Material Empire

"Sir, I think you don't have a clear understanding of the current state of global agricultural machinery technology. At the very least, you certainly don't understand the level of basic agricultural machinery in France." A middle-aged white man choked Qin Hai coldly.

Qin Hai smiled and asked, "What's your name, sir?"

"Hibbs, the sales director of France Tolfson Company." The other party replied proudly.

"I'm sorry." Qin Hai bowed slightly to Hibbs to show his courtesy. Qin Hai has really heard of this Thorfson company, and knows that it is a well-known agricultural machinery manufacturer in France, and is especially good at basic parts such as disc harrow blades on lawn mowers.

"Please tell me, what is the current service life of the disc harrow produced by your company?" Qin Hai asked.

"No less than 100 hectares." Hibbs replied.

"We brought three disc harrows of different materials this time. One is about the same quality as your company's product, which is about 100 hectares; It has not been tested to the limit of its use..." Qin Hai said, he always had a smile on his face, but what he said made Hibbs almost violently go away.

"Mr. Qin, I don't think your joke is very humorous. Everyone here is an industry insider. They will only feel bored with your clumsy joke." Hibbs said with a dark face. He was originally here to watch the fun, and he neither liked nor disliked the Chinese delegation. But this time, he felt a little angry with the Chinese in front of him.

What Qin Hai wants is the feeling of the other party. If the other party is not strongly stimulated, how can he spread the reputation 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, why do you think I'm joking?"

"There is no material that can achieve a service life of 300 hectares. The wear resistance of metal determines that 300 hectares is an impossible goal. If you can use ceramics as a rake material, I can still believe it. However, the rake blade It needs a sharpening edge, it's not a plowshare," Hibbs said.

Plowshares, harrows and other basic parts are directly used for plowing the field, and they need to rub against the soil for a long time during operation. The life of these basic parts mainly depends on the wear resistance of the material. In order to improve wear resistance, some companies are already trying to use ceramics as the base material, which is not news.

The mower blades produced by Tolfson Company have to undertake the two tasks of mowing and loosening the soil at the same time. In order to cut tough grass stems, the blades of the blades must be as sharp as ordinary knives. This is The concept of "sharpening" as Hibbs said. Because it involves cutting the blade, this kind of rake blade cannot be made of ceramics. With the current ceramic technology, if the cutting edge is cut very thin, it will basically break with a single knock.

Except for this kind of rake, other basic parts can barely be made of ceramics. For example, the rotary cultivator blade produced by Qingfeng Factory is called a blade in name, but in fact the blade has a certain thickness, more like a thin steel plate. If ceramics are used to make this blade, the cutter head can guarantee a certain strength.

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

Of course, Qin Hai knew that what Hibbs said was true. With the current technology of all countries in the world, it is indeed impossible to manufacture a rake 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 he can create what others can't. If there is no such thing against the sky, how dare he let Cui Hongchun bring a delegation to Brazil?

"Mr. Hibbs, there is an old Chinese saying that hearing is believing, seeing is believing. How about our products, we can test them. I heard that this expo has specially arranged a competition for the durability of basic components. 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? In fact, the competition has already started. If you are interested, you can sign up for the competition at any time. Everything is free." The people next to them said one after another. It's not a big deal to watch the excitement, they don't care who will lose face, Qin Hai or Hibbs, they just want to watch a free show.

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 what everyone is concerned about, so the organizing committee simply started the test in advance, and all exhibitors who arrive in Sao Paulo can first prepare themselves The samples of the basic parts are sent to the organizing committee, and they will be tested as soon as they arrive, and the results will be announced as soon as they are available.

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

"So fast..." Everyone's first reaction was the same. Although they came here for the competition, they were inexplicably nervous when they heard that samples could be sent for testing now.

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

This time, more than a dozen domestic agricultural machinery companies participated in the exhibition, each producing different basic parts. For example, Qingfeng Factory produces traditional rotary tillage blades, while disc harrow blades are produced by Northern Agricultural Machinery Factory.

