刚玉—莫来石棚板
刚玉—莫来石棚板:是以电熔刚玉、莫来石复合成型经高温烧结而成。
Corundum—Mullite Board: It is made by high sintering corundum and mullite together.
·优点:耐高温,抗腐蚀,荷重软化点高,适合在各种气氛条件下的高温炉中使用。
Advantage: Bear the heat, the anti- decay, refractoriness under load is high. It is suitable to be used in different high temperature kiln stove.
