(S067)Improvement on CC Technology of Auto Exposed Panel for Surface Defect Control -1Surface Defect Analysis

摘要

With the increasing demands of high high-grad grade automotive users, the e hot hot-dip galvanized sh sheets for automobile eets exposed panel with high surface quality is in urgent development. More attention has been paid to control the surfa surface defects caused by the CC process ce process, which are further interwoven with the defects formed in hot rolling, , cold rolling, a and hot nd hot-dip galvanizing processes. So, the defects caused by the CC process are difficult to be identified, judged and improved.
