Application of DEFORM-3D Finite Element Analysis in Optimization Design for Steel Rolling Production

Abstract

In this paper, DEFORM – 3D finite element analysis program is used as work platform, the high-speed wire rod rolling process of φ20 bar as the research object to be simulated numerically, using the method of ‘simulation—analysis—optimization’ to research . The first step work of the 12 rolling process is as an example to show the simulating process and results. The stress field, strain field are simulated in the process of high speed wire rod rolling .Through analysis, the defects of rolling technology were found out. Therefore, the optimum design is gotten and then simulated which improved the actual production process and avoided the original defects. So the optimum design is proved feasible in groove design and the optimization of process parameters in the production process. The paper is trying to find out the law of three-dimension metal flow in the rolling process of high-speed rod and summarize the regularity of the metal deformation. Some viewpoints are proposed about the correct pass design and the technical parameter of optimization in producing process.
