Roller surface treatment device for steel rolling mill

Abstract

The invention discloses a roller surface treatment device for a steel rolling mill. The roller surface treatment device comprises a bottom plate; a rectangular groove is formed in the middle of the outer wall of the top of the bottom plate; the inner walls of the two sides of the rectangular groove are quarter arcs; first springs are arranged on the two sides of the outer wall of the top of the bottom plate correspondingly; a placement plate is disposed on the outer walls of the tops of the two first springs; a fixing strip is disposed on the outer wall of one side of the placement plate; a strip-shaped groove is formed in one side of the outer wall of the top of the bottom plate; a sliding block is slideably connected with the inner wall of the bottom of the strip-shaped groove; a positioning hole is formed in the outer wall of one side of the sliding block; and supporting plates are disposed in the middle of the outer wall of the top of the sliding block and on one side of the outerwall of the top of the bottom plate correspondingly. By means of the roller surface treatment device for the steel rolling mill, supporting blocks can be prevented from colliding with the rectangulargroove and being damaged, the situation that the device cannot work due to insufficient motive power can be prevented, the environment-friendliness of the device can be improved, and the situation that a roller falls off from a fixing sleeve and is damaged due to insecure fixing can be prevented.

Description

technical field [0001] The invention relates to the technical field of rolling mills, in particular to a roll surface treatment device for a rolling mill. Background technique [0002] At present, the roll is an important part of the rolling mill in the rolling mill. The pressure generated by a pair or a group of rolls is used to roll the steel. Since the strip is galvanized at the front of the unit, galvanization is often attached to the surface of the strip. Dust, these dusts will adhere to the rolls of the rolling mill when the strip steel passes through the rolling mill. With the subsequent rolling, the galvanized dust that has been attached to the rolls will be reprinted on the subsequent strip steel, and produce clearer The indentation will affect the surface quality of the strip. [0003] After searching, the Chinese patent authorization number is the patent of CN204365638U, which discloses a roll surface cleaning device of a tempering machine in a cold-rolled hot-di...

AI Technical Summary

Problems solved by technology

There are the following deficiencies in the above-mentioned patents: 1. When cleaning the roll, although the surface of the roll can be cleaned by washing with water, water stains will corrode the surface of the roll and easily make the surface of the roll rust. After the water stain dries up, it will leave stains on the surface of the roll, resulting in unclean cleaning of the roll; 2. When the roll is washed with water, a large amount of water resources will be wasted, which is not conducive to the environmental protection of the device; 3. On the surface of the roll When cleaning, it is necessary to fix the roll. Since the surface of the roll is relatively smooth, it is easy to cause the roll to fall off from the device and damage the roll.
