"Sir, I don't think you know enough about the technical status of the global agricultural machinery, at least you definitely don't know what the level of agricultural machinery basic parts in France is." A middle-aged white man coldly choked Qin Hai.

Qin Hai smiled and asked, "What do you call Mr." ”

Hibbs, Sales Director at Tolfsen in France. The other party replied arrogantly.

"Disrespectful." Qin Hai bowed slightly to Hibbs as a sign of politeness. Qin Hai had really heard of this Tolfsen company and knew that it was a well-known manufacturer of agricultural machinery in France, especially the basic parts such as disc rakes on lawn mowers.

"Excuse me, what is the current service life of the disc rake blades produced by your company?" Qin Hai asked.

"Not less than 100 hectares." Hibbs replied.

"We brought three different materials of disc rakes this time, one is about the same as the quality of your company's products, which is also about 100 hectares; One can reach at least 300 hectares; There is another ...... We're sorry, but we haven't tested the limits of its use......" Qin Hai said, with a smile on his face all the time, but what he said made Hibbs almost angry.

"Mr. Qin, I don't think your joke is humorous, everyone present is in the industry, and they will only be bored with your clumsy joke." Hibbs said with a dark face. Originally, he had come to see the excitement, and he had neither any good feelings nor any bad feelings for the Chinese delegation. But this time, he already had some angry feelings about the Chinese in front of him.

What Qin Hai wants is the other party's feeling, if the other party is not strongly stimulated, how can he spread the fame of these products in his hands? He looked at Hibbs, pretended to be innocent, shrugged his shoulders and said, "I'm telling the truth, Mr. Hibbs. Where do you think I'm joking? ”

"No material can achieve a service life of 300 hectares, and the wear strength of the metal determines that 300 hectares is an impossible goal. If you can use ceramic as a rake material, I can still believe it, but the rake is edged, it is not a ploughshare. Hibbs said.

Ploughshares, harrows and other basic parts. They are all used directly to plough the field, and the operation requires long-term friction with the soil, and the life of these basic parts mainly depends on the wear resistance of the material. In order to improve wear resistance, it is not news that some companies are already experimenting with ceramics as a base material.

In order to be able to cut tough grass stems, the edge of the rake blade must be as sharp as an ordinary knife, which is the concept of "cutting the edge" according to Hibbs. Because it involves cutting edges. Therefore, this kind of rake piece cannot be made of ceramics, and with the current ceramic technology, if the cutting edge is very thin, it will basically be broken as soon as it is knocked out.

With the exception of these rake blades, the rest of the basic parts can barely be manufactured using ceramic. For example, the rotary tiller blade produced by Qingfeng Factory is nominally called a blade, but in fact, the knife edge has a certain thickness, which is more like a thin steel plate. If you use ceramics to make this kind of blade. The cutter head can ensure a certain strength.

Although Hibbs is engaged in sales, he still has a very good understanding of the performance and technology of the product. In a few words, he rejected all possibilities. Without these possibilities, Qin Hai's words could only be baseless bragging.

Of course, Qin Hai knew that what Hibbs said was true, with the current technology of countries around the world, it was indeed impossible to manufacture rake sheets with a durable life of more than 300 hectares. But the problem is that Qin Hai's own technology is already ahead of this world, and others can't make it. But he can make it. If there was no such unnatural goods, how dare he let Cui Hongchun come to Brazil with a delegation?

"Mr. Hibbs, there is an old Chinese saying that hearing is false, seeing is believing. How about our products. You can test it out. I heard that this expo has specially arranged a durability competition for basic parts, and I don't know if there are any requirements for registration. Qin Hai said leisurely.

"Mr. Qin, is the Chinese delegation also planning to participate in this competition? Actually, now that the competition has begun, if you are interested, you can sign up for the competition at any time, and it is free. The people next to him said one after another, this is not a big deal to watch the excitement, they don't care who Qin Hai or Hibs will lose face, everyone just wants to watch a free play.

It turns out that the test of the durability of the basic parts is a very time-consuming thing, and the results of the competition are of concern to everyone, so the organizing committee simply started the test in advance, and all exhibitors who arrived in São Paulo can first send the samples of the basic parts they are ready to participate in the competition to the organizing committee, and the results will be announced as soon as they are available.

Hearing that there was such a policy, Qin Hai didn't care about talking to everyone, he returned to his own people and informed everyone about the situation.

"So fast......" everyone's first reaction was like this, although they came here for the competition, but when they heard that they could send samples for testing now, everyone was still inexplicably nervous.

"Xiao Qin, are you sure?" Cui Hongchun asked Qin Hai seriously, and everyone also turned their eyes to Qin Hai.

