Abstract: Al2O3-C unfired slide plate is widely used as the functional refractory materials of the continuous casting, and the metal binding diamond tools play a key role in the grinding of the slide plate. In this work, Fe-Ni-Cu-Sn metal matrix and diamond tools were prepared by hot pressing sintering. Firstly, the effects of sintering temperature, holding time and sintering pressure on the mechanical properties of diamond tool matrix were studied to obtain optimal parameters of sintering process needed by the subsequent preparation of diamond tools. Secondly, the effects of different diamond abrasives on the mechanical properties and performance for grinding unfired slide plate processing tools were studied. The optimal parameters of diamond abrasives in diamond tools for grinding unfired slide plate was obtained by studying the relationship between the concentration, particle size, grade of diamond and the grinding efficiency, life and sharpness of the processing tools. The bonding state of the matrix of the diamond tool and the diamond abrasive and the wear of the diamond were analyzed by SEM microstructure. The results show that the optimum sintering process parameters of diamond tool matrix are sintering temperature, holding time and sintering pressure of 785 ℃, 170 MPa and 240 s, respectively. The optimal selection of diamond abrasive in diamond tools is that the diamond concentration is 25%, the particle size is 45/50, and the grade is SMD35.
