Surface cleaning application of shot blasting machine for steel plate pretreatment line

1. Cleaning the surface of castings and sticky sand is also an indispensable preparatory process before the quality inspection of castings.

2. In the production of silicon steel sheet, stainless steel sheet and other alloy steel sheets and strips, the cold-rolling process must be annealed and then shot blasted or pickled to determine the surface roughness and thickness accuracy of the cold-rolled steel sheet.

3. In the production of general castings, shot blasting is an indispensable process for discovering surface defects of castings such as subcutaneous pores, slag holes, sand sticking, cold insulation, and peeling.

4. In metallurgical iron and steel production, shot blasting or pickling is a process method to remove the phosphorus skin by mechanical or chemical combination to determine the high productivity in the mass production of iron and steel.

5. Surface cleaning of non-ferrous metal castings, such as aluminum alloys, copper alloys, etc., in addition to cleaning oxide scales and discovering surface defects of castings, the main purpose is to clean the burrs of die castings and obtain decorative meanings by shot blasting The surface quality has a comprehensive effect.

6. For example, the casing of a large gas turbine must be subjected to strict shot blasting before non-destructive testing.
