Influence of Roll Elastic Deformation to Gap Setting for Plate Mill

Base on the mechanical model of plate rolling process, the gap variation was transferred to roll elastic deformation. By the influence function method the influence of plate width, work roll radius, backup roll radius, work roll crown, backup roll radius and rolling force on gap setting were calculated. Results show that: 1. roll deformation decreases linearly with the increase backup roll radius; 2. roll deformation is increasing linearly with the increases of work roll radius; 3. roll deformation increases linearly with the increase of backup roll crown; 4. roll deformation is linear to work roll crown, but the plate width can change the direction of linear relation; 5. roll deformation increase linearly with the increase of rolling force. If the rolling force is constant, the roll deformation is invariant.
