冷轧薄板的表面缺陷可分为易发现并能消除的和不易发现也难以消除的两类。如压痕和划伤之类缺陷只要认真贯彻规程,加强生产管理和操作人员的责任心,就不难发现和消除;但对擦伤、黑带和粘结之类的表面缺陷就不然了,这也是我们所要研究与探讨的课题。 Cold-rolled sheet surface defects can be easily found and can be eliminated and difficult to find and difficult to eliminate the two categories. Defects such as indentations and scratches are not hard to detect and eliminate as long as they conscientiously implement the rules and reinforce the sense of responsibility of production management and operators. However, surface defects such as abrasions, black bands and bonds are not the case, This is also the subject of our research and discussion.
