棒鋼・線材圧延3次元FEM解析システムの開発

抄録

A new user-friendly three-dimensional simulation system for bar and wire rod rolling processes has been developed. A graphical user interface specially designed for rolling engineers is coupled with strategic FE simulator for rolling process CORMILL. This simulation system enables them to make accurate prediction of load and deformation characteristics of bars and wires under rolling. The effects of roll profiles as well as cross-sectional temperature distributions to width spreads are validated by comparing numerical results obtained by this system and experimental measurement. After four years' developing project organized by ISIJ, this system is now being installed in bar and wire rod rolling industries. A new R&D activities in bar and wire rod rolling will be promoted as the developed system can be easily operated by rolling engineer without special knowledge for non-linear FEM.
