On September 23, Long Jianhua returned to Kyoto from Hunan Province. When he visited his uncle, he saw that he was in a depressed state. However, his aunt was in good condition and was not ordinary.

It turns out that the working conditions of the two are now in heaven and earth.

Because Long Jianhua gave her six fan appearances, my aunt now becomes the technical director of the electric fan factory, and her work is relaxed and comfortable.

All I have to do every day is to go to the site to check it out, guide the production and assembly on site, and watch the electric fans in the factory pull out to sell it in a car.

Uncle's situation is not very good.

Originally, Long Jianhua's proposal was to buy some ready-made blanks to process the camshaft, but unexpectedly, some teachers suggested starting with the raw material - cold hard cast iron.

Zhao Taihang and others also believed that they should keep up with the world's advanced technology and make the core components in the engine, so they bought a large amount of raw materials for testing.

Long Haojun was originally responsible for the rear-channel machining part of the camshaft processing - centerless grinding, milling end faces, drilling center holes and subsequent deep hole processing. However, due to no precedent, several months have passed, no qualified raw materials have been produced.

Now, this task has fallen on him again, and he has been searching for information in various university libraries for more than a month to see if he can solve the problem of this material.

To be honest, at this stage, we can’t blame those teachers for being in poor quality, because they are not familiar with the outside world now.

Zhao Hongying laughed and said, "This is a big trouble, Jianhua, you can't stop watching. You have to go and help your uncle."

Long Jianhua expressed his grin, but also agreed to follow them and take a look.

If he wasn't afraid of being shocked, he could write down the entire process of the material production process and hand it over to him.

After following Long Haojun for three consecutive days, he pointed out that they have some problems in their current exploration, which can be said to have committed a big taboo.

In his memory, some senior experts once said that the production process of camshaft steel has five stables: the furnace feed ratio is stable, the overheating temperature and time is stable, the chemical composition is stable, the inoculant addition amount and the white mouth depth are stable.

Their current way of exploration is often the same as at least two conditions change at the same time, so they cannot find out the flaws that really need improvement, and are not the correct way to study.

There are also raw materials and scrap steel used. Some of them are rusty, some are even rusty, and some are oily, which they have not processed. When feeding, some employees are estimated to add statistics and weigh them with their hands and then pass.

After listening to his analysis, Long Haojun directed his staff to shoot blast pig iron and scrap steel to remove rust and oil stains from it.

In the opinion of the factory manager, this is good. Now there is nothing to do with this product, and it also helps the employees find something to do, so they can't let them be idle and cause trouble.

Long Jianhua mastered the rhythm of controlling the R&D.

On the 29th, the furnace material ratio was set and fixed to pig iron, scrap steel, and refrigerated material were 20%, 2.5% and 77.5% respectively.

After fixed the infusion time, three furnaces were produced continuously, with a greater strength than before and much more stable. The processed products could reach the leading level in China, which also made Kyoto Automobile Factory very interested and placed an order tentatively.

On October 1st, Zhao Liming held a wedding, and Long Haoyuan and Li Xiulin also rushed from Shajuan City to attend.

Zhao Taixing slapped Long Jianhua twice in front of Long Haoyuan and Li Xiulin, "I don't know if this kid is my lucky star or my mother-in-law is my lucky star. What I do now is what I do."

He is also proud of his youth now.

My son got married in the Siheyuan. Maybe because he had run three companies in a row, or because his age was up, he actually promoted him half a level in early September and became the deputy district mayor.

Li Xiuzi pointed at him and said angrily, "My mother has been with them for so long, but she hasn't seen any improvement. If it weren't for Jianhua, would you dare to run that store and two factories? If it weren't for Jianhua, would we have this courtyard house?"

Zhao Taihang laughed and said, "Of course I know it's Jianhua. Don't you want him to be upset?"

He pointed at Long Jianhua and said, "I heard that you and your uncle are working on technical research on the camshaft, but you need to get that thing done. The teachers said that the reason why our engines are poor is also a very important reason."

Long Jianhua said depressedly, "I thought you would choose a few simple accessories for processing, but I didn't expect that it would be a technical problem when I started, but my uncle was so worried that his white hair grew out."

When they heard that Long Jianhua helped the Machinery Factory conduct technical public relations, neither of them believed it, and they were embarrassed to ask in front of so many people. After they arrived at Long Haojun's house, they expressed their questions and did not believe that he could come up with an idea.

After Long Haojun said in a muffled manner, "His level is much better than those teachers, and now our materials are stable," the two of them looked at him with a look of disagreement.

Long Jianhua laughed and said, "This is nothing. I drove around and saw more and heard a lot, so the probability of success is much higher."

However, he suggested that Long Haojun should master the ratio by himself and not disclose it.

At this time, yours is mine, and mine is yours. It doesn’t matter to big companies, but it’s a disaster for their street companies.

Next, Long Jianhua followed his plan.

Spend three days to set the heat treatment process and two days to fix the chemically treated medium; finally, spend four days to fix the ratio of chromium and copper to the ingredients.

At this point, the camshaft materials in the machining factory have reached the international advanced level in the early 1990s, and the processing level is also at the early 1970s.

When they transferred the test items to Yiqi, Erqi and BAIC, the three factories significantly reduced their camshaft production and handed them over the orders, which was 100,000 sets at once, which was much more than their design capabilities of 10,000 sets.

Zhao Taihang was very happy when he heard the news and allocated funds to expand the factory.

Seeing Long Jianhua's success in experiments one by one, Long Haojun asked a few questions from time to time at first, but later he simply just helped him record and asked some theoretical questions.

Regarding mechanical processing, Long Jianhua just looked at it. Those who operated the machine tools were at least level 4 workers, which could be done according to the requirements. It was just that due to the backwardness of the lathe, the accuracy could not be higher and the output could not be improved.

As for management, he will not regulate it.

His concept was too advanced, and some ideas were not even accepted by Long Haojun, let alone those workers?

When the teachers from Mizuki University heard that Long Haojun had solved the material problem, they hurried over to visit, but found that they were not the only ones who came, but the teachers from Kyoto Iron and Steel College arrived earlier than them.

A teacher from Shuimu University suggested, "Comrade Long Haojun, you were originally a bachelor's degree, and you can go to our school to teach with this result."

A director of Kyoto Iron and Steel College laughed and said, "We are here today to invite Comrade Long Haojun to teach in the materials department of our school, and are helping him apply for an associate professor. You may not know that Comrade Long Haojun is a graduate of our school and is a close-knit building."

Zhao Taihang sighed mournfully, "If I had known this was the result, I wouldn't have bragged to your dean at all. I finally dug it up for a few days, but I was snatched away by you. I'm digging my own grave."

When Long Jianhua heard this, he kept talking to MMP in his heart.

He never expected such a result.

I didn't expect this achievement to attract the attention of the school so quickly. I am really eager to seek talented people.
