"1987 Spring International Agricultural Machinery Exhibition" is an exhibition jointly organized by the Ministry of Agriculture and the Ministry of Foreign Trade and other departments, and the exhibitors are internationally renowned agricultural machinery manufacturers and dealers, and the visitors to the exhibition include officials from various agricultural departments, distributors and technicians of agricultural machinery systems, etc.

At the exhibition, in addition to the publicity and display of various new products and new technologies, economic and trade negotiation activities are also arranged, and units with purchasing intentions can sign supply and marketing 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 and were also visiting the scene. Seeing Chen Heqian, one of the officials came over happily, took the initiative to reach out and shake hands with Chen Heqian, and greeted him: "Professor Chen, you are here too." ”

"Oh, Minister Cui, you also came to visit in person?" Chen Heqian hurriedly stepped forward and greeted the official respectfully. He believes that this official is the vice minister in charge of agricultural mechanization in the Ministry of Agriculture, named Cui Hongchun. Because the production of agricultural machinery often involves technical problems in metal materials, Cui Hongchun and Chen Heqian have dealt with several times. Given Chen Heqian's academic prestige, Cui Hongchun has always respected him.

"Is this your student?" After Cui Hongchun exchanged a word of greeting with Chen Heqian, he raised his eyes and saw Qin Hai following behind Chen Heqian, so he asked casually.

"He's ......" Chen Heqian didn't know how to introduce Qin Hai for a while.

Qin Hai replied with a smile: "My name is Qin Hai, I am a student of Teacher Chen, and I came to study with Teacher Chen today. ”

"yes, it's time to learn hard." Cui Hongchun didn't care about Qin Hai's self-introduction, in his opinion, Qin Hai was just a passerby's character, not worthy of a leader like him to remember. He only cared about expressing his feelings to Chen Heqian:

"I don't know if I don't see it, and I'm shocked when I see it. The technical level of agricultural mechanization in developed countries has reached a point where we can only look up, and the technological gap between us and others is too big. ”

"We're still a developing country." Chen Heqian said an all-powerful excuse that could be used to deal with a statement about China's backwardness.

"Let's go for a walk?" Cui Hongchun gestured with his hand and said to Chen Heqian. "There are some things I can't understand, 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 little say in the problems of metal materials, but it is also very limited." ”

After all, the minister offered to go with you, and of course Chen Heqian couldn't refuse. So, these two passers-by merged all the way, with Cui Hongchun and Chen Heqian walking in front. Qin Hai and Cui Hongchun's entourage walked behind, and everyone walked slowly along the order of the booth, watching all kinds of agricultural machinery products displayed by various manufacturers all the way.

As Chen Heqian said, he didn't know much about machinery, but Cui Hongchun, who had been engaged in agricultural mechanization for a long time, had some experience, and constantly introduced the power of tractors, the performance of combine harvesters, and so on. made Chen Heqian quite embarrassed, as if he had become a leader. Cui Hongchun, on the other hand, became a technician.

Walking past a few booths, Cui Hongchun pointed forward with a smile and said, "Professor Chen, it's your place here, you see, this is a display of ploughshares and blades." This seems to be the field of research for you people who are engaged in metal materials, right? ”

"Yes, I know a little bit about these things." Chen Heqian replied.

The group walked up to the booth and stopped, and Cui Hongchun began to point to the products on the booth and ask questions to the exhibitors. Actually, such a machine as a ploughshare. It is not enough for a minister to stop, Cui Hongchun is mainly to reflect the value of Chen Heqian, so he pretends to have a deep interest in machine products.

"This is a three-share plough used in the dry field, the tip of the plough is made of three-layer composite steel plates, and the outer layer is made of American SAE1095 fine-grained high-carbon steel ......" The staff at the booth introduced to Cui Hongchun and others in Chinese, who were not fluent in Chinese, and this was a Japanese exhibitor, and the staff were also from Japan.

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

This can be asked about the field that Chen Heqian is most familiar with, and he replied without thinking: "The main feature of this steel is that it has good wear resistance, which can improve the service life of the plough tip. At present, we are not able to produce similar wear-resistant steel in China, so the service life of our own plough tip is on average more than one-third shorter than that of 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 we need a project from the Ministry of Agriculture before we can take it. However, I heard that the University of Agriculture and Engineering seems to be engaged in the research of this kind of steel, but I don't know how it is progressing now. ”

"That's the gap." Cui Hongchun let out another sentence of indescribable emotion, covering up what he said just now. Chen Heqian wants the Ministry of Agriculture to set up a project, which means that the Ministry of Agriculture needs to pay for it, which makes Cui Hongchun embarrassed. The Ministry of Agriculture invests a certain amount of money in scientific research every year, but there are thousands of projects related to agriculture, and the development of this steel seems to be on the agenda all of a sudden.

