摘要
介绍了热轧弹簧扁钢生产过程中所产生的质量缺陷,并对其进行了原因分析。通过选择合理的工装设备、加热制度、轧制工艺、剪切制度及缓冷制度,弹簧扁钢的质量问题得到有效解决。脱碳层深度、硬度、弯曲度都达到标准要求,表面划线、剪切毛刺及崩口未再产生,产品合格率达100%,完全符合用户需求。
The quality defects in the production of hot-rolled spring flat steel are introduced,and the causes are analyzed.The quality problems is effectively solved by selecting reasonable tooling equipment,heating system,rolling process,shearing system and slow cooling system.The decarburization layer depth,hardness and curvature meet the standard requirements,and the surface scribing,shearing burr and chipping are not produced again.The qualified rate of the product reaches 100%,which fully meets the user's requirements.
