The invention discloses a fence type combined electrode submerged thermal melting furnace and a control method thereof. The structure of the fence type combined electrode submerged thermal melting furnace includes an electrode system and a furnace body. The electrode system includes an upper electrode holder, a lower electrode holder, an electrode copper tile, a central axis cathode electrode, a peripheral fence type cathode electrode, a furnace bottom anode electrode, a power supply, a transformer, a motor crawler device, a total control computer, and a voltmeter. The furnace body includes a furnace cover, a furnace shell, a furnace lining, a furnace body support, a water pump, and a thermocouple. The electrode system includes arranging the peripheral fence-type negative electrode, so that the current can flow through the charge close to the lining side. Compared with the traditional single-electrode submerged thermal melting furnace, the fence-type combined electrode submerged thermal melting furnace not only reduces the extreme value of Joule heat in the furnace, but also expands the distribution range of Joule heat in the furnace, which effectively improves the uneven distribution of heat in the furnace. At the same time, it also improves the energy utilization efficiency in the furnace and the melting rate of the charge, and can be widely used in the metallurgical and chemical industry.
Description
technical field [0001] The invention belongs to the field of metallurgical and chemical production, and in particular relates to a fence-type combined electrode ore-thermal melting furnace and a control method thereof. Background technique [0002] As an important part of industrial production, submerged heat smelting furnace is widely used in steel and non-ferrous metal smelting processes. In recent years, with the development of society and the advancement of science and technology, the energy consumption, production capacity and emission requirements of submerged thermal smelting furnaces have become higher and higher. Can be applied on the furnace. In the existing technology, the electrodes of submerged thermal smelting furnaces are mostly cylindrical electrodes. When the electrodes are inserted into the charge for submerged arc operation, the energy of the arc at the end of the electrode and the resistance heat generated by the current flowing through the charge are us...
