<p>Method for melting ferrous metals, particularly scrap, by means of an electric arc melting furnace for the production of steel for significantly reducing the consumption of electric power supplied to the melting furnace for melting. In order to achieve this aim, the invention meets the heat demand of the melting process by introducing and burning complementary energy-releasing material that is intimately mixed with the ferrous material fed into the furnace. According to a preferred embodiment of the invention, the complementary energy-releasing material is introduced and burned during the conveyance of the ferrous material in a horizontal preheating channel of which the plant (for example a so-called CONSTEEL plant) is provided, but the invention is not limited to use in combination with such a plant but can also be applied to all other known plants for melting ferrous material (for example, conventional shaft furnaces with a vertical feeding channel). The attainable saving in electric power, for example by using tire rubber as added energy-releasing material, can be on the order of 20%, calculated on the total necessary melting energy. <IMAGE></p> |
