Sail across the sea

Chapter 129 Is there a solution?

"Why haven't you mastered the cleaning technique?" Zheng Linong asked calmly.

His attitude showed that he had a long-standing understanding of what Cao Yangcheng said, and it could even be guessed that he was here for this matter.

Cao Yangcheng looked embarrassed, and said: "Minister Zheng, the main reason for this matter is that our work is insufficient, and the secondary reason is that the polyester equipment we introduced is already a little behind in technology. According to I understand that this device is a technology developed by Okaya in the mid-60s, and it has been more than ten years ago."

"Did you know about this situation in advance?" Zheng Linong turned to Feng Liansong and asked.

Feng Liansong nodded and said: "We have already learned about this situation when we first negotiated with the Japanese side. The choice of Okaya's equipment is mainly due to price considerations. At present, the most advanced polyester plant technology in Japan is Liushan Club, but the price of their equipment is [-]% higher than that of Okaya.

"The country began to reduce the scale of imports from the year before last, and severely restricted our foreign exchange quota. We also weighed it over and over again. Considering that Okaya's equipment is also good, we finally chose Okaya."

"Oh, I understand." Zheng Linong replied, and his attitude could not be heard in his tone.He gestured to Cao Yangcheng and said, "Go ahead."

"Continue?" Cao Yangcheng was taken aback for a moment.He made self-criticism just now, and emphasized that the equipment itself is a little backward. In fact, he has already explained the reason, so what should we continue now?

But the minister told him to continue, and he couldn't just say nothing.He turned his head to Chai Huanhua, the chief engineer in the factory, and said, "Old Chai, why don't you explain to Minister Zheng the cleaning of the polymerization kettle. I'm afraid I can't explain the technical things clearly."

Chai Huanhua helped his glasses on the bridge of his nose, and said: "This problem, Director Cao said just now, the technology of this equipment is relatively backward. According to our comparison with other polyester equipment introduced in China in recent years, there are mainly five deficiencies in one aspect.

"First, there is a lack of effective liquid level control and material feedback system. Fluctuations in the liquid level of the post-polymerization kettle can easily lead to scaling on the kettle wall, and the catalyst pipeline is also prone to blockage...

"second……"

As soon as he said it, he began to speak technical jargon, regardless of whether others could understand it or not.Gao Fan sat on the far side, peeking around, and found that the performances of several people on his side were different:

Zheng Linong lowered his head and quickly took notes in his notebook. Judging by his writing speed, if he wasn't drawing a pig's head, then he should have understood Chai Huanhua's story.

Feng Liansong was a little absent-minded, probably because he didn't understand, and at the same time he didn't want to understand.

Wu Zhefu was also taking notes, but the nib of his pen was obviously a little rough, and he didn't know as much as Zheng Linong.

The most interesting thing was Pan Yue. He sat there, looking around, and looked at Chai Huanhua from time to time, with a bit of disdain in his eyes.

"...The situation is like this." Chai Huanhua finished his presentation on the technology, and finally concluded: "The production cycle of our equipment and the polymerization kettle is about two months, and then it needs to be cleaned.

"When cleaning, the bend pipe of the polymerization kettle needs to be disassembled. The work intensity is very high, and the technical requirements for disassembly are relatively high. Our workers have learned from Japanese technicians several times, but it is still difficult to master all the essentials.

"Every cleaning still needs to be done by Japanese technicians, which is why we want to keep them."

"Then how many times do you think it needs to be cleaned before our workers can fully grasp the essentials of the operation?" Zheng Linong asked.

Chai Huanhua looked at Cao Yangcheng, but did not dare to answer without authorization.Cao Yangcheng hesitated for a moment, then said: "Minister Zheng, we don't dare to make a clear guarantee on this issue.

"The polymerization kettle in Okaya has a relatively complicated structure. We dare not move it without knowing it. Every time we ask Japanese engineers to dismantle it, the place is relatively narrow, and our people can't get in, so ..."

He didn't go on, because the following words were really hard to say.

Such a set of equipment with an investment of more than [-] million yuan, no one dared to act rashly.In the case that its own workers did not grasp the essentials, the factory did not dare to let them dismantle the elbow of the polymerization kettle, so the Japanese could only do it.

But in this way, their workers will not get the opportunity to exercise, and they will not be able to grasp the essentials, so the next time they clean, they have to let the Japanese do it.

Zheng Linong asked Cao Yangcheng when the workers of Huanglan Chemical Plant would be able to master these essentials.But according to this routine, it is impossible for them to master it in a lifetime.

The question is, can Cao Yangcheng say this to Zheng Linong?

Zheng Linong understood Cao Yangcheng's subtext, and he asked, "Don't you have any solutions?"

Cao Yangcheng said: "We have been trying to find a way. During this time, before cleaning, we are asking Japanese engineers to explain the essentials of operation to our operators, so that our people can participate more next time. .”

"Is there any way in the hall?" Zheng Linong turned his head to Feng Liansong and asked.

What Cao Yangcheng said was actually saying that he had nothing to do, but he just said it nicely, which is equivalent to the meaning of "repeatedly defeated and fought repeatedly".It was inconvenient for Zheng Linong to expose him, so he could only ask Feng Liansong.

Feng Liansong said: "Lao Cao and the others have also reported this matter to the hall, and the hall is also actively trying to find a solution. We plan to contact Nanqing and Qidong and arrange for Huanghua's operators to go to them Let’s learn, they are engaged in polyester earlier and have more experience than us.”

"It's useless." Pan Yue said lightly, "The equipment in Nanqing was imported from France, and the equipment in Qidong was imported from West Germany. Qing and Qidong studied, and after learning, they still can't solve the problem of yellowing."

"Is that so?" Zheng Linong looked at Chai Huanhua and asked.

He didn't ask Cao Yangcheng because Pan Yue was talking about technical issues, and Chai Huanhua must have more say in such questions.

Chai Huanhua said hesitantly: "What Director Pan said is true. The polyester devices in Nanqing and Qidong are not the same as ours. The problems we encountered, they don't exist, so..., uh , but stones from other mountains can also attack jade."

Zheng Linong knew what was going on, and he turned to Pan Yue again, and said, "Director Pan, in your opinion, is there any way to solve the problem of Huang Hua's device?"

"This is..."

Pan Yue looked at Cao Yangcheng and then at Feng Liansong, hesitating whether to say or not.
