Abstract:Dimension control is a key problem to be solved while applying ring rolling process to practical production. The dimension variation rule of ring with stepped holes during rolling process have been studied and the defect of dimension control method in available ring rolling machine has been indicated. The calculating formula has been established for on-line prediction of the precise rolling position for ring with stepped holes and the dimension control method used in radial rolling has been given out.
Key words: ring with stepped holes ring rolling on-line prediction dimension control
