Monitoring Blast Furnace Lining Condition During Five Years of Operation

Abstract

Changes in lining temperature for the shoulders, bosh, and shaft, their mean-square deviation with respect to furnace surroundings, and also overall thermal loads of the cooling system for blast furnace No. 3 at the Enakievo Metallurgical Plant are analyzed for five years of operation: from December 2011 to September 2016. Limiting values of temperature are established that point to partial or complete shaft lining wear. Features are revealed for the effect of blast-furnace smelting production conditions on the change in blast-furnace lining temperature. The furnace well condition is evaluated.
