摘要
鞍钢采用铁水脱硫处理、转炉吹炼、炉外精炼、VD真空处理、大方坯连铸、热送连轧和线材轧制生产出钢帘线线材。线材中Al2O3、Ti(C,N)等脆性夹杂物粒度<5μm,塑性夹杂物的宽度≤15μm。钢的化学成分控制在狭窄的范围内,铸坯的偏析轻微。不同炉次、批次的帘线钢线材的力学性能相差很小。线材的脱碳层深度、网状碳化物、氧化皮脱落等项目符合检验标准。经用户试用符合生产钢帘线的要求,已转入批量生产、供应。
Angang New Steel Co. , Ltd. produces tire cord steel wire with hot metal desulphurization, converter steelmaking, LF and VD treatments, bloom casting and hot charge rolling. The size of brittle inclusions in the wire such as Al2O3 and Ti（C,N） and so on is less than 5 μm. The width of plastic inclusions is less than 15 μm. The composition of liquid steel is controlled in a narrow range. Sampling inspection proves segregation in bloom is slight. Wires from different heats have uniform properties. The indexes of decarburization depth, distribution of cementite along grain boundaries and scaling are in accordance with specification. Customer tryout proves tire cord steel wire meets their requirements, and the tire cord steel wire has been put into mass production.
