Kysliakov V. Improving the technological basis for the preparation of pig iron for smelting low-sulfur oxygen steel

Physical - chemical regularities of processes occurring during hot metal desulphurization with granulated magnesium in the "metal-slag". Estimation of parameters and the development requirements of the process of preparation for converting iron smelting, ensuring efficient and effective use of pig iron for steel production with different sulfur contents. Experimental studies of physical and chemical modeling, optical and scanning microscopy. Determined the influence of chemical composition on the technological properties of molten slag on the basis of integrated physical-chemical parameters, determined the influence of physico-chemical properties of slag content metal globules in it. Recommended to carry out the adjustment of the chemical composition of the slag additive lime bucket before desulfurization. Formulated scheme technological operations on rational technology training to iron smelting BOF. Developed understanding of the behavior of sulfur in hot metal desulphurization with magnesium. At the level of interatomic interaction studied the effect of chemical composition on the technological properties of molten slag. Revealed that the most significant impact on the content of the metal globules in slag has a surface tension of slag. Informed decision physico-chemical parameters as criteria for assessing the technological properties of molten slag. Implemented . Metallurgy.
