Galvanizing sink roll

Abstract

The invention discloses a galvanized sinking roller, which is installed and arranged in a zinc pot and lower than the zinc liquid surface, and is used for coating a metal strip; the feature is that the extending direction of the metal strip above the sinking roller is also provided with roller shafts parallel to each other The stabilizing roll and the positioning roll; the metal strip extends from the zinc pot below the zinc liquid level and is at the lowest point at the sinking roll. After the metal strip contacts the sinking roll, it goes around the sinking roll and turns upward to extend and is placed on the stabilizing roll. Between the stabilizing roller and the positioning roller, there is no contact between the stabilizing roller and the positioning roller up and down, so that the metal belt can smoothly move between the stabilizing roller and the positioning roller without swinging; the surface of the sinking roller is covered with The circumferential single helix or double helix slag discharge groove. The invention has reasonable structure and stable operation, so that the surface of the obtained galvanized layer is uniform without marks and the quality is stable.

Description

technical field [0001] The invention relates to a cold-rolling galvanizing unit, in particular to a zinc pot roll, which is a key equipment of the cold-rolling galvanizing unit, installed in the zinc pot. Background technique [0002] The zinc pot roll is the key equipment of the cold rolling galvanizing line, installed in the zinc pot. The stability of the zinc pot roll system directly affects the quality of the zinc layer on the surface of the metal strip. Due to the stability of the roll system, most iron and steel enterprises currently produce metal strips with more or less roll marks on the surface that cannot be eliminated. affect the quality of the finished product. [0003] In addition, at present, most of the roller bearing bushes produced by manufacturers have integral spray welding structure and ceramic sleeve structure, but in the later stage of the production cycle, the vibration of the roller system is prone to intensification, because the thickness of the spr...

Problems solved by technology

The stability of the zinc pot roll system directly affects the quality of the zinc layer on the surface of the metal strip. Due to the stability of the roll system, most iron and steel enterprises currently produce metal strips with more or less roll marks on the surface that cannot be eliminated. affect the quality of the finished product

[0003] In addition, at present, most of the roller bearing bushes produced by manufacturers have integral spray welding structure and ceramic sleeve structure, but in the later stage of the production cycle, the vibration of the roller system is prone to intensification, because the thickness of the spray welding layer is completely worn away, which intensifies the wear body. The tile sleeve cannot get the running balance point, and the ceramic sleeve may be cracked due to the shape and tension of the metal strip, resulting in serious equipment production accidents
