Corundum mullite brick for sale in Sunrise refractory

Corundum brick is a refractory product with a content of alumina greater than 90% and a corundum-based crystal phase. The normal temperature compressive strength can reach 340MPa. The load softening start temperature can reach more than 1700 °C. Good chemical stability, strong resistance to acidic or alkaline slag, metal and glass. The thermal shock stability is related to its structure, and the corrosion resistance of the compact product is good, but the thermal shock stability is poor. Corundum bricks are widely used in various high-temperature kiln linings and kiln furniture in cracking, reforming furnaces and metallurgical industries in the petrochemical and fertilizer industries. The corundum mullite brick products produced by Zhengzhou sunrise Refractory Co., Ltd. adopt imported slab corundum and high-purity fused corundum as the main raw materials, and apply advanced ultrafine powder adding technology. After mixing, forming and drying, in the shuttle kiln It is fired at high temperature. High-quality high-purity corundum brick has the characteristics of high refractoriness, good thermal shock resistance, high temperature strength, excellent corrosion resistance, strong slag resistance, small expansion coefficient, low creep and anti-flaking, and is suitable for various atmospheric conditions. High-temperature kiln is used; high-quality high-purity corundum brick is widely used in high-temperature sintering of zirconia ceramics, fluorescent materials, electronic ceramics, magnetic materials, ceramic powders, petrochemical industry gasifier, synthetic ammonia two-stage reformer, carbon black reaction Furnace and glass industry high temperature furnace and other equipment. The appearance size, physical and chemical indicators and service life of the products have reached or exceeded the level of similar products at home and abroad.
