"High manganese steel harrows? Our supply price is $8. ”

Hearing the translator relay the price quoted by Zhu Detai, Dalton was stupid at the time.

"$8, how is that possible?" Dalton's eyes widened and he looked at Zhu Detai in disbelief, "Sir, we are talking about the price of bulk purchase, not 1 piece, but ...... For example, 100,000 tablets. ”

"Purchasing rake blades, of course, in batches. However, if there is such a large quantity of 100,000 pieces, the price can be lower, what, do you have the intention? Zhu Detai said.

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

In Dalton's view, the so-called price of $8 a piece should be the price of the Northern Agricultural Machinery Factory as a propaganda offer, and it doesn't matter if you sell three or five pieces, but you can't sell more. Because Dalton knows how expensive plasma spraying is now, only those companies that are engaged in aero engines and the like can afford such equipment. Can the price of a single piece be low when using this equipment to do surface treatment for the basic parts of agricultural machinery?

But what Zhu Detai said was a different story. Qin Hai promised him that the cost of a single piece would not exceed 3 yuan for the surface treatment of the rake sheet with the thermal spraying machine they designed. Coupled with the production cost of the disc harrow piece itself, the final ex-factory price of each piece is less than 10 yuan, which is less than 3 US dollars when converted into US dollars. Quoting at $8 a piece is already a high profit, and if a customer asks for 100,000 pieces in one go, he can completely reduce the price to $7 or even $6.

"If I'm not mistaken, you should use the plasma spraying process to coat the surface of the manganese steel rake with titanium nitride, right?" Dalton asked.

The translator of "Plasma_Spray_Coating......" knelt down first, how to translate this word.

"No, we're using a thermal spray process." Qin Hai didn't know where it came from, and gave Dalton a negative answer bluntly. Plasma spraying is called "Plasma_Spray". Thermal spraying is called "Thermal_Spray", and there is a clear difference between the two.

"Thermal spray?" Dalton, who is worthy of being the chief engineer of a large company, is still quite familiar with the international technological frontier, he frowned, and said: "As far as I know, this technology is still in the exploration stage. The quality of the coating is very unstable, and the cost does not seem to be low. ”

"Would you believe me if I said that we had broken through all of the key technical problems so that the cost was drastically reduced and the quality stability had been solved?" Qin Hai asked with a smile.

"I'm sorry, I'm afraid it's hard to believe." Dalton replied honestly.

"Can you provide one piece of evidence?" Hibbs, who was on the side, also interjected, he trusted Dalton far more than he trusted Qin Hai, since Dalton said that this technology was not yet mature, what Qin Hai said. It's definitely bragging.

Qin Hai picked up a rake sheet from the booth in front of Zhu Detai, handed it to Dalton, and said, "Sir, you can take a look at this rake piece, with your professional eye, you should be able to see the quality of the coating." As our Director Zhu said just now, we can provide you with 100,000 pieces of these rake chips, and the quality is the same as this one. The price does not exceed $8 per piece. Does this count as evidence? ”

"Perhaps...... I guess it can be used as evidence. Hibbs turned his head to look at Dalton and replied reluctantly.

"But. How do you do that? Dalton's mind was stuck in a self-cycle, and he couldn't believe that the Chinese would achieve such a high level of achievement in the thermal spray process, but he couldn't deny what he saw in front of him. It is understandable if the Chinese made several rakes in order to fill the façade. Now people claim to be able to provide 100,000 tablets, and the price is unbelievably cheap, which obviously cannot be explained by window dressing.

Qin Hai smiled and said, "I think." We plan to hold a special report in two days to introduce our achievements in the thermal spraying process, if you are interested, please pay attention to our upcoming report notice. ”

"Okay. Okay, I'll be sure to come and sit in on it then. Dalton nodded.

It was obvious that the technical details could not be discussed any further, and Hibbs asked Zhu Detai for samples of two rake blades, and led Dalton away. Zhu Detai watched the two Frenchmen walk away, turned back to Qin Hai and asked, "Xiao Qin, is this thermal spraying technology you came up with really so powerful?" I think these two foreign devils are really convinced. ”

Qin Hai said with a smile: "Director Zhu didn't go to see the test results of the organizing committee, right?" Your factory's disc rake has been firmly ranked second in the durability of the rake group, and the results are more than twice as high as the latter manufacturers, can people not be convinced? ”

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

"It's Director Liu of Linxi." Qin Hai said.

