Heavy Rail Spray Quenching Wind Heat Stress and Residual Stress Analysis

Abstract:

Calculating the stress field distribution of the different working conditions which are the heating, heat preservation, forced cooling and so on, analyzing the impact of the quenching time on stress field, the result of calculation is more close to 3 d work piece quenching process. The result of the experiment and calculation results are analyzed and compared. Simulation results are in good agreement with the test result, spray quenching wind produces the smaller residual thermal stress and avoid the deformation and cracking of heavy rail. Provide the basis for setting reasonable heavy rail quenching process for the actual production.
