GROUP FEM MODEL AND APPLICATION FOR TUBE SHAPE PREDICTION IN STRETCH REDUCING PROCESS
Aimed to the problem of tube shape for multi-stand stretch reducing unit of seamless tube, the stretch reducing process was divided into the rolling deformation on the stand and remeshing generation between the stands. The group finite element model of tube shape quick-prediction has been established to research the wall thickness and the diameter on the platform of FEM software Marc. The simulated tube shape was analyzed according to the product rolling technical of certain company. The reliability of the model was verified by comparing the actual measured data with the simulated results, and the reason of bore polygon for the product was analyzed. The model provides the means for improving product quality and instructing technological design.
