<p><P>PROBLEM TO BE SOLVED: To provide a method for charging a raw material for blast furnace, which can charge a raw material for blast furnace at an uniformed distribution into a bell-less blast furnace having a plurality of furnace top bunkers, and to provide a facility for charging a raw material for blast furnace. <P>SOLUTION: In the facility for charging a raw material for blast furnace, the raw material for blast furnace is conveyed to a furnace top of the bell-less blast furnace 1 by a furnace top conveyor 3 and fed into the furnace top bunkers 21-23 from a furnace top hopper 4; the fed raw material for blast furnace is discharged into a receiver 10 from raw material discharging valves 91-93; and the discharged raw material for blast furnace is charged inside the furnace top of the bell-less blast furnace from a rotating chute 11. The facility for charging a raw material for blast furnace includes: a calculation device 14 for calculating a weight of the raw material for blast furnace inside the bunker by correcting bunker weight measurement values measured by load cells 121-123 with a preset correction coefficient; and a control device 15 for controlling the raw material discharging valves to be opened or closed based on the calculation result outputted by the calculation device 14. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
