| Abstract: | In allusion to the working condition and structure characteristics of large impact crusher,we developed ultra high chromium cast iron plate hammer with high comprehensive wear-resisting performance.The best heat treatment process of plate hammer is 1020 ℃ high temperature quenching+400 ℃ high temperature tempering.The structure formed after quenching and tempering consists of tempering martensite + eutectic carbide M7C3 +secondary carbide+residual austenite.Its service life is 3 times more than ordinary high manganese steel. |
