Electric furnace steelmaking is in ascendance in iron and steel production enterprises. At present, electric furnace steel occupies a considerable proportion of the three methods of open furnace, converter, and electric furnace steelmaking. Graphite electrode is conductive material in electric arc furnace steelmaking. The consumption of graphite electrodes in electric arc furnace steelmaking depends not only on the quality of the electrode but also on the level of steelmaking operation and management.
The main factors affecting graphite electrode consumption in electric arc furnace steelmaking are as follows:
(1) Loading quantity and feeding method.
(2) feeding time and power off time.
(3) smelting cycle.
(4) the amount of exhaust gas emission and the quality of the dust removal system.
(5) electrode adjustment quality.
(6) load regulation quality.
(7) oxygen-blowing operation.
(8) Quality of electrode connection.
(9) Quality of electrode joint body.
(10) Machining precision of electrode joint hole and joint.
