Problems solved by technology

However, in the current technology, the treatment agents used in the treatment process are mostly strong acids, strong alkalis, and difficult-to-degrade substances. The treated wastewater pollutes the water body and needs to be further treated and discharged, which increases the cost, and the treated stainless steel The size of the workpiece is relatively large

Abstract

The invention discloses a surface treatment process of a high-quality-surface stainless steel workpiece. The surface treatment process of the high-quality-surface stainless steel workpiece comprises the following steps: mechanically polishing the surface of a stainless steel workpiece at first, and then carrying out oil removal treatment on the surface; washing the stainless steel surface with water after oil of the surface is removed, and then carrying out pickling; washing the surface of the stainless steel workpiece with water after pickling; adding the washed stainless steel workpiece in an oscillating mill, and adding a grinding material and grinding fluid; cleaning the surface of the ground stainless steel workpiece by using a grinding fluid cleaning agent; and feeding the treated stainless steel workpiece in a temper mill, and carrying out surface roughness homogenized finishing treatment to obtain the high-quality-surface stainless steel workpiece. The surface of the stainless steel workpiece treated by the method is glossy, roughness is greatly reduced, rust resistance is good, and a treating agent used in a treating process is environmentally friendly and non-toxic, and is harmless to the environment.

Description

[0001] Technical field: [0002] The invention relates to the technical field of surface treatment, in particular to a surface treatment process for a high-quality surface stainless steel workpiece. [0003] Background technique: [0004] Ordinary stainless steel materials have good corrosion resistance "stainless" performance in water, steam, and air, but they are prone to pitting, pitting, and crevice corrosion in many corrosive media. Therefore, ordinary stainless steel cannot adapt to more and more Such as chemical, food, biopharmaceutical and other fields to its performance requirements. In order to improve the corrosion resistance of stainless steel materials, it is necessary to form a dense oxidation protective layer on the surface of stainless steel workpieces, so as to achieve the effect of protection. However, in order to obtain a good protection effect, it is often necessary to carry out surface treatment before its treatment, so as to remove the oxide layer, oil, e...
