Hammerhead is one of the important parts of the crusher. Microstructure and Properties of the hammer depends chromium and carbon content of the big hammer, 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 big hammer hammer price, has become an important issue for all vendors. 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 hammer flaking effectiveness 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 idea is to ensure that the hammer in case there is a certain toughness, hardness as high as possible, taking into account the performance of the material in the course of 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 uses big hammer, 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. In order to improve the high chrome hammer surface refractoriness, chemical stability, anti-metal erosion resistance, sticky sand and other properties and applied in its core surface mold cavity or an overlay material. Its specific role is as follows: 1, to reduce the surface mechanical and chemical sticky sticky sand sand; 2, to reduce the surface sand and washed sand; 3, to improve the surface properties and internal quality high chrome hammer.
