简要介绍了奥氏体不锈钢连铸坯容易出现的几种表面缺陷,如凹陷、深振痕、渣坑、压坑(痕)等,并对表面缺陷进行了解剖分析,结果表明,凹陷、深振痕、渣坑下偶发伴随着裂纹缺陷;且渣坑下有孔洞缺陷,孔洞距表层约1~2 mm;压坑下无裂纹、孔洞缺陷。
Several surface defects prone to austenitic stainless steel slab, such as depression, deep vibration mark, slag pit, pressure pit (trace) and so on, are briefly introduced. An anatomical analysis of the surface defects is made. The results show that the depth of depression Vibration marks and slag pits accidentally accompanied by crack defects; and under the pit there are hole defects, the hole is about 1 ~ 2 mm from the surface layer; no cracks under the crater, hole defects.
