Í kjölfar endurskoðunarinnar, til að hvetja til lágkolefnistækni fyrir framleiðslu á vörum úr köggluðu járngrýti sem mötunarefni fyrir fyrstu framleiðslu á stáli og til að huga að þörfum grænnar stáltækni, þykir rétt að opna viðmiðunina fyrir glætt málmgrýti fyrir staðgönguvörum.
- [en] Following the review, to incentivise low-carbon technologies for the production of agglomerated iron ore products as feed into primary steel production and to consider the needs of green steel technologies, it is appropriate to open the sintered ore benchmark to alternative products.
- Skilgreining
- [en] Agglomeration of Iron Ore: Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the fee. So, they are agglomerated (by igniting at lower temperature causing only interfacial fusion) into larger lumpy pieces with/without addition of additives like limestone, dolomite etc.
Two types of agglomerated products are commonly produced/ used in the industry namely Sinter and Pellet. Accordingly the processes are known as Sintering and Pelletising respectively :
(a) SINTER : Sinter is a clinker like aggregate which is normally produced from relatively coarser fine iron ore (normally -3mm) mixed with coke breeze (-3mm), limestone dolomite fines (-3mm) and other metallurgical return wastes from the plant.
Sinter is a much preferred input/raw material in blast furnaces. It improves BF operation and productivity and reduces coke consumption in blast furnace. Presently, more than 70% hot metal in the world (in India 50%) is produced through the sinter.
(b) PELLET: Pellets are normally produced in the form of Globules from very fine iron ore (normally -100 mesh) and mostly used for production of Sponge Iron in gas based plants, though they are also used in blast furnaces in some countries in place of sized iron ore.
