Article Preview

The heavy shell ring rolling process was taken as subject investigated. Because the size of shell ring is very large and the material of shell ring is special, in order to make the shell ring to be bitten smoothly and make the rolling process stable, the double drive rolls was proposed in the shell ring rolling mill. The thermal simulation test of heavy shell ring material was made on the Gleeble 3500 thermal simulation test machine. Based on FEM, the three dimensional thermal mechanical coupled model of shell ring rolling process was built in this paper. The influences of process parameters on the stress field, strain field and mechanical parameters were investigated. Simulation results show that, with the increase of feed velocity, the strain of shell ring increases, the forging penetration condition becomes good; With the increase of friction coefficient, the equivalent plastic strain of shell ring surface layers increases, the equivalent plastic strain of shell ring middle layers has little change. The conclusions are significant for designing equipments of shell ring rolling mill and developing new rolling schedule.
