Generally used counterattack and hammer crusher, two key components of the board hammer crusher and hammer, safety, reliability, wear resistance and service life performance, impact crusher production safety, uptime and production costs. Cast microstructure of high manganese steel hammer and hammer austenite and carbide, after water toughening treatment for a single austenite, with high toughness, in the strong impact, the surface can produce forging machining hardened layer How much money playing the hammer, so that it has good wear resistance, hardness but lower limestone, forged under the hammer price in the low-impact stress, high manganese steel hammer and hammer can not form a sufficient surface hardening layer, so the work is not high enough surface hardness, wear faster. Further, when the high manganese steel below 300 ℃, its internal organization around grain boundaries will have to re-precipitation of carbides forging hammer, so that more complete dense matrix crack. Thus, the hardness is lower than the carbide substrate is first worn, so that the carbide stand out; and crushed carbide stand out or fall off and lose the protective effect of the matrix, the matrix further wear. So the cycle, resulting in high manganese steel hammer and hammer were soon worn short life. With the upgrading of the construction industry, building materials, may also need to tie it to upgrade. Common hammer crusher wear also need to increase, then how can strengthen its wear it? In general, the greater the hammer hardness are greater wear resistance. To improve the wear resistance of the hammer, it is necessary to increase its hardness, but with the hardness, impact toughness is reduced hammer. So the question is, how to balance the hammer suitable hardness and good impact toughness is the key to improve the wear resistance of the hammer. Hammerhead commonly used materials are: high manganese steel, high chromium cast iron, carbon steel. High manganese steel toughness forging hammer manufacturers, technology is good, low price, its main feature is the role of the larger impact or contact stress, the surface layer will quickly produce work hardening, work hardening exponent than other materials high 5-7 times the abrasion resistance is greatly improved. But if the impact is not enough to use towel or small contact stress, do not make the surface rapidly produce wear work hardening, high manganese steel can not be fully realized.
