Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 94% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, thermal shock resistance is poor. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, refractory material, good thermal shock resistance, resistance to acid slag, widely used.
Henan Sialon Technology Company has R & D centers and two independent production plant: Sialon factory is located in Gongyi City, science and technology projects within the plant. A total investment of 500 million yuan, with an investment of 200 million yuan in the two world class advanced production line has been officially put into operation, the high-grade refractories with a full range of products the production of glass kiln. The factory is located in the town of stone refractory Heluo Gongyi City Industrial Zone, plant area of 4 production lines in the production of various high grade sintered materials, amorphous full series of full series. The main products are AZS33#, 36#, 41# casting and sintering of zirconia corundum brick, mullite, corundum mullite, corundum mullite bricks, lightweight alumina bubble brick, high alumina brick, low porosity, clay brick, brick clay and other unshaped refractory castable series, all products are widely used in glass, aluminum, steel, cement, petrochemical, building materials and other industries.
