Possibility of FeSiCr alloys production, with low content of carbon, in industrial conditions depends upon various factors like temperature of the solution, refining time, chemical compositions and others. In order to identify the evolution and behavior of solid inclusions in the solution, laboratory tests for alloys at high temperatures of 1400-1500 °C have been carried out. For identifying the trajectory of inclusions, numerical simulations, in industrial conditions, have been performed for velocity and temperature distribution in a ladle furnace. Microscopy identification of selected inclusions, important from industrial refining viewpoint, has also been performed. The paper summarizes results of theoretical calculations and laboratory tests for ultra low carbon (ULC) FeSiCr alloys.Keywords: Metallurgy, FeSiCr-alloys, refining in ladle, numerical simulation, temperature, velocity profile
