The paper is devoted to new experiences with the setting of a numerical simulation of filling and solidification of a 90-ton steel
ingot in the ProCAST simulation programme. The aim of the numerical modelling realized under the conditions of the
Department of Metallurgy and Regional Materials Science and Technology Centre (RMSTC) at VSB-TU Ostrava is the
verification and optimization of the production technology for the heavy-steel ingots produced in VÍTKOVICE HEAVY
MACHINERY a.s. The input parameters of the computation were determined with the real conditions of casting a 90-ton steel
ingot. The ingot geometry was created in the CAD system SolidWorks. Before the computational grid generation of finite
elements in the Visual-Mesh module, the geometry was subjected to an analysis of the topology. The material properties of the
individual components of the ingot-casting system were defined with the Computherm calculating module selecting the
materials from its own database of ProCast. In addition, the thermodynamic properties were determined by using the datasheets
of the refractory materials of the manufacturer, and finally checked with the equations generally used to determine liquidus and
solidus temperatures, density and enthalpy, etc. The boundary conditions and the heat transfer were also defined. In parallel with
the numerical simulation, the operational experimental casting of a 90-ton ingot was carried out. To obtain more complete
information about the temperature fields of the ingot-casting system and of the data about the values of the heat flow, the
process of filling and solidification was monitored by using thermal imaging cameras. The conclusion summarizes the main
knowledge obtained on the basis of the primary results of the computation and gives a guideline for further research.Web of Science46440239
