ABSTRACT

Tyre cord wires and steel saw wires represent typical precision pearlitic steel wire rods. Reducing the rate of wire breaking is one of the most concerning problems in metallurgy. This paper surveys the technical progress in the control of inclusions and central segregation in tyre cord steel wires and saw wire steel in the last 20 years, including the control of the [Al]s content in steel, selection of better refractories, deletion of the VD process, developing of new kinds of refining slag system, optimize the structure of tundish, control of Ti-containing inclusions, feeding steel trip into a mould, electromagnetic stirring technology, soft reduction technology at the solidification end of continuous casting slab, and the control of billet size. Finally, the unresolved issues that should be studied in the next 10 years have been formulated.

摘要

轮胎帘子线和钢锯线是典型的精密珠光体钢盘条。降低断线率是冶金行业最关心的问题之一。综述了近20年来帘子线钢丝和锯丝钢在控制夹杂物和中心偏析方面的技术进展，包括钢中[Al]s含量的控制、选用更好的耐火材料、去除VD工艺、新型精炼渣体系开发、中间包结构优化、含钛夹杂物控制、钢锭入模、电磁搅拌技术、连铸坯凝固端轻压下技术、钢坯尺寸的控制。最后，制定了未来10年应该研究的悬而未决的问题。
