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.
