Blast-enhanced treatment of hardy shrapne
Now the variety of hard metal shrapngar professional raw materials day also increased, its follow-up processing methods are also changing and improving, such as structural shape, heat treatment and appearance quality processing, so that the use of metal shrapngar more satisfied with the function of special commodity requests, at the same time, further enhance the use of metal shrapngar commodity characteristics. The blasting of hardy shrapne is one of them.
1) Combined pill treatment. A combination of pellets, also known as multiple sprays. Many are used for secondary sprays. Strengthen the product by spraying it with different pills. The first choice of a larger diameter ball to complete the residual pressure stress removed, the second use of small ball to repair the appearance of finish.
2) Stress shot skills. Stress spray treatment is a sophisticated spraying skills, but it is difficult to use far in large quantities of production, but in recent years because of the rapid development of the automotive industry and stress spray equipment improvement, in the automotive hardware shrapne industry has been a good embodiment. In particular, the combination of stress-reinforced spray treatment and other spray skills, stress spray is usually set at 800MPa at the mercy of the product after the stress spray, the peak of the remaining stress of the commodity can reach 1500MPa, and thus get a high anti-fatigue effect.
