China Silica Brick Refractory Fire Brick Manufacturer Price for Coke Oven Batteries, Find details about China Refractory Brick, Refractory from Silica Brick Refractory Fire Brick Manufacturer Price for Coke Oven Batteries
Silica brick is made of silica (≥96%)as raw material, added mineralizer and binder, produced by the process of mixing, molding, drying and firing. It has good performance of anti-acid slag and anti-erosion, high refractoriness under load temperature. Mainly applied in the carbonization chamber, combustion chamber, walls of coke oven, roof and walls of glass furnace, high temperature load-bearing part of hot blast stove, carbon baking furnace and other thermal kilns.
