This works presents some examples of modelling technique for the numerical analysis of steelmaking components under thermomechanical loads. The proposed technique fits an “industry oriented” approach, in which several complex phenomena such as plasticity at high temperature, thermal transient, phase transition are addressed by a simplified, yet effective modelling. Numerical techniques are developed with a special focus on reducing the model complexity and the computational time, as well as to use simplified material models that require a fewer number of material parameter to be identified from experimental tests. The examples discussed are: an anode undergoing partial melting under operative conditions, a hot mill work modelled by onedimensional harmonic finite elements, a copper mold for continuous steel casting used to choose a suitable cyclic plasticity model.
