Chapter 182: A bump in the road, the Hummer prototype is coming
“Based on the information given by Professor Zou, are you confident in producing a new generation of bearing steel?”
Of course Zhou Gang is He hopes that Shougang can also launch new products, but as an industry professional, he is also very aware of the difficulty of developing a new steel product.
It is somewhat unbelievable to immediately develop a new product based on some information given by the other party.
If it were really that simple, then China could obtain some information from overseas steel mills through various methods.
Thus, the domestic steel technology level will be greatly improved.
“I think we can give it a try. Even if there is no way to significantly improve the technical level of our bearing steel in the end, at least it will have better performance than the current products. There should still be hope.”
Zuo Guangsheng didn’t dare to guarantee it.
After all, the information Zou Yuan left for them was relatively limited, and many details were not fully reflected in the information.
The most important thing is that according to the news he heard, Xingshan Iron and Steel did not successfully produce a new generation of bearing steel in one go.
It was only after some adjustments that they finally succeeded.
Shougang definitely doesn’t know the details of the adjustment.
Even if Zuo Guangsheng went to inquire, nine times out of ten he would not be able to find out.
Although there is no patent law in this era, various factories still have some sense of confidentiality regarding the products they produce.
Especially with the economic reform, the pressure faced by various factories has begun to increase.
The past situation of guaranteed harvests due to droughts and floods will gradually be broken.
"If that's the case, then go ahead and give it a try."
Zhou Gang sighed in his heart. If he had known it, he would have arranged for personnel to seriously cooperate with Capital Institute of Technology and Capital Steel. If you go to the college to conduct the test, you won't have so many worries.
……
“Assistant Jiang, we have made some modifications to the 4MT manual gearbox based on your tips. Now the bearings produced using a new generation of bearing steel have significant performance improvements. Promote.”
"This time, we will definitely not hold back any more."
Ji Hua looked at the newly assembled 4MT with confidence on his face.
Some time ago, Capital Gear Factory had a problem with the 4MT used in Humvee military vehicles. He was under great pressure.
“I heard that you are planning to take this opportunity to enter the truck transmission market?”
As an important supplier of the Capital Automobile Manufacturing Plant, Capital Gear Factory, every move Jiang Hui makes is very important. concerned.
Trucks are China's most important production model now, and the future output will not be low.
The gearbox market is also considered a relatively large market.
The most important thing is that domestic truck gearboxes are a little different from cars. Later generations have basically achieved domestic production. On the contrary, automatic gearboxes for cars are basically products of foreign brands.
Transmission manufacturers such as ZF, Aisin, and JATCO basically monopolize the automatic transmission market.
This is because truck transmissions are generally manual transmissions, or AMT transmissions developed based on manual transmissions.
This product effectively avoids many difficulties and problems with automatic transmissions, allowing domestic companies to master production technology relatively easily.
Like Fast in later generations, they have been very successful in the field of truck transmissions and can compete with ZF and other companies in the international market.
Now that the Capital Gear Factory has the idea to develop truck gearboxes, Jiang Hui will definitely support it.
“We do have this idea, especially now that there is a new generation of bearing steel, we are more confident in producing truck transmissions.”
“Domestic trucks, Whether it is FAW, Second Automobile Works, or models produced by other factories such as Hongyan, although they all use domestic gearboxes, they are technologies from more than ten years ago. Compared with internationally advanced products, they are completely inferior. Any competitiveness.”
"I hope that the Capital Gear Factory can make use of the production experience of 4MT and make a difference in the field of truck transmissions, so that our truck transmissions can slowly catch up with the international advanced level."
I have to say , Ji Hua is still a bit ambitious.
His ambition has brought a lot of favor to Jiang Hui.
“I think your idea is quite good. Domestic truck transmission and engine technologies are still relatively backward, and there is still a lot of room for improvement.”
“China has a vast territory. As the economy develops, the demand for trucks will definitely increase. ”
"The existing technology is definitely unable to meet the market demand."
"If Capital Gear Factory can take the lead in launching a new generation of gearbox that meets the requirements of trucks, then the future is definitely worth looking forward to."
