The adjustment methods of calcium carbide furnace conditions include voltage regulator switches, electrode lifts, and changes in charge resistivity. For slight load changes, electrode lifts are commonly used. In order to have a positive effect on the control, furnace conditions and energy loss of the calcium carbide furnace, this paper proposes a fuzzy control method for the electrode lift of calcium carbide furnace based on constant power. By detecting the electrode current and electrode voltage, the electrode position is obtained indirectly, and then the fuzzy control idea is used to determine the control amount of the electrode lifting, and the control volume is converted into a pulse signal to act on the hydraulic solenoid valve to control the electrode lifting, so as to achieve a constant power consumption of the calcium carbide furnace the goal of. Simulation and practical applications show that this method can effectively avoid arc extinguishing and short-circuit phenomena, and has a certain positive effect on the operation of calcium carbide furnace, improvement of furnace conditions, and energy saving and consumption reduction.
