摘　　要：论述了马钢CSP流程采用RH-LF双联精炼工艺生产超低硫、超低碳洁净钢水的工艺优化和深脱硫条件下的增碳、增氮控制技术。实际生产表明,用RH-LF双联法的CSP流程开发的DDQ-IF钢工艺可以满足批量生产的要求,CSP连浇炉数最高达到12炉,冷轧产品质量满足深冲板的要求。The necessity of utilizing RH-LF refining to produce ultra low sulfur and ULC steel for CSP line and controlling carbon and nitrogen content during deep desulfurization is described. The mass production of DDQ-IF steel in such a way can be realized with a maximum sequence casting heats of 12, with satisfactory quality of final products.
