近几年冷轧带钢的质量异议绝大多数都是表面缺陷问题,冷轧带钢表面缺陷形态千变万化,产生原因错综复杂。炼钢、热轧、冷轧之间各工序都可直接或间接造成裂纹或类似裂纹缺陷的产生。本文对唐山建龙实业有限公司冷轧厂低碳铝镇静钢的裂纹缺陷进行了较为全面的分析。笔者认为各工序只有正确识别各种缺陷,加强对缺陷的检测和分析,找到问题的根源,采取相应的措施,才能改善产品质量。
In recent years, most of the quality problems of cold-rolled strip are surface defects. The surface defects of cold-rolled strip vary in variety and cause for complicated reasons. Steelmaking, hot rolling, cold-rolled between the processes can be directly or indirectly caused by cracks or similar crack defects. In this paper, Tangshan Jianlong Industrial Co., Ltd. cold-rolled low carbon aluminum killed steel crack defects a more comprehensive analysis. I believe that the process is only correct identification of various defects, to enhance the detection and analysis of defects to find the root cause of the problem, to take appropriate measures to improve product quality.
