Residual Stress Simulation and Generation Mechanism for Hot Strip Composite Roll during the Quenching

複合圧延ロールの焼入れ過程における 残留応力解析とその生成メカニズム

FEM simulation is performed during quenching process to investigate the generation mechanism and control the residual stress distribution for composite rolls. A large number of experimental data of shell and core materials are utilized for the wide range of temperature considering the quenching process. The results verify that initially the tensile stress appears at the roll surface but finally the compressive stress occurs. Furthermore, the effect of shell-core cross sectional ratio on the residual stress is considered. The results show that the residual stress only slightly increases with increasing the shell-core ratio.複合圧延ロールの焼入れ過程における残留応力においてFEM解析を行い,残留応力の生成メカニズムと応力分布について考察する.さらに,外層と内層の断面積の比である外内比が残留応力に及ぼす影響について考察を行い,外内比を大きくすることによる中心残留応力の増加は従来考えられていた程度より小さいことを明らかにする.
