Abstract:The rapid increase in world steel output during the last three decades has been accompanied by a growing geographical distribution of production, especially among developing countries. There have been tendencies towards both larger and more efficient units for achieving high production and less environmental impact. Currently, about 40% of steel is manufactured from recycled scrap, which uses only 15-20% of the energy needed to make steel from virgin ore. The cut throat competition from the electric furnaces and environmental norms is getting more stringent. The very sustenance of Blast Furnace is chiefly dependent on the level of optimized usage of available raw material. Apart from the regular raw materials, like coke, coal, iron bearing materials and fluxes, the blast furnaces also consume many utilities such as nitrogen, steam, water and consumables for safe and efficient operation. This paper elaborates the actions taken to reduce the raw materials, utilities and consumables, thereby saving over USD 30 M. References:1. Elsayed A.
