    Abstract:

    The presented work solves the problem of increasing steel quality with minimal cost by microalloying steel with boron during the formation of oxide system ÑaI-SiO2-MgO-Al2O3-B2O3 in ladle furnace with use of the colemanite. Colemanite - boron-containing material containing B2O3 up to 40%, which is produced in Turkey.
    Physico-chemical properties of the oxide system ÑaI-SiO2-MgO-Al2O3-B2O3 (slag viscosity and interfacial distribution of boron) were researched. The rational composition of boron-containing slag and method of slag formation in the ladle furnace using lime, aluminum and colemanite were developed. Processing a low carbon steel by slags provided content of boron in the steel 0,001-0,012%, a decrease in the concentration of sulfur 0,005-0,015%, a decrease in the concentration of manganese in the metal on 0,02-0,04%, decreased consumption of manganese ferro-alloys from 0.3 to 0.6 kg/ton. New data on the morphology of nonmetallic inclusions, on the structure and on properties of the steel are obtained. Increasing the strength properties of steel and preserving the plastic characteristics are observed.
