【正文】 3 前景用后耐火材料的再利用可以降低原材料的成本和降低冶金工業(yè)耐火材料的輔助材料。 cm 3)顯氣孔率/%3232熱震穩(wěn)定性/M Pa13121312加用后鎂碳磚的比例/%97978080使用再生的鎂碳磚的三百噸的鋼包渣線的壽命從二十爐延長(zhǎng)到八十二爐，因此再生鎂碳磚的達(dá)到了原來的性能。2 用后耐火材料在中國(guó)的現(xiàn)狀寶鋼注重用后耐火材料的循環(huán)再生利用，他們使用用后的耐火材料，這樣可以降低成本、提高效益、保護(hù)環(huán)境和推進(jìn)事業(yè)水平。扼要介紹了用后耐火材料再生利用的設(shè)想。 cm 3)Apparent porosity/%Cold crush strength /M PaAdded ratio of magnesiachrome brick used /%70Baosteel developed used magnesiachrome brick for RH before 10 years, 20% used magnesia2 chrome brick was added into gunning mix for RH, and achieved favorable service result. Reproducing magnesia chrome brick is researched recently. Experimental result is shown in table 2. We have studied on AMC brick 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。 6) pollutant from volatile and the rmal deposed substance of pitch and resin. Used refractories can be even processed into rawmaterials with high price, performing as high–quality
