Hammer crusher is widely in mining, metallurgy, cement and building materials and other industrial applications, and as a key component hammer crusher is one of the wearing parts composite hammer, its consumption is great. For a long time, in order to improve the wear resistance of the hammer, hammer prolong life and reduce downtime and maintenance time equipment manufacturers composite hammer, hammer it from the material aspects of change do in-depth research. 1, the use of solid-liquid two-metal composite casting method for manufacturing a high vanadium high speed steel / carbon composite hammer, hammer handle studied under different processing conditions of complex cases; 2, the results show that after the hammer handle complex after pickling performance composite hammer to good effect, to achieve metallurgical bonding; 3, while the hammer handle rust through mechanical means or no treatment, composite hammer hammer handle and bad. After the pickling process produces high vanadium high speed steel composite hammer hardness to meet the requirements, with favorable results. High manganese steel hammer crusher hammer is the earliest, because of work hardening characteristics and suffering attention. But in recent years, because many conditions under conditions of high manganese steel hammer hardening function and can not be fully manifested, causing far less than the design life of its life, causing a great deal of money to waste resources, thus, complex Hammerhead was born. High chrome composite hammer using today's most advanced composite casting process, using the best wear resistance hammer high chromium cast iron, hammer handle using the toughness of the strongest steel composite hammer classification, let thaw for toughness and wear resistance one, so that the product not only wear and fracture, is the perfect combination of steel and iron, the product has good wear resistance, impact resistance, safe and reliable overall performance, service life is high manganese steel forging hammer or hammer 4 times.
