Zhang Yiming couldn't help but laugh dumbly, at present, the gap between China and the international advanced level in material science is still relatively large, such as the largest use of marine steel plates, which seems to be the simplest, and the country still has to import a large number of them. ▲∴

Ordinary marine steel plate itself is not too difficult, but the shipbuilding industry has its particularity, marine steel plate is used in the thick steel plate, at present, the number of rolling mills of our medium and heavy steel plate is still relatively small, and most of them are rolling mills below 2800, and the real international advanced level of medium and heavy steel plate rolling mills are only a few such as Hucheng Iron and Steel, Sanjiang Iron and Steel.

In addition, because the hull is built in sections, that is, the steel plate is first tailored welded into sections, and then the sections are welded into the total section, and the hull of this length is welded to a section of the hull and then closed the welded ring seam. Generally speaking, the fewer welds, the better, so there are two trends in the demand for marine steel plates, one is that the size of a single steel plate is getting larger and larger, longer and wider, and the other is that the size customization requirements are getting higher and higher, and the customization standard is high, which means that the utilization rate of steel plates is relatively high.

At present, there are very few domestic steel mills that can provide customized steel plates, and most of them are still in the standard of producing 8m, 10m and 12m, and now the segmented manufacturing has begun to use 24m, and the segmented weight is as high as six or seven hundred tons.

The gap in hull materials is mainly in the processing, through the addition of a large plate rolling mill, the addition of online width measurement, thickness measurement, length measurement, flaw detection and other automatic testing, as well as cold and hot straightening, automatic marking and other technologies, the quality of domestic ship plates will be greatly improved in the future.

However, some special materials, not only the gap is greater, but it is also not easy to catch up. Because it is different from ordinary marine steel plate in terms of technology and manufacturing technology, the formula, heat treatment and production process of special materials are all new, and a subtle difference may affect the performance of the material. This can only be explored by relying on a large number of real yàn, and a large number of real yàn means a large amount of manpower, resources and time investment.

At least as far as Zhang Yiming knows, domestic research in this area is not very strong, and the progress made is very limited. At present, the domestic shipbuilding industry has indeed occupied a place in the world shipbuilding market, but many materials and important accessories need to be imported, such as the main engine.

In simple terms. At present, many domestic shipyards can only build hulls on the exported ships, and there is still a big gap with the international advanced level.

If Haizhou Shipbuilding Industry Group can really solve the material problem of the marine main engine, although this does not mean that Haizhou Shipbuilding Industry Group can build an advanced main engine, at least the most basic problem has been solved.

The current situation in China is that many things can be made theoretically, even in the real room, but because of material problems, many good designs cannot be used in products, or the designed products cannot be mass-produced.

And this phenomenon is not limited to the shipbuilding industry. It is also widely found in other fields, and it has become the main bottleneck restricting our industrial upgrading, such as in the field of aviation, such problems are also very prominent.

Now Bao Feiyang actually said that they have made an important breakthrough in the host material, which is a joke in Zhang Yiming's opinion. The problems that have not been solved by so many material research institutes and ship research institutes in the country can be solved by Haizhou Shipbuilding Industry Group, a company that has just been established and can only manufacture inland boats in the past. There is simply no possibility.

Although Zhang Yiming did not agree to Bao Feiyang's invitation, he still had a good impression of Bao Feiyang. Now this favor has almost disappeared all at once, and what he hates most are those who like to tell empty words, lies and clichés, and now it seems that Bao Feiyang is the same as other officials, and he is younger and less serious.

Zhang Yiming didn't even bother to say anything questioning, just smiled coldly.

Bao Feiyang saw Zhang Yiming's expression in his eyes. Knowing that he didn't believe it, he continued: "Of course, if this technology is to be said to be made by our Haizhou Shipbuilding Industry Group ourselves, Mr. Zhang, you definitely don't believe it." Actually, this is our partner, to be exact. It is Fangxia Special Ceramics Co., Ltd. to get out, they developed a composite ceramic material, excellent strength and wear resistance, can be used to manufacture the main bearing, greatly improve the strength and wear resistance of the host bearing, Fangxia special ceramics has planned to build a factory in Haizhou Lingang Economic Development Zone, specializing in the production of this ceramic composite material, and solve the material problem of the main shaft for us. ”

"Fangxia Ceramics Group?" Zhang Yiming Huo turned his head to look at Bao Feiyang, Fangxia ceramics was established for a short time, at the beginning of ceramic additives and high-grade civil ceramics started, and gradually realized large-scale operation, at present, Fangxia ceramics group has branches in many places at home and abroad, and has played an important role in helping the local industry to achieve industrial development.

