摘　　要：介绍了本溪钢铁集团公司炼钢厂薄板坯连铸机浇铸的超低碳钢钢水的冶炼与精炼操作实践。对不同的精炼工艺路线进行对比后,优化选择了LF+RH精炼工艺路线,稳定地控制了钢中的C、N、Si等难控元素,大幅减少了钢水二次氧化现象,提高了钢水的纯净度和可浇铸性,且可实现多炉连浇。The smelting and refining practice of ULC Steel for thin slab casting at BenXi Iron ＆ Steel （Group） Co. , Ltd is introduced.. By comparing different refining process ways , an optimized refining way of LF ＋ RH is put forward, thereby, some elements difficult to control such as C.N.Si etc. can be controlled stably, re-oxidation phenomena in liquid steel decreased greatly, the cleanliness and castability of liquid steel improved , and continous casting with more heats realized.
