Abstract

The paper examines the possibilities of modern electroslag remelting technology and modern electroslag furnaces for recycling alloyed steel grades. The expediency of the EES according to the two-circuit scheme of electrodes with non-constant length geometric parameters and non-compact metal charge materials is shown. It has been experimentally proven that the two-circuit EPC allows for efficient recycling of spent small-sized tools, both assembled into consumable electrodes and in the form of a non-compact charge, while preserving the chemical composition of the metal and obtaining ingots with a high-quality surface.
