Abstract
PURPOSE: To maintain the top pressure of a blast furnace always constantly by detecting the actual top pressure and the pressure in the front of the top pressure controlling device and applying cascade control to the actual top pressure and the pressure in the front of the controlling device.
CONSTITUTION: The actual pressure of blast furnace 3 is detected by top pressure detector 17 and detected signal 18 is entered in top pressure regulator 19; the set top pressure and the actual pressure are compared in top pressure regulator 19 and deviation signal 20 is entered in front pressure regulator 21. Since front pressure regulator 21 has entered actual front pressure signal 23 from front pressure detector 22 equipped between first dust collector 6 and septum valve 7 and in the front of the position branched to generating set 11, front pressure regulator 21 compares deviation signal 20, which has been cascade-entered, with actual front pressure signal 23 and outputs deviation signal 24 to the valve driving device of septum valve 7 to control opening/closing of septum valve 7.
