Green fluxed pellets of ~18 mm diameter were made by mixing 30% lime and iron ore fines with the addition of the optimum water content. Use of lime was restricted to 30% as beyond this the green strength of pellets decreases adversely (pellets basicity ~3.6).5 Fluxed pellets were hardened at 1473 K (1200°C) to achieve sufficient strength. Hardened fluxed pellets were reduced in the …
