Chapter 129 The anxious 618 Factory
With a blast of cold air from Siberia, the temperature in the capital dropped to single digits.
If I don’t wear gloves in the morning, after riding to the factory, I will feel that my whole hand cannot be used.
Fortunately, after entering the office, it immediately became much warmer.
In the next period of time, Jiang Hui was either dealing with various things in the office every day, or going to a nearby supporting factory to confirm the situation. It could be said that he was too busy to keep his feet on the ground.
Of course, all this busyness must be rewarding.
Prototypes from various supporting factories are being advanced in an orderly manner. Sample delivery will begin after the Spring Festival, allowing the first new BJ212 to officially appear in front of the world.
This is a very meaningful thing for Jiang Hui and Capital Automobile Manufacturing Plant.
"Xiao Jiang, yesterday our Dacromet surface treatment process passed the expert review organized by the school, and the Fifth Machinery Department will be invited to conduct the review in the next stage."
Although Zhu Jiansheng still failed He wears the title of deputy chief engineer of Capital Automobile Manufacturing Plant, but since the design work of the new BJ212 has been basically completed, he rarely comes to work.
Basically, I come once a week, or once every two weeks, that’s about right.
“The current requirement we have set for the Dacromet surface treatment process is that no red rust will appear after at least 960 hours of salt spray testing. During the actual test, it will be required to be 1,200 hours.”
< br>"The 960-hour salt spray test has not been completed yet, right?"
Jiang Hui naturally hopes that the Dacromet process can be popularized as soon as possible, but he passed the review before the test was completed. , it feels a bit weird after all.
Don’t become a stain when the time comes, it won’t be beautiful.
"960 hours is 40 days, and we have to wait until next month to get the results."
"But after we did it for 240 hours, not only was there no red rust, there was no sign of corrosion at any other point."
“In order to maximize the speed of promotion of this technology, the heads of several departments discussed and held a review meeting within the school.”
“With At the same time, our tests have not stopped and are still going on.”
“The final evaluation results of the Fifth Machinery Department will not be official until the test is about to end.”
< br>
"But this does not affect the development of the review meeting. After all, except for the salt spray test, other confirmations have been completed."
"All aspects of data show that the Dacromet surface treatment process is a The process has very good anti-corrosion properties and is worthy of large-scale promotion.”
Jiang Hui probably understood Zhu Jiansheng’s explanation.
It seems that within the Capital Institute of Technology, people from various departments attach great importance to this achievement.
We are all professionals, and we are very aware of the huge changes that such a novel surface treatment process can bring to all walks of life in China.
Especially in the military industry, various equipment and weapons are used in harsh scenarios and have higher requirements for corrosion resistance.
"Dacromet surface treatment process, I have seen it in some information before. It was a process first promoted and used by the American military."
"This background, to It’s better to say it briefly, lest someone say that our technology is plagiarizing others.”
Although for China in this era, being able to successfully copy America’s advanced technology can be regarded as a fill-in. There is a domestic gap.
But for Jiang Hui, he definitely hopes that this thing will be as perfect as possible.
The United States has a similar process, which has been used on a large scale in the military industry system.
We combined some public information and independently studied similar processes, and we may be better than others in terms of some parameters.
If it were positioned in this way, the nature would be completely different.
Even if the Dacromet technology in the United States is made public in the future, everyone will not doubt the value of the project hosted by Zhu Jiansheng after comparing it.
“Plagiarism?”
"I do want to copy American military technology, so I have to have something to copy."
Zhu Jiansheng is not worried at all about Dacromet technology being said to be copied from the United States.
If you can plagiarize, that is a skill.
Everyone knows that America’s various advanced fighter jets, tanks, radar and other technologies are very advanced, but who can easily copy them?
“Now that the school has passed the review of Dacromet technology, can we start to prepare for application and promotion simultaneously in the future?”
For Jiang Hui, giving Zhu Jiansheng credit for his operation is one purpose, and solving the corrosion problem of new BJ212 wheel bolts and other parts is also a purpose.
Considering the urgency of time, if you want to put the Dacromet process into application as soon as possible, you must act early.
