METHOD FOR CORRECTING INFLUENCE COEFFICIENT APPLIED INTO MEASURED WEIGHT CORRECTION IN PARALLEL BUNKERS FOR BELL-LESS BLAST FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a method for correcting an influence coefficient among bunkers in the measurement of weight in the bunker in a bell-less blast furnace having parallel bunkers as a furnace top charging facility.;SOLUTION: Before and after receiving the raw material into the bunker or before and after pressure-exhausting/pressure-equalizing in the bunker, the weight and the pressure in each bunker, are measured and the respective rates of changes in the weight values and the pressure values in each bunker before and after receiving the raw material into the bunker or before and after pressure-exhausting/pressure-equalizing in the bunker, are calculated from the measured each weight value and pressure value. The influence coefficient for corrective calculation of the weight among the bunkers, is calculated from these rates of changes obtained by calculating and this influence coefficient is used to the influence coefficient used ever.;COPYRIGHT: (C)2002,JPO
