Process method and water milling equipment used for treating metal plate surface

Abstract

The invention provides a process method and water milling equipment used for treating a metal plate surface. The process method includes partial restoration, sand blasting or shot blasting treatment and water milling treatment. Defects on the surface of a material are detected by naked eyes, a grinding wheel and / or a thousand impeller and / or a welding machine are / is utilized to smooth the defects to make the surface of the material flat, secondly, sand blasting or shot blasting treatment is carried out, one of a sand blasting machine or a shot blasting machine is used for conducting oxide skin breaking on the surface of the material, surface consistency is formed, the surface of a plate after sand blasting or shot blasting treatment is dark and is possibly defective, in order to allow people to see the defects on the surface of the material, a worker uses the water milling equipment to remove oxide skin, the surface of the material is brightly colored, in this way, the problem that the defects on the surface of the material are covered up due to the color of the surface of the plate is avoided, at the same time, the use of acid is avoided to remove the oxide skin on the surface of the plate, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a process method and water milling equipment for treating the surface of metal plates. Background technique [0002] At present, the surface treatment of materials is a combination of shot blasting and pickling or sand blasting. The combination of shot blasting and pickling is that people first crush the oxide skin on the surface of the material through a shot blasting machine to provide convenience for the next step, and then use it. The acid reacts chemically with the oxide layer on the surface of the material, and then removes the oxide layer on the surface of the material to obtain a bright metal surface. At the same time, in the process of pickling, it cannot guarantee that all the acidic materials will chemically react with the oxide layer on the surface of the material. When people discharge liquid, it will inevitably lead to the problem of acid pollutio...
