The growth of requirements for the properties of steel, as a rule, outstrips the development of technological techniques aimed at improving the purity of the metal. As a result, it is necessary to further search for effective ways of refining, alloying and modifying steel. In this regard, the development of new technological methods of smelting and out-of-furnace processing, allowing to effectively refine and modify steel, is an urgent task.This work is devoted to the development of new technological methods of smelting and out-of-furnace processing, in particular, improving the processes of refining and modifying steel in a steel ladle using PW.The initial metal was prepared in an induction crucible furnace with a capacity of 6 tons. After carrying out the desulfurization process in an induction crucible furnace, the reducing slag was partially removed and the metal was released into the bucket.
