In modern society, graphite products industry plays a very important role in our life and development. There are a lot of industrial sectors (such as mechanical and electrical, automotive, home appliances light industry, electrical instrumentation, communications, ordnance, etc.) to rely on the development of the mold industry technology improvement and development, the world has invested

Many advantages of graphite: (1) Faster processing speed: Usually, graphite can be machined faster than copper $number times; and the discharge processing speed than copper fast $number times material is more difficult to deform: The thin rib electrode processing advantage is obvious; the softening point of copper is about 1000 degrees, it is easy to

Graphite Crucible, because of its high temperature resistance, small thermal expansion coefficient, against thermal shock has a certain resistance to strain performance, acid, alkaline solution of strong corrosion resistance, with excellent chemical corrosion stability, so in the metallurgical, foundry, mechanical, chemical and other industrial sectors, is widely used in alloy tool steel smelting and non-ferrous

The advantages and disadvantages of graphite as a reactor material are as follows: (1) The graphite has a high scattering cross-section and a very low thermal neutron absorption cross-section, the higher scattering cross-section is used to slow the neutron, and the lower absorption section prevents the neutron from being absorbed, allowing the nuclear reactor to

At present, the problems of graphite industry in China are outstanding, the resource waste is very serious, the basic carbon content of hidden crystalline graphite is more than 70%, when coal is burnt out, most of the remainder is low-grade ore; flake graphite deep processing ratio and level is still very low, most of them
