Surface cleaning, stainless steel casting products are indispensable processes, the most important role is in addition to stainless steel casting processing metal casting surface sand and iron oxide and a series of impurities, so that the surface of stainless steel castings become stainless steel metallic luster, to achieve product standards.

What is the common method for cleaning stainless steel casting?

1. The dry cleaning method is to spray the main friction surface of the stainless steel casting surface cleaning. The shot peening is simply driven by compressed air, so that the projectile is sprayed to the surface stainless steel casting at a certain speed to remove the stainless steel casting process. The surface of iron and iron oxide, but this friction cleaning method has been used by the factory due to inefficiency, uneven cleaning, poor results, etc., and has almost been eliminated.

2, wet cleaning method, stainless steel casting processing principle is mainly the principle of electro-hydraulic hammer effect, high-voltage pulse generator is placed in water through a special electrode for phase discharge, resulting in large hydraulic shock. Due to the surface adhesion of the stainless steel casting process and the elastic modulus and vibration frequency of the casting itself, the purpose of sand cleaning is achieved. For the shape of stainless steel castings with complex stainless steel castings, stainless steel casting processes such as deep holes, blind holes, and cavities have a more effective cleaning effect. It is currently the most widely used series of stainless steel casting casting surface cleaning methods.

As we all know, the production of stainless steel casting processing should not be magnetic, but some products are made of magnetic. Some stainless steel casting manufacturers believe that the material is the cause, but after the spectral test, the material is not abnormal, many people can not find stainless steel casting Processing solves this problem. After discussing the new discovery, stainless steel casting processing can access a large amount of information and related technicians. Stainless steel castings and magnetic cooling are formed because of the stainless steel casting process during the cooling process. The internal structure changes, part of the austenite becomes martensite, and the body structure of the stainless steel casting process is magnetic.
