GRAPHITE BLOCK
Graphite blocks use high-quality petroleum coke as raw material and adopts advanced production technology and equipment. The products include: ordinary graphite, impregnated graphite, high-purity graphite, and fine-grain graphite. The product has the characteristics of high density, high compressive and flexural strength, low porosity, resistance to ablation, and resistance to acid and alkali. Widely used as metallurgical furnace, resistance furnace lining materials, graphite molds, graphite shaped parts materials.
