    Abstract:

    Physico-chemical properties of the oxide system ÑaI-SiO2-MgO-Al2O3-B2O3 (slag viscosity, its refining properties and interfacial distribution of boron) were researched. Rational composition of boron-containing slag and method of slag formation in the ladle-furnace using lime, aluminum and colemanite, containing B2O3 up to 40%, were developed. Processing a low carbon steel by slags provided content of boron in the steel 0,001-0,012%, sulfur concentration in the metal not more than 0,005-0,010%, decreased consumption of manganese ferro-alloys from 0.2 to 1.3 kg/ton, improved strength properties of rolled metal maintaining high plastic characteristics.
