點擊圖片查看原圖電熔莫來石是一種人工合成的電熔制品，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。
電熔莫來石廣泛應(yīng)用于低蠕變熱風(fēng)爐轉(zhuǎn)，鐵水包及魚雷罐磚，高溫工業(yè)窯爐磚，玻璃窯襯磚及高溫匣缽、棚板等耐火制品。
Fused Mullite is a kind of artificially producedfusedproduct with acicular crystals, which has good thermalresistance,strong modulus of rupture, high refractoriness underload (RUL),high hardness, and good high-temperaturecreep-resistance.
Fused Mullite iswidely used in manufacturing manyrefractory products, like the lowcreep-rupture bricks for thehot-air stove, melting-iron groove ortorpedo car, high-temperatureindustrial kiln, glass meltingfurnace, as well as in producinghigh-temperature saggers or shedplanks, etc.
