Direct type horizontal moving device of working roll

Abstract

The invention is suitable for the technical field of metallurgical equipment, and provides a direct type horizontal moving device of a working roll. The direct type horizontal moving device comprises a rack, a hydraulic cylinder, a fixed block and a roll bending block, wherein the fixed block is fixedly arranged on the rack, the hydraulic cylinder is arranged at the inner part of the fixed block, a movable end of the hydraulic cylinder is positioned in the roll bending block, and the hydraulic cylinder drivers the roll bending block to move in the fixed block in a reciprocating way under the guiding action of the fixed block. According to the direct type horizontal moving device provided by the invention, the roll bending block is directly driven through the hydraulic cylinder, the structure is compact, a tapered wedge, a tapered wedge cylinder and an auxiliary cylinder are omitted, the horizontal moving of the working roll and the roll exchanging operation can be simple and reliable, the use of various types of working roll bearing seats can be met, and the application is wide.

Description

technical field

[0001] The invention belongs to the technical field of metallurgical equipment, in particular to a direct type work roll horizontal moving device. Background technique

[0002] In order to roll high-strength steel strips such as silicon steel, stainless steel and special steel, it is necessary to use a rolling mill with a smaller diameter of the work roll, and as the diameter of the work roll decreases, the horizontal deflection of the work roll increases significantly, and the horizontal stiffness decreases significantly. Shape control is very unfavorable. The horizontal deflection of the work roll can be reduced by using the work roll horizontal movement technology. In the prior art, the specific plan for the horizontal movement of the work rolls is as follows: setting wedges on the roll bending blocks on both sides to push the roll bending blocks, and then push the work roll chocks, so that the work rolls move along the rolling direction. Because the wed...
