Mechanical blasting program introduction

The shot is to use high-speed rotation of the impeller to small steel shot or small iron balls thrown out high-speed hit parts of the surface, so it can be removed parts of the surface of the oxide layer. General blasting for irregular shape, several polishing head around with high efficiency and low pollution.

Repair, shipbuilding, blasting, blasting is widely used. But either shot or grit blasting, are used in the form of compressed air. Of course not shot on high speed rotation of the impeller can not be. In repair, shipbuilding industry in general, shot (shot) use in steel plate pre - treatment (before application of paint and rust); (repair, shipbuilding industry is iron ore) and more sand in forming the ship or segment, the role is the plate on the old paint and rust removing and re painting. In the repair, shipbuilding industry, the main role is to increase the blasting and blasting plate coating paint adhesion.

In fact, casting cleaning member is not only with the shot, to the large general first roller sand cleaning, is the casting of the riser after resection of put in the drum roll, composed of parts in the drum collide with each other, the sand surface most first clear off another shot or shot peening.

About 0.1 ~ 2.0 or most ~ 3.0 in shot blasting is used motor drives the impeller to rotate by the centrifugal force effect, the diameter of balls (cast pill \ cut pill \ stainless steel balls to be thrown to the workpiece surface and the workpiece surface to achieve certain manufacture in a rough degree, so that the workpiece become beautiful, or changing the workpiece welding stress compressive stress and improve workpiece service life. Almost used in mechanical field, shipbuilding and ship repairing automobile parts for aircraft components guns tank surface bridge steel structure of glass steel pipeline and so on. Blasting (pill) is to use compressed air as a driving force for the diameter in the 40-120 sand shot to the workpiece surface and the workpiece to achieve the same effect.

Different pellet size, to achieve the treatment effect is not the same. Key proposed: shot peening can also play a role in strengthening. Now domestic equipment into the a misunderstanding, think only shot in order to achieve the aim to strengthen the. \ USA Japan enterprise for enhanced is shotblasting and! Each have each advantage. Than as a tower of ivory gear such artifacts, blasting the pill angle can not be changed, can only change with frequency conversion speed. But it is processing a large amount of, speed, and shot peening is just on the contrary, blasting effect is not shot peening effect.
