First, the optional alloy hammer specifications should be appropriate. Each model of industrial machinery are both prescribed alloy hammer in order to apply the production needs of different instruments, of course, there are differences between types of alloy hammer, so the need to recognize the choice model. If you choose the wrong type, alloy hammer and machine can not be good butt, loosening up the interface or agents may occur. If the connector is loose, alloy hammer when using alloy hammer is likely to fall off suddenly introduced, it is very easy to accidentally injure staff passing, it is very dangerous. If the interface is too tight, it can cause rupture cram into a machine at the interface of machine damage can be imagined. If you buy the wrong type alloy hammer, do not impose the use of convenience, must be replaced with the corresponding correct model. Meanwhile alloy alloy hammer used is different alloy hammer performance, rigidity of each different material, work intensity will be different. Be sure to select the appropriate job-strength alloy material adapted hammer. 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 alloy hammer manufacturers, 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 stress, and to 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.
