Product Description

Product Show

Note the use of the crucible:    
   1. Check whether there are cracks in the graphite crucible before use.
2. After the use of dry place, avoid rain intrusion; before use to be slowly baked to 500 degrees C before use. 
3. Should be based on the capacity of the crucible feeding, avoid squeeze too tight, so as to avoid thermal expansion of metal cracking crucible.

Company Profile

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
