Material Empire

"High manganese steel rake blades? Our supply price is $ 8."

Dalton was stupid when he heard the translator recount the price quoted by Zhu Detai.

"8 dollars, how is this possible?" Dalton narrowed his eyes and looked at Zhu Detai unbelievably. "Sir, we mean the price of bulk purchase, not 1 piece, but ... for example, 100,000 sheet."

"The purchase of rake blades is of course in batches. However, if there is such a large quantity of 100,000 pieces, the price can be lowered a little bit. Why, you are interested?" Zhu Detai said.

"Uh ... we don't seem to be talking about the same thing." Dalton was speechless.

From Dalton's point of view, the so-called price of 8 dollars per piece should be the quotation quoted by the North Agricultural Machinery Factory. Selling 3 pieces and 5 pieces does not matter. Selling more will not work. Because Dalton knows how expensive plasma spraying is now, only those companies engaged in aero-engines can afford such equipment. With this equipment for surface treatment of agricultural machinery basic parts, can the price of single chip be lower?

Zhu Detai said something else. Qin Hai promised him that using a thermal sprayer they designed to surface the rake blades would cost less than 3 yuan per piece. Adding to the production cost of the disc rake blade, the final ex-factory price of each piece is less than 10 yuan, which is less than 3 dollars when converted into US dollars. It is already a high profit to quote a price of 8 dollars. If the customer wants 100,000 pieces at a time, he can reduce the price to 7 dollars, or even 6 dollars.

"If I'm not mistaken, you apply titanium nitride coating on the surface of manganese steel rake blades, should you use the plasma spray process?" Dalton asked.

"Plasma_Spray _......" The translator kneeled first. How should the word be translated?

"No, we use the thermal spray process." Qin Hai didn't know where it came from, and gave Dalton a direct answer. Plasma spraying is called "Plasma_Spray" and thermal spraying is called "Thermal_Spray". There is a clear difference between the two.

"Thermal spraying?" Dalton deserves to be the chief engineer of a large company and is quite familiar with the cutting-edge international technology. He frowned, saying, "As far as I know, this technology is still in the exploratory stage. The quality of the coating is very unstable and the cost does not seem to be low."

"If I say that we have broken through all of the key technical issues, which has resulted in a significant cost reduction and quality stability has been resolved. Do you believe it?" Qin Hai asked with a smile.

"Sorry, I'm afraid I can't believe it," Dalton answered honestly.

"Can you provide a piece of evidence?" Hibbs also interjected. He trusted Dalton far more than Qin Hai. Since Dalton said that the technology is still immature, Qin What Hai said was definitely bragging.

Qin Hai picked up a rake from the booth in front of Zhu Detai. Handed it to Dalton, and said, "Sir, you can look at this rake blade. With your professional vision, you should be able to see the quality of the coating. As our director Zhu said just now, we can provide you The quality of a 100,000 piece of rake is the same as this one. The price of each piece does not exceed $ 8. Is this a piece of evidence? "

"Maybe ... as evidence." Hibbs turned to look at Dalton and reluctantly replied.

"But how did you do it?" Dalton's thinking fell into a self-cycle. He couldn't believe that the Chinese would achieve such high achievements in the thermal spraying process, but couldn't deny everything he saw. It is understandable if the Chinese made a few rakes to fill the facade. Now people claim that they can provide 100,000 pieces, and the price is unbelievably cheap, which obviously cannot be explained by using a facade.

Qin Hai said with a smile: "I think. There must be many peers who have such questions. We plan to hold a special report session two days later to introduce you to our achievements in thermal spraying. If you are interested, please pay attention to our upcoming report. "

"Okay, okay, I'll be there to watch then." Dalton nodded.

Obviously, it is impossible to talk about the technical details. Hibbs asked Zhu Detai for two samples of rakes and led Dalton away. Zhu Detai watched the two Frenchmen go far away and turned back to Qin Hai and asked: "Xiao Qin, this thermal spraying technique you developed. Is it really so powerful? I think these two foreign devils are really convinced. "

Qin Hai laughed: "Director Zhu didn't go to see the test results conducted by the organizing committee? Your disc rake blades have already ranked second in the durable life of the rake blade group. The performance is twice that of the manufacturers behind. To be tall, can others be convinced? "

"Second place, who is the first place?" Zhu Detai asked subconsciously.

"It's Lin Xi's director Liu. They said." Qin Hai said.

