Abstract
PURPOSE: To secure a definite wind amount of the blast to the blast furnace regardless of the fluctuation of the level of operation, etc., by detecting the pressure of hot blast to the blast furnace and controlling the amount of the blast by adding or subtracting the amount of deviation from the standard pressure of hot blast for the estimated wind amount of charging pressure.
CONSTITUTION: The pressure of hot blast in the hot blast pipe 11 from the hot stoves 41, 42 and 43 to the blast furnace 5 is detected with the detector and transmitter 12 for the pressure of hot blast and is taken into the regulator 13 for the pressure of hot blast. The output of the regulator 13 for the pressure of hot blast is reset at the start of pressure charging and this reset output signal is addd or subtracted to the pattern signal of the blast from the program setter 9 with the addition and subtraction circuit 14 and, further, is added to the standard wind amount from the setter 8 for the flow rate of the blast at the addition circuit 15. By sending this signal to the controller 16 for the flow rate of the blast, the flow rate of the blast at the blower 1 is controlled. Besides, by equipping the restricting device 17 for the upper and lower limits following the controller for the flow rate of hot blast, the abnormal signal is cut off.
