    Abstract:

    Cost-saving metallothermic method was proposed for ferro-silicoboron (FeSiB) production of borate raw and ferrosilicon. The results of the present research aimed to search the rational composition of new boron-containing ferroalloys containing 64-65% of silicon and 0.8 - 1.0% of boron and the development of the efficient production technology of the alloys is presented. The boron reduction of boron-containing raw by high-silicon ferrosilicon (45 - 75 % of Si) was studied in laboratory conditions. The investigation results testify that the proposed composition of the boron-containing ferroalloy and its production technology are rather efficient. The obtained FeSiB was tested in a steel making: smelting in electric furnace and out-of-furnace treatment. It was established that the existing technological scheme for metal deoxidization by ferrosilicon is preserved when FeSiB is applied. Furthermore, steel microalloying by boron can take place within the scheme, and the degree of boron digestion ranges up to 77.8-96.3%. It was noted the chemical composition of steel in respect of boron content was rather constant during the whole period of out-of-furnace treatment.