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

"JIS is the Japanese industrial standard, G4401 is ......" Chen Heqian recalled the specific details of this steel model in his mind, and hesitated for a while.

"G4401 is a carbon tool steel, also commonly known as SK5 in Japan, the main components include about 0.8% carbon, silicon content is not higher than 0.35%, manganese content is not higher than 0.5%, phosphorus and sulfur must be less than 3 parts per thousand." Qin Hai replied for Chen Heqian, for some reason, when he said this, the corners of Qin Hai's mouth were slightly upward, as if there was something ridiculous, but it was inconvenient to laugh out loud.

"Yes, yes, it's SK5!" Chen Heqian also reacted, "This kind of steel." We can also smelt in China. The domestically produced rotary tillage blades have this carbon tool steel, and there are also spring steels. ”

"However, the quality of our own rotary tillage blades is still much worse than that of Japanese products. At the very least, the service life of ordinary clay reaches 1200 acres of blades. We can't produce it anyway. One of Cui Hongchun's entourage interjected.

Qin Hai turned his head to look at the entourage and said, "The situation you have may not be accurate, right?" As far as I know, there are also domestic enterprises that are able to produce blades that have reached this level of life, and some even exceed this level. ”

Without waiting for the attendant to respond, behind them, an arrogant voice came: "Haha, little young man, where did you hear this?" In front of us old agricultural machinery, you say this is a joke. ”

When they heard this, they looked back. I saw a few people walking behind them, and it was the leader who spoke. 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 not long after Ning Zhongying had just returned to serve as the director of Qingfeng Agricultural Machinery Factory, Qin Hai went on a business trip with Ning Zhongying to find the market, and the two of them went to Fenghe Agricultural Machinery Factory. At that time, Lou Fuxiang clearly told Sù Ning Zhongying. The rotary tiller they produce has always only been equipped with rotary tiller blades imported from Japan, and they have no interest in domestic blades.

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

Lou Fuxiang has no impression of this young man who has had a relationship with him, he came to visit the agricultural machinery exhibition with several customers today, and inadvertently heard Qin Hai say that domestic rotary tillage blades can also reach the service life of Japanese blades. I can't help but feel ridiculous. He saw that Qin Hai was very young, and he didn't expect that he was a person with a background, so he ridiculed him.

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

"Director Wang!" Lou Fuxiang also recognized the other party, and hurriedly stepped forward with a smile on his face. Prepare to shake hands with the other person. Compared with the agricultural machinery factory, the Ministry of Agriculture is the absolute top boss, and Lou Fuxiang does not dare to slack off the people in the ministry.

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

"Oops, it's Minister Cui! Damn, damn it, I was dazzled just now, I didn't see you here, Minister. Why, did you come to inspect the agricultural machinery exhibition in person? Only then did Lou Fuxiang recognize Cui Hongchun, he and Cui Hongchun had not directly met, but had only seen Cui Hongchun's photos in some internal materials. Knowing that Cui Hongchun was present, he would never dare to refute Qin Hai so presumptuously.

Cui Hongchun looked at Lou Fuxiang and asked lightly: "You just said that Comrade Xiao Qin's words were a joke, is there any basis?" What is the quality of domestic rotary tillage blades, can you introduce it to you. ”

"This ...... Hehe, Minister Cui, I just lost my words for a while. But this ...... Oh, by the way, what Comrade Xiao Qin said, I think it's a bit too optimistic. The quality of our domestic rotary tillage blades is still slightly inferior to that of Japanese products. For example, the rotary tiller produced by our factory has been using this brand of rotary tiller blade, which costs a lot of foreign exchange every year, which is really distressing. If domestic manufacturers can produce blades of the same quality, why should we go to Japan to import them? Lou Fuxiang said vigorously.

Qin Hai smiled, picked up a blade on the booth, and asked Lou Fuxiang: "Director Lou, you mean that your factory has been using this brand of blades because it has better quality than domestic blades?" (To be continued......)
