Wow! Did you hear that? The momentum of the Chinese is really getting bigger and bigger! Foreigners are starting to be afraid of us! Why? Because we Chinese are too hard! No matter what kind of high-tech it is, as long as we master it, we can definitely do better than them, and we can sell it to their hometown!
Imagine how fierce foreigners blew in those years, saying what "the jewel in the crown of industry", saying that four countries in the world have mastered high-speed rail wheel technology, France, Japan, Italy, and Germany. In order to protect technology, they adhere to the principle of three noes, do not apply for patents, do not publish, do not accept exchanges, and the degree of secrecy is higher than that of the atomic bomb and hydrogen bomb! China can only buy their finished products, and it is absolutely not possible to import technology!
But what about now? China's high-speed rail wheels are not only the first domestic market, but also exported to South Korea, India, and even Germany! Think about it, Germany is the home of high-speed rail wheels! This is equivalent to selling coal to Shanxi, you say how good my coal is!
Don't look at the small wheels of the high-speed rail, in fact, the difficulty is not low! A pair of wheels has to carry 17 tons and run at a speed of 250-350 kilometers per hour! If there is a little impurity, it will cause a catastrophe! In 1998, a train derailed in Germany, killing 101 people and injuring 105 others! The investigation results showed that the cause of the accident was metal fatigue in the wheels of a high-speed railway, which caused a small notch, which eventually caused the wheels to fall off! This is the strict requirement of high-speed rail wheel technology!
And the high-speed rail wheel is still a consumable! Every 1.2 million kilometers of operation must be returned to the factory for maintenance, and every 2.4 million kilometers of operation must be forcibly replaced! This is no joke! Therefore, the business of high-speed rail wheels will always exist, but there are few competitors, this is a "** business"!
At the beginning, when we introduced high-speed rail in China, the wheels of high-speed rail were imported from foreign countries! But we never give up! China's Zhibo company planned to cooperate with the German BVV, but it was not negotiated, and finally it cooperated with the Italian Luqini to establish the Zhiqi company! But the Italian company does not agree to technology transfer and low-price sales, so this joint venture is really just an Italian foundry! The key technologies are all kept by the Italians themselves!
But we Chinese are never discouraged! Masteel and Taizhong are both developing high-speed rail wheels! Their high-speed rail wheels are significantly superior to their imported counterparts! In 2013, the domestic D1 wheels were successfully tested in CJ1 EMUs and put into operation on the line with a speed of 250 kilometers per hour! In 2015, the domestic D2 wheels were assembled in the CR400 series "Blue Dolphin" and "Golden Phoenix" EMUs! In 2024, the G364 Fuxing, which is equipped with domestic high-speed rail wheels, will leave Tianjin Station! Chinese either don't do it, do it and do it best!
The benefits of localization are not only strategic, but also people's livelihood! Get rid of the stuck neck abroad, ** cheaper, and create more jobs! China's high-speed rail wheels are not only in China, but also exported to South Korea, India and Germany! This is the strength of the Chinese! Get the world to watch!
