Steel Bar Shot Blasting Machine Important Significance

QINGDAO KNNJOO MACHINE INC. | Updated: Aug 10, 2017

The shot blasting machine is a kind of treatment technology of the steel grit steel pill high speed drop impact on the surface of material object through the shot blasting device. Steel Bar Shot Blasting Machine Compared to other surface treatment techniques, it is faster and more efficient, and can be partially retained or stamped after the casting process.

The American company made the first shot blasting machine in the world in the 30 's. China's shot peening equipment production began in the last century 50 's, mainly imitation of the former Soviet technology.

The shot peening machine can also be used to remove burrs, scale and rust, which may affect the integrity, appearance, or definition of parts of an object. Steel Bar Shot Blasting Machine The shot peening machine can also be used to remove contaminants from the surface of a partially coated surface and provide an added surface profile for the adhesion of the coating to achieve the purpose of strengthening the workpiece.

The shot blasting machine differs from the shot peening machine in that it is used to reduce the fatigue life of the parts by adding different surface stresses, increasing the strength of the components, Steel Bar Shot Blasting Machine or preventing fretting.

Almost all steel castings, gray castings, malleable parts, ductile iron parts and so on are shot peening. This is not only to remove the surface of the casting oxide and sticky sand,Steel Bar Shot Blasting Machine but also the casting quality inspection before the indispensable preparation process, such as large-scale gas turbine chassis in non-destructive testing before the need to carry out a rigorous shot blasting blast cleaning, to ensure the reliability of testing results. In the production of general castings, blasting shot cleaning is an essential technology to find the surface defects of castings, such as skin gas hole, slag hole, Steel Bar Shot Blasting Machine sticky sand, cold insulation and peeling. Non-ferrous metal castings, such as aluminum alloy, copper alloy surface cleaning, in addition to the removal of oxidized skin, the surface defects found in castings, but also the main purpose is to remove the die casting ball burr and to obtain a decorative meaning of the surface quality,Steel Bar Shot Blasting Machine  to obtain comprehensive results. In metallurgical steel production, shot peening or pickling is a process for the mechanical or chemical removal of phosphate from a high productivity in steel production. Steel Bar Shot Blasting Machine In the production of other alloy steel plates and strips, such as silicon steel sheet, stainless steel plate, the process of cold rolling must be annealed before blasting or pickling to ensure the surface roughness and thickness accuracy of cold-rolled steel sheet.

According to the theory of modern metal strength, Steel Bar Shot Blasting Machine increasing the dislocation density of metal is the main direction to increase the metal strength. It is proved by practice that shot peening is an effective process for increasing the dislocation structure of metal. This is more important for some metals that cannot be hardened by phase transition hardening (such as martensite quenching) or by phase transformation hardening. Aviation, aerospace industry, automobiles, tractors and other components requirements of lightweight, Steel Bar Shot Blasting Machine but the reliability of more and more high, Steel Bar Shot Blasting Machine its important technological measures are the use of shot peening technology to improve the strength and fatigue strength of the components.
