Hammer during operation, the material needs to withstand the impact force between the friction and speed to deform, if used in the reversible crusher, hammer edges on both sides will be ground into a smooth circular arc surface. Hammer crusher in the early work surface changes shape classification for small hammer, hammer wear mainly by the impact of materials in order to produce a positive force impact crater shaping metal surface deformation. When the hammer's face in solitary after ground round, this time the surface force change. Thereby increasing the hardness of the hammer, hammer wear resistance can be improved, thereby reducing the impact of wear and improve the toughness of the material helps to suppress the generation of cracks and expansion will help reduce friction and wear. Therefore, the characteristics of a small hammer, the choice of what kind of wear-resistant material is the basic way to improve the life of hammerhead. Hammerhead work requirements, different heat treatment process for preparing a low alloy steel large hammer performance ladder change, +560 825 degrees Celsius quenching and tempering can better ensure the hammer installation site performance. The hammer blow to the site hardness 50 ~ 52HRC, impact toughness greater than 30J / cm2: the hardness of the installation site is HRC25 ~ 37, toughness greater than 100J / cm2. Large low-alloy steel hammer production process is simple, hit parts of the high initial hardness, compared with high manganese steel, the material of high hardness, low-impact action conditions, can significantly improve the life of the hammer; and bimetal composite casting Hammerhead Hammerhead small compared to the large hammerhead good toughness, can ensure the course is not broken, and enhanced the safe use of the hammer.
