| Abstract: | In this paper, the influence of various operating factors on the surface longitudinal cracks of slab is discussed basing on actual productive data, such as depth of the SEN, chemical composition,mold powder, heat transfer in mold, secondary cooling intensity , casting speed and superheat of molten steel in tundish. The way to eliminate the slab surface longitudinal crack is also introduced. |
