On the podium, Antonio Ducati's speech had already begun.
The topic of his speech was the application and current situation of aluminum materials for motorcycles in the world.
"The characteristics of aluminum alloy, I think all the professionals here must be aware of everyone.
It has a variety of characteristics such as light weight, good texture and wide application. ” "At present, the application of aluminum alloy materials in large-displacement motorcycles above 125 has been very common.
However, compared with the use rate of other alloy materials in motorcycles, the application of aluminum alloy materials is still much inferior. ” "Today, I would like to discuss with you what kind of prospect aluminum alloy has in the motorcycle industry."
At the beginning of the speech, Antonio Ducati quickly introduced everyone into the topic with his own unique entry point.
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 alloy gradually became popular in the global motorcycle manufacturing industry.
Moreover, it is widely used in relatively high-end cruising cars, special vehicles and other models.
Judging from Zhao Guoyang's knowledge reserve beyond this era of twenty or thirty years, this Mr.
Antonio was able to vigorously advocate the use of aluminum alloy in the motorcycle industry in the early nineties, which can be regarded as a very advanced vision.
Li Kejian, who was on the side, caught a glimpse of Zhao Guoyang's approval, and couldn't help asking: "Why, Guoyang, for materials science, do you also have the characteristics of this aluminum alloy material, you are clear again?"
Hearing this, Zhao Guoyang's face was stunned.
Seeing the expectant gaze cast by Li Lao, he coughed lightly, touched his chin and said, "Li Lao, I only learned something in terms of materials science when I went to Shagang Group on a business trip before.
At most, I can only know a little bit about it."
When Li Kejian heard this, he seemed to remember something, so he said "hmm", "Shagang Group, I know this." ” "They Chairman Shen Zhirong is a figure, as long as he is in charge of planning, in the future, our domestic steelmaking industry will definitely have a place for their Shagang Group."
Zhao Guoyang recognized Li Lao's judgment very much, and nodded in agreement again and again.
"By the way, the new type of pressure casting of aluminum alloy that Antonio said just now, Shagang Group should also be able to do it," Li Kejian tilted his head and asked Zhao Guoyang casually.
"Well, it should be possible.
This material is currently commonly used in bicycles, using S35C welded body and A2107 integral forged pedals, and all aluminum alloy die-casting parts can be used. ” "In this way, in terms of construction cost, it should be possible to cut a large piece," Zhao Guoyang said casually.
What he didn't notice was that after he said this, a "old fox" smile appeared on the face of Li Lao next to him.
When the two were communicating in a low voice, Antonio Ducati on the stage had already talked about important places.
"As we all know, the use of aluminum alloy on the frame has the lowest proportion of all components.
So what I want to focus on today is this topic."
After Antonio's words came out, Li Qinan and Sun Zhengxiao in the back row looked at me and I looked at you, with a confused face.
After a while, Li Qinan reacted first and said: "Mr.
Sun, this Mr.
Antonio, is it talking nonsense, the frame is not using aluminum alloy, isn't it a blind toss, there is a need to discuss?"
Li Qinan's words are not untrue, motorcycle frames, the requirements for rigidity are very high.
The reason is simple, the frame is another important part of a motorcycle in addition to the core engine.
If the rigidity is too low, the frame will bend and deform due to the torque generated by the rear wheel force.
Affecting the rider's natural sense of handling is secondary, and if the deformation is serious, the car crash and death are possible.
Therefore, in the domestic motorcycle manufacturing industry, the frame is usually made of materials with high strength.
As a light material, aluminum alloy has indeed not been applied by any manufacturer in the frame.
Listening to Li Qinan's complaints, Sun Zhengxiao on the side also agreed with a solemn face.
Although they Jialing Group is currently considered by many industry insiders to be the leader of the domestic motorcycle industry, in the market's feedback to various enterprises, it is obvious that the frame of the Heavy Riding Group has been rated higher.
Therefore, in terms of body structure and frame, Sun Zhengxiao did not dare to call himself the "boss".
While the two of them were discussing in a whisper here, on the other side, Mr.
Kawasaki from Kawasaki Co., Ltd. was also whispering with his beautiful assistant Kiko Aso.
Mr.
Kawasaki squinted his eyes and sighed softly, "Kiko, this Mr.
