Description

Technical Field

[0001] The utility model relates to the technical field of strip steel, in particular to a cold-rolled strip steel galvanizing device. Background Art

[0002] At present, cold-rolled strip steel is a widely used metal material, usually made of carbon steel or stainless steel. Its production process includes process steps such as cold rolling, pickling and quenching. Cold rolling refers to the process of reprocessing hot-rolled steel coils, rolling and pressing them multiple times at room temperature to make them thinner, wider, longer, and improve surface quality and mechanical properties. Cold rolling can achieve higher surface finish and better dimensional accuracy, while also improving the hardness, strength and toughness of steel. After cold rolling, the surface flatness and dimensional accuracy of the strip steel have been greatly improved, and it is usually used in the fields of automobiles, electrical appliances, construction, aerospace, etc. In addition, cold-rolled strip steel also has excellent properties such as corrosion resistance, wear resistance, and high temperature resistance, so it is also widely used in chemical, energy and other industries.

[0003] At present, in the process of strip galvanizing, a layer of zinc is covered on the surface of the strip to improve its corrosion resistance. This process is usually achieved by hot-dip galvanizing or electro-galvanizing. However, in actual production, due to factors such as process parameters, equipment wear or improper operation, the thickness of the electroplated layer on the surface of the strip is uneven. This will affect the quality and appearance of the product, and may even cause the functional performance of the product to decline. In addition, after galvanizing, the surface of the strip may be uneven due to factors such as temperature and tension, and may even have problems such as ripples and wrinkles. This will affect the processing quality and product performance of the strip in subsequent processes, and may even affect the service life of the product.
