2,Product Description:
Brief introduction:Low porosity schamotte brick is a high-quality clay brick, which is made of high quality calcined burnt gem, high-quality Calcined Bauxite or sillimanite powder, and high-quality clay fine powder. After scientific and reasonable proportion, the clay brick is formed by press with a pressure machine of 630ton or more. The firing temperature is 1380-1450℃, the Fe2O3 content of this product is low, the porosity is low, the strength is high, the gas flow erosion resistance and slag erosion performance is good, It has good stability performance in thermal shock resistance, and has been widely used in glass furnace heat storage room, ladle, dry quenching coke oven, petrochemical industry furnace, etc.
