近年来,南方各省中小型钢铁企业所使用矿石含铅(Pb)量显著上升,柳州、三明、韶关、广州、涟源、新余等钢铁厂的炼生铁产,均受其害.柳钢1号高炉在1979年12月19日因炉底严重损坏,被迫停炉大修.接着,2~#炉又于1980年3月10日因铅液从上渣口下方钢壳裂纹处漏出而被迫停炉抢修,生产时间不足三年,使全厂炼铁生产近半年处于半停顿状态.柳钢的事故,向炼铁工作者敲起警钟,促使大家对含铅矿石使用中的一些问题进行探讨.一、铅的理化性能
In recent years, the lead (Pb) content of ore used by small and medium-sized iron and steel enterprises in various provinces in the southern provinces has risen significantly, and the production of pig iron from Liuzhou, Sanming, Shaoguan, Guangzhou, Lianyuan and Xinyu, The blast furnace was severely damaged on December 19, 1979, and was forced to shut down for overhaul. Then furnaces 2 ~ # were forced to leach lead from the cracks on the steel below the upper slag mouth on March 10, 1980. Shutdown repair, production time less than three years, so that the entire factory production of iron and steel nearly half a year in a state of semi-stop Liuzhou Iron and Steel, the iron bell workers wake up alarm to urge everyone to explore some of the problems in the use of lead ore First, the physical and chemical properties of lead
