Siheyuan starts from a better life

Chapter 104, Converter Oxygen

"Boss, today I'll take your "cub" to work." At the dinner table, Xu Damao ran out after eating in twos.

Then He Yuzhu hurriedly finished his meal and ran out.

Seeing these two people, Jiang Yan was a little speechless.

At this time, Shi Shi, who was also eating at the dining table, said, "Boss, today I will ride your bicycle to work."

Hearing Shi Shi's words, Jiang Yan nodded.

Xu Damao and He Yuzhu are arguing over who will sit in the funnel, and the fight is that they will not let the other be red-faced.

Jiang Yan, who was about to ride a bicycle, saw this situation and shouted directly: "Zhuzi sits in the funnel, and Da Mao sits in the back."

"Boss, why can the pillar sit on the funnel."

Hearing Xu Damao's words, Jiang Yan spoke helplessly. "He has a big physique, and he is crowded in the back."

Hearing Jiang Yan's words, Xu Damao looked at himself and at the car seat, and could only sit helplessly behind Jiang Yan and Xiaoliuzi.

After everyone got on the motorcycle, Jiang Yan stepped on the gas, the motorcycle started, and he rode to the rolling mill in a hurry.

In the blink of an eye, it had been two days since Jiang Yan came back to the rolling mill. At this time, there were a lot of straw papers full of words scattered on the ground in Jiang Yan's office.

Finally, after finishing the calculation, Jiang Yan rubbed his sore wrist, and glanced at the formula and process that he had written.Nodding in satisfaction.It took almost a week before and after, and finally got it done.

It took me so long to put the data sorted out during the day on the space computer every night for calculation.

If I use these crude calculation tools in the department, I guess I can't finish it in a month or two.

Seeing these crude computing tools, Jiang Yan couldn't help but admire those seniors who used these tools to grow mushroom clouds.

Jiang Yan got up and put the organized materials into the safe.

After putting it away, Jiang Yan picked up the phone and dialed the number of the guard room on the second floor, asking the guard to notify the cleaning staff to clean up his room and request that all written paper be destroyed in accordance with the regulations.

After putting down the phone, Jiang Yan left the office and walked to the fifth workshop.

The fifth and sixth workshops of the rolling mill are also called steelmaking workshops. It should be understood literally that the main function of these two workshops is to make steel.

Most of the steel required for the production of the rolling mill is produced by these two workshops.

"Jiang Gong, why are you free to come to our workshop today?"

In the rolling mill, Jiang Yan is almost always referred to as section chief on formal occasions, but workers prefer to call Jiang Yan Worker Jiang.

"Why, Director Guo, I hear you are making a fuss! What you mean is that I blamed me for not talking about our steelmaking workshop."

Director Guo Minghui, who was distracted by Jiang Yan's words, scratched his head in embarrassment and smiled at Jiang Yan.

Director Guo's smile, which was already very dark, set off his true white teeth.

"I'm also to blame for this matter. I should have come to our steelmaking workshop earlier. I'm here to apologize to the brothers."

Director Guo was a little embarrassed by Jiang Yan's apology.

So he directly pulled Jiang Yan into the workshop, introducing the situation in the workshop as he walked.

"Our fifth workshop and sixth workshop are the two workshops with the largest number of workers in the whole factory. Compared with the other several workshops, the work in our workshop is relatively light."

"We have three open-hearth furnaces for steelmaking in Workshop No. 300, two of which are 500T, and the other is 500T. In our entire Sijiu City, there are only these two [-]-T open-hearth furnaces."

"Our workshop plus one 300T and two 200T open hearth furnaces in the sixth workshop can produce up to 20W tons of steel per year. The steel produced can not only satisfy our rolling mill, but also supply some enterprises."

While talking, Jiang Yan could feel Guo Minghui's slow sense of pride.

Jiang Yan nodded as he listened. A heat wave swept over the workshop as soon as he entered the workshop. The workers working in the workshop were dressed in simple clothes.

Every time Jiang Yan passed by a worker, the worker greeted Jiang Yan warmly.

They also saw clearly what Jiang Yan did since he entered the factory, and they knew that Jiang Yan was a capable person.Naturally, he became more enthusiastic.

After Jiang Yan finished visiting the two workshops, he returned to his office, looked at his safe and sighed.

It seems that my share of 7075 aluminum alloy will be taken out a little later. The top priority now is to increase the production of steel and update the equipment.

Jiang Yan knew that in 1955, the country's steel output was only 285 million tons. At that time, the country's annual steel output was not comparable to that of a large steel plant in Europe and the United States.

At that time, the country's population was almost 6.15 million, and the per capita steel production increased to 4.64 kilograms.In this year, India's per capita steel production was only 4.35 kg.Although it surpassed India, North Korea had a population of only 1955 million in 907, but produced 13.7 tons of crude steel, with a per capita output of 15.1 kilograms, more than 3.2 times that of China.

Construction is going on all over the country, and it would be impossible without steel.Steel is the backbone of a nation.

When Jiang Yan visited the two steelmaking workshops just now, he noticed that the open hearth furnaces in these two workshops have been used for a long time, and the latest open hearth furnace was the equipment of the little devil more than ten years ago.

It takes about eight hours to produce a furnace of steel, and the production efficiency is too low.

In the later stage, I have to do a lot of experiments, and I urgently need an experimental workshop. I can't always go to the steelmaking workshop or other workshops to cooperate with each experiment.This is too much trouble.

Jiang Yan spread a new piece of white paper on the drawing board and began to write and draw on it.

The steelmaking furnace designed by Jiang Yan is called oxygen side-blown converter steelmaking. Air or oxygen is blown into the molten pool from the side of the furnace wall of the converter to oxidize carbon, silicon, manganese, phosphorus and other elements in the iron water, and increase the heat generation. A converter steelmaking method in which molten steel is smelted into molten steel at the temperature of the molten pool.

Jiang Yan remembered that basic air side-blowing converter steelmaking was a successful experiment after liberation, and it was a steelmaking method that was rapidly developed during the mass movement to develop steel in 20.It better adapts to the needs of local industrial and agricultural development when our country's resource conditions are not suitable, and has made certain contributions to the development and improvement of the layout of my country's iron and steel industry for more than [-] years.

The factory where Jiang Yan worked before had a 30T oxygen side-blown converter steelmaking furnace.

In my own time, this kind of steelmaking furnace has been replaced by a more advanced steelmaking furnace, but now the oxygen converter steelmaking furnace is the mainstream steelmaking method in the world.

Compared with the current open hearth furnace, this method consumes less fuel and has much higher productivity. More importantly, the cost of manufacturing the converter is only about 60.00% of the open hearth furnace.

The furnace is composed of a converter body, a tilting system, an oxygen lance and an oxygen supply system, and can be produced according to the current technological level.

Jiang Yan, the company's oxygen side-blowing converter before, did not disassemble and repair it frequently, and he is very familiar with the various structures inside.

So Jiang Yan drew very quickly, almost without any pause.After a while, Jiang Yan's side was full of drawn design drawings.

After stopping for the last touch, Jiang Yan put away all the drawings, and then wrote a detailed introduction of the oxygen side-blown converter.

After finishing writing, Jiang Yan went directly to the factory director's office.