After all, the existing coating production line needs to be modified or re-invested in the production line to meet the requirements of the Dacromet process.
“We have submitted the information and propose to find a factory from the fifth machine department’s subordinate factories to renovate a Dacromet surface treatment and coating line.”
“By then this technology will be used We will also apply to Chaoyang Fastener Factory for use simultaneously. ”
Although the technical solution was provided to Zhu Jiansheng by Jiang Hui, the technology is now in the hands of the Fifth Machinery Department and is used by the factories under the First Machinery Department. Zhu Jiansheng is not suitable to give it directly to others.
Of course, Jiang Hui can also skip Zhu Jiansheng and directly guide Chaoyang Fastener Factory to transform the production line.
But then, the flavor of the matter changed, and the goal he wanted to achieve could not be achieved.
“Well, I also asked Chaoyang Fastener Factory to submit the application report itself, and both lines will act at the same time.”
Since Jiang Hui has already mastered the Dacromet surface treatment process Once the credit goes to my father-in-law, I won’t try to rob him again.
Everything just needs to be carried out according to the process.
Of course, Chen Qi was also very concerned about improving the corrosion resistance of wheel bolts before. Now that Capital University of Technology has passed the review, he must also talk to Chen Qi about this matter.
While Jiang Hui and Zhu Jiansheng were chatting about the Dacromet surface treatment process, at the 618 Factory on the outskirts of the capital, several technicians looked at the test results of the amphibious combat vehicle with sad faces.
“General Manager Zhang, our chassis parts are painted according to the process used by the shipyard, but the use of amphibious combat vehicles is still very different from that of warships.”
“Not only does it have to be soaked in water and driven, the internal temperature is also very high, not to mention the humidity.”
"In addition, it has to frequently switch between land and water conditions, and there is often various sludge on the chassis."
"So its chassis parts have higher corrosion resistance requirements than those of ships. Higher, even higher than tanks and armored vehicles.”
Wang Le, the minister in charge of chassis design, took the test report and some photos with a frown and explained the situation to the chief designer Zhang Zhuo.
At present, all the design work for the new amphibious combat vehicle has been almost completed.
Although there is still a lot of room for improvement in terms of power and armor protection, the goals of the first phase have been completed, and any existing problems can be solved first.
However, due to the corrosion resistance requirements of the chassis parts, this amphibious combat vehicle has never been able to be put into mass production.
Wang Le is under great pressure now.
“If the corrosion resistance requirements of chassis parts cannot meet our design requirements, then after the tank is put into use, not only will it need to be painted with some anti-rust paint every quarter, the key is that some parts cannot be painted through To solve the problem, it needs to be replaced regularly, otherwise it will malfunction. ”
“This will lead to a significant increase in usage costs, which is absolutely unacceptable to the relevant departments.”
“Specially. The economy is about to begin to transform, and military expenditures will continue to be reduced. We must reduce the daily maintenance costs of the user departments to the greatest extent." Zhang Zhuo was also in a bad mood.
The new generation amphibious combat vehicle is a key project of the 618 Factory, and the factory is preparing to make it a flagship product.
As a result, everything was ready, but it was hindered by a corrosion resistance problem.
You can imagine how bad Zhang Zhuo was.
If there is a problem with the engine or a problem with important parts such as the tracks, it is easy to understand.
Now he is being held back by an issue that no one pays much attention to. Zhang Zhuo feels that he will be criticized the next time there is a meeting in the factory.
“We have tried several methods, whether it is electro-galvanizing, painting, or even electro-galvanizing plus painting, but there is no way to meet the design requirements.”
“Water and land The use environment of amphibious combat vehicles is very harsh, especially in seawater, where they will be corroded by chlorine ions, which imposes very high standards on anti-corrosion requirements.”
“This is why many countries around the world cannot produce qualified vehicles. An important reason for the amphibious tank.”
Wang Le felt that it was necessary to let Zhang Zhuo understand the difficulty of the problem.
It’s not that he doesn’t work hard, it’s that this problem is too difficult to solve, and many countries around the world can’t solve it.
