IMPROVING THE QUALITY OF STEEL USED FOR THE MANUFACTURE OF CAST PARTS OF ROLLING STOCK THROUGH THE USE OF MODIFIERS

Abstract

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.
