Material Empire

1987 Spring International Agricultural Machinery Exhibition is an exhibition co-organized by several departments including the Ministry of Agriculture and the Ministry of Foreign Trade. Officials from various agricultural departments, dealers and technicians of agricultural machinery systems, etc.

In the exhibition, in addition to the publicity and display of various new products and new technologies, economic and trade negotiation activities are also arranged. Units with purchasing intentions can sign supply and sales contracts with exhibitors at the exhibition.

When Qin Hai and Chen Heqian came to the agricultural exhibition hall, they happened to meet several people who looked like officials who were also visiting the scene. Seeing Chen Heqian, one of the officials came over cheerfully, reached out to shake Chen Heqian's hand, and greeted, Professor Chen, you are here too.

Oh, Minister Cui, you also came to visit in person? Chen Heqian hurried forward and greeted the official respectfully. He believed that this official was Cui Hongchun, the deputy minister in charge of agricultural mechanization of the Ministry of Agriculture. Since the production of agricultural machinery often involves technical issues in terms of metal materials, Cui Hongchun and Chen Heqian have dealt with each other several times. In view of Chen Heqian's academic reputation, Cui Hongchun has always respected him.

Is this your student? After exchanging pleasantries with Chen Heqian, Cui Hongchun raised his eyes and saw Qin Hai following behind Chen Heqian, and asked casually.

He is... Chen Heqian didn't know how to introduce Qin Hai for a moment.

Qin Hai smiled and replied, My name is Qin Hai, and I am a student of Teacher Chen. I came here to study with Teacher Chen today.

Yes, I should study hard. Cui Hongchun didn't care about Qin Hai's self-introduction. In his opinion, Qin Hai was just a passer-by, not worthy of being remembered by a leader like him. He only wanted to express his emotions to Chen Heqian:

I don't know if I don't look at it. I was shocked when I saw it. The level of agricultural mechanization technology in developed countries has reached a level that we can only look up to. The technological gap between us and others is really too big.

We are still a developing country. Chen Heqian said the all-purpose excuse, which can be used to deal with all statements about China's backwardness.

Let's go for a walk together? Cui Hongchun gestured with his hand, and said to Chen Heqian, I don't understand some things, so I have to ask you, a great professor, to explain them to me.

Chen Heqian said modestly: Actually, I don't know much. I am engaged in metal materials. At best, I may have a say in the issues of metal materials, but it is also very limited.

After all, Chen Heqian couldn't refuse the minister's offer to walk with you. As a result, the two groups merged into one road, Cui Hongchun and Chen Heqian walked in front, Qin Hai and Cui Hongchun's entourage walked behind, everyone followed the order of the booths, walked slowly, and watched all the way. Agricultural machinery products.

As Chen Heqian said, he doesn't know much about machinery. On the contrary, Cui Hongchun, who has been engaged in agricultural mechanization for a long time, has some experience and constantly introduces the power of tractors, the performance of combine harvesters, etc. to Chen Heqian. Chen Heqian was quite embarrassed, as if he had become a leader, while Cui Hongchun had become a technician.

After passing through several booths, Cui Hongchun pointed forward with a smile and said, Professor Chen, this is your site. Look, this is where plowshares and blades are exhibited. They seem to be all of you who are engaged in metal materials. field of study?

Indeed, I understand some of these things. Chen Heqian replied.

A group of people came to the booth and stopped. Cui Hongchun began to point to the products on the booth and ask the exhibitors questions. In fact, a machine tool like a plowshare is not enough to make a minister stop. Cui Hongchun mainly pretended to have a deep interest in machine tool products in order to reflect the value of Chen Heqian.

This is a three-shared plow used in dry fields. The plow tip is made of three-layer composite steel plate, and the outer layer is made of American SAE1095 fine-grained high-carbon steel... The staff at the booth told Cui Hongchun in not fluent Chinese. The others introduced that this is a Japanese exhibitor, and the staff are also from Japan.

What are the characteristics of this kind of steel? Cui Hongchun turned to Chen Heqian and asked.

This is the field that Chen Heqian is most familiar with. He replied without hesitation: The main feature of this kind of steel is its good wear resistance, which can improve the service life of the plow point. At present, we cannot produce similar steel in our country. Similar wear-resistant steel, so the service life of the plow points produced by ourselves is on average more than one-third shorter than similar foreign products.”

Can you include the development of this steel in your scientific research plan? Cui Hongchun asked.

Chen Heqian smiled awkwardly, and said: This...I'm afraid the Ministry of Agriculture needs to set up a project before we can undertake it. However, I heard that the University of Agricultural Engineering seems to be engaged in research on this kind of steel. I don't know how it is going now. .”

This is the gap. Cui Hongchun sent another sentence of emotion, covering up what he said just now. Chen Heqian wants the Ministry of Agriculture to approve the project, which means that the Ministry of Agriculture needs to pay for it, which makes Cui Hongchun embarrassed. The Ministry of Agriculture has a certain amount of investment in scientific research every year, but there are tens of thousands of projects related to agriculture. The development of this kind of steel seems to be out of the agenda all at once.

