The Effect of the Initial Temperature of Ring Blank on Conical Ring Rolling Process

Article Preview

Abstract:

A FE model of radial conical ring rolling process with a closed die structure on the top and bottom part of driven roll (RCRRCDS) process was set up based on ABAQUS/Explicit software. The effect of the initial temperature of conical ring blank on equivalent plastic strain (PEEQ) and temperature distribution of rolled ring, average rolling force and average rolling moment was investigated. The results indicated that with the increase of the initial temperature of ring blank, the PEEQ distribution of rolled ring becomes uniform at first and then less uniform; the temperature distribution gradually becomes homogeneous; and both average rolling force and average rolling moment decrease. When the initial temperature of ring blank is 925°C, the PEEQ distribution of rolled ring is most uniform; the temperature distribution of rolled ring is relatively uniform; the average rolling force and average rolling moment are relatively smaller.
