Segmented Roller Tensile Stress Distribution Control Device

Abstract

The invention discloses a segmentation compression roller type tensile stress distribution control device which comprises a tension supporting roller mechanism and a short compression roller mechanism. The tension supporting roller mechanism comprises a supporting roller rack, a tension supporting roller and upward pressing cylinders. The tension supporting roller can be driven by the upward pressing cylinders at the two ends of the tension supporting roller to make up-down asynchronous movement along a U-shaped groove in the supporting roller rack. The short compression roller mechanism comprises a steel structure, a transverse movement assembly and a plurality of short compression roller assemblies. The transverse movement assembly comprises a transverse movement cylinder and a transverse movement beam, and the transverse movement beam can be driven by the transverse movement cylinder to make transverse movement along the steel structure. Each short compression roller assembly comprises a short compression roller, a short compression roller support and downward pressing cylinders, wherein the short compression roller can be driven by the downward pressing cylinders at the two ends of the short compression roller to rotate around the transverse movement beam, so that the downward pressing amount of the short compression roller is controlled. The segmentation compression roller type tensile stress distribution control device can be used for presetting strip steel tensile stress transverse distribution at an inlet of a rolling mill, and also can be used as an effect means for plate shape adjustment in the rolling process.

Description

technical field [0001] The invention belongs to the technical field of steel rolling equipment, and in particular relates to a segmented pressure roller type tension stress distribution control device, which can change the transverse distribution of strip steel tension stress and is suitable for strip steel reversible rolling and continuous rolling production lines. Background technique [0002] In the process of cold-rolled strip shape setting and shape control, rolling tension plays a vital role in strip shape. By reasonably increasing the rolling tension, the lateral flow of the metal can be increased, the thickness of the exit can be reduced, the section of the rolled piece is more uniform, and a good surface quality of the strip can be obtained. At the same time, increasing the rolling tension can reduce the rolling pressure and rolling load during the rolling process, reduce the deformation resistance of the strip, reduce the wear of the roll, prevent the strip from ru...
