【摘要】 叙述了K60冶炼所采用的工艺路线。K系列管线钢技术要求高,其抗拉强度和塑性均高于X70要求,磷、硫目标含量要求低。截至2007年7月首秦管线钢冶炼设备主要有铁水脱硫与处理、100 t顶底复吹转炉与LF精炼,在没有真空RH精炼设备的情况下,成功地供货钢板5500 t。针对该厂投产时间短,脱磷、脱硫效率低的问题,采用了转炉双渣脱磷、LF快速深脱硫工艺,最终达到了大批量生产K60的能力。更多还原

【Abstract】 The article introduces the steel making technology line of K60.K series pipeline have strict technical requirements, K60 have higher tensile strength and ductility than X70.K60 steel was required low phosphorus and sulphur.Until July 2007 Shouqin’s steel smelting equipment have desulphurization pretreatment of hot metal,100 tons of top-bottom combined blowing converter and 100 t LF.In the absence of RH vacuum refining equipment,Shouqin successful delivered 5500 tons of plate.Aimed at the plant put into production for a short time,and the plant have low efficiency with dephosphorization and desulfurization.Shouqin adopted converter double slag process dephosphorization and rapid deep desulphurization. Finally Shouqin have the capacity of mass production of K60.更多还原
