Chang Haonan, as the chief designer, is also reasonable to answer the doubts of some Party B suppliers.

However, today's occasion is really not suitable for a long speech, and with the limited time and conditions, it is impossible to answer them in detail one by one.

Moreover, the on-site commander is Yan Yongnian, and he should have been in charge of this work.

Therefore, after Xiao Lu's hand, Chang Haonan just wrote down a few more critical or interesting questions.

For example, as mentioned earlier, the determination of the casting process of large castings is guided by numerical calculations, which is essentially a multi-field composite problem of temperature field and stress field.

This is not only the research direction of Chang Haonan's next plan, but also one of the difficulties that must be overcome when the turbofan 10 is put into production.

Because in essence, the production of turbine discs and turbine blades is also a casting process that controls the growth of single crystals.

As for those parts that are relatively easy to solve or are not very important, they can only let Yan Yongnian and Liao Xinhua dock.

Immediately after that, it was time to move on to the next topic.

That is, the selection of secondary suppliers and the availability of them.

"This part is all paper materials, and it has nothing to do with the on-site situation, let's go to the car and talk, shall we?"

Chang Haonan proposed.

It's still a little cold on the riverside in April.

I didn't feel it when I first came over, but after a long time in this station, I really felt a little bitering.

Since Party A's father spoke, the meeting venue was transferred from the half-finished construction site to the minibus that Chang Haonan had just sat on.

Although there are not many locations, not all Party B has the problem of secondary suppliers, such as Baoshan Iron and Steel is from ore smelting to finished product welding is all completed by itself, and naturally there is nothing to report.

In short, it was a little squeezing, but I was still able to sit down.

"Mr. Chang, according to your requirements, our selection of suppliers is oriented to the optimization of supply efficiency, and there are no mandatory requirements in terms of cost and localization."

Yan Yongnian handed a summarized form to Chang Haonan, and said at the same time:

"However, considering the significant impact of the die forging press project, and there are plans as a gift for the 50th anniversary of the National Day, there must be no mistakes, so for the vast majority of secondary suppliers, we have arranged AB backup, even if the first choice is wrong, I can start the alternative as quickly as possible."

Chang Haonan looked at the report in front of him and nodded with satisfaction.

Yan Yongnian's performance in mechanical design can only be regarded as decent, but when it comes to engineering practice, it is indeed very thoughtful.

"Although the localization rate of the project itself is not the highest priority, it is still necessary to do it as soon as possible for the localization of imported parts."

Chang Haonan raised his head and looked at the group of Party B representatives sitting around:

"The industrial scale of our country is developing very fast, especially now that there are no policy restrictions, so it is impossible to manufacture this unique seedling of heavy-duty die forging presses, and your business is indispensable behind it."

"What's more, there are a variety of other heavy equipment, such as large cranes, loaders, shield equipment, mining equipment, these can not be counted, as long as it is currently the equipment that needs to be imported from abroad, there is room for our domestic manufacturers, even if it is not our equipment industry division of the main project, but also need to find a supplier, when you start early, the product is complete, the price is low, it is definitely a stable first echelon."

These words are no longer just about facts.

It is simply to point out the way for these enterprises that have just been transferred from the Ministry of Machinery Industry to the Commission of Science, Technology and Industry for National Defense, and their business may not be stable.

Some people who reacted quickly even took out a small notebook and wrote down the categories that Chang Haonan just casually said for example.

After all, this is likely to be the next wave of machinery manufacturing.

If you can catch it, you can take off in an instant.

It has been almost a month since the establishment of the Equipment Industry Division.

Anyone with a discerning eye can almost see that the relationship between the director and Chang Haonan is very close.

It's just that most people still subconsciously feel that it is Lan Xinzhi who wants to use the latter's mouth to deploy the work of the Equipment Industry Division.

But there are still a few people who have glimpsed some of the truth and realized, or at least begun to suspect, that the reality may be quite the opposite.

However, Chang Haonan didn't pay much attention to the psychological activities of others, just continued to look at the table in his hand, circled some places involving imported raw materials or parts from time to time, and annotated them on the side.

For example, "this part of the market is too small, there is no need to use the power of the state, and it can be completely handed over to the market" and so on.

Soon, he noticed something that was different from the previous one.

"In this part, why is it not written that the two suppliers are A and who are B?"

Chang Haonan picked up the form and pointed to a parts supplier of a spindle gearbox and asked.

Hangcheng Gearbox Group Co., Ltd., which is responsible for the production of forging press gearboxes, is mainly engaged in the production of marine power gearboxes, and has also begun to contact other businesses after belonging to the Equipment Industry Division.

The representative of Hangya was quick to explain:

"This is the crossed cylindrical roller bearing in the gearbox, regardless of priority, the plan is to use a 50:50 ratio, string Bingcheng Bearing Group and Japan NSK Group of the same label products."

This gameplay directly stunned Chang Haonan:

"Products from different manufacturers are packaged in series...... Won't it affect the stability of the gearbox? ”

In general, standard parts such as bearings, gears, screws and nuts involve too many processes, so even if they are products of the same specification produced by different manufacturers, or even between different batches of products of the same manufacturer, even if they meet the relevant standards, there will be some slight differences.

As a result, it is rare to choose to string together parts from different sources unless there is a need for anything other than the technical aspects.

"That's right."

The other party hurriedly explained:

"NSK has been the main supplier of our Hangzhou Tooth Factory in the past, but this time, during the bidding process, we found that the performance of the samples submitted by Ice Axis Group and NSK was almost identical, as if they were produced using the same process, and the domestic parts were cheaper."

"In this case, the ice shaft should have been directly designated as a priority supplier, but I am still worried that there will be any non-technical problems, after all, this consistency is too strange, so we signed two supply agreements at the same time, if the ice shaft products are no problem, then gradually begin to cooperate with them, if there are other problems, there is still room for recovery, so as not to delay the progress of the forging press project."

"Non-technical issues?"

This statement made Chang Haonan stunned.

The man continued:

"In this matter, we can only speculate that the Ice Axis Group technically refers to the process of NSK, but in what form is this reference carried out...... I can't be sure ......."

Now Chang Haonan understood.

It is a concern about the legal risks related to the intellectual property part.

In fact, for those who don't know the inside story, there is nothing wrong with this worry.

What level did you Ice Axis Group have in the past, everyone knows in their hearts.

I haven't seen it for a year, so I took out a sample from the crotch of my pants that is at the same level as the top foreign manufacturers, and even the details of the performance indicators are so consistent.

Anyone has to mumble in their hearts.

But the problem is that Chang Haonan knows the inside story.

The technology of the Ice Axis Group was even sold by him.

Although the product developed at that time was a bearing group for the turbofan 10, others also had subjective initiative, which has passed for more than half a year, and it is not surprising to draw inferences from one another and come up with something new.

In short, there is no need to take the risk of copying someone else.

"Are you sure the results of the test are almost identical?"

Chang Haonan confirmed again.

The other person nodded:

"To be sure, we also specially found two third-party institutions to conduct blind tests, and the final report conclusion was the same."

Hearing this answer, Chang Haonan took a deep breath and leaned back tactically.

At the same time, I already have a conclusion in my heart -

It was the NSK Group that made the fake......
