ON OPTIMIZATION OF STEELMAKING IN ELECTRIC ARC FURNACE AND ITS LADLE TREATMENT IN LADLE-FURNACE
Steelmaking in arc 150-ton electric furnace using iron-rich pellets is considered. It is shown that the melting results are determined by the conditions of the simultaneous processes of the pellet melting and the melt oxidation refining. At that, it is important to monitor both the level of the bath...

Steelmaking in arc 150-ton electric furnace using iron-rich pellets is considered. It is shown that the melting results are determined by the conditions of the simultaneous processes of the pellet melting and the melt oxidation refining. At that, it is important to monitor both the level of the bath thermal supply baths, and the decarburation and steel reheating processes. The technique of the synchronous control over the heating modes, and the bath decarburation with varying in the course of melting metal weight, is developed on the basis of the data acquired under the operating conditions. It is found that the basic energotechnological process indicators (including those taking place in the complex steel processing facilities) improve if the melting of the metallized raw materials is conducted in the field of the optimal steel superheated area above the liquidus line with full immersion of the electric arcs in foamed slag. The proposed flowchart and algorithm of parameter determination for the heat-and-power mode under the ladle treatment in the ladle-furnace ensure the saving energy costs by 39.5‒40.5 kWh per 1 ton of the steel made in the EAF. |
