Title:
高炉炉況状態判定装置、高炉の操業方法、及び、高炉炉況状態判定方法
Document Type and Number:
Japanese Patent JP6870694
Kind Code:
B2
Abstract:
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 measuring means for measuring temperature distribution right above a raw material insertion surface in the blast furnace; high temperature portion area calculating means for calculating a high temperature portion area having a temperature more than a predetermined temperature or the surface ratio of the high temperature portion area to the entire area in the radial direction of a furnace top part on the basis of information on the temperature distribution measured by the temperature distribution measuring means; and determining means for determining whether the conditions of the furnace are abnormal on the basis of the area or area ratio of the high temperature portion calculated by the high temperature area calculating means.SELECTED DRAWING: Figure 1
