Problems solved by technology

This process has the advantages of simplicity and convenience, no damage to the base material, and no influence on the strength, but it cannot meet the requirements for occasions with high requirements for surface appearance and corrosion resistance.
The second method is to use electrolytic polishing, which can improve some surface quality and corrosion resistance, but the processing is troublesome, the cost is high, and it cannot meet the high quality requirements. This method cannot be used for large workpieces.

Embodiment Construction

[0008] In the following, the present invention will be further described in conjunction with the embodiments.

[0009] The vessel is made of austenitic stainless steel hot-rolled medium plate with a thickness of 4mm-16mm. The diameter of the vessel is 600mm-2600mm, and the length of the vessel is 1000mm-6000mm. After the vessel is welded, the overall mechanical polishing is performed. Because the vessel is large, polishing Generally, automatic polishing with abrasive belts should be used. If the conditions are not available, manual polishing can also be used. However, the quality is poor and the efficiency is low. The overall polishing is completed. According to the position to be decorated, the decorative parts are mirror-polished For treatment, 120 mesh, 360 mesh, 800 mesh, 1500 mesh abrasive belt and polishing wheel are used for treatment respectively. In the final polishing, a suitable polishing paste must be selected until the mirror surface is thrown. Under different circums...

Abstract

The invention discloses a disposing technology of stainless steel container surface, which comprises the following steps: adopting mechanic polishing to predispose, polishing local mirror, disposing decorative prevention, disposing shot-blast with diameter at 0.2-1.2mm, cleaning surface, coating surface, adsorbing dust, blowing dust, brushing, spraying film liquid, coating film liquid through high-pressure static specific equipment.

Description

Technical field [0001] A process for treating the surface of a stainless steel container belongs to the field of stainless steel container manufacturing. Background technique [0002] Stainless steel containers are often used in water supply equipment, pharmaceutical machinery, food machinery, and chemical machinery. Such containers must undergo a welding process during the manufacturing process. The welds are prone to discoloration and oxidation, and are mainly treated by pickling and passivation. At present, there are two main processes for the outer surface treatment of this type of container. The first is to directly carry out the pickling passivation treatment on the surface of the original base metal and the weld, then rinse with water, and dry the package to become the finished product. This process has the advantages of being simple and convenient, not damaging the base material, and not affecting the strength, but it cannot meet the requirements for occasions that requir...