"Maybe you can also become a star company in the First Machinery Department System."
If an important part like the gearbox is done well, it will definitely become famous all over the country and even the world in the future. things.
Jiang Hui is really optimistic about Capital Gear Factory’s decision.
"Part of the gearboxes we are currently delivering to the Capital Automobile Manufacturing Plant are settled at unplanned selling prices, which is equivalent to bringing some additional income to our factory."
"In addition to using part of it for To improve the welfare of the workers, the rest of the factory is going to invest in the development of a new generation of truck transmissions."
"I will ask for your generous guidance, Assistant Jiang."
Ji Hua's words were not polite words.
He really hopes Jiang Hui can take the time to go to the Capital Gear Factory for guidance, otherwise he really doesn’t know how many years it will take for the factory to successfully develop a gearbox product that meets customer expectations. .
Wherever it is like a 4MT manual transmission, the results will be obtained so quickly.
“If we communicate more, there will be no problem.”
Jiang Hui and Ji Hua chatted for a while, and then continued to the nearby Capital Internal Combustion Engine Factory to confirm the prototype of the high-power diesel engine. Readiness.
Compared with other products, the development of high-power diesel engines is definitely a component with the highest technical threshold in the Hummer project.
Although the Capital Internal Combustion Engine General Plant has produced diesel engines before, the displacement is completely different.
Many people may not be aware of the difference between small-displacement diesel engines and large-displacement diesel engines.
This is not just about enlarging the size of various parts and then the product comes out.
The coordination between the cooling system, lubrication system, etc. of large-displacement engines requires a higher technical level and more complex control systems to ensure stable operation.
Large-displacement diesel engines are also more complex in power output and torque control, requiring more precise electronic control systems to achieve them.
Furthermore, due to large displacement and high load, large-displacement diesel engines require higher fuel injection pressure and more complex combustion chamber shapes to ensure complete combustion of fuel. What’s even more troublesome is that large-displacement diesel engines have higher requirements in terms of materials and manufacturing processes.
Due to the large size and high load of components, large-displacement diesel engines need to be manufactured with materials with higher strength, higher temperature resistance, and more corrosion resistance.
At the same time, the manufacturing process of large-displacement diesel engines is also more complex and sophisticated, requiring the use of more advanced processing technology and equipment to ensure the accuracy and performance of components.
These problems are very troublesome to solve.
Fortunately, Jiang Hui did not expect that the large-displacement diesel engines produced by the Capital Internal Combustion Engine Factory would reach the level of later generations.
"Assistant Jiang, although all samples of our 6.5-liter turbocharged diesel engine have been produced, the processing accuracy and strength of many parts need to be improved."
"The current A diesel engine is more of a model, and the actual performance indicators are far from meeting our design requirements.”
“In the next step, we plan to simultaneously develop materials performance improvement, processing accuracy improvement, and structural optimization. We strive to make this diesel engine ready for mass production as soon as possible.”
Compared with the sample preparation work of other parts, the situation of high-power diesel engines is not particularly ideal.
For loading, you can take out the product and load it into the truck, and confirm some dimensional information.
However, the performance of the diesel engine is far from meeting the design requirements.
Cheng Tao also knew this very well.
Because of this, not long after he saw Jiang Hui, he took the initiative to report on the situation of the high-power diesel engines in the factory.
Anyway, this problem will be exposed sooner or later. Rather than being exposed by others, it would be better for him to expose it himself.
I can still manage to win a relatively good impression score with Jiang Hui.
"In terms of material performance improvement, Shouchi itself can do relatively little. The main thing is to urge supporting manufacturers to improve their level in this aspect as much as possible."
"But in terms of improving processing technology, I think there is still a lot to be done. The space is worth the effort."
"For example, this engine piston..."
Jiang Hui discussed the design improvement direction of each component with Cheng Tao very seriously.
Several professors and associate professors from the Department of Thermal Energy and Power Engineering of the Capital Institute of Technology were also recording something very seriously.