Antonio, really dare to think about it."
"The application of aluminum alloy castings in motorcycle frames, although it has been around for a long time.
But there haven't been many successful examples."

Kiko Aso bowed slightly: "Hai, President Kawasaki As far as I know, the application of the all-aluminum frame should be on the road racing car Ducati 500 in 1979 at the earliest. ” "However, in order to avoid controversy at the time, the body of the car was painted black to hide the original appearance of the all-aluminum frame."
Kawasaki Yu sighed, nodded and smiled: "That's right, if they didn't do it at the beginning, I guess those racers wouldn't dare to drive this car, hehe" Kiko Aso smiled reservedly and continued, "Yes, president.
It wasn't until 1987 that Ducati made it public. ” "The aim, of course, is to prove that it is one step ahead in terms of aluminum frames" "Roar, that's right" Kawasaki Yulian nodded and said: "Since the launch of Harley's HD550 in '84 and Honda's RZV500 in '85, various manufacturers have been involved in the field of aluminum frames. ” Aso Kiko responded, and said with a slight smile: "Yes, Ducati's application in this area is indeed ahead of the industry, even BMW, Harley and other companies have to admit it."
"Hehe, even if they admit it, they won't say it" Kawasaki Yu smiled and waved his hand at Kiko Aso.
"Alright, let's move on.
Look at this Mr.
Antonio, what other amazing words to say" On the podium, Antonio was in high spirits, trumpeting the prospect of aluminum frame applications.
He raised his arm and said loudly: "As you know, the requirements of motorcycles for frames are nothing more than three aspects: first, good rigidity; the second is to reduce the weight as much as possible under the premise of achieving controllability; Third, it must be able to resist the strong vibrations of high-performance engines. ” Speaking of this, Antonio Ducati paused and jokingly said: "Of course, aesthetics must also be one of the requirements of the frame, even if I don't say this, everyone should understand." ” Listening to the emaciated Apennine man's teasing words, the audience just smiled.
Li Kejian, who has been listening carefully, couldn't help but ask Zhao Guoyang after listening to Mr.
Antonio's words: "Guoyang, what do you think about this aluminum alloy frame, do you think it is possible to achieve it in our domestic frame production?"
Zhao Guoyang was stunned for a moment, then shook his head and said: "Old Li, I think that for the time being, our domestic frame factory does not have such production capacity. ” It seems that the strength is not enough, Zhao Guoyang explained: "Speaking of which, our Hongda Machinery Factory started with iron devices such as frames and fuel tanks, and I still know a lot about the frame."
Li Kejian said "um", nodded, and motioned for Zhao Guoyang to continue.
"Mr.
Li, you should know that the welding of aluminum alloy is much more difficult than that of iron devices.
The requirements for welding quality should also be much higher. ” "In order to improve the quality of welding, it is necessary to strictly control the welding fusion between parts with large melting points, set the optimal clearance, and select workers with excellent welding skills to operate."
Speaking of this, Zhao Guoyang couldn't help but sigh and said: "Such a requirement, at least at present, we Hongda Machinery Factory does not have. ” may feel that what he said is too absolute, Zhao Guoyang added: "Old Li, I am not growing up others to destroy my prestige. ” "In fact, the level of welders in our factory is still okay, mainly in the welding performance of aluminum alloy parts, which we are not familiar with, and the difficulty of this operation is invisibly much greater."
After Zhao Guoyang's explanation, Li Kejian nodded silently to express his understanding.
In fact, what Zhao Guoyang did not say is that even if the welding process is barely reached, there are few domestic frame manufacturers that can complete the subsequent treatment of alumina film.
In Zhao Guoyang's memory, after the aluminum alloy frame is welded, the treatment of the alumina film is also a key.
If the alumina film is not kept bright, smooth and uniform, it will seriously affect the strength of the frame.
Zhao Guoyang's explanation made Li Kejian also understand it at all.
He said with a little abruptness: "Guoyang, you are right, just like in the automobile industry, although the application of all-aluminum frames has begun to be popularized internationally, but none of our domestic independent automobile manufacturers have been able to master this technology."
"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."
Looking at Li Lao's gloomy expression, Zhao Guoyang felt a little uncomfortable in his heart
