"Come, come, everybody pour the wine." While speaking, Jiang Yan poured wine into his wine glass.

After seeing everyone pour wine, Jiang Yan raised his glass and said: "I won't say anything else, all of you here are my elders, I hope to cooperate with you in the future, we can develop more and more advanced machines together, and provide assistance for the development of our country, come and toast." ”

After Jiang Yan finished saying this, he first drank the wine in his cup. The other people saw Jiang Yan drink the wine, and they also finished the wine in their hands.

After the banquet, the drunk Jiang Yan was sent back to the house by He Yuzhu and them.

Maybe I've been too tired lately, plus I've drunk a little bit more. The next day, Jiang Yan was woken up by He Yuzhu.

After hurriedly eating breakfast and saying hello to grandma, Jiang Yan and He Yuzhu hurriedly walked towards the rolling mill.

Jiang Yan was drunk last night, and He Yuzhu and they couldn't ride a motorcycle, so the motorcycle could only be placed in the rolling mill.

And Jiang Yan's bicycle was borrowed by Tian Zao to be used by the main household in the community for marriage, so he can only go to work with his legs today.

By the time Jiang Yan arrived in the workshop, everyone was already waiting.

"Are things ready?" Jiang Yan asked Director Guo, who was waiting there.

Before attending the celebration banquet yesterday, Jiang Yan handed over the things he needed to practice steel the next day to Director Guo Minghui, and he prepared them.

"Jiang Gong rest assured, it's ready."

Hearing Director Guo's words, Jiang Yan didn't talk nonsense, and directly began to command where.

"Fill in the coke and prepare for preheating."

As soon as Jiang Yan's words fell, several workers pushed several truckloads of coke into the steelmaking furnace.

Seeing that coke has been put in. Jiang Yan, who was standing on it, shouted: "Ignition"

The coke is ignited and the converter is preheated.

At the end of the preheating of the converter, Jiang Yan instructed the workers to rotate the converter and align the furnace mouth with the feeding area.

Workers put prepared molten iron and also iron ore.

The main raw material for oxygen side blowing converter steelmaking is molten iron, and the temperature of this molten iron is between 1200~1300°C.

Jiang Yan saw that the raw materials had been added, and instructed the converter to turn to the blowing position, and inserted the oxygen gun into the furnace from the furnace mouth to blow oxygen. Oxygen rapidly oxidizes carbon, manganese, silicon, phosphorus and other elements in molten iron, and at this time it is added to scrap steel, and a large amount of heat is released at the same time. At this time, flames and smoke came out of the furnace mouth.

After seeing that the smoke was already rising, Jiang Yan instructed the workers to add slag materials such as lime and fluorite to the furnace to establish conditions for the removal of sulfur and phosphorus.

Jiang Yan looked at his watch while observing the refining of the materials inside. The oxygen blowing time of a furnace of steel is generally 12 to 18 minutes, and since it is the first steelmaking, Jiang Yan controls the oxygen blowing time at 15 minutes. Seeing that the time had come, Jiang Yan shouted loudly: "Stop blowing oxygen, pull out the oxygen gun." ”

When the worker in charge of blowing oxygen heard this, he quickly turned the machine and pulled out the oxygen lance and turned them off.

Jiang Yan looked at the temperature gauge attached to the converter while observing the converter.

After the temperature reached 1600 °C, Jiang Yan shouted loudly: "Add deoxidizer and prepare to tap steel." ”

The reddish molten steel flowed out of the taphole and along the tapping track, and the workers in charge of cooling and continuous molding began to get busy.

With the full cooperation of everyone, with residual warmth, the white steel block soon appeared in front of Jiang Yan and them.

Seeing that the molten steel in the furnace had been completely poured out, Jiang Yan instructed the workers to clean up the residue in the furnace and prepare for the next furnace of steel.

However, this time it was just a test, and Jiang Yan instructed the workers to extinguish the fire.

At this time, Jiang Yan's whole body was like being fished out of the water, his whole body was wet, there was no way, the first time he made steel, Jiang Yan had to command the whole process, and watch the state of the molten steel inside, so it was also a little closer to the furnace mouth.

When testing the converter just now, Jiang Yan's spirit was highly concentrated, and he didn't feel the heat.

As soon as I was free, I felt like I was going to be dehydrated at this time, my legs went limp, and I shook my head to make myself sober.

When Jiang Yan just breathed a sigh of relief, thunderous applause came from behind him.

As soon as Jiang Yan turned around, he saw Director Zhang standing not far away with some people who looked like leaders.

Seeing this group of people, Jiang Yan was stunned. In Jiang Yan's stunned effort, Director Zhang walked over quickly and patted Jiang Yan's shoulder affectionately and excitedly.

"Little ginger! You're amazing, you're amazing! Do you know how much time it took to practice a furnace of steel? ”

Hearing Director Zhang's question, Jiang Yan was a little dazed, he only cared about the situation of converter refining just now, where could he take care of time!

Seeing Jiang Yan's dazed face, Director Zhang said to Jiang Yan with a smile: "Thirty-four minutes, thirty-four minutes to practice a furnace of 20T high-quality steel." ”

"Our rolling mill usually uses an open-hearth furnace to smelt a furnace of 20T steel, which takes eight hours. The time it takes to clean up the slag and prepare the materials, we have no problem producing a furnace of steel in two hours, which means that our output is quadruple, quadruple! ”

When he said this, Director Zhang's eyes were red, seeing that he was about to enter the rampage mode, Jiang Yan was so frightened that he hurriedly grabbed him, and kept saying: "Factory Director, calm down, calm down, there are leaders behind!" ”

Jiang Yan's words calmed down Director Zhang, "I'm sorry! Little ginger, I'm out of shape, out of shape. ”

Hearing Director Zhang's words, Jiang Yan patted him on the shoulder.

Jiang Yan understood Director Zhang's heart very well at this time, after all, every rabbit has a dream of a great country in his heart.

At this time, Director Zhang remembered that there was a leader behind him, and hurriedly pulled Jiang Yan and walked to the front of the leader.

He said to the leader with glasses and an elegant appearance: "Old leader, he is Jiang Yan, the engineer of our rolling mill, and this converter was designed and built by him. ”

This person who received Jiang Yan recognized him at a glance, he was the big leader who intersected with He Yuzhu in the TV series.

However, the time may be different, this leader looks a lot younger than in the TV series, and he is more elegant.

Seeing that Jiang Yan was a little stunned, Director Zhang couldn't help but poke Jiang Yan with traces, and said, "This is Minister Zheng of our First Machine Department." ”

At this time, Jiang Yan came back to his senses, quickly rubbed his hand on his clothes, and clasped Minister Zheng's outstretched hand with both hands.

Minister Zheng smiled and said to Jiang Yan in his Mandarin with a Sichuan accent: "You little ghost, I know you, your name is like thunder in our place, and you can toss something out no matter where you go." ”

"There is also Lao Liu, who has just established the Sijiucheng Automobile Accessories Factory, but he has not mentioned you less, but he has asked you to be transferred over many times."

"I didn't expect you to be so good at machinery, you can also repair cars, you kid is still an all-rounder, it seems that we still underestimate you, I don't know what you can toss out in the future!"

Minister Zheng's words surprised everyone! There is a kind of meaning of giving Jiang Yan a platform in and out of his words, and he also named Jiang Yan, a person who is also worth many people's attention to him.

At the moment, everyone looked at Jiang Yan thoughtfully.
