The results of the possibility for using of spent ANF-6-1 fl ux for electroslag remelting and breakage of spent
silicon carbide abrasive wheels in the smelting of 20GFL steel are presented. Noticeable advantage of the
experimental smelting technology is shown. Saving of expensive materials, reduction of harmful impurities in the
metal and increase in the desulfurization rate from 0.0004 to 0.0007 %/min are noted. The use of spent ANF6-1 fl ux for electroslag remelting made it possible to reduce the duration of melting, the consumption of slagforming materials and reducing agents. There is also decrease in electricity consumption by 11 kW/h per ton of
liquid steel. Increase in the plastic characteristics and impact toughness of 20GFL steel is shown when using the
experimental melting technology in comparison with the current one. At the same time, the strength characteristics
of steel remained at the same level. The economic effect at using of secondary materials in the smelting of 20GFL
cold-resistant steel is 430...450 rubles per ton of liquid steel.
