Abstract: The paper describes the present conventional process of bimetal compound casting technology and their merits and defects, and on this basis, analyses the trend and progress in the research of the bimetal compound casting for crusher head. It is considered that bimetal compound casting technology is an effective means for improving the integral performance of crusher head, and disperse imbedding and theological compound represent the development orientation of compound hammer head. Correspondingly, the study of compound criteria, material compatibility and interface integration will be the major points of the research.

Key words: Crusher head, Bimetal compound, Casting process
