摘要：
The use of hot-briquetted iron in large furnaces makes their operation more efficient. The time of furnace operation under current is shortened by 4 min, while unit electric-power consumption is cut by 15 kWh/ton for the melting of the charge and by 8 kWh/ton for the completion of the heat as a whole. These results are obtained when the amount of hot-briquetted iron in the cold charge corresponds to 0.3–0.4 of the weight of the scrap and the ratio of the mass of the cold charge to the mass of the metallized pellets in the charge is within the range 1.0–1.1.