Although the manufacturers of the basic parts are different, the material processing techniques are all produced by Qin Hai. The treatment processes used by each enterprise include two, one is the high-frequency surfacing technology transferred by Qingfeng Factory, and the other is the thermal spraying technology just researched by Li Linguang and Yue Kun. Due to the lack of thermal spraying equipment, each enterprise just sent some products to Qingfeng factory, and Qingfeng factory did thermal spraying treatment on its behalf. It will take some time to promote the thermal spraying process on a large scale.

Both surfacing welding technology and thermal spraying technology were developed by Qin Hai. How effective is it and whether it can be invincible in the process of competing with international giants? Only Qin Hai can answer this question.

"Before going abroad, haven't we already done the test? Our craftsmanship can stand the test." Qin Hai looked at everyone's burning eyes, and felt a little helpless. They were all a group of prominent leaders. He also pointed to him, a 20-year-old young man, as the backbone, which is really embarrassing to say.

"Well, if you don't enter the tiger's den, you won't catch tiger cubs. Now that you're here, the ugly daughter-in-law has to see her in-laws too. Everyone, prepare all the samples you brought, Chang Song, Xiao Cheng, and you, accompany Xiao Qin, to bring Send the samples to the organizing committee." Cui Hongchun gritted his teeth and made up his mind.

Watching the Chinese take out test samples from all kinds of shabby packing boxes and pile them on small carts, the foreigners who watched were all agitated. From a common sense point of view, they do not believe that these products produced by the Chinese are of any testing value, but the big words released by Qin Hai just now make them a little suspicious. Something that shocked the world.

Liu Shuo and Huang Yanling also opened the boxes they brought, took out two items wrapped in linen, and handed them to Qin Hai. Qin Hai laughed, pointed to the linen bag, and said to Hibbs: "Mr. Hibbs, the product I'm talking about has not been tested for its limit life, here it is, and I will send it to the organizing committee soon. Are you interested in taking a look?"

"Of course, I also really want to know what kind of technology you have invented to make products with no limit lifespan." Hibbs replied with a somewhat mocking tone.

Qin Hai, Wang Changsong, and Cheng Feng pushed their carts to the site where the organizing committee tested the basic components. A group of representatives of foreign companies followed behind, wanting to see what was going on. This strange small team immediately attracted the attention of other people. When those people came forward to inquire, they realized that it was the Chinese who made bold claims, claiming to be able to produce products that reached the technology of the 1990s. Everyone was 70% disdainful and 300% suspicious, and those who had nothing to do at the moment also followed the ranks of people who went to watch the fun.

"These are the three types of disc harrows that we are going to participate in the competition." Qin Hai came to the test site and began to submit test samples to the staff. He handed over three different rakes, and the last one was taken out of the linen bag Liu Shuo gave him.

"This rake blade should be made of carbon steel, and the cutting edge has undergone a surfacing process." Hibbs stood aside, softly commenting on the first rake blade Qin Hai took out.

"Mr. Hibbs is indeed an expert." Qin Hai said with a smile. The surfacing welding process is the most commonly used process for processing the cutting edge of basic parts. All companies are using it. The only difference lies in the different surfacing welding materials. It's no surprise that Hibbs recognized the craft.

"This rake is also made of carbon steel, and the surface treatment...seems a bit strange..." Hibbs was a little confused when he saw the second rake. This rake was treated by Qin Hai with a thermal spraying process. The surface of the cutting edge is covered with a thin layer of titanium nitride particles, which feels slightly harsh to the touch. Since there was no trace of solder in sight, Hibbs knew that this was definitely not a surfacing process.

"Hehe, this is a new technology we developed, and it is still kept secret." Qin Hai smiled and handed the rake to the staff of the organizing committee.

"This... hiss, it's actually made of ceramics!" Seeing the rake that was taken out of the sackcloth bag, not only Hibbs, but everyone present widened their eyes. The color of this rake is off-white, without the texture of metal at all, and it can be seen that it is of ceramic texture at a glance. What makes everyone feel incredible is that it completely breaks the conclusion that ceramics cannot be sharpened. Its edge looks as thin as a piece of paper, almost reaching the sharpness of the edge of a metal blade.
