S. A. Tyutyukov, doktor tehnicheskih nauk, dotsent, direktor NOCHU «Institut dopolnitelnogo professionalnogo obrazovaniya rabotnikov zdravoohraneniya», A. V. Andreev, nachalnik proizvodstvenno-tehnicheskogo kompleksa OAO «Uraltransmash»The economical and technological aspects of use of perspective materials (iron of direct reduction) are discussed in this article. The expenditure of iron-manganese (88 %) alloy was 1,8 time less. The expenditure of iron-silicon (45 %) alloy was 2,35 time less. The expenditure of electric energy was less on 5 %. Mechanical properties of steels from experimental smeltings corresponded to requirements of the GOST 22703-2012.
