The main raw material for graphite crucibles is artificial graphite powder, which is also mixed with other materials; The formula of the crucible requires an insulated double axis stirring drum to mix all materials together in proportion; After mixing the materials, a paste barrel is needed to measure how much material is needed to press a crucible; The tested material requires a conveying device to transport the material into the mold and press it with a press; After pressing the crucible, it is demolded and dried before firing in the furnace.
Main features of our graphite:
1. uniformity of heating structure.
2. good electrical conductivity and high electrical load.
3. corrosion resistance.
4. inoxidizability.
5. high chemical purity.
6. high mechanical strength.

Shijiazhuang Nalai Biotechnology Co., Ltd Provide high quality Graphite electrode, Graphite electrode mainly petroleum
coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization,
machining, made of, can be divided into ordinary power, high power and high power, mainly used in steel smelting electric arc furnace and refining furnace smelting furnace, electric furnace steelmaking is the use of graphite electrode in furnace to import
he current, strong current in the lower electrode by gas arc discharge, use the heat generated by the arc for smelting.Graphite electrodes of different diameters are used according to the capacity of the electric furnace. For continuous use of the electrodes, the electrodes are connected by the threaded joint of the electrodes. The graphite electrode used in steelmaking accounts for about 70 ~ 80% of the total graphite electrode consumption.
