Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip tinning of alloy steel strips, in particular to a device for hot-dip tinning of the surface of an alloy steel strip. Background Art

[0002] Alloy steel strip is a special steel product composed of iron, carbon and other alloy elements. During the production and processing of steel strip, it is necessary to use hot-dip tinning process to cover the molten tin on the surface of the steel strip in order to improve the corrosion resistance, aesthetics and other properties of the steel strip.

[0003] The existing hot-dip tinning device for alloy steel strip surface is mainly composed of a conveying mechanism, a tin liquid pool and a cooling system. During the tinning process, the steel strip is first sent into the tin liquid pool through the conveying mechanism. In the tin liquid pool, the steel strip contacts with the molten tin liquid. After immersion, the steel strip leaves the tin melting furnace and enters the cooling system. During the cooling process, the tinned layer gradually solidifies and fixes on the surface of the steel strip. Finally, the cooled steel strip is rolled up by the winding device to complete the entire hot-dip tinning process.

[0004] The existing hot-dip tinning device for the surface of alloy steel strips does not perform cleaning pretreatment before the steel strips enter the tin liquid pool, so that oil, dust and other particulate matter may adhere to the surface of the steel strips, thereby affecting the uniformity and adhesion of the molten tin and reducing the quality of product processing; therefore, a hot-dip tinning device for the surface of alloy steel strips is proposed to address the above problems.

Before the steel strip enters the tin liquid pool, it is necessary to remove the impurities remaining on the surface of the steel strip. Through the operation of the water pump, the water in the water tank flows into the U-shaped tube through the conveying pipe, and finally sprayed out through the atomizing nozzle 4, so that the water is evenly covered on the entire surface of the steel strip, so that it can effectively dissolve or soften the oil, rust and other impurities on its surface. Subsequently, through the action of the scraper, the surface of the steel strip can be scraped and cleaned, so that these impurities can be quickly and thoroughly removed, and efficient cleaning is achieved to ensure that the surface of the steel strip is clean and free of impurities, thereby improving the adhesion and uniformity of the tin plating layer, thereby improving the processing quality of the product.
