| Mainly composed of silicon manganese furnace heat furnace, ring feeding system, electric system, single-phase transformer, electrode lifting winch control subsystem, cooling water system, etc., is the production of manganese alloy main equipment, the three-phase electrode is inserted through the charge for buried arc operation, the use of the energy of the arc and the current through the charge, due to the resistance of the charge generating energy, the raw material at a certain temperature, chemical reduction reaction manganese alloys. Manganese-phase electrode lifting system control performance directly affects the furnace temperature; determine the manganese alloy smelting efficiency and quality. For our company behind silico-manganese furnace manual control electrode lifting system has been modified to increase the position detection electrodes constructed three-phase electrode lifting the automatic control system hardware and software platforms, and the electrode lifting actuator has been transformed for the realization of silicon manganese alloy production process automation, improve production efficiency and product quality, reduce energy consumption targets. For manganese furnace, analyzes the current existence of various electrode control strategy, according to the actual situation of the company, the choice of the PID algorithm as the three-phase electrode lifting control system control strategy. Finally, the effects of the transformation were evaluated. |
