刚玉制品
Corundum proucts
本产品采用电熔刚玉砂、纯氧化铝细粉为主要原料，经机械成型，高温烧成等工序制成。制品具有耐高温、耐腐蚀、热震稳定性好等特点，适用于石化工业、大中型合成氨气化炉与造气炉及轧钢加热炉底、出钢槽、各种高温电炉、钼钨丝高温炉、陶瓷煅烧炉、氧化铝瓷烧结炉等，也可作高温中的辅助材料，如匣钵、窑车砖等。
With fused white corundum aggregate and a-alumina fine as main raw materials, through mechanical mold and high temperature sintered , these products have high refractoriness . Good corrosion resistance ,antioxidation and thermal shock resistance. They are suitable for petro-chemical industry (like large and medium sized synthetic ammonia vaporization furnace and gasometry ) and metallurgical industry (for example , the bottom of roll steel heating furnace , steel spout , various kinds of high temperature furnace and ceramic sintered furnace) . Also can be used as auxiliary material in high temperature industry like kiln furniture like pusher.

粉煤灰陶粒耐火隔热窑衬砖
Clal duxt ceramisite insulating bricks
本产品是以粉煤灰陶粒为主要原料制成的一种新型窑衬材料。他具有容量轻、保温性能好的特点，是替代水泥窑用传统耐火材料的新产品，有较好的节能效果。主要用于水泥回转窑或立波尔窑的预热带和分解带（作为窑衬），也可用于其他类型高温窑炉、铸件、冒口、烟囱等高温隔热设施等部位。
This product is a new kind of kiln lining materials made with coal dust ceramisite.They have low density,good heat insulating properties,can be used to substitute the traditional refractories in cement kiln-Their main appliaction are preheating zone and decomposing zone of cement rotary kiln, also can be used in other heat insulating places for high temperature furnaces,funnels etc.
