Abstract：

As the core role of large cylindrical parts in major equipment is more and more obvious, the manufacturing technology becomes more and more important. Rolling technology is a key process of large cylindrical parts forging. In order to study the relationship between the reduction and permeability rate during cylindrical rolling, a three-dimensional finite element model of rolling cylindrical parts was built, and the numerical simulation was carried on by finite element analysis software Deform-3D. By changing the reduction of core roll，the numerical simulations with different relative feeds of 15.9%,17.2% and 19.9% for core roll were done respectively, and the distribution of deformation area during the process of cylindrical parts forging permeability was analyzed. Then the distribution of deformation area and the effect of reduction of core roll on cylinder part permeability during the process of large cylindrical parts forging permeability were obtained. By comparing with the forging penetration depth calculated by rule of thumb, the cylinder parts can be forged thoroughly when the relative feed is 19.9%, which is consistent with the conclusion gotten by rule of thumb. Therefore, it is stated that the rule of thumb can be used for judging the large cylinder forging permeability in the rolling process effectively.
