Description

technical field [0001] The invention relates to a decoupling-based neural network-based electrode lifting control method and system for submerged arc furnaces, which are suitable for the production process of submerged arc furnaces with various capacities and various smelting varieties that use three-phase electrode heating to realize smelting. Background technique [0002] The submerged arc furnace is a major equipment for smelting ferroalloys by the "electrothermal method". The electric power is introduced into the mixed raw materials in the furnace through three-phase electrodes, so that the furnace materials are heated and melted, and a redox reaction is generated to form ferroalloys. In order to ensure that the furnace materials in the three reaction crucible zones in the submerged arc furnace undergo chemical reactions simultaneously, to achieve high yield and low consumption, it is required to control the temperature distribution in the furnace evenly during the smelti...
