【Abstract】 Through the statistical analysis for the strands cast from 32Mn6 and 42MnCr52(v)in Tianjin Pipe Co. 1994,we found that there exists a certain relationship between the Al content and vertical cracks of these strands. Thus, the countermeasures were worked out, the vertical cracks reduced and qualified rate of the strands improved.更多还原
