HOW TO MAKE MOLDED GRAPHITE BLOCK
Molded graphite blocks in petroleum coke and pitch coke as raw material, using metallurgical equipment in broken and airflow pulverization equipment for crushing processing, and then with binder according to certain proportion with countercurrent high-speed kneading machine kneading.
kneading the paste after the need after rolling piece process, ground into a paste with universal mill powder, with pressure fluctuation pressure molding machine equipment, After molding, roasting, impregnation, graphitization and the finished product.
ADVANTAGES OF MOLDED GRAPHITE BLOCK
01
Molded graphite block has good electrical conductivity, high temperature resistance, corrosion resistance.
02
High purity, self-lubrication, thermal shock resistance, isotropy, easy to precision machining and other excellent characteristics.
