Abstract
PURPOSE: To stabilize operating voltage by detecting the opening condition of the cover of an electric furnace and controlling the voltage to be applied to discharge electrodes in an electric dust precipitator in an electric furnace for steel making.
CONSTITUTION: An electric power source device 8 receives controlling by the control signal from a furnace cover slewing control unit 2 by opening and closing of the cover 1 of an electric furnace 9. While the furnace cover is in a closed state for the beginning, the A showing the ON, OFF of electrode current supply indicates ON state and during this time, the operating voltage of an electric dust precipitator 4 is the same as the initial voltage as shown by D. Whereas, at the charging of raw materials, as shown in C, the cover 1 is opened like B, then the A indicating electrode current supply goes OFF, and during this time, the operating voltage of the precipitator 4 is controlled as shown by D. Hence, there is no unstability of the operating voltage of the electric dust precipitator along with the opening and closing of the furnace cover, and the dust collection efficiency is made always high.
