半石墨化自焙炭块—陶瓷砌体复合护衬技术先后在鞍钢7号(2580m~3)、4号(1002m~3)及2号(888m~3)高炉应用,这种复合炉衬兼有美国UCAR热压成型炭砖和法国“陶瓷杯”炉衬的优点,而且投资省,施工简便,所有筑炉材料可以全部国产化。近两年的生产实践表明,这种复合炉衬具有明显的节能效果,并改善了炉缸的工作条件,维持较高的炉缸温度,铁水温度提高了10～18℃,生铁质量提高。同时降低了炉前劳动强度。
Semi-graphitized self-baking carbon block - ceramic masonry composite lining technology has Anshan Iron and Steel No. 7 (2580m ~ 3), No. 4 (1002m ~ 3) and No. 2 (888m ~ 3) blast furnace application, The United States UCAR thermoforming charcoal and French “ceramic cup” lining the advantages, and investment in the province, the construction is simple, all the building materials can be all localized. The past two years of production practice shows that the composite lining has obvious energy-saving effect, and improve the working conditions of the hearth to maintain a high hearth temperature, hot metal temperature increased by 10 ~ 18 ℃, pig iron quality. At the same time reduce the furnace labor intensity.
