Blast furnace is like to continue as the most efficient route to produce pig iron for its high productivity and cost optimization, for many years to come. Although a small part of iron making has been supplemented by alternate iron-making process such as direct reduced iron (DRI) and smelting reduction, however, the replacement of blast furnace for steel making is a distant dream. Thus, the refractory for modern blast furnace including cast house refractories is a critical issue and discussed in Chap. 3. Different refractory maintenances practices prolong campaign of blast furnace life with improved productivity, and thus their key features are enrolled. Starting from the reduction of coke rate to effective hot metal through runner is a challenging task to the operator in the mind of production cost reduction and in turn, efficiency of blast furnace is analysed.
