3차원 FEM을 이용한 Angle과 Channel의 압연공정 및 Roll Stress 해석

AB100 & CB100 are general products in the steel beam of the section shape. They are applied for construction, welding and shipbuilding structures. But currently roll damages are generated in the intermediate & finish mills during producing AB100, CB100. The goal of this project is to conduct rolling & roll stress analysis using the 3D FEM program and to research the things which roll diameter affects roll stress. By the analysis results, it is determined that the recording roll stress where the roll diameter will be big comes to be small, and it is recognized that roll damage occurrences of finish rolling mills can be high by roll stress analysis results.
