Chapter 60 60. The Frog at the Bottom of the Well

"enough!"

Gao Weiguo reprimanded loudly and lost his temper.

"It seems that the face of the dean of your Automotive Research Institute doesn't work in passenger cars." Feng Hao said with a smile, "If the employees of passenger cars are so arrogant and unreasonable and self-centered, then this cooperation, we Look or forget it."

"Don't go!" Gao Weiguo was as anxious as an ant in a hot pot, and quickly stopped Feng Hao.Passenger cars and the Automotive Research Institute belong to brother units, but the filth in the middle is not enough for outsiders to understand.At the same time, he pointed at Yang Rongyi and cursed, "Apologize to Feng Hao quickly, otherwise you will be a sinner in history!"

"Hey, you are still a historical sinner, don't give me too much credit, now is not a special period in the 70s and [-]s!" Yang Rongyi was not at all afraid.

With the sales of the Shinhwa GS4 series, the employees of passenger cars began to feel inflated, and even a few months ago in the form of a strike, a bonus equivalent to 12 months' salary was brought!They looked at the employees of the Automotive Research Institute with a hint of charity.Why should I give you money for the car produced by Lao Tzu?
It's a pity they forgot that without the design of the Automotive Research Institute, your passenger cars will be produced first?Don't forget the well digger when you drink water!

"If you don't apologize, I'll fire you!" Gao Weiguo was furious.

"Fire me? My personnel relations are not in your control." Yang Rongyi pushed back.

Gao Weiguo was choked up by these words: "Are you out of your mind? I managed to invite a great master. If you drive me away, believe it or not, I will fight to reject the position of dean, and I will dismiss you for investigation." !"

This move can be described as a trump card. One of the Tathagata palms turned into Wuzhishan to directly suppress Yang Rongyi, who was still invincible just now, and the latter dared not speak out.

Seeing that Yang Rongyi had shut up, Gao Weiguo quickly stopped Feng Hao, and said with a pleasant face, "I will apologize to you on Yang Rongyi's behalf, and I hope that you, an adult, will not remember the fault of a villain. In the sense that domestic cars are discriminated against by foreign car companies, you can help me solve the engine problem. The problem."

After finishing speaking, Gao Weiguo bowed down and apologized as a dignified dean and a department-level cadre to keep Feng Hao!

Faced with such a sincere Gao Weiguo, Feng Hao warned: "Don't be an example!" After speaking, he went straight to the first link of engine production, the sand model.

Sand mold, as the name suggests, is a mold made of sand.In this sand mold, there will be many holes and vacancies designed for the next process.

To ensure that the microscopic data of the engine prototype produced in the next process are normal in all aspects, the sand mold must be carved by a very precise machine.

The accuracy of the sand mold is extremely high, even if there is an error of one millimeter, the final engine may be a waste product.

This kind of precision machine tool, even if it is an independent brand of self-developed engine, uses products from Germany, RB, Italy and other developed countries in precision machine tool technology.

Looking at the sand molds produced by precision machine tools from Germany in front of him, Feng Hao frowned slightly.

"What's wrong?" Gao Weiguo felt strange and asked, "Is there a problem with the machine tool?"

"There is no problem with the machine tool, but there is a problem with the sand mold produced." Feng Hao replied.

Yang Rongyi was about to open his mouth to refute, but was glared at by Gao Weiguo, so he could only hold back his words.

Posing!Whether it is manual sand model inspection or machine review, all have reached the data standard!Can you see the problem with just the naked eye?Do you think you are Sun Wukong, with a pair of piercing eyes?
Feng Hao pointed to a hole in the sand mold and said, "The arc here is wrong, there is an error of 0.34 millimeters."

When Yang Rongyi heard it, he was immediately happy.You can accurately measure the error to the level of 0.01 mm with the naked eye. You are not a sharp eye, you are simply a microscope!
He could not ridicule Feng Hao, but he had other means. He called a quality inspector and asked him to go up and test it. He wanted to use the facts to slap his face. It turned out that there was a real error. Although it was not 0.34mm, it was still close, 0.32mm !

As soon as the test data came out, the audience was in an uproar.

This is too arrogant.

Yang Rongyi felt very ashamed, and slandered in his heart, shit luck.

Although the error is only 0.32 mm, which does not reach the error of 1 mm, as a super-class engine, this error cannot be tolerated at all.

Gao Wei Guoyu said earnestly: "Everyone, we are trying to produce a super-class world-class engine instead of an outdated domestic engine. Therefore, please cheer up, abandon old ideas, old ideas and old traditions, and work with a realistic attitude!"

After saying this, he deliberately looked at Yang Rongyi.

This is the downfall!
Immediately, Yang Rongyi became angry from embarrassment and blushed.

"Then what should we do now? Shall we make sand models again?" Gao Weiguo asked Feng Hao.

"No, it's too troublesome, and I don't have the time." Feng Hao refused, and continued to move forward to the second process: casting.

Casting is divided into four steps, the molten iron is melted, the casting is started, the metal is cooled, and the mold soil is knocked out.

But before casting, all sand molds will be transported by machine to the designated canning area.Here, the sand molds are heat-resistant and fastened.Prevent small structural changes in the sand mold and affect the yield of the engine.

The high-temperature furnace for melting molten iron is very important. Will the furnace wall material release impurities at high temperature and weaken the rigidity of the metal material?Similar to precision lathes, high-temperature furnaces also rely on imports.

Regardless of the heat, Feng Hao carefully watched the molten iron poured from the high-temperature furnace into the sand mold, and the engine blank was formed after the metal cooled.

This process is also crucial, and even the process control of cooling metal is a technology that is strictly kept secret by every car company, especially the first-tier car companies, because this step affects the quality of all aspects of the engine, and it is the most demanding step in engine manufacturing.

Thanks to Feng Hao's technical information, the passenger car has adjusted the cooling control technology, so that the metal cooling fully meets the requirements of the first-tier car companies, ensuring that the engine blanks knocked out of the mold soil have sufficient quality.

There is no problem with the high-temperature furnace and metal cooling, but there are errors in the sand mold of the first process, and the produced engine blanks naturally also have errors, but it is not irreparable.

The next steps are roughing and finishing.

The engine blanks are processed and polished using imported machines from developed countries with precision instruments such as Germany.Due to the change in the design and structure of the engine, the processing machines of the GS4 production line are not precise, requiring technicians to use lathes based on experience, manually reprocess and polish auto parts that meet the technical requirements.

Feng Hao said that the way to fix the sand mold problem is here.

He has to personally go into battle and turn the engine rough out to the required level.

By the way, let the frog in the well know that there are heaven and there are people outside the sky!
