B. Technology Absorption
Research & Development (R&D)
1. Specific areas in which R&D was carried out by the Company:
(a) Use of Anthracite coal to reduce nut coke consumption in Ferro Chrome Plant.
(b) The Pig Iron yield has been improved due to modification of moulds and installation of movable trolley.
This has also reduced jamming of Pig Casting Machine.
(c) Controlled cooling of Coke resulting in less moisture in the coke.
(d) Controlled cooling of ferro chrome hot cake to save water and reduce water accumulation in hot zone.
(e) Coke pusher car track is being repaired to improve efficiency & consistency.
(f) Use of Iron ore fines of Blast Furnace in Sponge Iron Plant.
(g) Installation of VVVF drive in Lobe Compressor of DRI Kiln.
(h) Installation of Weigh Feeders & Belt weighers in DRI Unit.
2. Benefits derived as a result of the above R&D:
(a) Increase in the sales realisation of Hot Metal.
(b) The pig iron yield has improved which has higher value compared to scrap.
(c) Higher the moisture in the coke, higher will be the coke rate in the Blast Furnace. The reduced coke rate is
due to less moisture in the coke.
