Numerical Simulation and Experimental Verification of the Quenching Process for CM690 Anchor Chain Steel
A numerical simulation model describing the steel quenching process was developed using the finite element software COMSOL Multiphysics 6.3. The temperature and microstructure field evolution of CM690 anchor chain steel during Jominy end-quech test were systematically simulated, and the simulation results were verified through experiments. The results show that the developed model can accurately predict the temperature distribution and microstructure evolution of the test steel during Jominy test. During Jominy end-quench test,the specimen exhibits quasi- one-dimensional heat transfer characteristics , and the temperature field changes are mainly influenced by the comprehensive heat transfer coefficient at the interface. As the distance from the quenched end increases, the cooling rate gradually decreases, resulting in a gradient distribution of the microstructure: the martensite content gradually decreases and is mainly concentrated in the 0 mm ~ 20 mm range; bainite appears in the area from 9 mm to 40 mm away from the quenching end; pearlite is distributed in the 70 mm to the top range; and ferrite forms in the 25 mm to the quenching top. Furthermore, the observed microstructure of the dilatometric specimens at different distances from the quenched end is highly consistent with the simulation predictions. The Vickers hardness values measured for Jominy test specimen and the dilatometric specimen also show the same trend of change, further verifying the reliability and applicability of the model.