This time, there are more than a dozen domestic agricultural machinery enterprises that come to the exhibition, which produce different basic parts. For example, the Qingfeng factory produces the traditional product rotary tillage blade, and the disc harrow blade is produced by the North Agricultural Machinery Factory.

Although the manufacturers of basic parts are different, the material treatment process is all from Qin Hai's hands. The treatment processes used by various companies include two treatments, one is the high-frequency surfacing technology transferred by the Blue Point plant, and the other is the thermal spraying technology that Li Linguang and Yue Kun have just developed. Due to the lack of thermal spraying equipment, the enterprises only sent some products to the Qingfeng factory, and the Qingfeng factory did the thermal spraying treatment on behalf of the company. It will take some time for the thermal spray process to be rolled out on a large scale.

The surfacing technology and thermal spraying technology are all made by Qin Hai, what is the effect, and whether it can be invincible in the process of competing with international giants on the same stage, this question can only be answered by Qin Hai.

"Didn't we already do the test before we went abroad? Our craftsmanship is tested. Qin Hai looked at everyone's burning eyes, and felt a little helpless, they were all leaders with heads and faces, and they actually pointed to him, a 20-year-old young man, as the backbone, which was really embarrassing.

"Okay, if you don't go into the tiger's den, you can get the tiger. Since she is here, the ugly daughter-in-law always has to see her in-laws. Everyone prepare the samples you brought, Chang Song, Xiao Cheng, you accompany Xiao Qin and send the samples to the organizing committee. Cui Hongchun gritted his teeth and made up his mind.

Watching the Chinese take out samples for testing from various rudimentary packing boxes and pile them on small carts, the onlookers became restless. From the perspective of common sense, they do not believe that these products taken out by the Chinese have any test value, but the big words released by Qin Hai just now made them a little suspicious, could it be that the Chinese really engaged in some black technology and came up with something enough to shock the world.

Liu Shuo and Huang Yanling also opened the box they brought, took out two items wrapped in linen cloth from inside, and handed them to Qin Hai. Qin Hai smiled, pointed to the burlap bag, and said to Hibbs: "Mr. Hibbs, the products I said have not yet tested the ultimate lifespan, right here, I will send it to the organizing committee soon, are you interested in taking a look?" ”

"Of course, I'd love to know what technology you've invented to create products that don't have an unlimited lifespan." Hibbs replied in a somewhat mocking tone.

Qin Hai, Wang Changsong, and Cheng Feng pushed the cart to the site where the organizing committee tested the basic parts, and the representatives of foreign companies all followed behind, wanting to see what was going on. This strange little team immediately attracted the attention of others, who came forward to inquire and learned that it was the Chinese who made a bold statement, claiming to be able to come up with products that reached the technology of the 90s. Everyone was full of seven points of disdain and three points of suspicion, and those who were temporarily fine at hand also followed up to see the lively procession.

"Here are the three disc harrows that we are ready to race." Qin Hai came to the test site and began to submit test samples to the staff. He handed over three different rakes, the last one taken from the sack bag that Liu Shuo had given him.

"This rake should be made of carbon steel as the matrix, and the cutting edge has been treated by the surfacing process." Hibbs stood aside and whispered on the first rake piece that Qin Hai had taken out.

"Mr. Hibbs is indeed an expert." Qin Hai said with a smile, the surfacing process is the most commonly used process for dealing with the cutting edge of basic parts, and it is used by various companies, and the difference is only in the difference in surfacing materials. It's no surprise that Hibbs was able to recognize the craft.

"This rake is also a carbon steel matrix, with a surface treatment...... It seems strange...... "When he saw the second rake, Hibbs was already a little confused. This rake blade was treated by Qin Hai with a thermal spraying process, and the surface of the cutting edge was covered with a thin layer of titanium nitride particles, which felt a slight awkward feeling to the touch. Since there was no trace of solder in sight, Hibbs knew that it was definitely not processed with the hardfacing process.

"Hehe, this is a new process we have developed, and it is still under wraps." Qin Hai smiled and handed the rake to the staff of the organizing committee.

"This ...... Sizzle, it's actually ceramic! When he saw the rake piece that he had taken out of the burlap bag, not only Hibbs, but everyone present had their eyes widened. The color of this rake piece is grayish-white, and there is no metallic texture at all, and you can tell at a glance that it is the texture of ceramic. To everyone's incredibleness, it completely breaks the conclusion that ceramics cannot be bladed, and its edge looks as thin as a piece of paper, almost reaching the sharpness of the edge of a metal blade.
