Ferrochrome Wikipedia

Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.

PRELIMINARY CHARACTERIZATION OF THE SAMPLES TAKEN

2.2 Drill Sampling of the Ferrochrome Furnace Electric furnace drillings were performed at Outokumpu Tornio Ferrochrome Works. Samples were drilled from electric furnace no. 2 with a transformer power of 75 MVA. A separate access door (H=500mm, L=400 mm) was made in the gas space of an electric furnace shell. The

Homemade electric melting furnace

Electrical furnaces are there in different types Electric arc furnaces. A low voltage (preferably DC) and high current flows across (usually carbon) electrodes and reaches a temperature of over 3000 o C and melts virtually everything. But the temperature is hard to control and overheating is easily done, particularly with small quantities.

An Improved DC-Arc Process for Chromite Smelting

electrical energy usage higher than for a submerged arc operation smelting sintered pellets and preheated raw materials [1]. This shortcoming of the DC arc furnace may, however, be overcome by preheating the feed to the furnace in a fluidized bed or flash reactor. At present, the leading process for ferrochrome is that offered by Outokumpu [2].
