Abstract

The paper is devoted to verification of solidification of continuously cast round steel billets with a diameter 400 mm 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 continuously cast steel in ArcelorMittal Ostrava a.s. The temperature field, the thickness of the solidified shell, the metallurgical length and the porosity were predicted under different boundary conditions of continuous casting. To achieve mentioned results, the same type of the geometry, a computational mesh and also a definition of the numerical model were used. The paper describes the pre-processing, processing and post-processing phases of numerical modelling. The advantages and disadvantages of mentioned methods are discussed and possible future developments are outlined.

Keywords: Steel, continuous casting, numerical modelling, metallurgical length, porosity
