Abstract: The purpose of this article is how to eliminate slab cambering at a slab sizing press in the hot rolling steel production line in some Chinese steel plants. A finite element:model of slab sizing pressing was established with the finite element software LS-DYNA. Slab cambering was analyzed aL different slab center-line offsets and asymmetrical hammerhead inclination angles. It is found that slab center-line offset is the main influence factor of slab cambering during slab sizing pressing, and then a quantitative expression of influence was gained.
