| Abstract: | First,defintion and classification of internal cracks are introduced.Afterwards,the general laws between deformation of cross section of coagulating shell and stress and internal cracks in the continuous casting steel slab are analysed.Finally,inadeguacies in standard YB/T 4003-1991 in effect are indicated.Meanwhile,the influence factors on internal cracks are summarized. |
