Ferrochrome smelting is an energy intensive process, with the typical electrical consumption ranging between 2000 and 4000 kWh/t FeCr, depending on pre-reduction and pre- heating of the charge material3. Figure 1 illustrates the reduction in power consumption when using agglomerated fines and sintered pellets.

Ferrochrome Process. Outotec SAF smelting technology is suitable for various ferroalloy applications: FeCr,heater and a fan. The electrode equipment has its own hydraulic and,off-gas, as well as effectively pressurizes the scrubber

4 SMELTING Smelting tests were conducted at 1750ºC in an argon atmosphere. The pulverised smelting charges made use of silica as a flux and a petroleum coke as a reductant (Table 4:), and were combined in the ratios given in Table 5:. The smelting charges were contained in graphite crucibles and allowed to react for 30 min at temperature.

07-01-2022· Ferrochrome production creates air pollution, dust, slag waste produced during ferrochrome separation from other ore elements and process water These waste materials have the potential to be contaminated with chromium and other heavy metals and chemicals of

the CO-rich off-gas from a set of 4 closed furnaces. Semi-open and closed furnaces have different requirements for test work and modeling to evaluate waste energy, since gas compositions and temperatures are dissimilar. Common activities for evaluation are the following: • Furnace predictive process modeling and off-gas optimization.
