Siheyuan starts from a better life

Chapter 318.open the furnace

"Start feeding."

At Jiang Yan's order, the members of the commune carried the sintered ore in baskets or grain bags and put these materials into the furnace from the furnace mouth along the built slope.

"Add coal." Jiang Yan then ordered.

As soon as Jiang Yan's voice fell, people filled the stove with smelted coke, and then started to light the fire.

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

To practice steel, you must first ensure the temperature. Since there is no professional measuring tool, Jiang Yan can only control the temperature inside the furnace by feeling. In order to avoid the temperature leakage, Jiang Yan also specially confessed that the surrounding of the furnace is made of yellow mud with straw Seal it again.

"Boss Jiang, you've worked hard." Ma Youcai, who was standing there, hurried over when Jiang Yan finished his work.

"It's all for the people. It's okay if there is any hard work. The manpower is arranged here. The fire can't be stopped. I will also send technicians to follow."

After listening to Jiang Yan's words, Ma Youcai nodded in a hurry.

"I'll arrange it here, and it must be arranged, Mr. Jiang, the first batch of red bricks will be released soon, and I will trouble you to take a look."

Jiang Yan nodded,
They followed them to the kiln where refractory bricks were fired before.

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

Taking advantage of free time, the square in front of these kilns is already filled with ready-made brick embryo cakes.

"The fire has gone out!" Jiang Yan asked the technician in his research institute there.

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

"Then start the kiln and pay attention to safety." Jiang Yan patted the technician on the shoulder after saying this.

"open kiln"

As soon as the words fell, the blue bricks that originally sealed the kiln mouth were removed by the members, and the heat wave also came out of the kiln. Feeling the heat wave, Jiang Yan took two steps back.

The sealing bricks at the kiln entrance were removed, and the personnel who had been arranged for a long time began to go in and take out the fired red bricks.

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

"Xiao Hu, look, this should be because the temperature is too high, and the firing temperature of the next batch will be lowered a little." Jiang Yan held the bricks and said to the technicians of the research institute who are now instructing them to fire.

The technician who heard Jiang Yan's words said with a look of embarrassment: "Mr. Jiang, there is no special thermometer here, and the temperature can't be controlled so accurately."

"What kind of thermometer, I'll send someone to buy it in Sijiu City immediately." Before Jiang Yan could speak, Ma Youcai who was next to him hurriedly interjected.

Hearing Ma Youcai's words, Jiang Yan told him the style and standard of the thermometer, fearing that he would make a mistake, Jiang Yan even drew a drawing for him.

"Okay, I'll send someone to buy it now." Ma Youcai took the blueprint and hurriedly arranged for the members to go to Sijiu City to buy the blueprint.

"After the kiln is opened, the technicians you train will fully accept it, and you will only be there to guide, understand?"

"Understood, Mr. Jiang."

Hearing Xiao Hu's words, Jiang Yan nodded.

It's been half a month since I didn't know it, and I've finished what I should do. Yesterday when He Yuzhu sent the bacon back, he told himself that all the parts of the trial-produced tricycle have been produced, and the mold of the engine has also been produced according to the drawings. When he came out, he was waiting for Jiang Yan to go back to guide the installation of the engine, and he was only waiting for the first batch of steel to be smelted before going back to preside over the assembly of the tricycle.

Thinking of this, Jiang Yan turned his head and returned to the small blast furnace.

Jiang Yan who returned to the small blast furnace did not say a word, quietly watching the changes in the small blast furnace.

As the furnace temperature continued to rise, the ore in the furnace gradually melted and turned into red molten iron.

The members of the commune 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, no qualified steel can be produced.

Then the blower device continued to blow the wind, and several strong men chanted and pushed the blower device hard.

A large amount of air is blown into the blast furnace, on the one hand to continue to increase the temperature of the furnace, on the other hand to allow the oxygen in the air to react with 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 relatively brittle, that is, pig iron.The carbon content is low, and the iron produced is too soft, that is wrought iron.

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

Over time, the molten iron contains less and less carbon and begins to shift in the direction of steel.

Jiang Yan led the technicians to keep an eye on the status of the molten iron, and estimated that it was almost there.

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

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

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 smoking white smoke.

When the steel ingot cooled down, the technicians hurried forward to examine it carefully, and even reached out to touch the still hot steel ingot.

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

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

Jiang Yan didn't speak. He picked up the refined steel block and took a look. The color of the steel block that should have been white was a bit gray. When he saw this color, he knew what the technician said was right. However, even such a relatively low-end steel I don’t know how many times the molten iron melted with iron tools has improved. That’s iron, but this is steel!
"Leader Jiang, this is steel, and we have succeeded." Ma Youcai doesn't care about the quality of the steel, as long as he can produce steel, it is a huge political achievement.

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

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

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

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

"Hurry up, send this steel block to the county government to announce the good news." After cheering, Ma Youcai arranged for the members to bring the steel block to the county to announce the good news, but they came directly to Jiang Yan.

In Jiang Yan's dazed effort, he grabbed Jiang Yan's hand and shook it.

"Thank you, Leader Jiang, for your selfless help. Needless to say, all the unplanned materials in our Shili Township will be given to your research institute in the future."

Hearing this, Jiang Yan wanted to laugh a little, even if he didn't say that, the village below him would also provide us with unplanned supplies.

What Ma Youcai didn't know was that Xu Damao had been completely liberated since the technicians who came to support from the research institute were in place. He used this gathering to get acquainted with almost all the captains, and then relied on With his eloquence and some supplies that are in short supply in the countryside, he soon became the guest of these captains.

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

As a result, Xu Damao collected a lot of meat and delicacies from the hands of the captains by using some materials such as iron pots and agricultural tools.

With the cover of these captains, Xu Damao even organized some hunters with better skills to go hunting in the mountains.

Now there are a lot of prey in this mountain, and the harvest has been quite good in the past half a month, and the jeep will send the collected supplies back to Sijiu City every day.

Due to the hot weather, He Yuzhu made most of the collected meat into bacon.

They even hired bricks to build a house for making bacon and bacon in a not-too-distant mountain valley, and a few people from the back kitchen of the research institute came to help.

According to what He Yuzhu reported to himself a few days ago, the processed bacon weighed more than [-] catties, and a lot of processed meat was also stored in the newly built cold storage in the institute.

There are also a lot of delicacies such as dried mushrooms and fungus, but these are basically exchanged for materials, so that they used up the two-month bills of all the people in the research institute. Only these materials, the director Almost all of their contacts were used.But now he is enjoying it.
