King of Industry

On the podium, Antonio Ducati's speech has already begun.

The topic of his speech is Application and Status of Motorcycle Aluminum Materials in the World.

The characteristics of aluminum alloy, I think all the professionals here must know everyone. It has many characteristics such as light weight, good texture, and wide application.

At present, the application of aluminum alloy materials on motorcycles with a displacement of more than 125ml is very common. However, compared with the usage rate of other alloy materials on motorcycles, the application of aluminum alloy materials is still much inferior.

Today, the topic I want to discuss with you is the prospect of aluminum alloy in the motorcycle industry...

At the beginning of the speech, Antonio Ducati quickly used his unique entry point to introduce everyone into the topic.

Under the podium, listening to Mr. Antonio's eloquent talk, Zhao Guoyang nodded silently.

In fact, in the era before Zhao Guoyang's rebirth, the promotion and application of aluminum alloys gradually became popular in the global motorcycle manufacturing industry.

Moreover, it is widely used in relatively high-end cruisers, special vehicles and other models.

Judging from Zhao Guoyang's knowledge reserve of 20 to 30 years beyond this era, Mr. Antonio was able to vigorously advocate the use of aluminum alloy in the motorcycle industry in the early 1990s, which can be regarded as having a very advanced vision.

Li Kejian on the side caught a glimpse of Zhao Guoyang's approval, and couldn't help asking: Why, Guoyang, do you also do research on materials science? Are you clear about the characteristics of this aluminum alloy material?

After hearing this, Zhao Guoyang's expression froze.

Seeing Mr. Li's expectant gaze, he coughed lightly, touched his chin and said, Mr. Li, I just learned something when I was on a business trip to Shagang Group in terms of materials science. At most, I can only It’s just a matter of knowing a thing or two…”

Hearing this, Li Kejian seemed to think of something, so he said uh, Shagang Group, I know this.

Chairman Shen Zhirong is a character. As long as he is in charge of planning, there will definitely be a place for Shagang Group in our domestic steelmaking industry in the future!

For Mr. Li's judgment, Zhao Guoyang recognized it very much, and immediately nodded in agreement.

By the way, Shagang Group should be able to do the new aluminum alloy pressure castings that Antonio just mentioned, right? Li Kejian asked Zhao Guoyang casually, tilting his head.

Well, it should be possible. This material is currently widely used in bicycles. The welded body of S35C and the overall forged pedal of A2107 can be used instead of aluminum alloy die-casting parts.

In this way, in terms of construction cost, it should be able to cut a large piece! Zhao Guoyang said casually.

What he didn't notice was that after he said these words, a smile like an old fox appeared on the face of Mr. Li next to him.

When the two were communicating in low voices, Antonio Ducati on the stage had already reached an important point.

As we all know, the application of aluminum alloy on the frame is the lowest proportion of all parts. So today I want to focus on discussing with you, it is precisely this topic...

After Antonio's words came out, Li Qinan and Sun Zhengxiao in the back row just looked at me and I looked at you, with confused expressions on their faces.

After a while, Li Qinan came to his senses first and said: Mr. Sun, Mr. Antonio, is he talking nonsense? As for the frame, aluminum alloy is used. Isn't this a nonsense? There is a need for discussion?

Li Qinan's words are not just talking nonsense, motorcycle frames have very high requirements for rigidity.

The reason is simple, the frame is another important part of the motorcycle besides the core engine.

If the rigidity is too low, the frame will bend and deform due to the moment generated by the rear wheel force.

Affecting the natural handling feeling of the riders is second to none. If the deformation is serious, car crashes and fatalities are likely to happen.

Therefore, in the domestic motorcycle manufacturing industry, the frames are usually made of materials with higher strength.

As a light material, aluminum alloy has not been applied to the frame by any manufacturer.

Listening to Li Qinan's complaints, Sun Zhengxiao at the side also expressed his agreement with a solemn face.

Although their Jialing Group is currently considered by many industry insiders to be the leader in the domestic motorcycle industry, judging from the market feedback to various companies, it is obvious that the frame of the heavy riding group has received a higher evaluation.

Therefore, in terms of body structure and frame, Sun Zhengxiao did not dare to call himself the boss.

While these two were discussing in a low voice, on the other side, Mr. Kawasaki from Kawasaki Co., Ltd. was also discussing in a low voice with his beautiful assistant Kiko Aso.

Mr. Kawasaki squinted his eyes and sighed softly: Xiko, Mr. Antonio, you really dare to think about it!

