6.Advanced heat treating process
Heat treatment is the key step of the whole production process.In the R&D practice,Dongfang invents
Application Method for Warm Period Timing Quenching in Grinding Materials Heat Treatment and other skills.
Machine oil is used to quench,making workpiece heated evenly,promoting the first formed carbide decompose
once again and then forming uniformly distributed reticular carbides in the matrix.
Due to the unique heat treatment process, grinding medias obtain the required hardness and metallurgical
structure,and the hardness gap between core and surface is less than 1.5 HRC.
