DEVICE FOR DETERMINING CONDITION OF BLAST FURNACE, METHOD FOR OPERATING BLAST FURNACE AND METHOD FOR DETERMINING CONDITION OF BLAST FURNACE

摘要

To provide: a device for determining conditions of a blast furnace, capable of appropriately determining deviation and disorder in raw material insertion and reaction in the circumferential direction of the blast furnace; a method for operating the blast furnace; and a method for determining the conditions of the blast furnace.SOLUTION: The device for determining conditions of a blast furnace comprises: temperature distribution measurement means for measuring temperature distribution right above a raw material insertion surface in the blast furnace; high temperature portion position detecting means for detecting a position of a high temperature portion having a temperature more than a predetermined temperature on the basis of information on the temperature distribution measured by the temperature distribution measurement means; and determining means for determining whether the conditions of the furnace are abnormal on the basis of the position of the high temperature portion detected by the high temperature portion position detecting means.SELECTED DRAWING: Figure 1
