Duplex STS 후판 압연시 발생하는 상향 벤딩 해석

다국어 초록 (Multilingual Abstract)

Because of the significant increase in Ni price recently, the duplex stainless steels have received more attention to substitute for the expensive austenitic stainless steels. The advantages of using duplex stainless steel are well proven and its cost efficiency is undisputable. For that reason many stainless steel manufacturers have tried to produce a variety of duplex grades and sizes; However, due to upward and downward bending on front end of slab during plate rolling, most manufacturers have problems to progress next rolling pass. In this study, we performed FEM analysis for calculating the amount of slab bending by changing rolling reduction and initial height of slab. And finally we proposed better rolling pass schedule for reducing the upward bending of slab.
