Surface cleaning


Shotblast equipment first used in the foundry cast steel, cast iron surface sticky sand and oxide skin removal.


Almost all steel castings, gray castings, Malleable steel, ductile iron pieces, etc. must be shot blasting. This is not only for the removal of oxide scale and sticky sand casting surface, but also casting quality inspection indispensable preparatory steps, such as large gas turbine casing in the non-destructive testing before the strict shot blasting to ensure that the test results reliability. In the production of general castings, shot peening is an indispensable technological measure for finding casting surface defects such as subcutaneous pores, slag holes and sticky sand, cold separation, peeling and the like. Non-ferrous metal castings, such as aluminum, copper alloy surface cleaning, in addition to removing the oxide scale, found that the surface defects of castings, the more important purpose is to use shot peening to clear the burrs and the decorative surface of the decorative surface quality , Get comprehensive effect. In metallurgical steel production, shot peening or pickling is a process that combines the mechanical or chemical removal of phosphorus skins to ensure high productivity in mass production of steel. In the production of other alloy steel plates and strips such as silicon steel sheets and stainless steel sheets, blasting or pickling must be performed after the cold-rolling process to ensure the surface roughness and the thickness accuracy of the cold-rolled steel sheet.

Workpiece reinforcement


According to modern metal strength theory, increasing the dislocation density inside the metal is the main direction to improve the metal strength. Shot blasting is proven to increase the metal dislocation structure of the effective method. This is some of the metal can not be through the transformation hardening (such as martensite hardening) or to achieve the transformation hardening based on the further strengthening of the workpiece, the more important. Aerospace, aerospace industry, automobiles, tractors and other parts require light weight, but the reliability requirements are getting higher and higher, shot blasting machine is the important process measures using shot peening process to improve the strength and fatigue strength of components.
