What is Hanger Type Shot Blasting Machine

What is hanger shot blasting machine？

Shot blasting machine is to use shot blasting machine to throw out high-speed projectile, cleaning or strengthening the casting surface casting equipment. The shot blasting machine also eliminates the sand, eliminates the core and clean up the casting.

Main range of application:

Surface cleaning

Shot blasting equipment is firstly used in the foundry industry to remove sand and oxide on the surface of cast iron and cast iron parts.

Almost all of the cast steel, gray cast iron, malleable iron, ductile iron castings have shot blasting. This is not only to remove the surface oxide skin and sand casting, the preparation process of casting quality inspection before is also indispensable, such as large gas turbine casing must be strictly shot blasting cleaning before the non-destructive testing, to ensure the reliability of testing results. In general casting production, shot peening is an indispensable process to find the surface defects such as blowhole, slag hole, sand sticking, cold separation, peeling and so on. Non-ferrous metal castings, such as surface cleaning Aluminum Alloy, copper alloy, in addition to remove oxide, found the surface defects of casting, the main purpose is to remove burr shot blasting castings and surface quality is obtained with decoration significance, comprehensive effect. In the production of metallurgical iron and steel, shot blasting or acid washing is a method of mechanical or chemical combined removal of phosphorus in order to obtain high productivity in mass production of steel. Silicon steel sheet, stainless steel sheet and other alloy steel sheet and strip production, in the cold rolling process must be carried out after annealing blasting or acid treatment, to ensure that the surface roughness of cold rolled steel plate and the thickness precision.

Workpiece strengthening

According to the modern theory of metal strength, increasing the dislocation density inside the metal is the main direction to increase the strength of metal. Practice has proved that shot blasting is an effective method to increase the dislocation structure of metal. This is of great significance for some metals that can not be further strengthened by means of phase change hardening (such as martensitic hardening, etc.) or on the basis of phase change hardening. Aviation, aerospace industry, automobile, tractor and other parts are required to be lighter, but the reliability requirements are higher and higher. The important technological measure is to use shot peening to improve the strength and fatigue strength of components.
