The model was used to simulate the air cooling process in slabs of two similar steel grades, one with and the other without boron. A 3D thermomechanical finite volume model with coupled heat transfer, stress, and phase transformation calculations was developed in the OpenFOAM platform to investigate the temperature history, phase evolution, and stress development during cooling. ![]() These problems can arise during the post-casting cooling process because boron addition changes the phase transformation behavior of steel. Boron-containing steels have good hardenability in wide applications, but may exhibit defects such as transverse corner cracks in slabs after continuous casting.