Lin Xi's director Liu refers to Liu Shuo. The test results of their zirconia ceramic rake blades have reached more than 600 hectares, making them worthy of the first place. Zhu Detai also knew about this matter, because the brother ceramics factory had no experience in making rake blades. When they opened the mold, Qin Hai specially sought Zhu Detai and invited two technicians from the North Agricultural Machinery Factory to do it. guide.

Regarding this powerful competitor, Zhu Detai didn't care. He laughed: "The one that Mr. Liu made is just a toy. No one can take it seriously. When I was on the plane, I heard Mr. Liu said "Their wear resistance of their ceramic rake blades is undisclosed, but the toughness and strength are far from enough to adapt to agricultural production."

"This is indeed the truth. Director Zhu is assured that after the abrasion test is completed, the organizing committee will also conduct a strength test. In addition, it will also take the cost factor into consideration. Qin Hai gave Zhu Detai a peace of mind.

I've been paying attention to durability testing, of course, not just Hibbs alone. As the test results became clearer, the Chinese delegation's booth became lively again. Qin Hai gathered everyone who worked as a translator, gave a simple training, told them some professional knowledge about thermal spraying, and unified the caliber, claiming that there will be a report on thermal spraying in two days.

The tedious and long-lasting durability test is finally over. All the products participating in the test are roughly divided into three echelons according to the different durability life.

The first echelon is four kinds of ceramic basic parts, including ceramic disc rakes provided by the Chinese delegation, and three other ceramic basic parts provided by several western companies. The durable life of these ceramic base parts generally reaches more than 800 hectares, far exceeding the life of metal base parts. However, their shortcomings are also very obvious, that is, they are not tough enough to be used in harsh conditions. In addition, the price of ceramic basic parts is also very high, which has little practical value.

The second echelon is a product using ceramic coatings. What attracts people's attention is that all the products of this echelon come from the Chinese delegation, more precisely, from the thermal sprayer in Qin Hai's hands. Although there is only one thermal spraying equipment, there are more than a dozen products provided by the Chinese delegation, covering all the basic parts of agricultural machinery.

Taking metal as the substrate and coating ceramic material on the surface is equivalent to taking into account the high toughness of metal and the high wear resistance of ceramic, but the cost has not increased significantly. The basis of the Expo Organizing Committee for the evaluation of the basic parts is a number of indicators such as wear resistance, toughness and cost. The cost is calculated based on the supply price promised by the manufacturer, which cannot be faked.

The wear resistance of the Chinese delegation's thermal sprayed basic products is more than double that of other similar products, and there are no obvious disadvantages such as toughness and cost. The comprehensive evaluation of the final evaluation naturally ranks first without any doubt. Already.

As for the third echelon, it is the basic parts produced by traditional technology. Everyone competes in metallurgy and surface treatment of metal materials. The surface treatment products provided by the Chinese delegation with the surfacing process performed well in the same stage as well-known foreign companies, and were basically at the upper and middle level. This achievement was enough to satisfy Cui Hongchun and those business leaders.

The Chinese delegation includes all the first items in the wear resistance test of basic parts!

The news suddenly made a sensation throughout the fair venue.

For those professionals who have been staring at the test process, this result has been foreseen for a long time. If there is any accident, it is that these products with such excellent abrasion resistance have not been expected to be so cheap. For audiences with low professional standards, this news is simply unbelievable, because in the eyes of everyone, China is just a technologically backward developing country. How can there be such terrible results?

"Mr. Minister, how do you feel that the Chinese delegation has won all the individual firsts?"

"I heard that these products use a mysterious process called thermal spraying. Can you introduce the details of this process?"

"Our experts point out that spraying technology is a technology widely used in the military field. Does this technology come from the military?"

"What amazing technology does the Chinese military have ~ www.novelmtl.com ~ Can you tell us ..."

Foreign reporters also know the truth of capturing the thief and capturing the king. They first found Cui Hongchun and surrounded him. A microphone extended so far that they just poked into Cui Hongchun's mouth.

Cui Hongchun was full of breeze and talked:

"We China is committed to the modernization of agriculture. The investment in agricultural science and technology is very considerable, and some excellent results are inevitable. I solemnly declare that these results have nothing to do with military technology. I believe that in the near future In the future, we will show you a variety of outstanding and outstanding results in more fields, so please pay attention. As for the issues related to the thermal spraying process, we will hold a special report meeting in these two days. Let me explain, please be patient. "

Speaking of the last sentence, Cui Hongchun's face showed an undetectable bitter smile:

Nima, I still advertise to Qin Hai! (To be continued. If you like this work, you are welcome to come to the starting point () to vote for recommendations, monthly tickets, your support is my biggest motivation. Mobile phone users please read.)
