Abstract
The paper describes the results of pilot remelting of high-carbon ferrochrome dust in a 1.8 MVA DC arc furnace. Standard grades of high-carbon ferrochrome, such as FeCh800, FeCh850 and FeCh900, were obtained with the following furnace performance: chrome extraction - 89,5 %; slag ratio - 0,5; specific power consumption - 2 272 kW·h/ton.
