The paper is devoted to analysis of the utilization possibilities of suitable similarity criteria for physical modelling of transfer processes between metal and slag including the presence of a third gaseous phase. The attention is also devoted to the modelling results and to the simulation methodology of the element transfer in the ladle. The modelling was done on a physical model of the ladle constructed on a geometric scale of 1: 9 located in the Laboratory of Physical and Numerical Modelling at the Department of Metallurgy, Faculty of Metallurgy and Materials Engineering. First, the discussion deals with the option of converting the operating variables to laboratory values, and vice versa. The suitability of the chosen similarity criteria for individual methodology of the simulation is also discussed. The results of the physical modelling of the transfer and homogenization processes are used as input data. The discussion is also focused on factors affecting the intensity of these processes under real operating conditions of the secondary metallurgy equipment. From analysis of the results, the final recommendations lead to the further expansion of the physical modelling techniques and to the results complementation by the data obtained from the numerical modelling. The Department of Metallurgy together with the Department of Physical Chemistry and Theory of Technological Processes are involved in the Regional Materials Science and Technology Centre project, Research Program No. 6. In this project, these workplaces created the Laboratory for Modelling of Processes in the Liquid and Solid Phases. The newly purchased equipment and existing human and material laboratory facilities will provide new opportunities for conducting applied research not only in the field of transfer and homogenization processes in the ladle.
