CC, the fastest update material empire!

Cui Hongchun is really no way, which will only treat the spingers as a life-saving straw.

To make the superior leaders in the shortest time, the best way is that it is in such an international exhibition.

In this year, China's agricultural machinery technology level, wanted to win in this competition, but it is very difficult, but the cryogenic blade of Qingfeng Factory gave Cui Hongchun.

After all, this kind of blade is capable of being able to enter the Japanese market. Although its service life is just the average level of Japan's similar products, there is such a foundation, then strive to work hard, can you create a miracle? Cui Hongchun is not much confidence in this point, so he needs to ask Chen Heqian and Qin Hai to evaluate.

He has already thought about it, as long as these two think it is possible, he will do our best to satisfy.

It is said that he is going to do it.

This is the case, as long as this political achievement is made, follow-up work is smooth.

"This ... I am afraid some difficulty.

Chen He was frowned and poured a scoop of Cui Hongchun.

"What is difficult, Professor Chen please.

The muscles on the face of Cui Hongchun were slightly twitching, but it was still asked to Chen He Qian.

Chen He Qiandao: "Qingfeng Factory's spiral machine blade, I didn't have to observe it, but listened to Xiao Qin to introduce all of the process.

The Qingfeng Factory can increase the life of the rotating tiller blade to nearly 500 acres, mainly two improvements.

First, they re-smelted the purchased steel, improved the strength of steel; two, they introduced high-frequency reducing process, covering a high wear metal on the cutter head.

"Well, this situation Xiao Qin also introduced me.

Cui Hongchun point.

Chen He has just said: "To further improve the durability of the blade, it is still starting from these two aspects.

One is to further improve the steel formula, and the other is to improve the solder ingredients of the solder.

According to my understanding, Qingfeng Factory has been experiencing some attempts in these two aspects. It is already their extreme.

Of course, there may be some improvements in the future, but it is very difficult to improve.

"Xiao Qin, is this?"

Cui Hongchun turned his head asked Qinhai.

Qin Haidao: "I roughly considering it. In the case of not significantly increased cost, the reform of the blade steel is not large, the solder solder can be further optimized, but this needs to be experimentally.

If everything goes well, we may increase the service life of the blade from the current 1200 mu to 1,500 acres, and reach a high level of similar products in the Japanese market.

but……"

"1500 mu ... This level is completely compared to the international advanced level.

Secretary Li Yang received a cold and coldly.

Cui Hongchun has been pondering this matter these days, and Li Yang, who is a secretary, naturally has to conduct in-depth research on this issue.

According to the information he saw, some farmer manufacturers in Japan, France have been able to increase the service life of the rotary tiller blade to more than 2,000 mu, if only 1,500 mu of the Qin Hai is, it is completely uniform.

Qin Hai said "but"

At this time, it is actually this problem.

He knows about about 1500 acres in the Japanese market, but this is only the products sold in the market, and the highest-end technology owned by the manufacturer is certainly not there.

For this gap, he is also a helpless, because the more high-end walk, the more accurate technical details, this is not the memory fragment that is brought by him from the later generations.

In terms of surfacing technology, he knows how to use this technology, but the formulation of solder can only be constantly exploring.

In this regard, foreign manufacturers have been explored for many years, and the Qingfeng Factory is much bigger than others.

"Li secretary, according to your understanding, the causing machine blade has to reach how much, is it possible to get a better place in the international competition?"

Qin Hai asked Li Yang.

"No less than 2,000 acres.

Li Yang said, he said, he added another sentence: "I am also limited to the information you can get in public channels. I think that if you participate in the game, maybe some manufacturers can take 2500 mu even more lifetime products. .

"This means that we have to double the existing level, this ... almost no possibility.

Chen He said.

He also interested in the difficulty to be high, so as to avoid TUG Hong Chun to apply too much pressure to Qinhai.

"A more double ..."

Qinhai sinking.

"The department can provide you with all necessary conditions.

Cui Hongchun reminded, he also began to fight back the drums. However, since the Qinhai has not explicitly retreat, he still wants to work again.

In his heart, I felt that the Qinhai may be a person who could create a miracle.

"If you want to double, you will not be able to rely on the surfacing process.

Qin Sea said softly.

I heard this, Cui Hongchun has some disappointment, Chen Heqian is a bright eye: "Xiao Qin, you said, do you consider using other processes?"

