Waterfall type cooling device of hot galvanized zinc steel wire

Abstract

The invention discloses a waterfall type cooling device of a hot galvanized zinc steel wire, which comprises a water receiving tank, wherein the water receiving tank has a U-shaped cross section, and one side wall structure of the water receiving tank is removed; two water spray tanks are arranged in the water receiving tank and are respectively communicated with a pipeline pump through pipelines, and valves are respectively installed on the pipelines connecting the pipeline pump and the two water spray tanks; the two water spray tanks are hollow shells, and the side walls of the two water spray tanks are both provided with water spray ports. The cooling device adopts waterfall type cooling, the jumping hot galvanized zinc can be cooled in contact with water at any position on a compression roller, labor power is saved, the production cost is reduced, and the purpose of saving resources is achieved; the weight of the galvanizing layer of the galvanized steel wire can be efficiently controlled so that the galvanizing layer becomes uniform, the requirement of environmental protection temperature is achieved, the manufacturing cost of the steel wire is lowered, the environment is protected and energy is saved; the recycling of water resources is realized, and the purpose of saving water resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a cooling device capable of controlling the coating weight of coated steel wires according to user requirements, in particular to a waterfall cooling device for hot-dip galvanized steel wires. Background technique [0002] At present, the copper tube nozzle water spray device is used to cool the hot-dip galvanized steel wire and control the weight of the galvanized steel wire. The water spray device sprays water directly on the surface of the hot-dip galvanized steel wire from one side for cooling. Under the action of water spray, the unsolidified galvanized steel wire surface moves along the direction of water spray, resulting in a thick coating on the side of the coated steel wire away from the water spray device, which exceeds the process design requirements, while the coating on the side facing the water spray device is thicker. Thin, can not meet the process d...

Problems solved by technology

Under the action of water spray, the unsolidified galvanized steel wire surface moves along the direction of water spray, resulting in a thick coating on the side of the coated steel wire away from the water spray device, which exceeds the process design requirements, while the coating on the side facing the water spray device is thicker. Thin, can not meet the process design requirements, affecting the quality of galvanized steel wire

Moreover, a copper tube nozzle on the water spray device only cools a galvanized steel wire, and the position of the moving steel wire changes at any time during the production process, so that the cooling water sprayed by the copper tube nozzle corresponding to the steel wire cannot be timely Cooling the steel wire requires a special person to manually control the direction of the nozzle, which increases production costs and wastes water resources
