Abstract:
The speed-up of the rolling production makes the effect of rate-sensitive material on the rolling process significant. In this paper the Rigid-viscoplastic F.E.M, has been used successfully to simulate the steady process of plate-rolling of rate-sensitive material. The experimental results of testing the rolling force is in good agreement with the result of computations. The emphasises put on the discussion of the effect of the rolling velocity on the rolling process.Some new results,which are difficult to obtained by other methods, are obtained. The analysis above express that the forward slip increases with increasing of rolling velocity.
