In Situ Temperature Measurement Across the Sinter Bed
Sinter making is an agglomeration process of iron ore fines. As sizes of iron ore fines are very small, iron ores are converted into sinter before charging to Blast furnace. Quality of the sinter depends on different parameters namely raw material, gas flow, heat pattern in sinter bed and granulation of sintering.
