電熔莫來石是采用工業(yè)氧化鋁、高純度石英砂為主要原料，在電弧爐中熔煉而成，結(jié)晶體為針狀，它具有熱震穩(wěn)定性好，抗折強(qiáng)度大，荷重軟化溫度高，硬度大，高溫蠕變小等特點(diǎn)。被廣泛應(yīng)用于耐火材料、玻璃窯體爐襯磚、莫來石磚、大型冶煉高爐熱風(fēng)爐磚、高爐低蠕變硅線石磚、陶瓷窯具、匣缽、棚板、石油化工等行業(yè)。
Electrocast mullite is the used of industrial alumina, high-purity quartz sand as the main raw material, smelting in the electric arc furnace, of which the crystal is needle-like. It has good thermal shock stability, large flexural strength, high load softening temperature, large hardness, high temperature creep and so on. It is widely used in refractories, glass kiln lining brick, mullite stone brick, large-scale smelting blast furnace brick, blast furnace low creep silica wire stone brick, ceramic kiln, sager, girt strip, petrochemical and other industries.
