帘线钢中氧化物夹杂控制技术在生产中的应用

Industrial application of control technology of oxide inclusions in tyre cord steel

摘要: 在帘线钢冶炼过程中,通过采用炉后弱脱氧、防止钢液污染,以及控制精炼顶渣碱度指数和Al₂O₃含量指数等措施,使钢中夹杂物向低熔点区域转变,促进钢中夹杂物上浮、排出钢液,同时也使钢中残留氧化物夹杂具有良好的变形性能.实践表明,通过采用上述工艺措施,帘线钢中夹杂物成分、尺寸和变形性得到了有效控制.

Abstract: In steel making for tyre cord, weak deoxidation, prevention of reoxidation, and control of ba-sicity and Al₂O₃ content in refining slag were adopted to decrease the melting point of inclusions in liquid steel and promote floating upward of inclusions. It was proved that the composition, size and deformation ability of inclusions in tyre cord were promoted by the application of the abovementioned technologies.
