Siheyuan: Craftsmen of a Great Country

Chapter 305 Data Report, High Quality Steel

In the largest conference room of the Ministry of Industry, the old man was sitting at home, and next to him was the chief.

Other people who came to inspect and the leaders of Sansteel Group also gathered here.

They are all waiting for the test results to come out.

In the laboratory, there are many restrictions, and it is inconvenient for ordinary people to go to the toilet, so in the end everyone chooses to wait here.

The old man had something on his mind and kept silent.

Others dared not speak.

They didn't know that the two chiefs were in a good mood before, but why it changed after they went out.

Could it be said that they discovered the problems of Sanshan Iron and Steel Group, which were relatively serious.

Tao Yuan's heart was even more tense.

Start recalling carefully, and there shouldn't be any problems.

He Shen held his eyes, took the report, and read it carefully.

In the entire conference room, Jiang Chen was probably the only one who knew why the mood of the two leaders had deteriorated.

This is no small matter. It was not easy for the two of them to leave without rolling up their sleeves.

"In the element detection, the contents of oxygen, nitrogen, carbon, silicon, sulfur and other elements are very low, and the separation efficiency is very high."

Looking at it, his face showed joy: "Old man, this is good steel."

The entire testing process is followed by people around the elderly person.

Just after two hours, Yang Weimin ran into the conference room out of breath with the report: "The test report is out."

However, he did not dare to guarantee it. After all, there were tens of thousands of employees in the No. 3 Steel Plant. Too many people would inevitably result in inadequate management.

"Yield point, pressure resistance, fatigue resistance and other aspects of performance are all superior."

Fitting is a technical term that many people don’t understand.

"Judging from this data alone, the comprehensive performance of steel refined in this way is at least 20% higher than that of ordinary steel, and it is considered high-quality steel."

It is full of various data, with only one standard parameter for comparison, which is incomprehensible to non-professionals.

The staff then handed it to the elderly.

The old man glanced at it, turned around and handed it to the next person: "29.9 tons."

After all, the gap between what I saw before and what I just heard is too big.

The guard who followed him handed the report to the staff of the old man's home.

The report did not go through Yang Weimin's hands. He was only responsible for following up on the progress.

"Comrade He Shen, you are an expert in this field. Please read this report."

After all, not everyone knows whether each parameter is better than the standard parameters or lower than the standard parameters.

"The mechanical and process performance tests show that the hardness, tensile, compression, bending, flattening, impact, drop weight, torsion, winding, bonding, welding and other parameters of this steel are all excellent, much better than ordinary steel. .”

Fortunately, in the end, the correct conclusion that everyone can understand is given: high-quality steel.

The old man finally felt better and turned to ask Jiang Chen: "Comrade Jiang Chen, I just saw that the output of this furnace of steel is 29.9 tons?"

Jiang Chen stood up: "Yes, we are equipped with raw materials according to the 30-ton standard, but there are inevitably losses and errors in the steel-making process, so the final steel produced is 29.9 tons."

Of course, the configuration of this raw material is definitely not the result of theoretical calculation.

It is based on the data obtained from previous experiments.

Because no matter how advanced the steelmaking technology is, it is impossible to convert 100% of the raw materials into steel.

The slag will also take away some of the iron oxide that has not yet fully reacted.

These are inevitable. The old man nodded: "Then tell me, according to our current production level, how many tons of steel can we produce at most from one furnace?"

Jiang Chen has long thought about this problem: "Converter steel-making furnaces are getting larger and larger, and the production efficiency will be higher and higher, but the process will also be more complex."

"And under the condition of ensuring safety, the furnace charge should be controlled between one-sixth and one-seventh of the converter capacity."

"So, according to our current production level, we can build a composite blowing converter steelmaking furnace with a steel production capacity of 200 tons. When the subsequent conditions are mature, we can try a 300-ton or even larger furnace type."

The steel production capacity of the converter is not bigger, the better.

Expanding steel production requires many considerations.

The first thing to bear the brunt is the carrying capacity of the converter itself.

The materials used to manufacture the converter, the output power of the motor, etc. will all limit the load capacity of the converter itself.

Secondly, the load capacity of supporting facilities must also be considered.

If the converter is too large, it will greatly increase the construction cost of the converter itself, as well as the suffering and operating costs of supporting facilities.

When these increased costs exceed the cost of a new converter, it is a loss-making business.

Even for flower growers in the original world, in the 21st century, the largest converter type is only 350 tons.

Therefore, Jiang Chen reported a relatively conservative figure.

The old man nodded: "One furnace is 200 tons. Even if it is refined eight times a day, it is 1600 tons."

"Excluding holidays, Sunday, even if he still has 250 days, he can refine it in a converter."

The staff behind who were good at calculations gave the result: "40 tons."

The old man became enthusiastic: "In other words, with 30 converters, we can produce 1200 million tons of high-quality steel."

Jiang Chen added: "If steel is made in a hot furnace, the refining time can be shortened slightly. Of course, the premise is that the molten iron can keep up."

The old man nodded, turned around and asked, "Comrade Xinjian, how many steelmaking furnaces do we have in the country now?"

Zhou Xinjian swallowed and reported a figure with lingering fear: "If we add all the earthen blast furnaces in the country together, there are more than 200 million."

When Zhou Xinjian answered, the old man stretched out his hand, and someone immediately handed over relevant information.

The old man looked at the data above and sighed: "Let me read you a set of data. In the Central Plains province alone, there are more than 45 furnaces, 000 million steel troops mobilized, and 360 various transportation vehicles."

"There are more than 200 million furnaces in the country. How many people, how many vehicles, and how many materials are required to produce 800 million tons of qualified steel?"

"Comrade Xin Xin, your Ministry of Industry must reflect on this."

Zhou Xinjian did not dare to express his anger: "Yes, our Ministry of Industry must reflect on it."

In fact, he is quite innocent. This plan was not proposed by their Ministry of Industry.

Fortunately, the old man did not delve into it: "Now that Comrade Jiang Chen has developed a more advanced and efficient steelmaking method, 30 furnaces can exceed the current two million."

"Your Ministry of Industry must seize the time to promote this advanced steelmaking method and increase steel production."

Zhou Xinjian nodded: "Okay, we will definitely seize the time to implement this converter steelmaking method and carry out rectification and upgrading of large steelmaking plants across the country."

What did the old man think of again: "Keep it secret. The West has blocked us and won't give us advanced technology and machines. We can't give them our own research results."

Zhou Xinjian nodded and asked, "What about the existing earthen blast furnace?"

The old man said: "We will discuss this matter after we go back and study it."

In fact, everyone knows that converter steelmaking will become the mainstream method of steelmaking for farmers. These inefficient and quality earthen blast furnaces will only have to be shut down.

They have lost their meaning of existence.

This is a good thing.

At least, the energy and time spent on steelmaking can be returned to the fields to deal with the upcoming three years.
