Abstract
Comparison of energy intensity and metal losses in electroslag technologies with consumable electrode remelting and use of liquid metal was performed, which showed the energy effectiveness and higher metal yield at application of the latter. At formation of an ingot from liquid metal with the effi ciency characteristic for the traditional ESR process, the power saving is equal to 57 %. The possibility of increasing the effi ciency by 15 %, by reducing metal overheating at electroslag remelting with liquid metal without a change of the process thermal conditions and ingot quality increases the power saving to 60 % of the losses in the traditional process. Metal losses are also by 14...60 % lower due to absence of consumable electrodes that gives a signifi cant cost effect. Ref. 23, Tabl. 1, Fig. 1.
Keywords: electroslag remelting; consumable electrode; electroslag technology with liquid metal; ESR ingots; electric power; metal; cost-effectiveness
