The casting machine of the shock excitation and rotation comprehensive effect was obtained by the improvement on the basis of the traditional casting technology. Mine manganese steel hammer was cast by the casting machine of the shock excitation and rotation comprehensive effect. The manganese steel hammer was analyzed by the microstructure and wear resistance. The casting mechanism of the casting machine of the shock excitation and rotation comprehensive effect was further discussed. The experiment result showed the cast manganese steel by the shock excitation and rotation method had the advantages of the grain fine and uniform, good wear resistance. Comparing to the traditional technology, the new casting technology could extend the service life of the casting manganese steel. © (2013) Trans Tech Publications, Switzerland.
