BLAST FURNACE STATUS CONDITION DETERMINATION DEVICE, OPERATING METHOD OF BLAST FURNACE, AND BLAST FURNACE STATUS CONDITION DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a blast furnace status condition determination device, an operating method of a blast furnace, and a blast furnace condition determination method capable of appropriately determining raw material loading and reaction bias and disturbance in the circumferential direction of the blast furnace.;SOLUTION: The blast furnace status condition determination device comprises: temperature distribution measurement means for measuring a temperature distribution right above a raw material loading surface in a blast furnace; main component analysis means for performing main component analysis based on the information on the temperature distribution measured by the temperature distribution measurement means; and determination means for determining whether the temperature distribution is normal on the basis of a main component analysis value obtained through the main component analysis by the main component analysis means.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
