Reversible rolling mill gap eliminating device

Abstract

The invention relates to a reversible rolling mill gap eliminating device. The reversible rolling mill gap eliminating device comprises an upper supporting roller, an upper working roller, an inlet balance cylinder block, an outlet balance cylinder block, a lower working roller and a lower supporting roller, wherein the upper supporting roller, the upper working roller, the inlet balance cylinderblock, the outlet balance cylinder block, the lower working roller and the lower supporting roller are all arranged in a window of a rolling mill rack, the upper working roller is arranged below the upper supporting roller, the lower working roller is arranged above the lower supporting roller, the inlet balance cylinder block and the outlet balance cylinder block are arranged on the two sides ofa bearing block of the upper working roller and a bearing block of the lower working roller correspondingly, and the eliminating device further comprises a hydraulic control system. After the scheme uses the device on the rolling mill, the requirements of the rolling mill for equipment gaps in different states can be met, a larger gap during roller replacement can be obtained to facilitate operation, the gap can be further eliminated under the action of the device in a production state to meet the functional precision of equipment, and guarantee is provided for the production stability and theproduct quality.

Description

technical field [0001] The invention relates to a device, in particular to a gap elimination device for a reversible rolling mill, and belongs to the technical field of rolling mill oil cylinder control. Background technique [0002] Hot rolling production is characterized by high temperature, high speed, high strength, and fast pace. The production environment is harsh. In addition to the reliability requirements of the equipment, the functional accuracy of the equipment must meet certain standards, otherwise it will affect the performance and quality of the product. In some equipment Position, clearance is listed as one of the functional precision that needs to be controlled. [0003] Main use background: The archway of the rolling mill is composed of two closed frames. After being installed upright, a space called a window is formed, which is used to install the roll system. The roll system of a conventional hot continuous rolling mill is generally composed of upper and l...

Problems solved by technology

This is a pair of irreconcilable contradictions; the wear of the liner is inevitable. Within a service cycle, as the wear of the liner increases, the clearance of the equipment will become larger and larger. The impact means that the functional accuracy of the equipment drop, while large equipment clearances will bring severe shock loads; these factors will exacerbate the instability of product quality
