CC, the fastest update material empire!

Cold Yuming and Xiao Dongping are a demon, and this enchanting is also casting a more enchanting thing at this time.

"40 chrome steel, 500 grams.

12 Chrome Nickel Steel, 300 grams.

"No. 65 manganese steel, 1200 grams ..."

Qin Hai took a piece of paper, a manual reported a number, Ningmei, Yu Haitao, Miao Lei, Wang Xiaocha, a few people are busy in a large pile of garbage, the crims, find a designated model. , Then weigh the weighing, pour in a hopper, ready for melting.

This is already after get off work, and the workers in the white class in the workshop have gone. Due to the lack of production tasks in the factory, only three or four workers in the evening workshops, and they are all living, no one cares about these A young young is busy.

Wang Xiaochen is temporarily helped by Qin Hara, because these metals need to be used in the laboratory of balance, Wang Xiaochen acts as an exploration worker, also belonging to the operator of the laboratory, with the use of balance power.

In addition, Qin Hai also found that there were several small partners to do something rough, but they would say fine weighed, but they have to make girls to do more appropriate.

Wang Xiaochen didn't know what they wanted to do. However, she is a single female worker. Anyway, there is no matter what it is, and Qin Hai calls her to help, she leaves it.

I saw that Qin Hai had a plate with a plate, she felt very mystery.

"Well, it is finally flat."

Qin Hai put down the note in his hand, wiped the sweat on his head, said if it was relieved.

This alloy steel that Qin Hai is a super high-strength alloy steel that has been developed in the early 21st century. In this era, the theory of this alloy steel has not been raised.

Through precise control of alloy steel chromium, manganese, vanadium, molybdenum, silicon, etc., plus special heat treatment processes, the strength of this alloy steel can be more than three times higher than the general high strength steel. In the later generations, it is used to make important force components such as the landing gear.

Only relying on some scraps as raw materials, plus smelting equipment is also relatively simple, Qin Hai clearly, the alloy steel that you smelted is definitely not the theoretical best performance, but it is used to make a military dagger, absolutely a small use .

He dares to ensure that the army's nephew is absolutely impossible to find a better material than this steel.

It is possible to fill the formula of ultra-high intensity alloy steel from all kinds of alloy steel waste from all walks of life, and there are many brain cells in Qinhai.

Different metal elements contained in alloy steels, the number of waste is different, which is equivalent to solving a linear planning problem with several constraints.

Fortunately, Qin Hai's mathematics context is quite quite good, such a complex problem actually made him solve.

"Can you make a steel water now?"

Miao Le Yue wants to ask.

"Yes.

Qin Hai replied.

There is a 150 kg of small work-frequency induction electric furnace, which is usually used to cast some small workpiece blanks.

At this point, Qin Hai is grateful to Weibellin. If Wei Baolin has changed the management system of the factory, Qin Hai can not be so free to use the equipment in the workshop to do its own private life.

The electric furnace is started, and the furnace temperature is raised, and those scraps in the furnace began to make a rumbling sound.

Such an electric furnace has a function of electromagnetic stirring. After scrapped into a steel water, it will be fully mixed in the furnace so that the distribution of various elements in the steel water becomes uniform.

The eyes of Qin Hai stared at the temperature meter on the electric furnace, constantly adjusting the power of the electric furnace, ensuring that the temperature controlled in the furnace is at the designated level, neither high or low.

The smelting process lasted for nearly half an hour, and the Qinhai issued a warning to everyone: "Well, everyone will rely on the steel.

Everyone retreated, only a few pre-made sand molds were left at the scene.

This sand mold is when you go to work during the day, Ningmei's drawings that are designed with Qinhai make people, this is not worthless at the foundry workshop.

The Qinhai in the former world did not personally drove the work of casting, but his predecessor is a student who studies cast professionalism, so it is not strange to cast operation.

He press the motor button, the electric furnace is turned over, pour the orange steel into the sand mold.

The steel water exudes a burning, flowing in the cavity of the sand mold, and then gradually cools the condensation, turning a blue-blue metal.

"What are you doing?"

There are workers who have been evening teachers to see the lively, and they ask.

"Do something little thing.

Ningmei is unknown.

"Haha, you have done private life, in case of the director of the seedlings, you can have a good look."

The worker threatened.

"Master Chen, you can rest assured, I have said with my father, he agreed.

Miao Lei replied half a holiday.

He really really greeted Miao Fu South, but he said the reason is to accompany Qinhai to do some material experiments.

Miao Fu South knew that his son will sneak your own private life, since the whole factory workers are doing this, he will be lazy to restrict his son, so for such a thing, there is always a close eye. of.

After the workpiece is cooled, it needs to be machined first, that is, drilled in a metal cutting machine such as a lathe, milling machine, etc.

Qin Hai is a thoughtful person. He took into account the requirements of machining equipment, so the strength of the steel he chose was not high before heat treatment, and it was able to cut treatment with ordinary machine tools.

After the ultrahigh strength of the material is completed, it is achieved by a series of heat treatments.

Machine processing, only workers who can find night shifts to the goldworks workshop, Ningmels have taken this, holding a bunch of workpieces to find someone to help.

I don't know if it is because of Ning Zhongying, Ningmei is extremely good in the factory, almost finding who is helping each other will give face.

Of course, Ningmei is not a person who has no eyes, please help the family, the cigarette throwing the bag of eight cents in the people's toolbox, showing thanks to the minimum things.

Because there is a lot of places that need to be found, I sent a whole cigarette for a night, and the money earned in the day before yesterday.

However, Ningmei is not distressed, the concept of Qinhai instills him is: I can't help the child, if you want to make a lot of money, the little money of these flowers must not save.

Ningmetale is also an atmosphere. If you listen to Qin Hai, you will be more unhappy.

Several people have been busy from the afternoon, they have been busy late at night, and Zhang Lao San's military dagger and several army of Qinhai are also designed.

Qin Haiji is the theory of ourselves. It has been heat treated for several products, and has tested its mechanical properties, and the face blooms with satisfactory smiles.

"How, Qin Hai, have you been successful?"

Several small friends have been anxious to ask him.

Qinhai nodded: "Success, although there is no ideal state, this knife is better than you have a much harder.

"Can you try?"

Yu Haitao asked.

"What to do with it!

Ningmo took Yu Haitao's head.

It takes so much effort to make things, if it is broken, it can be too traged.

Qin Hai smiled: "We have already measured mechanical performance, there is no need to take it to brick it again?"

"Don't try it, can the Qinhai do something fake?"

Ningmer said.

He took these things, looked at the steel port and color of the knife, and the heart was happy, how can you see enough.

"Fat, don't look, you put these things all, look back, look at Zhang San, see when he said the pretty nephew can come to the county.

Qinhai paided the way in Ningmado.

Ningmei nodded and said: "No problem, I will contact him tomorrow.

However, he doesn't have anything else, so beautiful play, we will have a good play.

Qin Haidao: "You don't think so, we will be so big, but not to give yourself a toy.

These few things are the foundation of our hair, can't sell too cheap.

By the way, if you come, you all don't talk, see that I will talk to him.

"Qin Hai, you can rest assured, we all listen to you."

Several little friends promised to agree, they have become more and more charm of Qin Hai.

Early the next morning, Ning Mo riding a bicycle to a blackmith shop, telling him that the dagger has been done, let him notify the to inspect.

Zhang Lao San quickly agreed, and people in two sides of the blacksmith shop in the blacksmith shop.

At this time, Xiao Dongping, who did not sleep well because of excited and one accounted, also carrying 40 canvas bags in the revolving blade, and boarded the long-distance bus to the provincial city Hongze City.
