In this regard, the microstructure and hardness for each arbitrary point within the mill liner's bulk could be predicted based on using the CCT diagram of Cr-Mo steel and superimposing the cooling curves. Moreover, the results of the simulations and the industrial data were compared to prove the validity of the simulation. The findings showed that the microstructure of pearlite, duplex pearlite+bainite and martensite were achieved by quenching, using air fan, oil and water, respectively. The simulated cooling curves were consistent with the measured cooling curves, and simulation could be a promising method for designing the heat treatment process for mill liners.
