The hardness and wear resistance of the saw blade are directly proportional to the hardness and wear resistance of the high frequency quenching equipment with super audio frequency. To improve the service life of the saw blade, it is necessary to detect the hardness of the saw blade and select an appropriate value. The quenching temperature of the saw blade is 900℃, the material used for the saw blade is 65Mn, the induction quenching heating temperature of the cold saw blade is 810～850℃; the induction quenching heating temperature of the hot saw blade is 790～830℃. The depth of the hardened layer on the surface of the part needs to be determined according to the service conditions of the part. The depth of the hardened layer of the cold saw blade is between 2mm and 6mm, and the hardness value is generally between 53 and 58HRC. The lower limit can be removed; the depth of the hardened layer of the hot saw blade Generally between 1-2mm and the hardness value is 58HRC.