This is the rotary tiller blade we represent. Its service life is about 1,200 acres in ordinary clay soil. The material used is JIS_G4401 steel. The staff pointed to several rotary tiller blades on display at the booth and asked Cui Hongchun Introduced.

JIS is the Japanese Industrial Standard, G4401... Chen Heqian hesitated for a moment as he recalled the details of the steel model.

G4401 is a carbon tool steel, also commonly known as SK5 in Japan, the main components include about 0.8% carbon, silicon content not higher than 0.35%, manganese content not higher than 0.5%, phosphorus and sulfur must be lower than 3/10,000 Qin Hai replied for Chen Heqian, for some reason, when he said this, the corners of Qin Hai's mouth turned up slightly, as if there was something ridiculous, but he couldn't laugh out loud.

That's right, it's SK5! Chen Heqian also realized, We can also smelt this kind of steel in our country. Domestically produced rotary tillage blades can be made of this carbon tool steel or spring steel.

However, the quality of the rotary tillage blades we produce is still far inferior to that of Japanese products. At the very least, we cannot produce blades with a service life of 1,200 mu from ordinary clay. Cui Hongchun said. A follower interjected.

Qin Hai turned his head to look at the attendant, and said, Maybe the information you have is not accurate? As far as I know, there are domestic companies that can produce blades that can reach this level of life, and some even exceed this level.

Before the follower could respond, a haughty voice came from behind them: Haha, young man, where did you hear this? In front of us old agricultural machinery, it's a joke for you to say this.

Everyone looked back when they heard the sound, and saw a few people walking behind them, and the one who spoke was the leader. Qin Hai took a closer look and found that he actually knew this person. He was Lou Fuxiang, the director of Pujiang Fenghe Agricultural Machinery Factory.

It was shortly after Ning Zhongying came back to serve as the factory director of Qingfeng Agricultural Machinery Factory. Qin Hai followed Ning Zhongying on a business trip to find the market. The two of them had been to Fenghe Agricultural Machinery Factory. At that time, Lou Fuxiang clearly told Ning Zhongying that the rotary tillers they produced had always only been equipped with rotary tillage blades imported from Japan, and had no interest in domestic blades.

Lou Fuxiang's indifference towards Ning Zhongying and Qin Hai left a deep memory on Qin Hai. However, it was also from Lou Fuxiang that Qin Hai learned about Fukuoka Co., Ltd., and thus opened the window for cooperation with Fukuoka Co., Ltd.

Of course, Lou Fuxiang has no impression of this young man who has had a relationship with him once. Today, he brought a few customers to visit the agricultural machinery exhibition, and overheard Qin Hai saying that domestic rotary tillage blades can also match Japanese blades. The service life can not help but feel absurd. He saw that Qin Hai was very young and he didn't expect to be someone with any background, so he made ridicule.

Director Lou? Someone among Cui Hongchun's entourage recognized Lou Fuxiang and greeted him.

Director Wang! Lou Fuxiang also recognized the other party, and hurried forward with a smile on his face, ready to shake hands with the other party. Compared with the agricultural machinery factory, the Ministry of Agriculture is the absolute superior, and Lou Fuxiang never dares to neglect the people in the Ministry.

Director Wang didn't dare to shake hands with Lou Fuxiang, and there was a minister beside him, so how could he take the lead. He pointed with his hand and said to Lou Fuxiang: Director Lou, let me introduce you. This is our Minister Cui. Minister Cui, this is Director Lou of Fenghe Agricultural Machinery Factory.

Oh, it's Minister Cui! Damn it, I was dazzled just now, and I didn't see that you are here, Minister. What, you came to inspect the agricultural machinery exhibition in person? Lou Fuxiang recognized Cui Hongchun. He and Cui Hongchun had never met directly. I just saw photos of Cui Hongchun in some internal materials. If he had known that Cui Hongchun was present, he would never have dared to refute Qin Hai so presumptuously.

Cui Hongchun looked at Lou Fuxiang, and asked lightly: You just said that what Comrade Xiao Qin said was a joke. Is there any basis for it? How is the quality of domestic rotary tillage blades? Can you introduce it to everyone?

This...hehe, Minister Cui, I just made a slip of the tongue just now. But this...oh, by the way, I think what Comrade Xiaoqin said was a bit too optimistic. The quality of our domestic rotary tillage blades is comparable to that of Japanese products In comparison, it is still slightly inferior. For example, the rotary tillers produced by our factory have always used this brand of rotary tiller blades, and it costs a lot of foreign exchange every year, which is really distressing. If domestic manufacturers can If we can produce blades of the same quality, why should we go far away and import them from Japan? Lou Fuxiang said eloquently.

Qin Hai chuckled, picked up a blade on the booth, and asked Lou Fuxiang: Director Lou, are you saying that your factory has always used blades of this brand because they are better than domestic blades?

Everyone is really awesome. Yesterday, with 538 votes, we have already left behind our opponents who were chasing us.

Thank you for your great love for Orange, there is no repayment, only update.

Today is the last day of August, don't waste the remaining votes, vote for Orange, and see what kind of miracle we can create throughout August.
