Abstract:Based on the results of sawing tests with matrixs of four formulas,this paper analyzed the nelationship between matfrix wear resistance and the hardness of matrix with high temperature,put forward a high temperature softening concept for the matrix,and on the basis of measuring the high temperature softening peint of matrix,andlyzed the relationship between matrix wear resistance and the high temperature softening point of matrix so as to direct the design of saw blade matrix