Although the application of aluminum alloy castings on motorcycle frames has existed for a long time. But there have not been many successful examples all the time, right?

Kiko Aso nodded slightly and said: Hayi, President of Kawasaki! As far as I know, the application of the all-aluminum frame should be on the road racing special car (DUCATI500) in 1979 at the earliest.

It's just that, in order to avoid controversy at the time, the body of this car was painted black to conceal the original appearance of the all-aluminum frame.

Yu Kawasaki gave a huh, nodded and smiled and said, That's right, if Ducati hadn't done this at the beginning, those racers probably wouldn't dare to drive this car, ha ha!

Kiko Aso smiled reservedly, and continued to speak: Yes, President. This matter was not officially disclosed by Ducati until 1987.

The purpose, of course, is to prove that we are one step ahead in aluminum alloy frame...

Yaoxi, that's true!

Kawasaki Yulian nodded and said: Since Harley's HD550 in 1984 and Honda's RZV500 in 1985, various manufacturers have stepped into the field of aluminum frames. Ducati is naturally unwilling to be lonely, and can't help but announce About my previous 'glorious deeds'.

Kiko Aso responded, and said with a slight smile: Yes, Ducati's application in this area is indeed ahead of the industry, and even BMW, Harley and other companies have to admit it!

Hehe, even if they admit it, they won't say it! Kawasaki Mi smiled and waved to Kiko Aso.

Okay, let's continue listening. Look at what this Mr. Antonio has to say!

On the podium, Antonio was in high spirits, declaring the prospect of the application of aluminum alloy frame.

He raised his arms and said in a loud voice: As everyone knows, the requirements for motorcycle frames are nothing more than three aspects: one is to have better rigidity; the other is to reduce the weight as much as possible while achieving controllability. ; The third is that it must be able to resist the strong vibration of the high-performance engine.

Speaking of this, Antonio Ducati paused for a moment, and jokingly said: Of course, aesthetics is definitely one of the requirements for the frame. Even if I don't say this, everyone should understand it.

Listening to the ridicule of this thin Apennine man, the audience in the audience just smiled knowingly.

Li Kejian, who had been listening carefully, couldn't help asking Zhao Guoyang after hearing what Mr. Antonio said: Guoyang, how do you understand this aluminum alloy frame? Do you think it may be used in our domestic cars? Can it be realized in frame production?

Zhao Guoyang was stunned for a moment, then shook his head and said, Mr. Li, I don't think our domestic frame factories have the production capacity yet.

It seems that the strength is not enough, Zhao Guoyang then explained: Speaking of which, our Hongda Machinery Factory started from the frame, fuel tank and other iron parts. I still know a lot about the frame...

Li Kejian said Yes, nodded, and signaled Zhao Guoyang to continue.

Mr. Li, you should know that the welding of aluminum alloys is much more difficult than iron parts. The requirements for welding quality are also much higher.

In order to improve the welding quality, it is necessary to strictly control the welding fusion between parts with large differences in melting point, set the optimal gap, and select workers with excellent welding skills to operate...

Speaking of this, Zhao Guoyang couldn't help sighing: At least for now, our Hongda Machinery Factory does not have such a requirement.

Maybe he felt that what he said was too absolute, Zhao Guoyang added another sentence: Mr. Li, I'm not trying to spoil my own prestige by making others want me.

In fact, the level of welders in our factory is still acceptable, mainly because everyone is not familiar with the welding performance of aluminum alloy parts, and the difficulty of this operation is actually much greater...

After Zhao Guoyang's explanation, Li Kejian nodded silently, expressing his understanding.

In fact, what Zhao Guoyang did not say is that even if the welding process is barely achieved, few domestic frame manufacturers can complete the subsequent treatment of the aluminum oxide film.

In Zhao Guoyang's memory, after the aluminum alloy frame is welded, the treatment of the aluminum oxide film is also a key point.

If the aluminum oxide film cannot be kept bright, smooth and uniform, it will seriously affect the strength of the frame.

Zhao Guoyang's explanation made Li Kejian understand everything.

He said with a little regret: Guoyang, you are right, just like in the automobile industry, although the application of all-aluminum frame has begun to be popularized internationally, but our domestic independent automobile manufacturers have No one has mastered the technology yet...

Speaking of which, this is not a problem of your Hongda Machinery Factory at all, nor can it be solved by relying on Guoyang alone...

Seeing Mr. Li's gloomy expression, Zhao Guoyang felt a little uncomfortable.
