摘要
在LF精炼炉采用大渣量操作,使用Al粒脱氧,电石埋弧,控制萤石用量,控制精炼时间在25～35min等,达到少增C增Si的目的,日钢成功开发出冲压用热轧钢板SPHD,铸坯质量良好,中心疏松0.5级。
In order to control carburization and increasing silicon in LF refining, Rizhao Steel operated by large slag, deoxidized with Al ball, controlled the amount of fluorite, and controlled the refine time between 25 min and 35 min etc, developing SPHD successfully. The slab quality is good and central unsoundness is 0.5 grades.
