剛玉-莫來石棚板
剛玉—莫來石棚板
剛玉—莫來石棚板:是以電熔剛玉、莫來石復合成型經(jīng)高溫燒結(jié)而成。
Corundum—Mullite Board: It is made by high sintering corundum and mullite together.
·優(yōu)點:耐高溫,抗腐蝕,荷重軟化點高,適合在各種氣氛條件下的高溫爐中使用。
Advantage: Bear the heat, the anti- decay, refractoriness under load is high. It is suitable to be used in different high temperature kiln stove.
