Raipur, January 3
A strategic decision taken by the Bhilai Steel Plant (BSP), an entity of Steel Authority of India Limited (SAIL), to reduce sinter percentage in burden first in Blast Furnace (BF) 8 and then in BF 7 has yielded the desired results.
The Blast Furnaces have sustained daily Hot Metal production levels between 17500 and 18000 Tonnes even with daily sinter production of less than 24000 T owing to one sinter machine in Sinter Plant 2 under breakdown from 23rd Dec’22 onwards. Daily consumption of sinter in BF 7 and BF 8 has strategically been reduced by 3200 T.
From 15th Dec’22, a decision was taken by the plant to reduce sinter percentage in burden. In BF 8, sinter percentage in burden was kept at 52 to 55 per cent. The pellet percentage in burden is 22 per cent in BF 8. The same modality was followed in BF 7 also.
This decision has led to reduction in daily consumption of sinter in BF 7 and BF 8 by around 3200 T. This reduction in consumption has resulted in filling up of emergency sinter bunker of Sinter Plant 3 to a level of around 18000 Tonnes.
The shop has been able to sustain daily Hot Metal production at 17500 to 18000 T with no reduction in blast on account of sinter shortage. Earlier, there was blast reduction due to sinter shortage. Now with reduced sinter percentage, there is no sinter shortfall inspite of non-availability of one machine of Sinter Plant 2.
In Oct 22, sinter percentage in burden was 65.5 with average daily consumption of sinter at 8370 T. In Nov 22, the sinter percentage in burden was 60.5 with average daily consumption of sinter at 8465 T. With sinter percentage in burden reduced to 56.5 in Dec 22, average daily consumption of sinter is now down to 7056 Tonnes.
This game changer strategy taken by the Plant was implemented first by BF 8 Team under guidance of Shri Tapas Dasgupta, CGM In-charge (Iron). The same strategy is now being replicated in BF 7.
