New possibilities of Consteel furnaces
Abstract
The disadvantages of Consteel electric furnaces, which are mainly caused by the low efficiency of heating of a charged metal scrap by effluent furnace gases, are considered. A new concept of an electric-arc furnace with scrap heating on a conveyer by powerful burners, which provide fast scrap heating to 800°C, is proposed. As follows from calculations, the capacity of such a furnace increases substantially, the specific electric power consumption decreases, and the emission of toxic substances into the atmosphere decreases as compared to the existing Consteel furnaces.
