Cleaning method of foreign matter on the tension roller of the rewinding unit

Abstract

The invention discloses a method for cleaning foreign matter on a tension roller of a recoiling unit, and relates to the field of coiled steel production. It includes firstly determining the specific position of the strip steel by checking the shape, size, and size of the foreign matter, and then performing a preliminary screening of the unevenness of the foreign matter according to the strip threading direction of the tension roll of the recoiling unit, and judging the front and rear of the tension leveler. The tension roller in the corresponding area is cleaned by reversing and positioning by opening a hole at the position of the foreign object. The present invention directly removes the foreign matter by punching holes online and reversing to a fixed position, which greatly reduces the processing time, improves the accuracy of the cleaning position, and realizes fixed-point cleaning; the cleaning method is popularized in other recoiler lines, The safety risk is greatly reduced, which will effectively improve the safety factor, and the overall effect is remarkable.

Description

technical field [0001] The invention relates to the field of coiled steel production, in particular to a method for cleaning foreign matter on a tension roller of a recoil unit. Background technique [0002] The tension rollers of the recoiling unit in the finishing workshop of the cold rolling mill are all polyurethane rubber rollers. When foreign matter such as rotten edges, warped skin, or recoiling welding slag is brought into the tension roller and embedded in the roller surface through the strip steel, the foreign matter is embedded in the roller. , causing quality problems on the surface of the board, it needs to be shut down for processing, which affects the quality and production efficiency, so it needs to be cleaned up in time. However, since multiple rollers of the tension roller of the recoiling unit are covered by steel strips, and the width of the production specification of the unit continues to increase, there is insufficient space for personnel to clean up, ...

Problems solved by technology

[0002] The tension rollers of the recoiling unit in the finishing workshop of the cold rolling mill are all polyurethane rubber rollers. When foreign matter such as rotten edges, warped skin, or recoiling welding slag of the incoming material is brought into the tension roller through the strip steel and embedded in the roller surface, the foreign matter is embedded in the roller. , resulting in board surface quality problems, need to stop processing, affecting quality and production efficiency, so it needs to be cleaned up in time

However, since multiple rollers of the tension roller of the recoiling unit are covered by steel strips, and the width of the production specification of the unit continues to increase, there is insufficient space for personnel to clean up, and it is difficult to clean foreign matter on the surface of the tension roller; in addition, when cleaning the wrapped tension roller During the cleaning process, the strip steel needs to be loosened first, and personnel reach into the gap to deal with foreign objects on the tension roller, which poses a relatively large safety risk