The surfacing is only one of the methods of improving the tool wear resistance. Since Qin Hai said that it is not suitable for the surfacing process, it means that other processes are still possible.

It is only like Chen Heqian, which is a tacit understanding of Qin Hai, can hear the subtext in Qin Hai.

Qin Hai smiled and opened his mind: "I am a little idea, but it is very immature.

In fact, Qin Hai has already thought of an excellent solution in this moment, but it is not convenient to say it.

Because this program involves a new process of material that is still very tender: thermal spray technology.

The rotary plowing blade is used to cultivated the land, the material TM of the blade is steel, but it is still worn in the soil, still wear, until scrapped.

In order to improve the wear resistance of the blade, it is necessary to attach some high wear resistant materials on the tip.

This type of material is not difficult to find, how difficult is how this material is bonded with the blade.

The surfacing technique used in Qinhai before, is a method of bonding material.

The principle of this method is to mix the wear material to the iron powder into solder, and then apply the solder on the cutter to increase the temperature to melt the solder, thereby fusing with the tool body.

The wear resistant material used in the surfacing technology is much higher than that of ordinary steel, but it is far from achieving the level ideal.

In the field of material, the material wear-resistant performance is not too ceramic. If it is possible to use ceramics to be used as a knife, the wear resistance of the blade will be improved.

The problem is that, although it is known that ceramics can improve wear resistance, it is not found to bind to steel with steel.

The melting point of the ceramics is much higher than the metal, and it cannot be treated with a surfacing process.

In that year, the US-English countries have studied the cutter head of ceramic texture, but it can only be adhered to the tool using high-strength resins.

This adhesive tool head wear-resistant performance is sufficient, but it is conceivable that its impact resistance is extremely weak, after all, the strength and welding of resin bonding are not syndicate.

Thermal spray technology is a different material coating technology. Its principle is also very simple, that is, the spray material such as ceramic particles is heated to a plastic or melting state, then ** to the surface of the pretreated matrix. The spray material is attached to the substrate to form a coating having special properties on the matrix under the premise of the matrix remaining.

It is simple to say that it is equivalent to mounting the material that needs to be attached to a gun, emitting the material to the substrate, which is injected into the base, and forms a coating.

The origin of spraying techniques can be traced back to 1909, a Swiss youth å mutantly the zinc metal å coating technology.

In the next seven or eighty years, spraying technology has been developing and is the first to have extensive applications in the aviation and aerospace.

But at this stage, the spray process is also very complicated, especially the technical requirements of the formation of ceramic coatings are also high, limited to use in high-end equipment manufacturing.

In 1982, the US SKS has developed technology that utilizes high-speed flame gun to realize thermal spraying, and reduces the threshold of thermal spray.

In the following ten years, high-speed flame spraying technology has been developed with great development, thus enabling thermal spray technology to go to the merits and began to enter the production area of ​​ordinary products.

Qin Hai is very understanding of this technical development history. He knows that countries in the world are still in the exploration stage in thermal spraying technology. It is not to use this tall technology on products that do not enter the stream of agriculture.

If he can take the lead in applying this technology, you can use the technical partner, put the competitors far behind.

If you really can stand out in the base match, you can earn a big honor for Cui Hongchun, and for Qin Hai, you can play your own technical brand, thus occupying the thermal spraying process. machine.

The agricultural machine market is actually just a small market. Once the thermal spray process is widely used, its market value is unmetivified.

Such an idea, Qin Hai certainly will not reveal to Cuihongchun in advance, based on Chen Heqian, he doesn't want to explain in advance, knowing that this old gentleman will start to do a vote, will be done in the excitement? The technical essentials of countless hot spray crafts in the Qinhai belly, he didn't want to give such a big fat meat to Chen He Qi.

Cui Hongchun guess the idea of ​​Qin Hai. For this young man, it is a young man who makes money, he is also a bit helpless.

If there is any political requirement in Qinhai, he can take political interests with Qinhai to exchange, but now, Qin Hai is inadvertently, and he has no good way.

"Xiao Qin, do you really have a tool that can participate in the game in three months?"

Cui Hongchun asked.

"There are 80% of grasp.

Qin Hai said low-key.

When he thought of hot spray craftsmanship, he knew that he coded is a number of nine-nine-nine grasps that can get a name on the game, unless the world has changed, foreigners also solved some of the core problems in this process in advance. Thus the same product.
