- 摘要:
- 某钢厂在生产冷轧板时,钢板表面出现大量线状缺陷,对缺陷位置进行成分分析,确定缺陷是由铸坯裂纹导致。为降低铸坯表面裂纹缺陷率,以降低钢板表面线状缺陷率为研究对象,使用ANSYS建立铸坯凝固模型,并进行二冷配水分析,对照冶金准则提出质量改进方案,降低缺陷发生率。经验证,采用改进方案,降低了钢板表面线状缺陷的发生率,有效提升了产品质量。A large number of defects appeared on the surface of cold-rolled steel sheet in a steel mill,the location of the defect was analyzed and the defect was determined to be caused by the slab crack.In order to reduce the defect rate of slab surface crack,the research object was to reduce the linear defect rate of steel plate surface.ANSYS software was used to establish the solidification model of casting billet,and secondary cooling water distribution analysis was carried out.It is proved that the improvement scheme can reduce the incidence of linear defects on the surface of steel plate and effectively improve the product quality.
