具有工业意义的转炉溅渣护炉技术是1991年由美国LTY钢铁公司开发的。它是在转炉出钢之后留下部分终渣,加入适量调渣剂,然后用氧枪喷氮气,使炉渣溅到炉衬上达到护炉的目的。这种方法具有炉龄长、生产率高、节省耐火材料、操作简便和投资少等优点。 LTY钢公司印第安纳哈伯厂的转炉炉龄采用溅渣护炉之后炉龄由800炉提高到1995年的15658次(1996年达到19000次)。耐火材料消耗由1.2kg/t钢降低于0.38kg/t钢,转炉利用率由78％提高到97％,每年的检修时间只有11天。这三项指标都是世界纪录。美国的内陆、美钢联、阿姆科,国家钢铁公司等单位的转炉炉龄达到10000～15000次范围内。这项技术在美国十几个钢厂应用都取得了良好效果。现在加拿大、西欧、南美、南 Industrial slag splashing slag converter technology was developed in 1991 by the United States LTY Steel Company. It is left in the converter tapping after the final slag, add the amount of slag preparation agent, and then use lance nitrogen spray, the slag splashing to the lining to achieve the purpose of protecting the furnace. This method has the advantages of long furnace age, high productivity, saving refractory material, simple operation and less investment. Furnace age at LTY Steel’s Indiana Habo facility was increased from 800 furnaces to 15,658 furnaces in 1995 (up to 19,000 in 1996) with slag splashing. Refractory consumption decreased from 1.2kg / t steel to 0.38kg / t steel, converter utilization increased from 78% to 97%, the annual maintenance time of only 11 days. All three indicators are world records. United States inland, the United Steel, Amco, the National Iron and Steel Company and other units of the converter furnace reached 10,000 to 15,000 times the range. This technology has achieved good results in more than a dozen steel mills in the United States. Now Canada, Western Europe, South America, South
