Title: | Cold Bonded Carbon Composite Pellets for Utilization of Iron Ore Micro-Fines and Carbon Bearing Fines |
Area: | Chemical Sciences |
Focus Area: | Utilisation of Iron Ore |
Social Benefits: | This is a cold bonding process, so it is energy efficient. Curing time is very short (5-10 min), It utilizes iron ore micro-fines and coal fines or coke fines or carbon containing waste fines in iron making or sintering, The micro-pellets provide energy to the sinter bed for reduction in coke breeze consumption. 38-48 % reduction in coke breeze has been found when 38 % blast furnace flue dust containing pellets were mixed with iron ore in sintering (12 kg scale), Since it is a composite pellet, it can be reduced faster than normal pellets C02 in steel plant''s waste gas is utilized in strengthening of pellet. |
