新型冶炼脱磷技术——转炉预处理单渣法目前,转炉炼钢常见的脱磷技术有:转炉大渣量脱磷、双渣脱磷、转炉双联脱磷及转炉预脱磷等,这些技术在生产中取得了良好的脱磷效果,其中双渣法脱磷率高达90%左右。这些技术一方面使生产低磷钢及超低磷钢成为可能,另一方面又存在着转炉热量
New smelting dephosphorization technology - converter pretreatment slag method At present, the common dephosphorization technology in converter steelmaking are: dephosphorization of converter slag, dephosphorization of double slag, double dephosphorization of converter and pre-dephosphorization of converter, etc. Technology in production has made a good dephosphorization, which double slag dephosphorization rate as high as 90%. On the one hand, these technologies make it possible to produce low phosphorus steel and ultra low phosphorus steel, on the other hand,
