Technical Field

[0001] The invention belongs to the technical field of direct current furnaces, and in particular relates to a process for optimizing the operating energy consumption of direct current furnaces. Background Art

[0002] A DC arc furnace refers to an arc furnace that uses direct current as energy. Like an AC arc furnace, it uses the arc generated between the electrode and the charge (or molten pool) to generate heat, thereby achieving the purpose of smelting. It can be used to smelt steel, alloys, and non-ferrous metals. Publication number: CN201779998U, discloses a metallurgical DC electric furnace device. The present invention relates to a metallurgical smelting device, in particular a device for smelting and producing nickel iron in a DC electric furnace. The electrodes arranged at the bottom of the DC electric furnace adopt a series of cooled integral conductive blades, and are installed under the magnesia carbon bricks, and a cooling air inlet and a cooling air outlet are provided at the spatial position where the electrodes are installed at the bottom of the furnace. The energy consumption of the present invention is low, which is 5-10% lower than that of an AC electric furnace. It is simple to operate, has low noise pollution, strong molten pool stirring, and little impact on the previous power grid.

[0003] The problem with the above technology is that after smelting is completed, most existing electric furnaces have to wait for the electric furnace to cool down before they can proceed to the next smelting step. However, the cooling time is too long for the next smelting step to proceed quickly, resulting in low work efficiency. At the same time, when cooling the electric furnace, the cooling device is large and integrated, and the staff needs to move the cooling device to cool the electric furnace, which makes it impossible to quickly cool the electric furnace with the cooling device. Therefore, we propose a process and device for optimizing the operating energy consumption of the DC electric furnace. Summary of the Invention
