Abstract
The Indian steel industry is likely to witness tumultuous activity in the expansion of existing plants as well as in the installation of new green field projects in different part of the country. These projects comprise conventional, non-conventional and alternative ironmaking processes. While blast furnace iron making is central to the production of steel, the secondary steel sector has uniquely included electric induction furnace steel making in addition to the electric arc furnace units. Both these units depend mainly on scrap or direct reduced iron for metallic input. It entailed large numbers of coal/gas based direct reduced iron units, mini blast furnaces and COREX plants for hot metal (pig iron). Several direct reduction-smelting reduction eco-friendly technologies to directly use iron ore fines, and non-coking coal as reducing agent and energy source are under development. India has adequate raw material resources for the production of iron and steel and a comfortable market opportunity and an inherent urge to ‘achieve’ and add values to indigenous raw materials through research and innovation. The paper highlights the research and development efforts undertaken in the area of iron making specifically with respect to reducing energy consumption and CO2 emissions. The paper further focuses on some research areas likely to be undertaken for developing and or adopting new apt iron making processes/ technology under Indian conditions to sustain in the competitive steel growth and global economy.
