Description

Technical Field

[0001] The utility model relates to the technical field of steel strip production, in particular to a water mist cooling device for a galvanized steel strip. Background Art

[0002] Steel belt can be used as the traction and carrying component of belt conveyor, and can also be used to bundle goods. It is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Since the steel belt needs to be exposed to the air for a long time, it is easy to rust on the surface of the steel belt. In order to effectively protect the steel belt from corrosion. The existing method is to plate a zinc layer on the outer surface of the steel belt. The existing coating method is to place the steel belt in a high temperature environment, and then plate the zinc material on the surface of the steel belt by hot dip.

[0003] Publication No. CN216864289U discloses a water mist cooling device for galvanized steel strip, which can meet the processing requirements of steel strip by cooling the steel strip, thereby effectively improving the production efficiency of the steel strip. However, during the use of the device, the impurities and dust on the surface of the galvanized steel strip will separate from the steel strip during the cooling process, flow into the water collection tank along the water flow, and then be pumped out into the circulation system by the water pump mechanism. However, the spray port of the atomizing nozzle has a small diameter and is easily blocked, resulting in the impact of steel strip flushing. For this reason, we propose a water mist cooling device for galvanized steel strip. Utility Model Content
