Abstract—A mathematical model is proposed to estimate the effect of rotation of a consumable electrode on the hydrodynamics of a slag bath during electroslag remelting. The critical speed of electrode rotation is determined as a function of the electrode diameter for the transition of a laminar to turbulent flow for an ANF-6 flux. The dependence of the flux velocity in the slag bath on the speed of electrode rotation is determined. An expression is proposed to estimate the time of renewal of the slag bath. The ratio of centrifugal to electromagnetic force is estimated; it determines the liquid-slag flow pattern and the conditions under which the hydrodynamics of the slag bath is controlled by centrifugal forces.
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.
