Abstract

The invention relates to the technical field of electric furnace metallurgy, and specifically discloses a brown corundum self-baking electrode for smelting brown corundum in a dumping furnace. It is fixed in the fixed sleeve, so that the copper tile in the fixed sleeve hugs the electrode cylinder tightly, and the electrode cylinder is fixed on the load-bearing steel platform through the holding system; the electrode paste feeding mechanism is used to add electrode paste to the electrode cylinder for roasting, and the height of the electrode paste column Controlled at 300-500mm; when the electrode paste in the electrode cylinder is roasted, cooling water is passed into the fixed sleeve to form a diameter of 690-710mm and a bulk density of 1.3-1.5g / cm 3 self-baking electrodes. The self-baking electrode that does not suspend or lose lumps is prepared by adopting the technical scheme in the present invention, which is suitable for smelting brown corundum and is worthy of vigorous promotion.

Description

technical field [0001] The invention relates to the technical field of electric furnace metallurgy, in particular to a brown corundum self-baking electrode for smelting brown corundum in a dumping furnace and a production process thereof. Background technique [0002] During electric furnace smelting, the current output from the transformer passes through conductive systems such as short nets and copper tiles, and finally enters the molten pool in the furnace through electrodes, generating arc heat and resistance heat, and then smelting metals. The electrodes are divided into carbon electrodes, graphite electrodes and self-baking electrodes. Among them, the price of self-baking electrodes is low, and the use of self-baking electrodes on smelting electric furnaces can greatly reduce production costs, so they are widely used. [0003] The production process of the existing self-baking electrode is usually: adding the electrode paste to the electrode cylinder, so that the elec...
