Abstract—A comparison of two methods of electroslag remelting (ESR) of consumable electrodes is presented, with continuous and cyclic process management and changing consumable electrodes during melting. Technological and technical-economic aspects of choosing the type of ESR are considered. Analysis results and experimental study of the influence of a power input interruption, which occurs when changing an electrode during cyclic ESR, on the quality indicators of a melted ingot are presented. In contrast to cyclic ESR, continuous electroslag remelting of non-replaceable consumable electrodes is shown to ensure the fulfillment of strict requirements for the homogeneity of an ingot structure and the mechanical properties and characteristics of products.
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.
