摘要
高速线材表面易出现结疤缺陷,从炼钢和轧钢两方面进行了分析,炼钢造成的结疤主要有点状结疤、翘皮状有根结疤、块状无根结疤、锯齿状结疤;轧钢造成的结疤主要有锯齿状结疤、块状结疤、周期性块状结疤。介绍各类结疤的外观形貌和金相组织。通过分析结疤原因及采取解决措施,为减少结疤缺陷提供理论依据。
Scab defect is easy to appear on surface of high speed wire rod.The reason of scab defect is analyzed from steel making and steel rolling,scab caused by steel making mainly includes:point like scab,warping-like root scab,massive non-root scab and sawtooth-like scab.The scab caused by rolling steel mainly has serrated scab,lumpy scab,periodic lumpy scab.The appearance and microstructure of all kinds of scabs are introduced.Through reason analysis of scab and adoption of measures to reduce scab defects to provide theoretical basis.
