摘　　要：为了解管坯的洁净度水平,对衡钢炼钢分厂EAF→LF→HCC工艺生产的36Mn2V、37Mn5油管用水平连铸坯,通过采取示踪剂示踪、系统取样、综合分析等方法,对LF处理前后及中间包钢水和连铸坯中w(T.O)、显微夹杂及大型夹杂物的数量及变化情况进行了研究,并对夹杂物的产生原因进行了分析。研究结果表明,目前工艺条件下36Mn2V、37Mn5连铸坯的洁净度水平一般。In order to solve the quality of tube stock of 36Mn2V and 37Mn5 pipelines, which are processed through the processing route of EAF→LF→HCC in the Sleet-making Plant of Hengyang Steel the present paper studies the quantity and changes of w （T. O）, the micro inclusions and macro inclusions in the liquid steel in tundish and in the CC slabs prior to and post LF treatment by way of tracking the tracer, sampling and comprehensive analysis and analyzes the causes to formation of the inclusions. Results show that under the current process conditions the cleanliness of the CC slab of steel 36Mn2V and 37Mn5 still remains at an ordinary level.
