ferrochromium – Pretreatment for smeltinG

2012-2-7  reduction. Attempts to apply the RHF process to chrome ore pre-reduction carried out in the early late 1980’s and 1990’s were only partly successful, the main problem being the re-oxidation of the pre-reduced chrome pellets. However Industry in South Africa has favoured the rotary kiln approach to

The transformation of ferrochromium smelting

2009-8-26  Rotary kiln preheating In principle, the rotary kiln can be effectively used for preheating the charge and thus making use of the furnace gas. Outokumpu used a rotary kiln for preheating the pellet charge from 800 to 1000°C before continuous feeding to a closed furnace. The process operated satisfactorily. The main problem was the availability ...
