The sizing press process was developed to achieve extensive width reduction and yield improvement. The slab head and tail shapes after sizing pressing are important in crop loss reduction and stable operation. This study was carried out to investigate the deformation behavior of the slab head in sizing pressing with back pressure. Finite Element Analysis and a model experiment were conducted to study the deformation behaviors of the slab head thickness profile and plan-view pattern. It was found that width reduction by the back-pressure method enables control of the slab head shape. The maximum thickness of the central part of the slab head was reduced and the plan-view pattern changed from a fishtail shape to a tongue shape when back pressure was applied during sizing pressing.
