A 16 MVA (14 MW) transferredarc furnace was commissioned at Palmiet Ferrochrome in Krugersdorp at the end of 1983, and was uprated to 40 MVA (32 MW) in 1988. Based on the successful operation of the DC arc furnace for chromite smelting, Middelburg Ferrochrome started up a 62 MVA (~40 MW) DC arc furnace, the largest of its type, in 1997.
· Ironmaking in Rotary Hearth Furnace. Ironmaking in the rotary hearth furnace (RHF) is a direct reduction process which utilizes noncoking coal for the reduction of iron ore. The RHF is the process reactor which consists of a flat, refractory hearth rotating inside a stationary, circular tunnel kiln. Inside the RHF, direct reduction of iron ore or ironbearing waste materials occurs, using ...
