Aiming at the slab wedge problem of a 2 050 mm hot rolling mill,a thermal mechanical coupled three-dimensional finite ele-ment model of a four-high roughing rolling mill is established by Abaqus.The relationship between the slab transverse temperature difference,center line offset and the slab wedge after rolling is studied,and the rule of slab wedge after rolling is obtained.Combined with the finite element simulation results,a roughing rolling gap leveling model considering the slab transverse temperature difference and center line offset is established.Through offline and online verification of the established model,it can be seen that the model has a good effect on relieving the wedge defect of roughing rolling slab,and can effectively guide the production.
