サイジングプレス幅圧下時背圧のスラブ端部形状に与える影響

抄録

The sizing press process has been developed to achieve extensive width reduction and improvement of the yield rate. 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 slab heads upon 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 a plan view pattern. It was found that width reduction by the back-pressure method can enable the 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 by applying back pressure during sizing pressing.
