"The paper is devoted to verification of parameter-setting of a numerical simulation of filling and solidification of a 90-ton heavy steel ingot in the ProCAST simulation programme. The aim of numerical modelling realized under the conditions of the Department of Metallurgy and Foundry and Regional Materials Science and Technology Centre (RMSTC) at VSB-TU Ostrava is the optimization of the production of heavy steel ingots produced in V\u00CDTKOVICE HEAVY MACHINERY a.s. (VHM). Input parameters of computation were determined by the real conditions of parallel experimental casting of a 90-ton steel ingot. Material properties of the individual components of the ingot casting system were defined by the COMPUTHERM calculating module, by selection from own database of ProCAST, using datasheets of refractory materials of the manufacturer, and finally checked by calculation of the equations generally used to determine liquidus and solidus temperatures. To obtain more complete information about the temperature fields of the ingot casting system, the process of filling and solidification was monitored using thermal imaging cameras. Primary results of the numerical simulations were compared with the results of thermography measurement and with the real time of filling and solidification. Based on the comparison of the results, the initial temperatures of the casting system and heat transfer coefficients were modified. The character of the filling and the RUN PARAMETERS were also changed. Now, the attention is also focused on the verification of liquids and solidus temperatures of steel, and heat capacity of mould material using methods of thermal analysis."@en . "Klus, Petr" .
