Abstract

The invention discloses a rotating electrode device for external electric field deoxidation of metal and slag. The device includes an anode electrode, a cathode electrode, a DC power supply and a metal wire. One end of the anode electrode is immersed in molten slag above a steel liquid to be deoxidized and filled in the furnace body; a stirring head and a rotating shaft of the anode electrode portion are integrally molded; the anode electrode can realize controllable spinning; the metal wire is connected with the rotary shaft part of the anode electrode through an electric brush; an electric spindle of a motor with adjustable speed coaxially drive the anode electrode; the electric spindle end of the motor with adjustable speed is fixedly connected with an end part of the anode electrode through an insulation material, so that the anode electrode can conduct axial rotation to further drive the stirring head part of the anode electrode to stir the molten slag; and the speed of the stirring head is adjusted according to the viscosity of the molten slag. The invention employs the electrodes to stir the steel liquid and molten slag, can increase the transfer rate of electrons as well as the transmission rate of the oxygen, thus greatly improving the deoxidation rate.

Description

technical field [0001] The invention relates to an electrode device, in particular to an electrochemical deoxidation electrode device, which is applied in technical fields such as metallurgical electrochemical refining and electrochemical alloying. Background technique [0002] Converter steelmaking is the main steelmaking method in my country, and a large amount of oxygen is often brought in during the smelting process. This makes deoxidation a particularly important link in the refining process of steel, and the oxygen content directly affects the quality of steel. However, the traditional deoxidation method is difficult to achieve high purity and the production efficiency is not high. The existing electrochemical non-polluting deoxidation method with an external electric field between slag and gold, its main principle is that between the molten metal and the slag, the top electrode inserted into the molten slag and the bottom electrode placed in the molten metal are appl...
