摘　　要：为解决LF冶炼钢水可浇性差,浇注水口结瘤以及连浇炉次少等问题,北营炼钢厂通过优化LF炉渣组分、降低熔点、提高流动性等方式,降低了钢水夹杂物含量,铸坯质量明显提高,提高了钢水纯净度以及连浇炉数,有效地降低了生产成本。In order to solve the problems of poor casting ability of molten steel in LF smelting,the clogging of sprue gate and the small number of continuous casting furnace,By optimizing the composition of LF slag,reducing melting point and improving flowability,the inclusion content of molten steel is reduced,the quality of slab is obviously improved,the purity of molten steel and the number of continuous casting furnace are improved,and the production cost is reduced effectively.

关 键 词：精炼渣 低熔点 流动性 夹杂物
