摘要
分析了SS400-B含硼热轧钢卷边裂产生的主要原因,介绍实施的降碳提钛降硼,减少炼钢和连铸过程吸氮,减小结晶器液面波动,调整连铸冷却制度,以及保证铸机设备状态等措施及其效果。
The main causes for edge crack of SS400-B hot-rolled strip were analyzed, the counter- measures such as to reduce carbon and boron contents while increasing titanium content, to decrease nitro- gen absorption during steelmaking and continuous casting, to reduce the mould liquid level fluctuation, to adjust continuous casting cooling system and to guarantee the caster status, and its effects were introduced.
