PRODUCT DESCRIPTION
Introduction:
Chrome Zircon Corundum Brick, 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.
Features:
l Strong resistance to glass liquid erosion
l Excellent thermal shock resistance
l Long service lifetime
Applications:
Chrome Zircon Corundum bricks are widely used in stacks and uptakes of glass fiber furnace; severe corrosion areas for colored glass furnace; sidewalls, tank bottom and fore hearths of thermal insulation fiber glass furnace; discharge hole of ceramic frit glaze kiln, metallurgic molten bath and rotary kiln; zinc oxide melting furnace, garbage destructors. The corrosion resistance of AZCS-50 is superior to that of AZCS-30; AZCS-60 provides superior corrosion resistance to AZCS-50. AZCS-15and AC-15 can also be used as superstructures and burner blocks for insulating fiber glass furnaces.
