Method for determining an operating parameter and / or a material parameter in an electric arc furnace, and electric arc furnace

摘要

Method for determining an operating parameter and / or a material parameter in an electric arc furnace (1), in which a molten material (3) that is in a lower container (2), especially steel, is heated with at least one electric arc (4), and at least one electric arc (4) burns between at least one electrode (5) and the molten material (3), and by at least one optical detection device (6, 7) it detects the light of at least one electric arc (4) and / or the light of the molten material (3), and the light is transmitted by an optical system, especially by means of at least one light wave (8, 9), at less a spectrometer (10, 11) and in it it is detected and / or analyzed to determine the operating and / or material parameter, it is characterized by the use of two optical detection devices (6, 7), which transmit light captured through a light waveguide (8, 9) to two spectrometers (10, 11), and an optical detection device (6) detects the light of the electric arc (4) and the other optical detection device (7) detects the light of the molten material (3), and both optical detection devices (6, 7) are located in a housing (12), which it is arranged in a wall area (14) of the lower container (2) and is directed towards the inside of the electric arc furnace (1), and both spectrometers (10, 11) are located in a reception space (15), which is arranged next to, or in the wall area (14) of the lower container (2).
