Abstract:

A higher bed height - up to 680 mm, including a 30 mm hearth layer of sized return sinter - and high suction below the grate bars up to 1400 mm WG have resulted in increasing productivity to 33 t m^-2/day and have reduced the coke rate to a level of 46 kg t^-1 sinter. Ferro wastes such as blue dust, flue dust, mill scale, collection from dust catcher and gas cleaning plant, have been successfully added to the charge mix to produce quality sinters. In this paper, work carried out at the Regional Research Laboratory (CSIR) over the last few years is briefly descibed and two case studies are discussed, including the successful development of pan sintering units.