Director Liu of Linxi refers to Liu Shuo. The test results of the zirconia ceramic rake flakes they produce have reached more than 600 hectares, which is a well-deserved first place. Zhu Detai also knew about this matter, because the brother ceramic factory had no experience in making rake chips at all, and when they opened the mold, Qin Hai specially looked for Zhu Detai and invited two technicians from the North Agricultural Machinery Factory to do guidance.

Zhu Detai didn't care about this tough competitor, he smiled: "The one that Director Liu made is just a toy, and no one will take it seriously." When I was on the plane, I heard Director Liu say that the wear-resistant performance of their ceramic rake pieces was not mentioned, but the toughness and strength were far from enough, and they were not suitable for agricultural production. ”

That's true. Director Zhu can rest assured that after the completion of the wear-resistant test, the organizing committee will also do a strength test, and will also take the cost factor into account. Qin Hai gave Zhu Detai a reassurance.

Hibbs is certainly not the only one who has been paying attention to durability testing. As the test results became clearer, the Chinese delegation's booth began to become lively again. Qin Hai gathered all the people who were in charge of the translation work, did a simple training, told them some professional knowledge about thermal spraying, and unified the caliber, claiming that there would be a report on thermal spraying in two days.

The boring and lengthy durability test is finally over, and all the products participating in the test are roughly divided into three echelons according to the different durability life.

The first echelon is 4 types of ceramic base parts, including ceramic disc harrow pieces provided by the Chinese delegation, and 3 other ceramic base pieces provided by several Western companies. The durability of these ceramic foundations is generally more than 800 hectares, far exceeding the life of metal foundations. However, their flaw is also extremely obvious, that is, they are not tough enough to be used in harsh operating conditions. In addition, the price of ceramic basic parts is also very high, and basically has no practical value.

The second echelon is the use of ceramic coating products, which is interesting to note that all the products of this echelon come from the Chinese delegation, more precisely, from the thermal spraying machine in Qin Hai's hands. Although there is only one thermal spraying equipment, the Chinese delegation provides more than a dozen products, covering all the basic parts of agricultural machinery.

With metal as the matrix and ceramic material coated on the surface, it 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 Organizing Committee of the Expo evaluates the basic parts based on a number of indicators such as wear resistance, toughness and cost, among which the cost is calculated based on the supply price promised by the manufacturer, which cannot be faked.

The wear resistance of the basic parts treated by the Chinese delegation using thermal spraying is more than twice as high as that of other similar products, and there are no obvious disadvantages in toughness and cost.

As for the third echelon, it is the basic parts produced by traditional technology, and we are competing in the metallurgical process and surface treatment process of metal materials. The products provided by the Chinese delegation for surface treatment by surfacing welding process are good in the competition with well-known foreign enterprises, and are basically at the level of the middle and upper reaches, which is enough to satisfy Cui Hongchun and those business leaders.

The Chinese delegation won the first place in all individual items of the wear resistance test of basic parts!

This news immediately caused a sensation in the entire expo venue.

For those professionals who have been staring at the testing process, this result has been foreseen for a long time, and if there is any surprise, it is that these products with such outstanding wear resistance can be so affordable. And for the audience with a low level of professionalism, this news is simply unbelievable, because in everyone's mind, China is just a technologically backward developing country, how can it have such terrible results?

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

"I've heard that these products use a mysterious process called thermal spraying, can you tell us more about this process?"

"Our experts pointed out that spraying technology is a widely used technology in the military field, is your technology from the military?"

"What other surprising technology has been mastered by the Chinese military, can you tell us about it......"

Foreign reporters also know the truth of capturing thieves and capturing kings, they first found Cui Hongchun, surrounded him in the heart, and the microphones stretched so far that they almost poked Cui Hongchun's mouth.

Cui Hongchun was full of spring breeze and talked eloquently:

"China is committed to agricultural modernization, and the investment in agricultural science and technology is very considerable, and it is inevitable that some excellent results will be produced. I solemnly state that these achievements have nothing to do with military technology. I believe that in the near future, we will show you all kinds of outstanding achievements in more fields, so please pay attention. As for the issue of thermal spraying process, we will hold a special report meeting to explain to you in these two days, please be patient. ”

When he said the last sentence, Cui Hongchun showed an imperceptible wry smile on his face:

Nima, Lao Tzu still advertised Qin Hai! (To be continued......)
