Numerical analysis of transversal crack on slab corner in straightening during continuous casting
The transversal cracks might appear on slab corner positions during continuous casting, which severely affect the quality and quantity of products. The behavior of slab in the straightening period during continuous casting, and the stress distribution on slab surface and the change regularity of stress on slab corner were obtained by dominant kinetics finite element method, finally the influence of stress distribution on slab on the initiation of transversal cracks on slab corner was discussed. Results show that the tensile stress appears on slab surface of inner arc side when the slab passes through the stage 6-8 during continuous casting. The research results are good for guiding the production.
