Original Abstract

The presented models are a valuable computational tools and accurate simulator for investigating transient phenomena in slab caster operations, and for developing control methods, the choice of an optimum cooling strategy to meet all quality requirements, and an assessment of the heat energy content required for direct rolling. The numerical models of temperature field in the continuous casting are determined via the transient 3D enthalpy balance equation with the Finite Differences Method. The transient simulation is undergoing a non-stop trial run in one operation because steel slabs are produced 24 hours per day. The numerical computation has to take place simultaneously with the data acquisition not only to confront it with the actual numerical model, but also to make it more accurate throughout the process. It enables a multiple increase in the speed with which the temperature field of the continuous casting is computed both with the application of more sophisticated software as well as hardware. As a result of this, it will be possible to monitor the formation of the temperature field in real time within the mould, the secondary and maybe even the tertiary-cooling zones, and also to utilise this information for the optimisation of the control of the caster as a whole as well as its individual parts. There are examples of the application of the models on the temperature field of a real concast slab on Evraz Vitkovice Steel.
