Process for rapidly cleaning surface of nickel-coated billet cake

Abstract

The invention discloses a process for quickly cleaning the surface of a nickel coated steel bollet. The process is characterized by comprising the following steps: putting the nickel coated steel billet in a cleaning agent consisting of a cleaning agent A, a cleaning agent B, alcohol, a WA dehydrating agent and water, wherein the cleaning agent A consists of sodium stearate, sodium oleate, polyoxyethylene nonyl phenyl ether, sodium silicate, borax and alkylolamide, and the cleaning agent B consists of trimeric sodium phosphate, AEO9, sodium alkyl benzene sulfonate and glauber salt; and producing a clean billet cake by rinsing by deionized water, blowing by compressed air and drying by hot air. The process replaces the prior acid cleaning process, can quickly remove oil stains and nickel scraps on the surface of the billet, so the clean surface of the billet can be directly stamped so as to improve the lustrousness and appearance quality of the surface of the billet, and further reduce the labor intensity and production cost.

Description

technical field [0001] The invention relates to the technical field of coin manufacturing, in particular to a rapid cleaning process for the surface of a nickel-clad billet cake. Background technique [0002] At present, the flat cake rolling process has been added to the coin manufacturing process. During the rolling type production process, the edge of the flat cake is squeezed, and the metal nickel coating of the coin flat cake will fall off a small amount. There is a small amount of garbage, nickel shavings and oil stains on the surface of the blank cake. If the blank cake is directly imprinted, it will cause quality problems of nickel sticking in the imprint. To achieve the purpose of cleaning the surface of the flat cake. Due to the relatively old pickling process and equipment, the operator's work intensity is relatively high, and there are potential safety hazards during operation, especially manual operation. The process parameters are difficult to control, resulti...

[0002] At present, the flat cake rolling process has been added to the coin manufacturing process. During the rolling type production process, the edge of the flat cake is squeezed, and the metal nickel coating of the coin flat cake will fall off a small amount. There is a small amount of garbage, nickel shavings and oil stains on the surface of the blank cake. If the blank cake is directly imprinted, it will cause quality problems of nickel sticking in the imprint. To achieve the purpose of cleaning the surface of the flat cake

Due to the relatively old pickling process and equipment, the operator's work intensity is relatively high, and there are potential safety hazards during operation, especially manual operation. The process parameters are difficult to control, resulting in large fluctuations in product quality, and both acid and alkali are harmful to the surface of the cake. It has a corrosive effect, which reduces the service life of the blank cake. At the same time, after the blank cake is pickled, the surface gloss is reduced, which makes the surface of the blank cake after embossing dark and affects the surface quality of the blank cake.
