Abstract

A silicon-containing material based on non-market (unsized) fractions of the magnesium-containing modifiers for the production of high-strength cast iron and vermicular graphite cast iron (VGCI) is proposed for ironmaking as an alternative of the popular FeSi45 ferroalloy. The economical scheme of a reasonable alternative application and specific features of the chemical composition and interaction of the silicon-containing material with molten cast iron are presented. The efficiency of its use for ironmaking in electric-arc furnaces has been confirmed in practice.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
