摘要
介绍了热轧弹簧扁钢的生产工艺流程,分析了中、精轧机组孔型设计、进出口导卫设计的不合理和压下量过大等主要影响成品材宽度波动的因素,提出了相应对策。通过技术改进,小规格弹扁的成材率、合格率逐步提高。
The production process of hot-rolled flat spring steel is introduced, the main factors of influencing product width such as unreasonable of pass design in medium and finishing mill group and design of guide,excessive reduction amount are analysed, corresponding countermeasure are put forword. The rolling yield and qualified rate of small size flat spring steel are raised through technical improvement.
