Analysis of crack tip stress of transversal crack on slab corner during vertical-horizontal rolling process by FEM

Journal Article


Abstract


  • Behavior of transversal crack notched on slab corner during vertical-horizontal rolling process was simulated by FEM. The crack tip stress in the whole rolling process was obtained. Influences of the friction coefficient, the initial crack size, the edger roll profile, and the groove fillet radii of grooved edger roll on crack tip stress were analyzed. For vertical rolling, the tension stress appears at crack tip near the slab top surface and the compression stress appears at crack tip near the slab side surface for the flat edger roll: however, the compression stress appears at crack tip near the slab top surface and the tension stress appears at crack tip near the slab side surface in the exit stage for the grooved edger roll. For horizontal rolling, the tension stress appears at crack tip just at the exit stage for the flat edger roll, and the tennion suess appears in whole rolling stagei the tension stress value near the slab side surface is much larger than that near the slab top surface for the grooved edger roll. © 2008 Central Iron and Steel Research Institute.
