The present paper reports the performance analysis of the blast furnace 'X' of Bhilai Steel Plant (BSP). Special reference has been madeto the process variables related to the burden, such as sinter. The analysis shows that the burden rate has beenthe most significant variable for the coke rate followed by the temperature of hot blast. A change in burden rate has been mainly reflected by a change in the weight ot raw limestone in the burden. Considerable saving in coke rate is achieved by

The productivity is adversely affected by the content of undersize fraction in lump ore as well as in sinter. On the basis of empirical equations, reported in the present work, salient approach for the improvement in the performance indices of the blast furnace has been mentioned in the text, Improvement in the quality of sinter as well the granulometry of lump ore is important in this regard. The methodologyto achieve such improvement has been outlined in the present paper.
