FIELD: metallurgy.
SUBSTANCE: charge material for electric arc furnaces consists of disperse iron-containing wastes of metallurgy and engineering and a carbonaceous binder that does not contain sulfur. The said waste contains oxidized and/or reduced iron with a ratio between them in the range of 1:0 to 0:1, and the ratio between mentioned waste and the binder is 0.7:0.3 to 0.2:0.8.
EFFECT: invention provides for the recycling of disperse wastes of metallurgy and engineering, which include metal iron, carburization of a metal bath of an electric arc furnace and energy savings.
