New Type of Bimetal Composite Casting and Welding Connection Square Hammer

The brick crusher hammers were used in factory, which wear-resisting was poorer. According this phenomenon, the single structure was designed in symmetrical fission structure. Firstly, high chromium cast and low alloy steel were casted into half of the bimetal hammer head, then two new type bimetal hammer head were connected into a whole body by the welding technology. The high abrasion resistance and impact toughness of bimetal composite material played an important role in process of use and the service life was improved effectively, which provided a new way of thinking for complex compound casting. The results showed that the new type of bimetal composite casting and welding connection hammer production's cost was 1.5 times of high manganese steel hammer, but the service life was improved 3~5 times. Low alloy steel and high chromium cast iron composite layer was a metallurgical combination, and the whole strength was good and no fault phenomenon in the using process after welding.
