· Internet of Vehicles technology is more common Internet intrusion in automotive manufacturing

In 2014, the Internet accelerated into various industries and dramatically changed our way of life. Cars are also unable to resist the invasion of the Internet, which can be seen from the many new car products on display at the just-concluded CES (International Consumer Electronics Show). Unlike traditional cars, even on a global scale, it is very new to build a car under the Internet mindset. Therefore, Chinese companies and traditional multinational companies can start to start together.
Internet of Vehicles technology is more common in the Internet of Things is not new, but in the past year, it has been widely popularized. However, compared with the generalized Internet of Vehicles (car and vehicle communication, etc.), the practical application of the Internet of Vehicles still stays on the Internet. stage.
Anjixing, a subsidiary of Shanghai GM, is currently the largest company in terms of in-vehicle interconnection in China. At the beginning of 2014, its number of users has exceeded 700,000. In 2015, Anjixing will take the lead in LTE 4G services in China, and the application of 4G high-speed network will provide various possibilities for building an interconnected ecosystem and intelligent transportation in the future.
In terms of the Internet of Vehicles, the innovation of the new brand Guanzhi Automobile is also very large, and the Yiyun system equipped on the Qiaozhi model incorporates more social functions. In the latest version of Guanzhi Yiyun 2.0, “go to TA” allows the owner to provide a shuttle service for WeChat friends, as long as the friends pass the Yiyun system to indicate their destination, GPS and network. The positioning function also provides an intuitive positioning indicator for walking friends and vehicles.
In addition to these in-vehicle entertainment communication systems, many Internet companies have infiltrated into the daily use of automobiles in the past year. For example, Tencent released Tencent Lubao last year. This is Tencent’s first driving companion app that focuses on driving safety and green travel. It provides driving behavior evaluation, fuel consumption assessment, real-time road conditions, intelligent route planning, fuel-efficient route recommendation, free voice navigation and other comprehensive travel services, while also adding social and other elements to meet more needs of users.
Traditional car companies embrace the Internet Unlike traditional industries such as banks that “resist” the Internet, traditional car companies are actively embracing the Internet, and some are holding hands with Internet companies to jointly develop future Internet cars.
In July last year, SAIC Group took the lead in announcing a strategic cooperation agreement with Alibaba Group for “Internet Car”. The two parties will actively cooperate in the field of Internet vehicles and related application services to jointly build a future-oriented Internet car and its ecosystem. At present, the two sides have set up a research and development team of hundreds of people. In the future, the Internet car will be built with the end user experience as the guide, fully integrating Alibaba Group's "yun OS" operating system, big data, Ali communication, high. Resources such as German navigation, Alibaba Cloud Computing, and Shrimp Music.
Xu Heyi, the chairman of BAIC Group, has repeatedly published the idea of ​​car interconnection in public. The company first learned from Baidu, and then came out with the news of cooperation with LeTV. The cooperation model between the two parties has not yet been announced, but only It is this way of cross-border cooperation that has attracted a lot of attention.
Although the Kaiye Automobile, which was newly born in the second half of last year, did not hold hands with Internet companies, it advocated using Internet thinking to build cars. Not only that, but it also adopted a foundry production model widely used in the IT field - not building its own factory, renting Other people's factories make cars.
IT companies make cars?
In stark contrast to the trend of Internetization in traditional car companies, traditional Internet companies have to be car-oriented. Perhaps it was the success of Tesla. In 2014, Xiaomi, LeTV, Foxconn and other Internet companies that had not been in contact with cars had to build cars.
There have been media reports that Xiaomi is about to enter new energy vehicles and build a Chinese version of Tesla. In December last year, LeTV founder Jia Yueting revealed the LeEco supercar “SEE plan” through a personal microblog, and copied the LeTV eco-vertical integration model to redefine the car. LeTV officially announced its entry into the automotive field. Soon after, LeTV announced that Lu Zhengyu, the former general manager of Infiniti China, officially joined. Foxconn, the world's largest foundry company, also announced at the end of last year that it would build a "flat price Tesla."
Regardless of whether these Internet companies make cars "infatuated by dreams," they will really change the world's auto industry. At least, they will bring different ways of thinking to the traditional auto industry.

Tungsten Carbide Roller

Tungsten carbide roller has characteristics of good wear resistance, high temperature red hardness, thermal fatigue resistance and thermal conductivity and high strength , have been widely used in high-speed wire rod, bar, rebar, seamless steel tubes, etc. Domestic production of tungsten carbide roller materials mostly WC- Co, WC- Co- Ni- Cr two series, and the content of Co, Co- Ni - Cr is in the range of 6wt% ~ 30wt%. From the use of perspective, tungsten carbide rollers has good mechanical properties, its flexural strength up to 2200 MPa or more, shock toughness up (4 ~ 6) × 10^6 J/ m^2, Rockwell hardness (HRA) is up to 78 to 90, widely in the high-speed wire rod rolling process, which is much higher than single-slot chilled cast steel or high speed steel rolls.Tungsten carbide is made of Tungsten Carbide Powder and binder phase (such as drilling, nickel, etc.), and then pressing and sintering, regardless of the conditions under cold rolled or hot rolled has excellent wear resistance, tungsten carbide rollers has been widely used in pre-finishing mill and finishing of high-speed wire rod currently. On the performance of tungsten carbide roller in hot-rolling wire rod , the material must meet the following requirements:
1. Sufficient anti-fracture strength;
2. Good abrasion resistance;
3. The smooth surface finish;
4. Excellent corrosion resistance, thermal fatigue, thermal cracking performance.
Tungsten carbide roller rings can working in bad conditions , small profile rolling (especially rebar rolling) process conditions is harsher than the high-speed wire rod, and therefore corresponds to the profile rolling ,tungsten carbide rollers recommend using high binder phase carbide.
