DEVELOPMENT OF NOMOGRAMS AND CALCULATIVE MODELS FOR SPECIFIC MAGNESIUM СONSUMPTION AND SULFUR CONTENT IN IRON UNDER DIFFERENT CONDITIONS OF INJECTION HOT METAL DESULFURIZATION

Abstract. Built and put into operation experimental industrial and industrial installations and cast iron desulfurization departments ensured a reduction of sulfur content in cast iron to 0.005-0.010% in industrial conditions. The purpose of the work is to reliably predict the calculation of the necessary consumption of magnesium from various conditions – the initial sulfur content, the mass of cast iron and the given final sulfur content to ensure the reduction of desulfurization costs. In addition, it is important to predict the current content of sulfur in cast iron depending on the consumption of magnesium in order to increase the reliability of the achieved content of sulfur in molten iron. The developments carried out to assess the regularities of the processes of out-of-furnace desulfurization of cast iron by monoinjection of granular magnesium made it possible to obtain calculation models for the assessment of existing and newly built capacities for desulfurization of cast iron in ladles of different sizes (40-350 t) at different initial sulfur contents in cast iron (0.02-0.07 %) and requirements for the final content of sulfur in cast iron (≤0.002-0.015%). Calculation models are presented.

Key words: desulfurization, cast iron, ladle, models, magnesium consumption.
