"Ding. Do you want to use 2000 credits to upgrade the sub-skill Steelmaking Mastery to Level 2?"

"yes!"

"Ding, congratulations to the host, the sub-skill Steelmaking Mastery has been improved, and the current level is level two."

"Ding, congratulations to the host, you have received the reward, 'Aluminum Alloy Generation Process'."

As the continuous prompts sounded, Yang Xiaotao suddenly felt that his brain was a little dizzy, as if he was drunk.

Only then did I realize that I had underestimated the impact of this improvement in steelmaking proficiency.

Compared with other sub-skills, it is much better.

Thanks to the improvement of the main skill enough and after many experiences, the body has become resistant. I closed my eyes and rested my mind. After a while, I gradually recovered.

However, Naoren still hurts a little.

After leaving the toilet, Yang Xiaotao tried to control his pace and came to his seat.

At this time, there were only two people around, Ran Qiuye and Ji Xiang.

Ran Qiuye saw something strange about Yang Xiaotao and asked with concern, "What's wrong?"

Yang Xiaotao shook his head and yawned exaggeratedly, "I didn't take a break at noon, I'm sleepy."

Ran Qiuye was suspicious. She had never seen Yang Xiaotao like this before. She had personally experienced how strong her man's body was.

"If you feel sleepy, just close your eyes."

"This is a signal from the body, telling you that it's time to take a rest."

Ji Xiang looked at the side to explain, and then said to Ran Qiuye, "It doesn't mean that if you are physically strong, nothing will happen. Sometimes, mental fatigue does not show up, but it is a very serious hidden danger."

Ran Qiuye immediately looked at Yang Xiaotao after hearing this. She knew very well that Yang Xiaotao was often busy until midnight.

"You should get some sleep, it's still early for the party."

Hearing Ran Qiuye's words, Yang Xiaotao nodded immediately.

Just lie down and sort out the knowledge gained in your mind.

I lay down on the table and closed my eyes, and the relevant knowledge about the aluminum alloy production process immediately came to my mind.

Aluminum alloy, as the name suggests, is an alloy mainly composed of aluminum. It is widely used in the industry and also plays an important role in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries.

However, this technology is not mature in China. At present, most aluminum alloys are imported. Domestic production scale is not large, and the technology is lacking. There are many problems in the products produced, and the quality is difficult to guarantee. Most of them are military industry and civilian.

There is less available.

The process first includes the selection of materials, which is actually the formula of aluminum alloy. This saves Yang Xiaotao time to deal with system bugs. Of course, Yang Xiaotao suspected that the system did not want him to obtain credits, so he simply gave them to him.

The second is the sequence of each step of processing, which involves many machines.

There are no manufacturing methods for extrusion presses or profile processing equipment, so if you want to make aluminum alloys, you must solve these machines.

As for the processing of other aluminum alloy parts, it is simple, and the steel rolling mill has just finished it.
