Automatic detection device for the position of the column of the conductive arm of the industrial electric arc furnace electrode

Abstract

The invention relates to an automatic detection device for the position of a column of an electrode conductive arm of an industrial electric arc furnace. The traditional electric arc furnace uses a linear displacement sensor and a metal pull wire structure to detect the position of the electrode conductive arm column, and the position data error is relatively large. The present invention is provided with a fixed central shaft seat fixed under the platform of the column guide wheel, and the lower part forms a rotational connection with the movable balance seat through the movable shaft, and the counterweight is fixed on the movable balance seat; the bracket protruding downward is fixed on the movable balance seat, connected There is a rotary encoder fixing seat and the rotary encoder is fixed; the rotary encoder is connected with the measuring guide wheel through a set pin, and is closely attached to the surface of the column guide rail; the dust-proof scraper perpendicular to the column guide rail is fixed on the bracket, and the end is tight. Attached to the surface of the column guide rail. The invention can accurately detect the value of the column position of the electrode conductive arm, grasp the electrical characteristics of the electrode operation inside the electric arc furnace, reduce the fluctuation of the arc current, improve the operation rate of the electric arc furnace production, and provide a reliable basis and means.

[0003] During the production of industrial electric arc furnaces, linear displacement sensors and metal pull wire structures are used to detect the position of the electrode conductive arm column. In different production stages, with the continuous vibration of the electrode conductive arm column, the tension of the metal pull wire changes continuously. The repeatability of the linear displacement sensor is poor, resulting in a large data error in the position of the electrode conductive arm column, which cannot accurately reflect the position of the conductive arm
