Main function of Metal surface treating machine (shot blaster or shot blasting machine) in Foundry Industry

The shot blasting equipment is first applied to the surface sanding and scale removal of cast steel and cast iron parts in the foundry industry.

Almost all steel castings, ash castings, Malleable Fitting, ductile iron parts, etc. are subject to shot blasting. This is not only to remove the oxide scale and sand on the surface of the casting, but also an indispensable preparation process before the quality inspection of the casting. For example, the large gas turbine machine shell must be subjected to strict shot blasting before non-destructive testing to ensure the flaw detection results reliability.

In the production of general castings, shot blasting is an indispensable process for discovering surface defects such as subcutaneous pores, slag holes, and sand, cold insulation, and peeling. Surface cleaning of non-ferrous metal castings, such as aluminum alloys, copper alloys, etc., in addition to removing oxide scales and surface defects of castings, the main purpose is to remove the burrs of the die-casting parts and obtain the decorative surface quality, to obtain a comprehensive effect.

In the production of metallurgical steel, shot blasting or pickling is a process for mechanically or chemically removing phosphorus skin to ensure high productivity in mass production of steel. In the production of other alloy steel sheets and strips such as silicon steel sheets and stainless steel sheets, annealing or pickling treatment must be performed during the cold rolling process to ensure the surface roughness and thickness accuracy of the cold rolled steel sheets.rim surface cleaning equipment - 副本
