all serving the people. What's the hard work? It's okay. We have manpower arranged here. The fire cannot be stopped. I will also send technical personnel to follow."

Hearing Xiao Hu's words, Jiang Yan nodded.

As a large amount of cold water was poured onto the mold to cool down, the molten steel solidified into pieces of steel ingots that were still sizzling and emitting white smoke.

As the fire grew larger, a large amount of thick smoke began to be emitted from the furnace mouth.

"Okay, I'll send someone to buy it now." Ma Youcai took the drawings and quickly arranged for the members to go to Sijiucheng to buy the drawings.

"What kind of thermometer? I'll send someone to Sijiu City to buy it right away." Before Jiang Yan could speak, Ma Youcai next to him quickly interjected.

"Quickly, send this steel block to the county government to announce the good news." After cheering, Ma Youcai arranged for the members to take the steel blocks to the county to report the good news, but they came directly to Jiang Yan.

Jiang Yan and his technicians kept an eye on the state of the molten iron, and estimated that it was almost done.

Everyone cheered when they heard Ma Youcai's words. The sound was a bit deafening.

As soon as he finished speaking, the green bricks that originally sealed the entrance of the kiln were removed by the members, and the heat wave came out of the kiln. Feeling the heat wave, Jiang Yan took two steps back.

After looking at Jiang Yan's affirmative answer, Ma Youcai held up the still hot steel block and said loudly to everyone in Shili Township: "We have mastered steel, we have mastered steel."

Jiang Yan took out a piece of red brick and tapped it with his hand, which was warm. The brick made a crisp sound like ordinary ceramics. He nodded, looked at the color of the brick again, and found that this batch of bricks Red with black.

When Jiang Yan was stunned, he grabbed Jiang Yan's hand and shook it.

According to what He Yuzhu reported to himself a few days ago, no less than 10,000 kilograms of bacon have been processed, and there is also a lot of processed meat in the newly built cold storage of the institute.

There are also many delicacies such as dried mushrooms and fungus, but these are basically exchanged for supplies, so much so that they used up two months of bills for everyone in the entire institute. Just these supplies, the director Almost all their connections were used. But he is enjoying it now.
