Emerging Technologies for Ironmaking - An Indian Perspective

The chief source of metallic iron for steelmaking in India, even today, as it is in most part of the world, is through blast furnace (BF) route. This will continue to be so in the foreseeable future as the technology is most efficient, both process and economy-wise. However, as the world is moving into the next millennium, a critical look is being given to the process primarily because of its non-ecofriendliness (as a result of extensive use of metallurgical coal/coke requiring elaborate pollution control facilities) and huge investment involved for supporting facilities like extensive raw material preparation and handling, agglomeration, adoption of sophisticated instrumentation and control system, etc.
