Abstract

O uso de finos de minério de cromo na forma de aglomerados auto-redutores tem se mostrado eficiente, uma vez que aumenta a velocidade de redução e diminui as demandas energéticas, reduzindo os custos finais do processo. Neste trabalho estudou-se o comportamento de redução de pelotas compostas de minério de cromo, cimento, CMC, coque de petróleo e Fe-Si. Utilizou-se minério de cromo em duas diferentes granulometrias: -400# (d<38μm) e -50#+65# (210μm

Efficient process has been developed for production of ferrochromium (FeCr) by the use of chromium ore fines in self-reducing agglomerates. It increases reaction rates and decreases the energy consumption, therefore reducing its final production cost. The reduction process of pellets composed of chromium ore, cement, CMC, petroleum coke and Fe-Si was studied. Two different particles size of chromite were used: -400# (d<38μm) and -50#+65# (210μm
