low carbon ferrochrome process

Ferrochrome - Wikipedia

In the process of smelting, huge amounts of electricity are consumed, making production in countries with high power cost very expensive. Tapping of the material from the furnace takes place intermittently. When enough smelted ferrochrome has accumulated in the hearth of the furnace, the tap hole is drilled open and a stream of molten metal and ...

History. Chromium is unusual among metals in that its ores and chemical compounds were used extensively long before the pure metal was prepared. As early as 1800, they were used to make pigments and chemicals for leather tanning, and in 1879 they were successfully used as refractories for the lining of steelmaking furnaces.
