Centrifugal hammer crusher, crushing its high efficiency, reliable operation, is widely used in metallurgy, mining and cement industries. Dolomite has a Mohs hardness of 3.8 and a high hardness. It is very urgent to study and design a new type of high-efficiency wear-resistant hammer.
The common hammer crusher hammer is made of 4Cr18Ni2Mo and has a hardness of HRC35. During the casting process, carbon chromium forms a wear-resistant structure in the steel matrix. Although this material has certain wear resistance, the coarseness of the microstructure of the microstructure results in low impact toughness and a certain crack on the substrate. Function, so in the operation process, when the hammer crusher tells the rotation, the hammer head and the working medium violently collide with each other, the hammer head is easily broken.
The hammer crusher breaks the material by causing the hammer to generate a large inertia by high-speed rotation. Different materials have different effects on the wear of the hammer. Since the hardness of dolomite is higher than that of limestone, after the dolomite is changed, the wear of the hammer is accelerated and the service life of the hammer is sharply reduced.
To improve the wear resistance of the hammer, it is necessary to increase its hardness. However, as the hardness increases, the impact toughness will decrease. This is a contradiction. Therefore, how to balance the hardness of the hammer and the good impact toughness is improved. The key to the wear resistance of the hammer.
According to the principle of bionics, Red Star machine experts combined with the working characteristics of the hammer crusher and the characteristics of dolomite, designed and manufactured a composite hammerhead, that is, the alloy with higher hardness is embedded in the matrix with higher toughness. The composite hammerhead should have a high toughness and hardness in the outer softness.
Steel hammer in material selection (e.g., 1045 steel) with high chromium cast iron (e.g. Cr20-28) organic compound, using the solid - liquid composite casting sand, high chromium cast iron high carbon ferrochrome, molybdenum, copper, Scrap steel and other ingredients, in the smelting process, the Cr, C, Mo and other components are optimally controlled to carry out intensive smelting.
Aluminum High-strength Thin Sheet
Aluminum High-strength Thin Sheet is one type of Aluminum Sheet which has high strength but with the thin thickness.It is good in performance condition which requires high strength.Regularly when the thickness of the aluminum is reduced,the strength of the same is also reduced.The main difference is from a special heat treatment process which enables the thin aluminum sheet with a high strength.So in the clients end,it is possible to use less aluminum material to produce the same product with same strength.The technology innovation is good for reducing the usage of the energy which also reduced the carbon oxidation.We hope to bring better future for our next generation.
