【正文】 and ASC castable with AMC brick used for ladle and ASC castable used for iron runner system.3 ProspectUsed refractories can reduce the cost of raw material for refractories and metallurgy auxiliary material. The reuse ratio on of used refractories is very low in Bao steel at present。 but Ramp。D has been carried out. Pattern of reuse and repoducing on used refractories is diversification, i. e. consumer uses directly, refractories plant reclaimes, building professional plant reclaiming used refractories and they unite. The key t o success is developing and researching high technology on reuse and reproduction of used refractories. Reuse and reproduction of used refractories is also a contribution on environment protection, and so, reuse and reproduction of used refractories increases rapidly. Trend of zero discard has been indicated. 用后耐火材料的再生利用綜述了國內(nèi)外對用后耐火材料的再利用情況和發(fā)展趨勢，報導了寶鋼對用后鎂碳磚、鋁鎂碳磚、鐵溝料和鎂鉻磚等的再利用研究成果。再生耐火材料的性能接近或達到新產(chǎn)品的水平，甚至有些能達到優(yōu)質(zhì)耐火材料的水平。扼要介紹了用后耐火材料再生利用的設(shè)想。1 簡介大約九百萬噸的耐火材料消耗在中國每年快速發(fā)展的冶金行業(yè)，而不可避免的產(chǎn)生大約四百萬噸的廢舊耐火材料，而只有一少部分是作為耐火材料的原材料循環(huán)利用的。用后耐火材料的摒棄不僅是國家自然資源的巨大浪費,而且也是對環(huán)境的污染,不能用的耐火材料危害包括以下的幾種：1）垃圾；2）產(chǎn)生的二氧化硅粉塵引起塵肺??；3）產(chǎn)生放射性的氧化鋯原料；4）產(chǎn)生毒害性的鉻離子；5
