Smelting of carbon alloy from iron ore of the Mene-Aldan ore occurrence in the Republic of Sakha (Yakutia)

Abstract

The article presents the results of studies into the physical and mechanical properties of a material obtained by metallurgical smelting according to a technological scheme for creating alloys based on mineral raw materials of Yakutia. It was found that, in terms of its physical and mechanical properties, the alloy belongs to the class of cast tool steels according to GOST 1435-99. The fine-grained homogeneous structure of the alloy indicates its improved physical and mechanical properties. The ultimate tensile strength and hardness of the material correspond to the values of high-quality carbon steels after normalization. The feasibility of using iron ores of sedimentary origin from the Mene-Aldan ore occurrence in the development of tool cast steels and alloys has been confirmed.
