NUMERICAL MODELLING OF METALLURGICAL PROCESSES - CASTING AND SOLIDIFICATION OF STEEL

From 2011 the teaching licenses of simulation program QuikCAST (SW QC) are available in the Laboratory of Modelling of Processes in Liquid and Solid Phases (as part of the project Regional Materials Science and Technology Centre) in Department of Metallurgy and Foundry at VSB – Technical University of Ostrava. The mentioned software allows 3D, fully dimensional numerical calculation of steel melt flow dynamics during the filling of a cast iron mould and the simulation of subsequent solidification of steel with the possibility of the prediction of ingot defects, as well as the residual stresses leading to cracks and rupture. Within the solution of the project FRVS No. 1610/2012/G1, the aim is to implement practical training in SW QC into the courses Modelling of Metallurgical Processes and Modelling of Processes. The implementation should lead to the creative development of students, and to the expansion of their theoretical and practical knowledge in numerical modelling in order to continue using the gained experience in practice. Primarily, the attention is focused on understanding the basic principles of geometry modelling of casting systems, grid generation, and definition of calculation parameters and graphical evaluation of results.
