MATHEMATICAL AND ANALYTICAL ANALYSIS OF THE INFLUENCE OF TECHNOLOGICAL FACTORS AND PARAMETERS ON THE EFFICIENCY OF THE PROCESS OF DESULFURIZATION OF CAST IRON WITH MAGNESIUM

Abstract. The purpose of the work was to make a mathematical and analytical assessment using the methods of mathematical statistics and modern computer application programs of the unit effect of temperature, initial and final sulfur content, depth of the liquid bath and mass of cast iron, mass of ladle slag, intensity of magnesium supply, consumption of gas carrier and freeboard in a ladle on the effectiveness of the desulphurization process of cast iron with magnesium. The comparison of the obtained results of mathematical and statistical processing with the results of a theoretical assessment of the influence of technological factors and parameters on the efficiency of the magnesium iron desulfurization process made it possible to assess the presence and potential opportunities for increasing the efficiency of the iron desulfurization processes implemented in different initial conditions. In order to improve technological processes of desulfurization of cast iron with magnesium, it is recommended to control and, if necessary, adjust the chemical composition and parameters of ladle slags to increase their basicity and sulfide capacity. The expediency is shown, on measures and expansion composed bank of actual data, continue their mathematical and statistical processing for clarification purposes single impact on efficiency process desulfurization cast iron initial conditions and parameters processing.

Key words: desulfurization, cast iron, statistical analysis, ladle, slag, mixer.
