Steel Bar Shot Blasting Machine The Role Of

QINGDAO KNNJOO MACHINE INC. | Updated: Jul 12, 2017

The type of shot blasting machine is mainly used for steel plate and all kinds of small steel surface cleaning, through the shot blasting, Steel Bar Shot Blasting Machine remove the steel surface corrosion, dirt, oxide, etc., Steel Bar Shot Blasting Machine so that steel rust, decontamination, Improve the anti-fatigue strength of the workpiece, and ultimately achieve the purpose of improving the steel surface and intrinsic quality. Steel Bar Shot Blasting Machine This equipment can be used with preheating, painting, drying, etc. before and after the process equipment to form a production line, can also be used as a separate shot blasting.

Through the type of shot blasting machine mainly include: workpiece conveyor roller, Steel Bar Shot Blasting Machine the main vice shot blasting room, screw conveyor, bucket elevator, pill separator, shot blasting machine, pill control valve, powder pipeline, platform and railings , Dust removal system, Steel Bar Shot Blasting Machine electronic control system.

Shot blasting machine is through the shot blasting machine will be high-speed cast steel shot off the impact of material in the surface of a material processing technology. Steel Bar Shot Blasting Machine Compared to other surface treatment techniques, it is faster, more efficient, Steel Bar Shot Blasting Machine and can be partially retained or stamping after the casting process.

In the 1930s, American companies made the first shot blasting machine in the world. China's shot peening equipment production began in the last century 50's, Steel Bar Shot Blasting Machine mainly imitation of the former Soviet Union technology.

Shot blasting machines can also be used to remove burrs, scale and rust, which may affect the integrity, appearance, or definition of the object part. The shot blasting machine can also remove contaminants from the surface of a partially coated surface and provide an enhanced surface profile for the coating to achieve the purpose of strengthening the workpiece.

Shot blasting machine is different from the shot blasting machine, which is used to reduce the fatigue life of the parts by increasing the surface stress, Steel Bar Shot Blasting Machine increasing the strength of the parts, or preventing jogging.

Shot blasting equipment is first used in the casting industry cast steel, Steel Bar Shot Blasting Machine cast iron pieces of the surface of sand and the removal of oxide.

Almost all of the cast steel, gray castings, Magang, ductile iron and so on to be shot blasting. This is not only to remove the surface of the castings oxide and sticky sand, but also the casting quality inspection before the indispensable preparation process, such as large gas turbine chassis in the nondestructive testing must be carried out before the strict shot peening to ensure the results of the test reliability. Steel Bar Shot Blasting Machine In the general casting production, throwing shot peening is found in the casting surface defects such as subcutaneous stomata, slag and sticky sand, cold separation, from the skin and other essential means of technology. Non-ferrous metal castings, such as aluminum alloy, copper alloy surface cleaning, in addition to scavenging oxide, found the casting surface defects, the more important purpose is to throw shot peening to remove the burrs of die cast and get a decorative surface quality , To obtain a comprehensive effect. Metallurgical Iron and steel production, Steel Bar Shot Blasting Machine throwing peening or pickling is to ensure that large quantities of steel production to obtain high productivity and the use of mechanical or chemical joint removal of phosphorus skin of a process. Silicon steel sheet, Steel Bar Shot Blasting Machine stainless steel sheet and other alloy steel plate, with the production process, in the cold rolling process must be carried out after the annealing and shot blasting or pickling treatment to ensure that the cold-rolled steel plate surface roughness and thickness accuracy.

According to the theory of modern metal strength, Steel Bar Shot Blasting Machine increasing the dislocation density inside the metal is the main direction to improve the strength of the metal. Practice has proved that shot blasting is to increase the metal dislocation structure of the effective process. This is of great significance to the fact that some metals can not be hardened by phase change hardening (eg, martensitic quenching, etc.) or to achieve further hardening of the workpiece. Aviation, aerospace industry, automobiles, tractors and other parts of the requirements of light, Steel Bar Shot Blasting Machine but the reliability requirements are getting higher and higher, the important process is to use throwing shot peening process to improve the strength and fatigue strength.