Of course, Zhang Yiming knows that Fangxia Ceramics Group is not because of the status and popularity of Fangxia Ceramics Group in the field of civil ceramics, but because of the achievements of Fangxia Ceramics Group in special ceramic materials, and they have launched a variety of structural ceramics, functional ceramics and tool ceramics.

Ceramics is a material that ordinary people have in the impression of dishes and porcelain, although it is beautiful, but it is fragile and impractical. However, in fact, ceramic materials are widely used in industry, such as ceramics have the advantages of high hardness, corrosion resistance, wear resistance, etc., so they are very widely used.

The advantages of special ceramic materials are more prominent, and overcome the shortcomings of the relatively brittle nature of ceramic materials, and are widely used in tools, molds, fire resistance and high temperature resistance, sealing and other fields.

There are not many types of special ceramics launched by Fangxia Ceramics Group, but they have launched several products, whose performance is at the forefront of the industry, such as a nano ceramic coating they launched, which has very good high temperature resistance, and can be used for surface spraying of a variety of substrates to improve the high temperature resistance of the material, and its high-end products can be used inside the engine, which greatly exceeds the performance of existing products.

In addition to several national-level research institutes, if there is anyone else in China who can make achievements in new materials, especially ceramic materials, only Fangxia Ceramics Group can make Zhang Yiming believe. And Zhang Yiming also learned that Fangxia Ceramics Group also seems to produce a special ceramic coating, which can greatly improve the performance of domestic aircraft engines.

Hearing that Fangxia Special Ceramics was going to build a factory in Haizhou, Zhang Yiming couldn't help but feel very shocked: "You mean that Fangxia Special Ceramics has made a new breakthrough in high-strength and wear-resistant ceramic materials, and wants to invest in Haizhou and cooperate with your Haizhou Shipbuilding Industry Group." Designing and producing efficient marine engines? ”

Bao Feiyang nodded and said: "Yes, the first workshop built by Haizhou Shipbuilding Industry Group will be the production workshop of this new marine engine, and we will build this as our core competitiveness to design and manufacture our own marine main engine." ”

"No, even if you have this kind of material with superior performance, you don't have the ability to design and manufacture a high-performance marine main engine!" Zhang Yiming was excited. New questions were raised. The design and manufacture of marine main engine is also a complex system engineering, at present, the domestic marine low-speed diesel engine is basically imported or introduced into the license technology of foreign diesel engines, more than 70 percent of the medium-speed diesel engines used in the construction of ocean-going ships in China are imported original engines, and the remaining 30 percent are almost all products manufactured by the introduction of foreign license technology, even so, the localization rate of this part can only reach 70 percent and 80 percent, and key spare parts still need to be imported.

Zhang Yiming is not specialized in the research of marine main engines, he is engaged in comprehensive shipbuilding engineering, but he also pays more attention to the main engine. At present, the design of the main engine of marine ships in China is also very weak, and there is almost no design capacity for the main engine of large ocean-going ships, and the existing design capacity is mainly concentrated in the main engine for offshore and inland ships.

Haizhou Shipbuilding Industry Group focuses on the development of marine main engines, which Zhang Yiming appreciates very much, but he does not think that Haizhou Shipbuilding Industry Group has the ability to complete the design and manufacture of marine main engines alone. Even if Bao Feiyang is proud of the advantages of materials, it is also obtained by Guò and Fangxia Ceramics.

In fact, Zhang Yiming is also very strange, I don't know why Fangxia Ceramics Group chose Haizhou Shipbuilding Industry Group as the object of cooperation, there are many more powerful shipyards and OEMs in China. Haizhou Shipbuilding Industry Group should not be ranked at all.

Bao Feiyang smiled and said, "Mr. Zhang, this project has not yet been made public. However, it has basically been decided that Huaxia Shipbuilding Corporation, 177 Institute, Fangxia Special Materials, and Haizhou Shipbuilding Industry Group Industrial Group will jointly invest in the construction of marine main engine projects in Haizhou Lingang Economic Development Zone. ”

"One hundred and seventy-seven?" Zhang Yiming was stunned again, the 177 Research Institute is the same as the Whampoa Military Academy in the shipbuilding industry, it is a national team, and the 177 Institute has a military background. Even a madman like Zhang Yiming is full of admiration for the 177th Institute.

