Siheyuan starts from a good life

Jiang Yan gave the drawings of the steel lining of the small blast furnace to Zhang Yuanchao of the steel rolling mill and ordered him to hand the drawings directly to Director Yang.

After he got the drawings and left, Jiang Yan immediately called Director Yang, and Director Yang happily arranged for production. For Jiang Yan's sake, ten small blast furnace linings were included.

For a new small blast furnace, we must first solve the problem of coke and refractory bricks. In fact, this is also simple. Coke refining appeared in our country very early. The process of coke refining is recorded in the book "Tiangong Kaiwu". Jiang Yan Just take them and use them.

The coking method is to use the ignition hole in the side wall of the kiln to manually ignite the coking coal stacked in the kiln without isolating the air in the kiln, and then rely on the combustion heat of the coking coal itself to heat the coal layer by layer (directly Fire heating part); the hot air flow formed by the exhaust gas generated by coal combustion and the large amount of unburned coal cracking products continues to burn through the fire channel on the side wall of the kiln chamber, and transfers part of the heat into the kiln (indirect heating part). The high-temperature gas flow (800c) carries unburned coal cracking products - chemical products and is discharged into the atmosphere. This process lasts for 8 to 11 days, when the coke matures, water is injected from the artificial ignition hole to quench the coke, the furnace is cooled, and the coke is peeled off.

The team's handles are basically the same old handles. These teams are led by leaders from Shili Township.

"Mr. Jiang, what's wrong? What do you need me to do?" After regaining consciousness, Ma Youcai quickly wiped his saliva with his sleeve and asked cautiously.

Jiang Yan was almost provided with money, food, clothing, housing and transportation by Ma Youcai. He really did it himself. Doing his best to provide the best and highest quality things. To put it bluntly, if the seasoning allowed, Ma Youcai would like to carry him in an eight-carat sedan chair every day.

It’s impossible not to support it! These two factories are naked political achievements. With these political achievements, everyone can take advantage of them.

After seeing off the convoy, the deputy secretary of the commune found Jiang Yan.

"So, Xiao Jiang, you won't be able to come back for these ten days and a half."

Its pure kaolin is white, delicate, soft and earthy, and has good physical and chemical properties such as plasticity and fire resistance.

"In addition, after you go, tell Xiao Jiang where he can work in peace of mind, and I will personally take charge of the trial production of tricycles, so that he can rest assured."

Now Ma Youcai has profoundly mentioned what knowledge is power. He can benefit a lot from someone else's two random ideas.

"Grandma wants to ask how long it will take for me to come back." Qin Huairu asked He Yuzhu.

There is a reason why Ma Youcai cooperated so actively. Jiang Yan not only told him in detail about the problems of this company's coke and refractory bricks, but also pointed out the direction for them.

The thought that there will be two factories in his jurisdiction in the future makes Ma Youcai feel very excited, and the wind is whistling under his feet when he walks.

"That's right, Secretary Ma, it's time for us to take pictures of the convoy transporting coal, kaolin and ore. These roads are relatively far away, so we need to prepare more."

This time, Ma Youcai personally led the team to get kaolin in Huairou County.

As for this steel mission, it can only take a back seat in everyone's minds.

"Leader Jiang, the people who are learning how to make refractory bricks and how to burn them are already gathering."

"Don't worry! Mr. Jiang, leave these to us. We all have the strength to finish it within two days. If it's not enough, we can add a few more cave dwellings."

In Forty-Nine City, He Yuzhu went directly to the director's office when he returned to the institute. After entering the director's office, He Yuzhu reported to the director in detail what Jiang Yan had told him.

In later generations, there was kaolin in the HR area of ​​Sijiu City, and it was relatively high-quality kaolin, but now this HR area is only Huairou County.

"Yes, yes, I need to prepare more. I will arrange the convoy right away. Hurry up."

Ma Youcai is also quite a thief. At the beginning of the "big battle", coal, iron ore and other ores are provided for free. If you don't take the opportunity to get more, you will have to pay for it when the battle is over.

After He Yuzhu came out of the director's office, he rushed directly to the cafeteria. Qin Huairu found where he was washing vegetables and pulled him aside.

Although this kind of indigenous coking method has a long coking cycle, low coke formation rate, high coal consumption, and high coke ash content, there are relatively few professional coke refining factories in this era, and a large part of them still use this indigenous method for coking.

As for the kaolin clay, Jiang Yan also introduced it to Ma Youcai in detail. It is the most important material for making refractory bricks.

The people who learned skills from Jiang Yan were all personally selected by the commune. They had a certain cultural background and were able to handle household chores. Several people from Qinjiazhuang were successfully selected.

"I have marked the specific height and scale on it. You can proceed according to my markings, and Comrade Xu Damao will assist you."

After Wang Honghai said this, he thought for a moment and then said: "Comrade He Yuzhu, after you finish processing the meat in the warehouse, you will lead the team and bring some of the researchers from our institute to support the small team." Jiang, this kind of project should be faster."

"Wife, wife, go home and pack some clothes for me. After I finish my work here, I will go to Shili Township to support the boss. By the way, when I go back, I will inform grandma and prepare some clothes for Damao and the boss."

Ma Youcai happily agreed and began to instruct others to do it. Looking at him like that, if he hadn't been a few years younger, he would have fallen in love with him.

Before, they had a small meeting in private behind Jiang Yan's back. With these two golden hens that could lay eggs, almost everyone at the meeting supported Jiang Yan one-sidedly and said that anyone who dared to object would be The entire Shili Township commune was an enemy.

More importantly, Jiang Yan promised to train them a group of workers who could make refractory bricks and make coke.

"Secretary Ma, Secretary Ma." Jiang Yan looked at Ma Youcai, who was a little dazed, and patted him gently.

"Here, here, and here, build several cave dwellings for making coke and refractory bricks." Jiang Yan pointed at the drawings and ordered Ma Youcai who was following him.

Kaolin is a non-metallic mineral, a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, it is also called dolomite.

Jiang Yan nodded, turned around and walked towards the playground.

"It shouldn't be too long. Just tell grandma that we will be back in a month at most."

After Qin Huairu left, He Yuzhu directed the people in the canteen to unload all the meat brought back today, and then directed the people in the canteen to marinate and air-dry the meat. He did this all night without sleeping. , it was not until dawn that the meat was processed. Hearing that the people who supported Jiang Yan had arrived, He Yuzhu washed his face and hurried to gather again with the three bags prepared by Qin Huairu.
