Casting and forging hammer crusher which is more wear-resistant casting: the metal is smelted to meet certain requirements in liquid and poured into the mold, the cooling and solidification, after the entire process to obtain clearance of a predetermined shape, size and performance of the casting process process. Rough casting due to the near-forming, and to achieve a small amount of free machining or processing purposes to reduce costs and to some extent, reduce the time. It is one of the basic technology of modern manufacturing industry. Forging: mechanical pressure by forging the metal blank to produce plastic deformation to obtain a certain mechanical properties, shape and size of the forging certain processing methods. Liquid-liquid two-alloy composite casting: is leading the latest technology in the industry, using two kinds of pressure-type liquid-liquid alloy centrifugal composite casting, hammer part of high hardness alloy steel hammer handle part excellent toughness alloy steel, the perfect combination of the two materials, solve a single alloy material easily broken hammer handle high hardness, toughness, wear really disadvantage, wear is high manganese steel casting and forging track 3-6 times. Forging hammer crusher, the metal is heated up to a temperature of 700-1300 ℃, by forging mechanical pressure on the metal blank to produce plastic deformation to obtain a certain mechanical properties, shape and size of the forging certain processing methods. Hammer crusher which is more wear-resistant, stable to be sure it is forging performance, low cost, simple technology, casting hammerhead technology complex and difficult to control small hammer performance, so sometimes casting hammerhead might as well wear a small forging hammer Hammer ex-factory price, but qualified casting forging hammer hammer is 5 times life. Generally small hammer, hammer hardness greater abrasion resistance is also greater. To improve the wear resistance of the hammer, it is necessary to increase its hardness, but with the hardness, impact toughness is reduced hammer. Therefore, 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, good technology, 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 5-7 times higher than other materials, greatly improved wear resistance. But if the impact force is not enough towels or small contact stress, the surface can not quickly produce wear work hardening, high manganese steel can not be fully realized. High chromium cast iron is an excellent anti-wear properties of wear-resistant material, but low toughness, prone to brittle fracture. In order to make high chromium cast iron hammer safe operation have been developed composite hammer, high chrome cast iron cast in the upcoming high-manganese steel or low alloy steel hammer head or hammer work part of the high chromium cast iron hammer handle part carbon steel, the two compounded, so the hammer head has a high hardness, and the hammer shank having a high toughness parameters small hammer, give full play to their respective advantages of the two materials, and to overcome the shortcomings of a single material, the use of performance to meet the hammer Claim. But its complex manufacturing process, process requirements more stringent. Carbon steel alloy structural steel mainly containing chromium, molybdenum and other elements of high hardness, good toughness, the matrix organization martensite, bainite or bainite + martensite composite structure. Hammer hardness of about HRC 45, impact toughness d. ≥15 J / resistance. Under the same operating conditions, the service life of high manganese steel hammer, at least more than I fold increase. But Hammer transfer of heat treatment is the key, quenching and heat treatment requires not only the overall tensile strength of 850 MPa or more, and requires considerable plasticity and toughness.