"Mr. Bao, are you saying that the 177th Institute will also participate in this project? Is there such an intention, or has it already been decided? Zhang Yiming asked, still feeling incredulous. He even felt that Bao Feiyang was talking nonsense. It is likely that it was just the beginning of contact, and even wishful thinking on the part of Haizhou, and as a result, Bao Feiyang made a lot of publicity.

If Fangxia Ceramics cooperates with Haizhou Shipbuilding Industry Group and invests in Haizhou, Zhang Yiming will still have some confidence. Because Fangxia ceramics is a private enterprise, even if they have unique technology, cooperation with large state-owned enterprises will still be very disadvantageous, but if they cooperate with Haizhou Shipbuilding Industry Group, they should be able to win more preferential conditions.

However, Bao Feiyang claimed that the Shipbuilding Corporation and the 177 Institute would also participate in this project, and Zhang Yiming felt that it was too ridiculous, because the Shipbuilding Corporation and the 177 Institute are both national teams and the leaders of the industry, and Haizhou has no advantage in comparison. The project that can involve the Shipbuilding Corporation and the 177 Institute should be a national strategic project, and it should definitely not be said by a local cadre in his twenties like this.

At this time, Bao Feiyang's mobile phone rang, he picked up the phone and looked at it, and hurriedly made a gesture to Zhang Yiming: "Sorry, I'll answer the phone." ”

"Where is Mr. Ho?" Seeing Bao Feiyang walking to the side, Zhang Yiming looked at He Weijun and asked.

He Weijun doesn't know much about the shipbuilding industry, but when he saw the changes in Zhang Yiming's reaction before and after, he also knew that the amount of chips thrown by Bao Feiyang was not small, but now it seems that Zhang Yiming seems to be a little reluctant to believe it.

He Weijun stretched out his hand and touched his head: "Hehe, speaking of which makes Mr. Zhang laugh, I'm just an unemployed idler, and I usually do a small business." ”

Zhang Yiming pouted at Bao Feiyang: "Mr. Bao's courage is so big, can the people who are with Mr. Bao do small business?" I don't believe it anyway. ”

"Haha!" He Weijun smiled: "Feiyang said that Mr. Zhang is very capable, and capable people are often very confident, but confident people often make mistakes in common sense matters." ”

Zhang Yiming said: "What does Mr. He refer to?" ”

"Mr. Zhang should understand." He Weijun looked at Zhang Yiming: "Do you not believe what Bao Feiyang just said?" Although I was also shocked, since it was he who said it, I don't think the ** of ten would be wrong. ”

Zhang Yiming's eyes flashed: "Mr. He knows Mr. Bao very well?" ”

He Weijun shook his head: "I don't know very well, but I can tell you that many things that seem impossible to you may be just a gesture for him." ”

He Weijun's words are a bit exaggerated, but through Guò's understanding over the past few days, as well as the contact in the past two days, He Weijun has indeed realized that Bao Feiyang is indeed a little different, and since he said it, he is obviously certain to a certain extent.

Zhang Yiming nodded thoughtfully, but he was still a little disappreciative in his heart, and even felt that He Weijun was not so reliable.

Bao Feiyang quickly answered the phone and walked over, he looked at He Weijun, and then at Zhang Yiming: "Mr. Zhang, I am going to meet the leaders of the 177 Institute now, are you interested in going to see it together?" ”

Zhang Yiming was stunned, he didn't expect that Bao Feiyang would propose to let him go to see the leader of the 177th Institute together, he instinctively felt that there was a conspiracy, but when he thought that Bao Feiyang was introduced by Chen Wenbin of Jiangbei Provincial Shipbuilding Corporation, he felt unlikely.

"The leader of the 177th Institute?" Zhang Yiming asked subconsciously.

Bao Feiyang nodded: "Yes, is Mr. Zhang going?" ”

Zhang Yiming hesitated: "Can I go too?" ”

"Of course, today we are going to talk about civilian projects, and the secrecy requirements are not high." Bao Feiyang said: "As long as Mr. Zhang, you promise to make a temporary cameo appearance as the technical consultant of our Haizhou Shipbuilding Industry Group, then it will be fine." Of course, it would be better if Mr. Zhang was willing to join Haizhou Shipbuilding Industry Group. (To be continued.)
