STUDY OF RAISING TEMPERATURE OF MOLTEN STEEL IN CONVERTER WITH QUASI—GRAPHITE
-
摘要: 对转炉炼钢使用类石墨提温进行了研究,经150炉典型试验和扩大试验表明,类石墨提温剂提温效果显著,每吨类石墨提温剂可补偿温度40.7℃,且对造渣、去P、S无不利影响,完全能满足炼钢品种和溅渣护炉工艺的要求。Abstract: The raising temperature of molten steel in converter with quasi-graphite was investigated. The results obtained from 150 heats and expanded tests show the effect of raising temperature of molten steel with quasi-graphite is marked,the temperature compensation is 40.7℃ using 1 ton quasi-graphite.The use of quasi-graphite doesn’t influence slag formation and desulphurization and dephosphorization of molten steel during steelmaking process,can meet the requirements of steelmaking and slag splashing process.
