Chapter 315, Small Blast Furnace

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 really 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.

"If I don't know them, how could I know them? Aren't they the leaders of the commune?" Qin Fengshou showed a simple and honest smile as he spoke.

"They are the big leaders from the Forty-Nine City Research Institute. The institute must know 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 guys. They have been here a long time ago."

Upon hearing the reprimand from the commune personnel, Qin Fengshou didn't say anything. After winking at He Yuzhu and others, 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.

The basic requirements for raw material management are "coarse grains and fine grains" and "fine grains and fine grains", allowing the blast furnace to eat fine grains and clinker. If these are achieved, the improvement of pig iron quality will be the most basic guarantee. But this requires a series of meticulous measures.

work.

Jiang Yan was startled when he heard his name. He looked at him with some confusion and asked, "Do you know me?"

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.

Then he began to explain the sources of all the materials, which also opened Jiang Yan's eyes.

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."

Secondly, the furnace manager. Generally, such a blast furnace can produce continuously for several to more than ten years.

"Leader, 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.

The small blast furnace designed by Jiang Yan is different from the "earth blast furnace".

If there was no fine linen, they used human hair instead. If there was no refractory clay, they smashed the water tank at home and smashed it to create refractory clay.

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.

Jiang Yan nodded without saying a word, stood up and followed the commune staff into the conference room.

Eliminating sulfur from raw materials to a minimum will make desulfurization during smelting easier. When desulfurizing 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 problems in the furnace.

A series of changes in the internal slagging ingredients are much more complicated than desulfurization before smelting.

Jiang Yan nodded secretly after hearing this. It turned out that he came to Qinjia Village to hide his clumsiness.

"I'm going to come up with a solution to the problem. It's up to you whether you do it or not. 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."

"Then what do we need to do?" Ma Youcai asked next.

All Jiang Yan does is improve quality.

For example, for the lining of a small blast furnace, fibers like fine flax must be mixed into the mud, but the amount required is so large, where can one get the flax?

Jiang Yan drew a blueprint for a new small blast furnace in front of them.

"Then what if everything is pushed back to reopening and this is mistaken for 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.

He asked, who was also shocked by Jiang Yan's move.

"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."

"What's going on with them?" Jiang Yan couldn't help but ask the commune personnel as he watched them leave.

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."

They are recognized as "backward elements" by the commune, and even the people in Hongjia Village, not far from them, look down upon them.

If you want to improve the quality, you must work hard from three aspects: raw material management, furnace operations, and equipment maintenance. Strengthening raw material management is particularly important. The central requirement to improve the quality of pig iron is to minimize the sulfur content in pig iron. Sulfur comes from

Coke comes from ore. To eliminate it, we must first control the raw materials and restrict them from entering the furnace.

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.

"Mr. Jiang, are there any problems with our construction of these blast furnaces?"

"In the conference room, I will take you directly there."

Seeing the puzzled looks on the faces of Jiang Yan and others, the commune personnel explained it to them.

"Where are they?" Jiang Yan threw away the cigarette in his hand and asked.

"Look at what you are building. How many of them are qualified? Tell me! Can you make steel like this?"

As soon as Jiang Yan sat down, a slightly fat man wearing a Chinese tunic suit asked.

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.

Hearing this, Jiang Yan glanced at the man sitting there from the steel rolling mill, his face darkened.

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."

When the club member who just spoke heard Jiang Yan's words, he understood that Jiang Yan had clearly seen the little Jiujiu in his heart.

"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.

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.

Moreover, it has a large volume. This furnace is equal to 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 materials due to their large volume and high material column.

Low sulfur coke.

He wants to take responsibility for himself without even thinking about it.

Jiang Yan explained his thoughts to the drawings in relatively plain language, and almost everyone working on them could understand Jiang Yan's design ideas.

"Leader Jiang, is this expensive?" Ma Youcai raised the most practical 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 has said this, 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."
