Description

Technical Field

[0001] The present application relates to the field of hot-dip galvanizing equipment, and in particular to a three-roller six-arm scraper for a zinc pot. Background Art

[0002] When producing galvanized steel sheets, the steel strip is transmitted between an immersion roller and two stabilizing rollers and adhered to the roller surface. The "three rollers" are immersed in the zinc pot. The control of the coating thickness is related to the steel strip speed, the zinc pot temperature, the temperature of the steel strip entering the zinc pot, the annealing time, and the zinc dipping time. Although the roller surfaces of the immersion roller and the stabilizing roller are grooved, an alloy layer is still inevitably produced during the galvanizing process. The alloy layer adheres to the roller surface, which not only affects the production quality of the galvanized steel sheet, but also shortens the service life of the roller.
