Reliable and stable operation with longer blast furnace campaign allows an increase in utilization of blast furnace for production of hot metal. Prolongation of the campaign requires monitoring refractory wear out and taking actions to retard lining deterioration. JSW and Hatch systematically monitor conditions of BF #3 lining using Acousto Ultrasonic-Echo (AU-E) methodology. Testing of blast furnaces revealed problematic areas, formation of elephant foot, extent of accretion, cracks and anomalies. Several measure were recommended and implemented to prolong furnace life while maintaining furnace productivity. The remaining furnace life was estimated and JSW started preparation for blast furnace reline.
