| Abstract: | In view of the problem of edge crack defects of low carbon steel seriously affected the normal rolling of the cold rolling production line,which has resulted in some damage to the economic benefits.The different macro- morphology characteristics of edge crack defects had been classified systematically.Meanwhile，through the whole process investigation on steelmaking，hot rolling and cold rolling procedure and micro means such as metallography，electron microscopy,the causes of different types of defects were also analyzed.With the suitable measures of consistent system being adopted，the edge crack of non- trimming rolled low carbon steel was controlled effectively，and the edge quality was improved obviously． |
