Description

Technical Field

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

[0002] Strip steel is a narrow and long steel plate. It is widely used in the fields of automobile industry, machinery manufacturing industry, construction engineering, steel structure and daily hardware. Strip steel can be made into cold-bent steel and welded steel pipes. The iron element in the strip steel is easy to react with oxygen in humid air and penetrate into the inside. The chemical properties of zinc are much more active than iron. Therefore, by coating the surface of the strip steel with zinc coating, zinc takes away oxygen atoms during the oxidation process, making it difficult for iron to oxidize. At the same time, a dense oxide film is formed on the surface of zinc, which prevents further oxidation. When the strip steel is hot-dip galvanized, the temperature of the zinc liquid is generally around 460 degrees. The temperature of the strip steel after galvanizing is also around 460 degrees when it leaves the surface of the zinc liquid. The liquid on the surface of the strip steel needs to be cooled by a cooling device before it can solidify.

[0003] The existing patent number CN218621000U discloses a post-galvanized cooling device for galvanized steel strip, including a water tank, a box cover fixed on the water tank, a cooling box fixed on the box cover, the cooling box and the box cover are connected through a fixed embedded drainage pipe, a water pump is fixed on the box cover, a water pump pipe connected to the water inlet of the water pump is fixedly embedded on the box cover, a water inlet pipe connected to the water outlet of the water pump is fixedly embedded on the cooling box, plate frames are fixedly embedded on both sides of the cooling box, conveying rollers are rotatably installed on the upper and lower ends of the inner wall of the plate frame, the galvanized strip body passes through the conveying rollers, a cover plate is fixed on the cooling box, and an extrusion roller that is in close contact with the galvanized strip body is rotatably installed on the cover plate.

The galvanized steel strip cooling device is provided with a feed inlet, an air inlet, a refrigeration rack, a baffle, a refrigeration plate, a fan, a water tank, a water extraction pipe, a water pump, a water delivery pipe, a guide pipe and an atomizing nozzle. When the steel strip enters the shell from the feed inlet, the water pump is first started to make the water extraction pipe extract the cooling water in the water tank, and the cooling water is delivered to the guide pipe through the water delivery pipe, and then the guide pipe delivers the cooling water to each group of atomizing nozzles for spraying, so as to cool the steel strip. Then, the fan is started to blow the external air source into the refrigeration rack, and then the refrigeration plate is started to cool the air in the refrigeration rack. The cooling effect of the device is further enhanced by preventing the air inside the refrigeration rack from flowing too fast, thereby improving the cooling efficiency of the air and further strengthening the cooling effect of the device. Finally, when the strip enters the water tank, the strip is quickly cooled by immersion in water. This step-by-step cooling method greatly improves the cooling efficiency of the strip.

Finally, the two groups of sponge blocks are used to adsorb water stains adhered to the surface of the strip, thereby cleaning the water stains. This design enables the device to have the function of cleaning water stains, avoids the problem of a large amount of cooling water remaining on the surface of the galvanized strip, improves the quality of the product, and meets the use requirements.
