Abstract:
     The power consumption of electric steel can be decreased sharply and the smelting period can be shortened significantly by means of coaldust-oxygen gun for intensifying electric furnace smelting. The coaldust-oxygen gun mounted on the furnace wall in the definite inclined angle and tangential angle has a igniter and swirl blades. The smelting process is characterized by using coaldust-oxygen gun and electric energy simultaneously or only by coaldust-oxygen gun to supply heat during initial smelting and intermediate smelting stage.
