Advantages and characteristics of bimetal composite hammer head

Why design bimetal composite hammer head? Hammer crusher is widely used in metallurgy, mining, building materials, electric power, coal, cement and chemical industries and other crushing equipment, crusher hammer head is its key but easy to wear accessories. Before the common manganese steel hammer and forging hammer on the market are made of a single material, which cannot meet the wear resistance and toughness at the same time. In order to improve the service life and stability of hammer crusher hammer, improve production output, reduce production cost, long-term consideration is also to reduce the waste of wear-resistant materials. Therefore, bimetal composite hammer with both wear resistance and toughness emerged at the historic moment. Bimetal composite hammerhead has two forms, one is solid-liquid composite hammerhead (cold composite hammerhead), one is a double liquid composite hammerhead (hot composite hammerhead). The difference is mainly composite surface, double liquid composite hammer because of the casting process of two kinds of liquid are in high temperature liquid, so the composite surface is more stable and firm, after a complex heat treatment process, the overall performance is stable, not easy to break the hidden trouble from the composite surface.
The bimetal composite hammer head adopts high chromium cast iron as the main raw material of the hammer end working surface. At the same time, in order to increase the hardenability and hardenability of the material during heat treatment, metal elements such as molybdenum and nickel are added. Greatly improve the service life of the hammer head. The handle of the hammer is made of high grade cast steel with high toughness, which ensures the impact resistance and toughness of the installation part and is not easy to fracture. The appearance of bimetal composite hammer head greatly reduces the use cost of hammer crusher, and adds to the advantage of high yield of hammer.