When Jiang Hui was still in school, he was very famous in the Department of Vehicle Engineering.
Thermal Energy and Power Engineering major, as a major that studies engines, boilers and other related power products, has a lot of intersection with the Department of Vehicle Engineering.
So many people in the department know Jiang Hui.
In addition, Jiang Hui has achieved such great success in more than a year of work, and everyone knows it well.
So now I am keeping records honestly.
The teachers at the university were recording information there conscientiously, and the Capital Internal Combustion Engine Factory was naturally not far behind.
Even if his skills are not good, if his attitude is also considered not good, Jiang Hui may change his mind.
Cheng Tao and the others also heard that Shougang’s attitude towards cooperation was not very good. As a result, the Capital Institute of Technology and the Capital Institute of Steel approached Xing Steel to cooperate in the technological research and development of a new generation of bearing steel. Now they have achieved A very good result, one of the most outstanding achievements of the First Machinery Department this year.
“Assistant Jiang, in order to carry out fine processing of key components such as cylinder blocks and cylinder heads in the machine shop to ensure that the processing accuracy and surface roughness meet the requirements, and at the same time, during the assembly process, ensure that each component is clean and Lubrication, and ultimately ensuring assembly accuracy and sealing, we have submitted an application report for equipment procurement to the department. "
"The characteristics of the diesel engines we produce will definitely be greatly improved."< br>
Cheng Tao knew that the Capital Internal Combustion Engine General Factory was definitely lagging behind today's sample confirmation work.
Other supporting factories can basically produce samples that meet the requirements.
Even if some improvements are needed, they are often the kind of improvements that can be completed in ten and a half days.
Unlike the Capital Internal Combustion Engine Factory, the problem is still relatively big. Although the prototype can work normally, no matter whether it is abnormal noise or the rated power, rated rotation rate, working cycle efficiency and other performance parameters of the diesel engine, it Does not meet drawing design standards.
This is very embarrassing.
"The transformation of equipment, the improvement of workers' technical level, the improvement of material performance, and the optimization of processing technology all need to be carried out simultaneously."
"All our samples will be produced within this year, and then The first batch of prototypes were assembled for testing.”
“This preparation time is very tight, Shouchi cannot keep delaying,” Jiang Hui said in a serious tone. .
If you want to be a good Party A or a good leader, you must not be laughing and joking all the time, otherwise there will be no authority at all.
Be serious when you should be serious, smile when you should be smiling.
This seems to be somewhat similar to talking to people and talking to ghosts.
"Shanghai Diesel Engine Factory and Jinan Automobile Manufacturing Factory have both approached us and want to provide diesel engines for the Hummer military vehicle project."
"But we have not agreed to each other now."
“The Shouchi prototype must be produced by the first quarter of next year at the latest, and it must be capable of large-scale mass production by the end of next year.”
"Otherwise, the military representative may want to talk to you."
Zhu Jiansheng also interjected from the side.
Although he knew that the technical level of domestic diesel engines was what it was, Shouchi's performance this time was already pretty good.
But you should be stricter when you need to be strict. Otherwise, the pressure on the other party is not strong enough, and the efficiency may not be satisfactory.
“It’s already November, and there are less than two months left. We have tried our best to solve the problems in the assembly process of this prototype and produce a new batch with better performance. The prototype was delivered to the 618 Factory.”
Although the pressure was great and the time was tight, Ji Hua finally made his promise.
If it doesn’t work, the engineers in the factory work extra overtime.
Anyway, this year there are unplanned orders to support the Capital Automobile Manufacturing Plant. The profit level of their factory has been greatly improved, and various subsidies and benefits such as overtime pay can be provided to those who work overtime.
In this era, as long as money and honor are given, the fighting spirit that engineers can unleash is definitely much more exaggerated than that of Ling Lingqi in later generations.
“Okay, then let’s send this prototype to the 618 Factory first. Even if it is just used as a model, it is better than leaving the engine compartment empty.”
Jiang Hui did not continue to force Ji Hua, but was ready to start the production of Hummer's first prototype.
