The composite Stone Crusher divides the hammer head into two parts, the hammer handle and the hammer end. The hammer handle and the hammer end are made of different materials. First, the hammer handle or the hammer end is prefabricated with a material, and then the pre-manufactured hammer shank or hammer end is placed in the mold to cast another liquid metal for casting. A portion of the hammer is prefabricated and then cast to form another portion of the hammer. The prefabricated hammer handle is generally made of carbon steel. The commonly used carbon steel is ZG35 and ZG45. It can also be directly bent into a hammer handle by using the steel profile, and then the hammer end is cast. The hammer end material is generally made of high chromium cast iron. Another method is to pre-manufacture the hammer end and post-cast the hammer handle.
The material selection of the hammer handle and the Crusher Machine, one combination is the material selection of the hammer handle, ordinary carbon steel such as ZG25, ZG45, the hammer end is made of high chromium cast iron; the other combination is the hammer handle is high manganese steel, the hammer end is high manganese steel. The mother is inlaid with a hard alloy block. 2, two-liquid bimetal composite casting hammer two-liquid bimetal composite casting method is to first cast a certain thickness of the first metal liquid into the mold, while pouring molten high-temperature protective agent to prevent the height of the joint is certain The second molten metal is poured after the time interval. High chromium cast iron + high manganese steel adopts the whole lost foam vacuum suction casting process. The steel structure which is cleaned and dried by dilute hydrochloric acid is placed in the prepared EPS pattern. The material is Q235A, the shape is box-shaped structure, one end is open, and the casting is required to be high. When chrome cast iron is not melted through, first cast high chromium cast iron and then cast high manganese steel.
