Composite hammer hammer crusher is mainly used in our production brings certain benefits, then in order to give you a better understanding of it, here are some more knowledge about their simple types, we hope harvest. 1, forging hammer forging hammer crusher with high-quality steel train wheels (material 65Mn hammer parts manufacturers, impact resistance, toughness, wear resistance, not easy to break) by forging machinery for metal forging billets repeatedly make which is deformed to obtain a certain mechanical properties, a certain shape and size, through a special quenching in the method, to ensure composite hammer working area to obtain a high hardness, high wear-resistant properties. 2, carbide carbide hammer hammer compared with other materials, with a higher hardness, flexural strength and impact resistance to thermal fatigue humanoid, good hot hardness, low cost, easy to solve the high-manganese material cracks appear, Desoldering, chipping off the block and so on. High chrome hammer is high chromium cast iron, carbon steel as raw material, the use of cast-process manufacturing high chromium cast iron / steel bimetal composite hammer. Then as we expand on the need for pre-heating device is designed de zshi. Due to the high chromium cast iron metal liquid at room temperature and high temperature carbon steel combination of molding, the total lack of heat, high chrome hammer difficult to achieve metallurgical bonding material interface. There is a big stress material interface, combined with the strength of the interface is difficult to achieve test requirements hammer parts prices, significantly affect the microstructure and properties of the sample. Therefore, the test of the core material is preheated, so preheated core combined with liquid metal forming, so that the two achieve a good metallurgical bond to reduce residual stresses generated hammer parts, improve the bonding strength. Therefore, before entering the liquid-solid core material effect, should be designed to a preheating means for preheating the core material to a certain temperature. In the past mostly used for core preheat oven to finish, when heated to the required temperature, out into the cavity, and then close the box pouring molten metal. The whole process due to the long heating time, the heating element is easily oxidized. Meanwhile, preheat removed from the furnace to the casting, it is generally difficult to control the middle of the time, leading to the actual temperature changes before preheat a large complex, can not guarantee the quality of stable complex interface.
