The invention discloses a fence type combined electrode ore heat melting furnace and a control method thereof. The fence type combined electrode ore heat melting furnace structurally comprises an electrode system and a furnace body. The electrode system comprises an upper electrode holder, a lower electrode holder, an electrode copper tile, a middle shaft negative electrode, a peripheral fence type negative electrode, a furnace bottom positive electrode, a power supply, a transformer, a motor crawler device, a general control computer and a voltmeter. The furnace body comprises a furnace cover, a furnace shell, a furnace lining, a furnace body support, a water pump and a thermocouple. The electrode system enables a current to flow through furnace charge near the furnace lining side throughthe peripheral fence type cathode electrode. Compared with a traditional single electrode ore heat melting furnace, the Joule heat extreme value in the fence type combined electrode ore heat meltingfurnace is reduced, the range of Joule heat distribution in the furnace is expanded, the problem of the uneven heat distribution of the furnace charge heat in the furnace can be effectively improved,at the same time, the utilization efficiency of energy in the furnace and the melting rate of the furnace charge are further improved, and the fence type combined electrode ore heat melting furnace and the control method thereof can be widely used in metallurgical and chemical industries.
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...
