State of the Art of Mini BF in the World
摘要
The Chapter gives the characteristics of small blast furnaces and the comparison of large and small blast furnaces, estimates the number of furnaces in the world that can be classified as small, and the distribution by the main operating countries. A brief overview of the development of small furnaces in Europe, Brazil, Russia and countries of the former Soviet Union, China, India and ASEAN is given, taking into account regional characteristics, including the main process fuel, charge materials, the target product as well as the challenges facing blast furnaces and shaft recycling units. A preliminary conclusion has been made on the prospects for using mini blast furnaces in different regions. A case study of a mini blast furnace operating on 100% briquette charge is described.
