Abstract

A study was conducted to develop a thermomechanical model of the solidifying steel shell in the beam blank casting mold using realistic boundary conditions and material properties. The model predictions were compared with plant measurements to demonstrate significant accuracy for the optimization of mold taper. The computational model solved the coupled temperature and stress and deformation equilibrium equations in a beam blank caster. Separate models simulated thermal distortion of the mold, including the complete complex three-dimensional geometry of the copper plates, water box, and thermomechanical behavior of the solidifying steel shell as it moved through the mold. The model also alternated between solving the transient energy equation and the small-strain thermomechanical equilibrium equations. Investigations also revealed that thermal strains arose due to volume changes caused by temperature differences and phase transformations.
