“…The time and location function of the heat flux is used as the thermal boundary condition instead of the heat transfer coefficient in the simulation of the quenching process. [ 18 ] This method was first applied to the gas quenching process. Douce and Wang combined gas flow simulations and solid heat transfer calculations to predict the temperature history and final state of the workpiece, highlighting the ability of numerical simulations to analyze complex gas flows and predict temperature.…”

In the numerical simulation research on quenching, the heat transfer coefficient is an important input parameter. However, owing to its complexity and various influencing factors, the measured results are not universal and will significantly increase the simulation complexity and error. This article proposes a new numerical simulation method for quenching processes by extending the simulation domain and introducing the coupled heat exchange between the liquid quenching medium and workpiece, replacing the role of the heat transfer coefficient in the numerical simulation. The method is validated through experimental studies on 1045 steel rod quenched in water, with the maximum relative errors of the simulation results compared to the experimental results being 3.6%, 9%, and 5.1% for hardness, cooling curve, and residual stress, respectively. Furthermore, the article investigates the effect of different flow parameters of quenching media on the quenching effect. Under the studied conditions, the 1045 steel rod has the lowest risk of cracking and the highest hardness value when quenched in water at 50°C. The proposed method improves the universality and convenience of numerical simulation for the quenching process. and can be used to guide the formulation of quenching process parameters when the heat transfer coefficient is unknown.This article is protected by copyright.
