In fact, Zhang Yi attaches great importance to this large-scale bearing steel smelting production line. After all, as long as the bearing steel production line tests normally, it means that his Colorful Stone Machinery Factory has the ability to smelt bearing steel on a large scale. They

If the factory produces bearings in the future, it will no longer have to worry about being stuck by foreign manufacturers in this regard.

Similarly, the high-precision bearing production line that their Colorful Stone is going to test today is even more important to Zhang Yi and his Colorful Stone.

Bearings, although they look inconspicuous, are closely related to all modern machinery, whether they are running on the road or flying in the sky? They are inseparable from these small bearings. Therefore, it can be said that bearings are the cornerstone of various modern machinery.

"Master Wang, how is the bearing steel smelting going? Have the pass rate and production capacity met our design requirements?" After lunch, Zhang Yi came to the bearing steel smelting workshop again and asked Wang Hong.

"Boss, our renovated smelting equipment has been running very smoothly this morning. The first batch of molten steel was produced this morning. It has met our expected requirements in terms of performance, qualification rate and production capacity. Now we

We are preparing to process the molten steel outside the furnace. As long as it goes well, there will be no problem." After listening to Zhang Yi's words, Wang Hong answered directly.

"That's good. After you finish the smelting, you can send the smelted bearing steel directly to the bearing production plant. I will also go to the metallurgical workshop first." After saying that, Zhang Yi walked out of the smelting workshop and walked towards

Walk to another factory building across Central Avenue.

This factory is the bearing production workshop. Since these factories are more than 10,000 square meters in size, there is enough space to install a bearing production line.

The high-precision bearing production line developed by Zhang Yi and Colorful Stone can theoretically produce 30 million sets of bearings per year. If production continues 24 hours a day, the production line can reach nearly 100,000 sets.

However, in fact, the output cannot reach this much now. Even when production just started, it would be thankful to be able to reach one-tenth of the level. Although this production line is also a semi-automatic production line like the aerodynamic bicycle production line.

However, it is not a fully automatic production line, and since the production line was developed by them themselves, even if it is temporarily successful, it will still have to pass the test of time. Of course, these production lines will slowly develop towards automation in the future.

When Zhang Yi arrived at the bearing production workshop, workers in the workshop were also nervously conducting final inspections on the bearing production line.

Since the entire production line is designed and manufactured by Colorful Stone Machinery themselves, all the parts on the entire production line are brand new and have not been run-in, and there is no rust.

Not long after Zhang Yi arrived at the bearing production workshop, the bearing steel was finally sent to the bearing manufacturing workshop, and after being transported.

Zhang Yi and the others did not have any ceremony and just cut the pieces into pieces. After all, the test has just begun. If the test is completed, Zhang Yi would not mind setting off fireworks to celebrate.

Although the bearing steel at this time is said to have been smelted, in fact these bearing steels are not real finished products. These bearing steels still have to go through many processes in the process of manufacturing bearings.

As pieces of semi-finished bearing steel are put into the feed port, these bearing steels are swallowed up by the bearing production line, and the production line begins to officially operate.

This production line is nominally a semi-automatic production line, but the degree of automation is also very high. Basically, it does not require too many manual adjustments during the manufacturing process.

However, this production line can only produce one type of bearing at a time. If other types of bearings are to be produced, the machine will need to modify the data, and the mold will also need to be replaced manually.

And whether it is changing the mold or modifying the data, it is quite troublesome. If it is an ordinary worker, there is absolutely no way to modify these things in three to five days. However, since there are many technicians in Zhang Yi factory who are comparable to the ninth level, naturally

It doesn't take that long.

If Zhang Yi and his Colorful Stone wanted to produce other types of bearings, it would only take half a day with the help of these talented people in the factory.

At the same time, after the production line began its official test operation, all the academic masters present, including Jiang Shuai, closely watched the operation of every part of the production line to see if it was normal.

Especially the key parts of the production line, that is, the bearings in the production line. After all, Jiang Shuai is very confident in other parts of this production line, because he personally designed this production line, and at the same time, the parts on the production line

It was also manufactured under his own supervision.

However, the bearings on this production line are not manufactured by ourselves, but purchased from outside. Although these bearings are already the best bearings that can be purchased in China, they have even reached military-level bearing standards.

However, if these bearings are sold internationally, they will only be second-rate bearings, and there is still a certain gap between them and the truly top-notch bearings in the world.

But he is also very clear that the use of these on this production line is only temporary. As long as Colorful Stone produces the same bearings themselves, then these bearings on the production line will be produced by Zhang Yi and his factory.

The bearings were replaced.

With the production line running, Zhang Yi and the others finally waited until the first set of bearings rolled off the production line.

So Zhang Yi couldn't wait to pick up the bearing that had just been produced and look at it. It was basically impossible to tell whether a high-precision bearing like this was good or bad with the naked eye. Zhang Yi and the others still picked it up and looked at it with interest.

.

"It's so beautiful. I think the accuracy of this bearing will definitely meet our expected requirements." Zhang Yang, who didn't know when he came over, looked at the bearing and said.

When Zhang Yi picked up the bearing and observed it carefully, other people next to him also looked at the bearing in Zhang Yi's hand carefully and nodded.

But what they said was indeed true. The set of bearings that had just come off the production line was indeed very beautiful. At least they didn't see a single flaw in its appearance, because the sealing ring of this bearing was also made of bearing steel from Zhang Yi's factory.

, so even there is no gap between the inner and outer rings and the sealing ring on the bearing. You can imagine how high the accuracy of this bearing is.

Although Zhang Yi and the others could not see with their eyes whether the bearing was accurate and met the design requirements, this did not hinder Zhang Yi and the others from being happy. After all, this was the first bearing produced by their factory, and all the materials in it
Chapter completed!
