冷轧用低硅低硫铝镇静钢的LF精炼工艺改进

IMPROVEMENT OF LF REFINING PROCESS OF LOW-SILICON LOW-SULFUR ALUMINIUM KILLED STEEL FOR COLD-ROLLING

针对邯钢三炼钢厂冷轧用低硅低硫铝镇静钢LF炉精炼生产增硅严重的问题,对其限制性环节进行分析后,制定了新的LF精炼工艺,使供冷轧用料的钢水合格率明显提高。

Against the problem of silicon increased much more in refining production of low - silicon low - sulfur aluminium killed steel for cold - rolling with LF furnace in No. 3 Steelworks of Han Steel, its limited production steps are analyzed, new refining process worked out, and so the ratio of qualified melting steel obviously increased.
