摘要
针对冷镦钢SWRCH35K盘条开裂情况,通过对冶炼、轧制等生产工艺和产品质量进行跟踪,同时采用盘条表面酸洗及金相检验等手段对开裂盘条进行了宏观和金相组织观察,分析出连铸坯表面存在角部裂纹是造成开裂的主要因素,并提出了减少盘条表面裂纹的解决措施。
Because of the circumstance that SWRCH35K steel wire rod cracking of cold heading steel occurred,we did the tracking of quality,smelting,rolling and the other production processes,at the same time,we did acid pickling and metallographic testing and the other manners on wire strip surface,we also did the observation on macroscopic and metallographic organization of cracking steel wire rod,therefore,we analyzed the major reason of cracking is corner cracking occurred on the surface of continuous casting billet,and we proposed the resolutions for decreasing the surface cracking of steel wire rod.
