Chrome-Corundum Purging Plug
Chrome corundum brick is adopts corundum and fused chromium oxide as raw material, by adding micro powder and other additives, after mixing, shaping, drying, sintering at high temperature in shuttle kiln.
The quality of chrome corundum brick has reached or exceeded the level of similar products at home and abroad.
The Chrome Corundum Brick, the composite of Al2O3, Cr2O3 and ZrO2, is of the features of high bulk density, erosion resistance, and acid/alkaline corrosion resistance. Compared with corundum firebrick, the Chrome-Corundum Brick owns higher refractoriness and melting point, better thermal shock resistance and corrosion resistance, etc.
Due to its good chemical stability, high fire resistance, big intensity and good high temperature performance, it is a new top-grade refractory material with high erosion resistant. It is widely used for liner of high-temperature kilns required for steel, building material, non-ferrous smelt industry, light industry and chemical industry.
The Chrome Corundum Brick could be used at the firing section, throat section, reaction section, quenching section of carbon black furnace, garbage incinerator, etc.
