After instructing the other workers, Jiang Yan put on a leather coveralls with their assistance.

After getting these things done, Jiang Yan began to put the aluminum ingot at the bottom of the furnace first, and then put another layer, and put zinc with a relatively low melting point on the top.

Next, all kinds of metals were stuffed into the converter by Jiang Yan according to the proportion, especially when putting magnesium blocks, Jiang Yan was extremely careful.

After everything was put in place, Jiang Yan pressed the start button, and the temperature in the furnace began to rise, and the metal began to melt one after another according to the melting point, and as the temperature in the furnace continued to rise, all the metals melted and fused together.

Through the observation window, seeing the metal that had formed a liquid state, Jiang Yan breathed a sigh of relief.

Outside the cordon, with the help of Guo Jianjun, Jiang Yan took off his clothes with great difficulty, and at this time people found that Jiang Yan's clothes were all soaked with sweat.

"Jiang Gong, do you want to go back and change your clothes, the wind in Bingcheng is still very cold in May."

As if to confirm something, as Guo Jianjun's words fell, a wind blew into the hot workshop, bringing a cool air to the originally stuffy workshop.

Jiang Yan shivered, but he still said to Guo Jianjun: "It's okay, I'm going to observe the temperature of the furnace fire soon, where the temperature is high, it is estimated that the clothes will be dried in a while." ”

After saying this, he took the large teapot handed over by Guo Jianjun and drank the warm boiled water in it in one go.

I put on an apron made of cowhide and gloves to insulate myself, and I was about to go inside.

As soon as he took two steps, he turned his head to Guo Jianjun, who was standing there, and said, "Go back and add a little salt to the boiling water." ”

After saying this, he strode towards the oxygen blowing converter.

Through the observation window, Jiang Yan saw that the flames at this time had turned pale yellow.

Under normal circumstances, when the temperature is lower than 1000 °C, the color of the fire is reddish; In the range of 1000~2000 °C, the color of fire also fades and turns yellow; When the temperature exceeds 2000°C, the flame takes on a pale blue color.

He glanced up at the thermometer, where the temperature of the flame had reached 1860 degrees.

Alloy is a substance with metallic properties that is synthesized by a certain method from two or more metals and metals or non-metals.

Most alloys have a melting point lower than the melting point of any of their constituent metals.

Aluminum is a silvery-white metal with a melting point of 660.4 degrees Celsius, magnesium has a melting point of 648, 9 degrees Celsius, and the melting point of aluminum-magnesium alloy is higher than the two, at 650.3 degrees Celsius.

However, Jiang Yan added some different metals to this aluminum-magnesium alloy, among which the metal with the highest melting point is metal titanium, whose melting point is 1668±4 °C, and the current temperature reaches 1860, which is too hot and needs to be cooled.

Jiang Yan pressed the button, the hatch of the combustion chamber was closed less, reducing the circulation of the space inside, the space circulation was reduced, and the flame was naturally a little smaller, at this time, the thermometer showed that the temperature was dropping little by little, until it dropped to 1700 degrees, and Jiang Yan stopped the action in his hand.

Open the oxygen blowing port and start blowing oxygen. In this climate, the moisture in Jiang Yan's originally wet clothes was affected by the residual heat of the stove, and the moisture on the clothes began to evaporate.

A peculiar scene appeared, due to the appearance of water vapor, and now Jiang Yan looked at the mist surrounding his body, as if he had cultivated internal strength.

"The forging is almost over," Guo Jianjun, who was waiting for a lot of boredom, heard the voice behind him and hurriedly turned back.

It turned out that Director Zhao was not worried about the refining situation in the workshop, and felt that it should not be as dangerous as me, so he brought people to the workshop.

"Five minutes to go." Guo Jianjun looked at his watch and said.

"Is it all Xiao Jiang operating in it alone?" Director Zhao asked.

"It's him, it's been more than ten minutes, Jiang Gong has explained, and the workers are only allowed to enter and operate when the gate is opened."

In the past five minutes, all the people waiting outside felt unusually long, and Guo Jianjun and Director Zhao frequently looked at their watches.

"The master worker is in place, and there is one more minute to open the gate."

An angry roar came from inside, and the workers and masters outside the cordon heard this sound and entered in an orderly manner. According to the things that Jiang Yan explained before, they each went to their own posts and went all out.

"Open the Gate"

When Jiang Yan's voice fell, the button to open the gate was activated.

A reddish metal solution poured down the furnace mouth and flowed down the tracks.

Seeing that there was a metal solution flowing out, the workers and masters hurriedly put the prepared container at the crossing to catch the liquid flowing out.

The formed aluminum-magnesium alloy was hooked and dragged aside by the workers and masters.

Soon, the aluminum-magnesium alloy in this furnace became an alloy ingot that emitted hot gas.

"Little Jiang, how's the situation?" Seeing Jiang Yan who had just come out, Director Zhao couldn't wait to ask.

"The refining process went smoothly, and we waited until it cooled down to test it as soon as possible."

"Okay, I understand, Xiao Jiang, you've worked hard, sit down and rest, and I'll arrange someone to do the rest."

Jiang Yan was not polite when he heard Director Zhao's words, so he sat down.

At this time, he was really tired, and the clothes on his body were soaked with sweat and dried, and repeated many times, so that a thin layer of white marks appeared on the clothes.

After Jiang Yan sat down, Guo Jianjun hurriedly brought him a large glass of warm boiled water.

"There's salt in it."

Hearing Guo Jianjun's words, Jiang Yan's hand also paused, and he directly took the big tea jar and drank it, and the slightly salty boiling water entered his stomach, which was very comfortable.

After drinking the water, Jiang Yan burped again very unimpressively.

"Little Jiang, are you going to open the second furnace?" Director Zhao, who was waiting for the metal to cool, sat next to Jiang Yan and asked.

"Let's wait for the test results! However, the factory director, I suggest that if our factory really wants to refine aluminum-magnesium alloy, it is better to open a separate workshop! This workshop should be kept away from other workshops, pure magnesium, you know, is too dangerous, and it is easy to cause an explosion if you are not careful. ”

Hearing Jiang Yan's words, Director Zhao smiled bitterly, "This refining workshop in our factory is mainly for experiments and small batch production, believe it or not, once you sort out the process of refining aluminum-magnesium alloy, the superior will send engineers from other large steel plants to come over to learn." When the time comes, they will refine it, and our factory will still be dominated by the production of firearms. ”

Hearing Director Zhao's words, Jiang Yan reacted, yes, this 663 factory is an arsenal, the production of alloys is the business of the steel mill, and the rolling mill where he is located is also a steel mill, and this thing is something invented by himself, there is no reason not to participate, if his factory is really involved, maybe the level and nature of the factory will have some changes, which is good for himself and the rolling mill.

It seems that he has to fight for something, if he doesn't do anything, it is estimated that Director Yang has his own thoughts after he goes.

But you have to think about this matter yourself and see how to do it.

"Xiao Jiang, I want to wait for the results to come out and reach the predetermined value, can you bring the engineers from our factory to refine again."

"No problem, I'll bring it when the time comes."

At this time, Jiang Yan can't wait to do this! Teach the engineers in their factories to the engineers in other factories by him, and save yourself a lot of things!

I don't want to run around every day, and it's really not a beautiful thing to travel on a business trip due to underdeveloped transportation.
