Prediction of Microstructure and Mechanical Properties of Plate in Roller Quenching

Article Preview

Abstract:

Finite difference equations are used for simulation of plate temperature field in roller quenching, and cooling rate in thickness direction is calculated in this paper. Based on improved Maynier model of steel chemical composition and cooling rate, the microstructure constituents and hardness of 30mm thickness pressure vessel steel 07MnNiMoVDR are predicted and calculated with interpolation method. The experimental verification indicates that the simulation results agree well with the experimental ones.
