Complete equipment for preparing plate by S-shaped rolling and process method of complete equipment

Abstract

The invention relates to complete equipment for preparing a plate through S-shaped rolling and a process method of the complete equipment. The complete equipment comprises an S-shaped rolling mill, a parameter adjusting device, a roller changing device and a four-roller type transverse moving vehicle. The dislocation amount between working rollers of the S-shaped rolling mill is adjusted through circumferential rotation of the working rollers along the axes of supporting rollers, the rolling reduction of the S-shaped rolling mill is jointly adjusted through circumferential rotation of the working rollers along the axes of the supporting rollers and vertical pressing of the upper supporting roller, and the supporting rollers are connected with motors to drive the working rollers to rotate. The S-shaped rolling mill can realize S-shaped rolling and can also perform synchronous rolling by adjusting the roller speed ratio and the dislocation amount of the working rollers; the four-roller type transverse moving vehicle can achieve rapid and simultaneous replacement of the four rollers of the S-shaped rolling mill, and the roller withdrawing time is shortened; and when the S-shaped rolling mill is used for rough rolling or finish rolling, the process method combining S-shaped rolling, reverse S-shaped rolling and synchronous rolling is adopted, the rolling permeability can be improved, the plate shape problem after S-shaped rolling can be solved, and the S-shaped rolling process is applied to industrial production.

Description

technical field [0001] The invention relates to the technical field of plate rolling and forming, in particular to a complete set of equipment and a process method for preparing plates by serpentine rolling. Background technique [0002] Serpentine rolling is a new type of asymmetrical rolling technology that has been studied to improve the permeability of plate rolling in recent years. Serpentine rolling is a rolling method evolved to improve the bending problem after asynchronous rolling. Serpentine rolling is a On the basis of rolling, increase the offset between the upper and lower work rolls along the rolling direction, and suppress the post-rolling bending caused by the unequal linear speed of the upper and lower work rolls during the rolling process through the offset of the upper and lower work rolls, and adopt serpentine rolling The method can make the sheet produce shear stress in the plastic deformation zone during the rolling process, so that the shear strain is ...

AI Technical Summary

Problems solved by technology

[0003] In the actual production process of serpentine rolling, it is necessary to adjust and set the roll speed ratio and misalignment of each pass. The traditional rolling mill can no longer meet the production requirements of serpentine rolling; Although there are many studies on the theoretical analysis model of the curvature problem, there are few designs on the actual production process of the plate shape correction problem after the serpentine rolling of medium and thick plates or thin plates.
