Product Introduction:
Crusher hammer, the accurate definition should be hammer crusher hammer, hammer is one of the core parts of the hammer crusher, arranged in the hammer shaft of the crusher rotor, the hammer in the high-speed operation of the crusher directly hit the material, finally broken into the appropriate material size.
The hammer crusher on the market can be divided into two kinds according to the manufacturing process: casting and forging, but their wear resistance is not the same. Due to the crushing material, the head needs good wear resistance and the handle needs enough toughness, usually alloy steel, high manganese steel, cast steel and high chromium cast iron bimetal composite materials by forging or casting method a molding, with the corresponding heat treatment process is more economical, crusher hammer according to the material can be divided into: High manganese steel hammer head, bimetal hammer head, high chromium hammer head, composite hammer head, big gold tooth hammer head, medium chromium alloy hammer head, hard alloy hammer head. The main factor is the content of silica. Modern industrial technology shows that the use of cemented carbide hammer has a good performance on wear resistance.
Hammer head material
The greater the hardness of the hammer, the greater its wear resistance. To improve the wear resistance of the hammer, it is necessary to increase its hardness, but with the increase of hardness, the impact toughness of the hammer will reduce. Therefore, how to take into account the appropriate hardness and good impact toughness of the hammer is the key to improve the wear resistance of the hammer. Hammerhead commonly used materials are: high manganese steel, high chromium cast iron, low carbon alloy steel. High manganese steel has good toughness, good process property and low price. Its main characteristic is that under the action of large impact or contact stress, the surface layer will rapidly produce work hardening, and its work hardening index is 5-7 times higher than that of other materials, and its wear resistance is greatly improved. But if the towel impact force is not enough or the contact stress is small, it can not make the surface quickly produce work hardening, and the wear resistance of high manganese steel can not play. High chromium cast iron is a kind of wear-resisting material with excellent wear resistance, but it has low toughness and brittle fracture easily. In order to make the high chromium cast iron hammerhead operate safely, people develop composite hammerhead, that is, high chromium cast iron is inlaid on the head of high manganese steel or low alloy steel hammerhead, or the working part of the hammerhead is made of high chromium cast iron, and the handle part is made of carbon steel. The two are combined to make the hammerhead head have high hardness, and the handle part has high toughness. Play the respective advantages of two kinds of materials to overcome the shortcomings of a single material, to meet the performance requirements of hammer head. However, its manufacturing process is complex and strict. Low carbon alloy steel mainly contains chromium, molybdenum and other elements of the alloy structure steel, high hardness, good toughness, the matrix structure of martensite, bainite or bainite + martensite complex structure. The hardness of hammer head is about HRC 45, and the impact toughness is D. 15 J/or higher resistance. Under the same working conditions, its service life is at least I times higher than that of high manganese steel hammer. But the quenching and tempering heat treatment of the hammer is the key. After the quenching and tempering heat treatment, the overall tensile strength is not only required to reach 850 MPa, but also requires considerable plasticity and toughness.
My company has many years of experience in production and sales of composite hammer crusher, the use of special compound casting technology in manufacturing, hammer head struck parts with high chromium cast iron wear materials, hammer handle parts adopt impact toughness good wear resistant alloy steel material, through fission inlay compound casting method, ensure the composite hammer hammer with high chromium wear resistance and impact toughness of the mechanical properties, Compared with manganese steel hammerhead, the service life of the hammerhead produced by our company can be increased 3-5 times.
