Siheyuan starts from a better life

Chapter 253, Alloy Refining 2
After ordering the other workers, Jiang Yan put on the leather one-piece protective suit with their assistance.

After finishing all these, Jiang Yan started to put the aluminum ingots at the bottom of the furnace by himself, then put another layer, and put zinc with a relatively low melting point on top.

Next, all kinds of metals were stuffed into the converter by Jiang Yan according to the proportion, especially when placing the magnesium block, 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 metals began to melt one after another according to the melting point. As the temperature in the furnace continued to rise, all the metals melted and fused together.

Jiang Yan breathed a sigh of relief when he saw the liquid metal through the observation window.

Outside the cordon, with the help of Guo Jianjun, Jiang Yan took off his one-piece clothing with great difficulty. Only then did people realize that Jiang Yan's clothes were completely soaked in 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 prove something, after Guo Jianjun's words fell, a gust of wind blew into the hot and dry workshop, bringing cool air to the originally stuffy workshop.

Jiang Yan shuddered when blowing, but he still said to Guo Jianjun: "It's okay, I'm going to check the temperature of the fire soon, where the temperature is high, the clothes will probably be dried after a while."

After saying this, he took the big tea mug that Guo Jianjun handed over, and drank the warm water in it in one go.

Putting on a cowhide apron and heat-insulating gloves, I was about to go inside.

After walking two steps, he turned his head to Guo Jianjun who was standing there and said, "Add some salt to the boiling water later."

After saying this, he strode towards the converter.

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

Generally, 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 the fire also becomes light and yellow; when the temperature exceeds 2000°C, the flame appears light blue.

He glanced up at the thermometer, and at this moment the temperature of the flames had reached 1860 degrees.

Alloys are substances with metallic properties that are synthesized by two or more metals and metals or nonmetals by a certain method.

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

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

However, Jiang Yan added some different metals to the aluminum-magnesium alloy. Among them, the metal with the highest melting point is titanium, which has a melting point of 1668±4°C. The current temperature of 1860°C is too hot and needs to be cooled down.

Jiang Yan pressed the button, and the hatch of the combustion chamber was closed for less than that, reducing the circulation of the space inside. The space circulation was reduced, and the flame naturally became smaller. At this time, the thermometer showed that the temperature was dropping little by little, and kept falling. At 1700 degrees, Jiang Yan stopped what he was doing.

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

A strange scene appeared, due to the appearance of water vapor, now Jiang Yan looked at the fog surrounding his body, as if he had cultivated his inner strength.

"The forging is almost over." The bored Guo Jianjun who was waiting hurriedly turned around when he heard the voice behind him.

It turned out that Director Zhao was worried about the refining situation in the workshop, and he felt that I was not in danger, so he took people into the workshop.

"There are still 5 minutes." Guo Jianjun looked at his watch and said.

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

"It's him. More than ten minutes have passed. Jiang Gong explained that workers are only allowed to enter when the gate is opened."

These 5 minutes felt abnormally long to all the people waiting outside. Guo Jianjun and Director Zhao frequently looked at their watches.

"The master worker is in place, and the gate will open in one minute."

A roar came from inside, and the workers and masters outside the cordon heard the sound and entered in an orderly manner.According to what Jiang Yan explained before, each went to his own position and went all out.

"open gate"

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

The red molten metal poured down from the furnace mouth and flowed out along the track.

Seeing the metal solution flowing out, the workers and masters hurriedly put the prepared container on the crossing to catch the flowing solution.

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

Soon this furnace of aluminum-magnesium alloy turned into alloy ingots emitting heat one by one.

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

"The refining process is going well, wait until it cools down and take the time to check it."

"Okay, I understand, Xiao Jiang, you have worked hard, sit down and rest, and I will arrange for others to do the rest."

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

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

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

"Salt is added to it."

Hearing Guo Jianjun's words, Jiang Yan's hand paused for a moment, and he directly took the large teapot and drank it. The slightly salty boiled water entered his stomach, which was very comfortable.

After drinking the water, Jiang Yan burped again in a very unsightly way.

"Xiao Jiang, are you going to start the second furnace?" Director Zhao, who was waiting for the metal to cool down, asked while sitting beside Jiang Yan.

"Let's wait for the test results to come out! But the factory manager, I suggest that if our factory really wants to refine aluminum-magnesium alloys, we should open a separate workshop! This workshop should be far away from other workshops. Pure magnesium, you know, too It is too dangerous, and it is easy to cause an explosion if you are not careful."

Hearing Jiang Yan's words, Director Zhao smiled wryly, "The 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 alloys, The higher-ups will send engineers from other large steel factories to study. When the time comes, they will refine it, and our factory will still focus on the production of firearms."

Hearing what Director Zhao said, Jiang Yan realized that, yes, the [-] factory is an arsenal, and the production of alloys is the job of the steel factory. The rolling mill he works in is also a steel factory. There is no reason not to participate. If your factory really participates, maybe the level and nature of the factory will change, which is good for you and the rolling mill.

It seems that I have to fight for something. If I don't do anything, I guess Director Yang will have his own thoughts after going there.

But you have to think about it for yourself and see how to operate it.

"Little Jiang, I want to wait for the result to come out and reach the predetermined value. Can I bring the engineer of our factory to refine it again?"

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

At this moment, Jiang Yan is eager to do this!How much work can be saved by teaching the engineers in their factory to the engineers in other factories?

I don't want to run around every day. Traveling on business with underdeveloped transportation is really not a beautiful thing.
