Optimization Design on Slab Chamfered-Mold Taper by Using FEM
ShouGang Research Institute of Technology, Beijing 100043, China
In order to solve the gap appears frequently on chamfer slab in the chamfered position and resulting in slab crack problems, the thermo-mechanical coupled solidification process in the slab chamfered-mold of molten steelhas been mathematical simulated by using the commercial finite element software ANSYS. The slab shell shrinkage and deformation can’t be made up effectively by putting to use traditional single taper mold. The taper in the upper mold is small particularly by adopted 0.9% ~ 1.2%/m, the corner gap grows is difficult to be restrained, and the shell growth in the corners is blocked.According to the calculation results of the model, chamfered-mold narrow taper is gradual, roughly simplified into two sections: the first section is the distance 0.35m from near the meniscus, the larger taper has been adopted and average taper is 2.16%; The second section is distance 0.35m from the meniscus to the mold exit, the smaller taper has been adopted and average taper is1.31%.
