optimization of refractory lining used in blast furnace
Blast furnace relining has commencedArcelorMittal in
In a blast furnace iron ore (in the shape of sinter) and coke are converted into liquid hot metal at a high temperature. We have 2 blast furnaces referred to as blast furnace A and blast furnace B which serve as the heart of our production site. Blast furnaces operate for 20 to 25 years after which the refractory lining has to be renewed
