Qin Daniu wanted to say something else, but was stopped by Qin Fengshou.
Then I heard Qin Fengshou say in a loud voice: "Leader! We have finally arrived. Our village is too far away. We are late. I'm sorry, I'm sorry!"
Just as Jiang Yang was about to say something, He Yuzhu pulled him back and gave him a wink. When he turned around, he saw the commune personnel walking towards them.
"Leader, do you know this person from Qinjiazhuang?" The commune staff walked up to Jiang Yan and the others and asked a little doubtfully.
"I don't know them. How could I know them? Aren't they the leaders of the commune?" Qin Fengshou showed an honest smile as he spoke.
"They are the big leaders from the Forty-Nine City Research Institute. The institute knows about it! They are full of great scientists. They are here to help us make steel. I don't know how to say hello."
Hearing that they didn't recognize them, the commune workers who rushed over breathed a sigh of relief and scolded them.
"Okay, Lao Qin, you are the last one every time. Hurry up to your place and see that Hongjia Village is just like you. They have been here a long time ago."
After hearing the reprimand from the commune personnel, Qin Fengshou didn't say anything. After giving He Yuzhu and the others a wink, he quickly led the people from Qinjia Village to their station in the distance.
Because I arrived too late, I could only go to work in the fringe areas farthest from the commune.
"What's going on with them?" Jiang Yan couldn't help but ask the commune personnel as he watched them leave.
Seeing the puzzled faces of Jiang Yan and others, the commune personnel explained.
This Qinjia Village is located near mountains and forests. Although there is a lot of land, the fertility of the land is limited, the harvest is not good, and life is relatively difficult. He does not dare to mention the word "poor" in particular.
They are recognized as "backward elements" by the commune, and even the people in Hongjia Village, not far from them, look down upon them.
Jiang Yan nodded secretly after hearing this. It turned out that he came to Qinjia Village to hide his clumsiness.
"Boss, why are you here? Our Director Ma is going crazy looking for you." After Jiang Yan, He Yuzhu and the others basically turned around every blast furnace, they just sat there and rested for a while. A commune employee He ran over sweating profusely.
"Where are they?" Jiang Yan threw away the cigarette in his hand and asked.
"In the conference room, I will take you directly there."
Jiang Yan nodded without saying a word, stood up and followed the commune staff into the conference room.
"Mr. Jiang, are there any problems with our construction of these blast furnaces?"
As soon as Jiang Yan sat down, a fat man in a Chinese tunic suit asked.
Jiang Yan was stunned when he heard his name, looked at him with some confusion and asked, "Do you know me?"
"Mr. Jiang, I am Zhang Yuanchao, a fourth-level worker in our steel rolling mill. The leader sent me to help the farmer brothers in steelmaking."
Hearing this, Jiang Yan glanced at the man sitting there at the steel rolling mill, his face darkened.
"Look at what you are building. How many of them are qualified? Tell me! Can you make steel like this?"
Hearing Jiang Yan's words, Zhang Yuanchao lowered his head and defended in a low voice: "Mr. Jiang, I can't help it. The building materials are limited, so I can only find a temporary solution."
Then he began to explain the sources of all the materials, which also opened Jiang Yan's eyes.
For example, when lining a small blast furnace, fine fiber like flax must be mixed into the mud, but the amount required is so large, where can the fiber be obtained?
If fine linen was not available, they used human hair instead. There was no refractory soil, so they smashed the water tanks at home and pounded them so that they could have refractory soil.
Without refractory bricks, they thought of using blue bricks, red bricks, or even adobe bricks for construction. Hundreds of small blast furnaces, large and small, were built using such materials. The quality can be imagined.
Ma Youcai, who was sitting there, also understood the conversation between Jiang Yan and the others, and asked Jiang Yan in a low voice: "Leader Jiang, you said that we can't make steel because this small blast furnace is not up to standard."
Hearing Ma Youcai's question, Jiang Yan thought for a moment and said directly: "It's not just a problem with the small blast furnace, the temperature is also the most important thing. Without high temperature, steel cannot be made."
"Then what do we need to do?" Ma Youcai asked next.
"Knock down all the unqualified blast furnaces, rebuild them, and find a place to burn carbon and make steel." Jiang Yan's words were unequivocal.
"Then what if everything is pushed back to reopening and this is a mistake in steel training? No one can bear the responsibility for failing to complete the higher-level tasks." A commune worker sitting next to Ma Youcai spoke up.
"I'm going to come up with a solution to the problem. Whether you do it or not is up to you. If you don't do it, I'll help you complete it. If you don't do it, I'll turn around and leave now."
He wanted to take responsibility for himself without even thinking about it.
When the club member who just spoke heard Jiang Yan's words, he understood that Jiang Yan had clearly seen Xiao Jiujiu in his heart.
After their deliberations, Ma Youcai finally made the final decision to dismantle the blast furnaces that had not yet been repaired, and continue to make steel in those blast furnaces that were currently producing steel.
And Jiang Yan drew a blueprint for a new small blast furnace in front of them.
He asked, who was also shocked by Jiang Yan's move.
The small blast furnace designed by Jiang Yan is different from the "earth blast furnace".
First of all, his method of building the furnace is different. The furnace shell is made of steel plates, lined with refractory bricks, and has a vertical cylindrical shape.
Next is the chief of the furnace. Generally, such a blast furnace can produce continuously for several to more than ten years.
Jiang Yan also completely abandoned the mechanical parts inside based on the situation of putting it down. From loading, air supply, slag discharge to tapping, the entire production process is entirely manual.
And it has a large volume. This furnace is the fifth furnace of the earth blast furnace.
However, its requirements for fuel are relatively high. Except for a few conditionally used coke or coal, the vast majority of "earth blast furnaces" use charcoal; iron-making blast furnaces must use high-strength, low-ash, Low sulfur coke.
In addition to proposing the construction of coke-smelting pools, Jiang Yan also proposed "coal-free sintering" in earth sinter mines invented in the 1970s.
All Jiang Yan did was improve quality.
To improve quality, efforts must be made from three aspects: raw material management, furnace operation, and equipment maintenance. Strengthening raw material management is particularly important. The central requirement for improving pig iron quality is to minimize the sulfur content in pig iron. Sulfur comes from coke and ore. To eliminate it, we must first control the raw materials and restrict them from entering the furnace.
By eliminating sulfur from raw materials to the minimum, desulfurization in smelting will be easier to handle. In desulfurization before smelting, the contradiction is simple, the operation is simple, and you get twice the result with half the effort; bringing a large amount of sulfur into the furnace for processing will cause a series of changes in the slag-making ingredients in the furnace, which is much more complicated than desulfurization before smelting.
The basic requirements for raw material management are "coarse grains and fine grains" and "fine grains and fine grains", so that the blast furnace can eat fine grains and clinker. By doing this, the improvement of pig iron quality will be the most basic guarantee. But this requires a series of detailed work.
Jiang Yan explained his thoughts to the drawings in relatively plain terms, and almost everyone working on it could understand Jiang Yan's design ideas.
"Leader Jiang, is this expensive?" Ma Youcai raised the most realistic question.
"It's not high. We can ask the rolling mill for help for the internal steel. I'll call Director Yang of the rolling mill later. We can build ten of these small blast furnaces and that's about it."
"Okay, since Leader Jiang said so, we will do what you say. If nothing else, we will follow your request in terms of manpower. All of us in the commune will obey your command."
