Are you in the heat of the northern hemisphere? Still in a corner of the southern hemisphere? No matter how! When you turn around, you will always rotate again! Then, it should always meet the studs on the car tires. After all, the studs will always appear in cold and humid areas. Tungsten carbide studs are mainly embedded in car tires to prevent the car from slipping on wet skating surfaces and have a very broad market in many European countries.

Graphene is a new kind of carbon material, which is closely packed with carbon atoms into a single two-dimensional honeycomb lattice structure. It is the basic unit of building the most commonly used solid lubricant - graphite. It has lower friction coefficient than graphite. It is a new kind of additive for self-lubricating antiwear coating.

In the process of preparation of tungsten products and elimination of waste products, a large number of secondary resources containing tungsten will be formed. Recovering tungsten from secondary resources will not only improve the quality of tungsten, but also realize resource recycling. At present, the recovery and utilization of tungsten slag is mainly divided into three parts: (1) recovering valuable metals; (2) using tungsten slag as mineral material to produce wear-resistant materials; (3) producing tungsten slag glass-ceramics.

At present, carbon fiber-based thermal insulation material is widely used in vacuum heat treatment furnace, cemented carbide sintering furnace, single crystal silicon drawing furnace and polycrystalline silicon ingot furnace. It has the advantages of small thermal conductivity, low thermal capacity, low density, small linear expansion coefficient, high temperature resistance, strong thermal shock resistance and strong chemical corrosion resistance.
