摘　　要：通过对HRB500E钢表面裂纹缺陷进行了宏观和微观分析,获得了表面缺陷的形成原因。分析结果表明,轧材裂纹和翘皮缺陷来源于铸坯缺陷,主要原因是由于卷渣造成的,同时结合现场的具体条件,提出了相应的工艺控制措施,从而更好地提高产品质量,有效地指导HRB500E及其他棒材产品的实际生产。In this paper,through macroscopic and microscopic analysis of the surface defects of HRB500E steel,the reasons for the formation of surface crack defects are obtained.The analysis results show that the cracks and surface upwarping;of the rolled material originate from the defects of the cast slab,which are mainly caused by slag entrapment.At the same time,based on the specific conditions of the site,the corresponding process control measures are proposed to better improve the product quality and effectively Guide the actual production of HRB500E and other bar products.
