  • Control method of and apparatus for material charging at a top of a blast furnace
    Patent number: 5196050
    Abstract: In a control method of material dumping at top of a blast furnace, in which material stored in a furnace top bunker is dumped through a flow rate control gate into a blast furnace in a specified time, value of initial material weight before the transfer start, divided by the specified time is set to first target dumping speed, and opening of the flow rate control gate is feedback controlled based on the measured material weight during dumping, so that the actual dumping speed after the dumping start is coincident with the first target dumping speed, and further, if necessary, remaining material weight in the furnace top bunker on the way of dumping is actually measured and value of the remaining material weight divided by the remaining time is set to second target dumping speed, and opening of the flow rate control gate is feedback controlled, based on the measured material weight during dumping, so that the second dumping speed after the measurement of the remaining material weight is coincident with the sec
