Background
Hot galvanizing is also called hot dip galvanizing and hot dip galvanizing, is an effective metal corrosion prevention mode, and is mainly used for metal structure facilities in various industries. The rust-removed steel strip is immersed in molten zinc at about 500 ℃ to adhere a zinc layer to the surface of a steel member, so that the aim of corrosion prevention is fulfilled.
Because galvanized steel strip is galvanized through high-temperature zinc liquid, the temperature of the steel strip leaving the zinc pot is high, and after the steel strip leaves the zinc pot, part of the zinc liquid on the surface of the steel strip can react with oxygen in the air to form zinc oxide due to the gradual decrease of the external temperature, and part of the zinc liquid with high temperature can react with the steel strip to form zinc-iron alloy, which can affect the quality of the steel strip and the galvanized layer. Therefore, after the steel strip leaves the zinc liquid surface, the steel strip needs to be cooled so as to reduce side reactions after the galvanized steel strip leaves the zinc pot. However, the existing galvanized pot lacks a cooling function and cannot meet the requirement on improvement of the galvanization quality. And, during the galvanization reaction, white flue gas is generated, and if the flue gas is not treated, the environment of a workshop is polluted, and the health of workshop workers is threatened.
