In spite of assumptions of plane-strain, the friction at the roll-workpiece is presumed as viscosity, this paper calculated the unit pressure and rolling-force of flat-rolling process by rigid-plastic BEM, and compared results with the results of experiment and FEM.

Finite element analysis on front end bending during heavy plate rolling;

In the process of heavy plate rolling,mastering the rule of material's width elongation and improving the forecasting precision of width elongation are the key point to ensure that the final plate width can meet customers' requirements.

Analysis of strip rolling using three-dimensional coupled finite element method;

A computer model for simulation of the three-dimensional strip rolling process has been developed by using an interactive procedure to analyze the coupled deformation between strip and rolls.

A 3-dimensional strip rolling analysis model considering strip lateral flow is developed in order order to overcome the disadvantages in the traditional theories.

Heat treatment of Mg-Zn-Y-Zr alloy rolling sheet

The results show that the grains in the single direction rolling sheet is changed from strip to equal axis shape because of the recrystallization and twin crystals disappearance during annealing heat treatment,and there are some fine grains although part grains are grown.
