The sintering of iron ore fines is a century old technology. There has been gradual improvement in sintering process, sinter plant engineering, process control & automation and several others. Improvement in sintering technology and close control on sinter quality has enabled sinter to be the most favoured burden material in the blast furnace around the world. Blast furnace burden constituting high proportion of superior quality sinter enables low cost operation.
In the recent past, several important developments have been made in plant design features, sintering technology, which have substantially increased sinter machine size and improved plant efficiency, viz. productivity, product quality and its consistency, reduced energy consumption, lower cost and reduced emissions.
This paper discusses the major technical considerations of iron ore sintering for improved sinter plant performance. Technology status of the new plants vis-a-vis that of the old units and suitable measures envisaged for upgradation of some old units in India for improved persormance as well as the operating practive and the major impediments experienced in Indian sinter plants with remedial measures have also been discussed.
