The main purpose is to hammer hammer wear and abrasion resistance to the limit. The traditional consumption particularly large hammer, hammer crusher such as mining and other industries in the battlefield and used every day for a lot of work which increases the cost. So for some broken grinding class industry they want to hammer longer usable, so not only can increase the efficiency of the crusher, and can effectively save costs. Hammer crusher wear-resistant high speed when a direct blow to the material, eventually breaking into the appropriate material particle size, the hammer is one of the core parts of hammer crusher, arranged in the hammer crusher rotor shaft, hammer crusher direct hit at high speed material, the extent of wear-resistant hammer is not the same, the head of the need for good wear resistance and toughness of the shank and need adequate, good performance with carbide hammer is a hammer on the wear resistance One of the important parts of the crusher. Depends on the microstructure and properties of the hammer chromium and carbon content, due to the affinity of carbon and chromium is greater than the affinity of iron and carbon, thus forming a series of ferrochrome stable compounds. High High chrome hammer hardness, wear resistance, and has been widely used. Because of chromium and carbon content of the hammer than the higher, but also the grain boundary chromium carbide forming elements mesh, resulting in large amounts of eutectic carbides at the grain boundaries continuous distribution, but also for the twinning matrix substructure of martensite, This distribution of continuous brittle carbide network structure on rigid substrate grain boundary embrittlement caused hammer toughness inadequate reserves, affecting its scope of application. How to improve the toughness of the hammer, has become an important issue for all manufacturers. As a wear-resistant material, must be required to have a high hardness. But in the process, only the pursuit of the wear material hardness and toughness of the material neglect, it will inevitably lead to the effectiveness of bimetallic hammer hammer flaking during use, and even premature rupture phenomenon. Because of the wear process will be affected by a variety of elements, and therefore the total hammer design ideas to how to sell bimetallic hammer hammer in ensuring a certain toughness, the hardness as high as possible, taking into account the course material properties will change, not only from the static performance hammer to consider. Because chromium can improve the high temperature oxidation hammer and corrosion resistance, so the hammer has excellent heat resistance and corrosion resistance. The difference between the hammer and the stainless steel is its high carbon content, the mechanical properties, especially low plasticity and toughness. But because it contains a lot of high hardness carbide, so its abrasion and wear resistant materials in particular, the performance is excellent. In addition, the hammer also has good resistance to oxidation and corrosion resistance, wear-resistant hammer often as high temperature or corrosive environments.
