大规格冷镦钢线材的生产实践

分析冷镦钢线材冷镦开裂原因,针对Φ16,20 mm大规格冷镦钢线材出现的冷镦开裂、堆钢、不易集卷、尺寸超差等问题,从炼钢、连铸、轧制等工艺过程控制方面提出优化措施并付诸实践,有效地降低了生产事故,稳定了生产,减少了冷镦开裂。

Production Practice of Large Spec Cold Heading Steel Wire Rod

To analyze the cause of cold heading crazing of cold heading wire rod.Aiming at the problems such as cold heading cracking,stacking,difficult coil collecting and dimensional over-tolerance of 16,20mm large spec cold heading wire rod production process,the optimization measures are put forward from the aspects of technical process control such as steel making,continuous casting and rolling,and the measures are put into action.The production accident is reduced effectively.The production process is steady.The cold heading cracking is decreased.