"How did the United States and the Polar Bears solve the problem?"
In this period, China's military products were generally aimed at benchmarking the performance of the products of the United States or the Polar Bears, and were still in the catching-up stage. .
So when we encounter a problem, everyone is accustomed to thinking about how the United States or the polar bears solved it.
This time is no exception.
"I heard that the American side has adopted a very special advanced coating process, but we don't know the specific situation."
"The technical level of the amphibious tank over the Polar Bear side is actually not special. are advanced, and because their operating temperature is not that high most of the time, the corrosion resistance requirements are reduced to a certain extent.”
Zhang Zhuo was not very satisfied with Wang Le’s answer.
Now the 618th Factory has no solution at all. Even if it wants to report, it doesn’t know how to report it.
“The amphibious combat vehicle project is a key product in the factory. Next year it will be officially mass-produced and delivered to relevant departments for use.”
"Your chassis department still has up to half a year to solve this corrosion resistance problem. It must be solved."
When Zhang Zhuo said this, Wang Le's face was immediately filled with bitterness.
He really has no idea.
"General Engineer Zhang, the Fifth Machinery Department called you to come over. They said it was a problem with the anti-corrosion of the amphibious landing vehicle, and they helped solve it."
Just here. When the atmosphere in the conference room became depressing, Zhang Zhuo's secretary came over and asked him to go to the Fifth Machinery Department for a meeting immediately.
These words were like dropping a bomb on calm water, confusing everyone immediately.
Did the Fifth Machinery Department help solve the problem?
How to solve it?
Which manufacturer solved the problem?
The people in the 618 Factory have a detailed understanding of the situation of each manufacturer in the system. Everyone's level is about the same, and it is impossible to make such a breakthrough.
Besides, even if a manufacturer's technology advances by leaps and bounds, they will definitely hear some rumors.
Why do you suddenly say it’s solved now?
"General Engineer Zhang, let me go to the Fifth Machinery Department with you."
Wang Le couldn't sit still.
To some extent, he was more anxious than Zhang Zhuo. .
After all, when the time comes to play, he will definitely be the most injured.
It is possible that the position under the buttocks cannot be saved.
“Let’s go, let’s go to the ministry first.”
After Zhang Zhuo finished speaking, he was ready to leave immediately.
The BJ212, which was leaking air everywhere, flew them towards the Fifth Machinery Department.
...
“Leader, has the ministry found a solution to the anti-corrosion problem of amphibious combat vehicles?”
When Zhang Zhuo met Wu Senmao, deputy chief engineer of the Fifth Machinery Department, He couldn't wait to ask more questions.
This matter has almost become his heartache. If it can really be solved, it will definitely be a big deal.
“Don’t worry, take a look at this report first.”
Wu Senmao handed Zhang Zhuo a report calmly and motioned for the other party to take a good look at it first.
At this moment, Zhang Zhuo was not in the mood to look at anything seriously. He flipped through it three times, and his expression became a little complicated.
At the beginning, when he saw the unique paint formula and the theoretical analysis behind it, he felt that his hope was instantly aroused.
But when he saw that the parts using this coating process did not show red rust in 960 hours or even 1,200 hours of salt spray testing, he couldn't help but look disappointed on his face. expression.
“Leader, this report is very well written and seems to be very logical.”
"But it is obviously an application to defraud project funds and is not feasible."
"How can there be such an excellent surface treatment solution in this world?"
Zhang Zhuo during this time It can be regarded as a good understanding of the technical level of electroplating and painting in various domestic factories.
Even if a very special process is used, it is far from the level in the report.
Those who engage in technology know best how difficult it is to improve technology.
In particular, surface treatment technology, which does not seem so inconspicuous, is even more difficult to improve quickly.
“Do you think this project of the Capital Institute of Technology is a fraud to obtain funds?”
Wu Senmao was not impatient and asked with a smile.
“Leader, isn’t this an obvious thing.”
“If they say that they can finally achieve no red rust after a 480-hour salt spray test, then I think it is more reliable. .”
"After all, it has about doubled compared to the current mainstream level."
Zhang Zhuo gave his reply with certainty.
