Chromium.
The production of charge ferrochromium in an electric furnace consumes 4,000 kilowatt-hours of electric power per ton of alloy produced.1
This process involves smelting ore with coke and adding silica to the charge to create a carbon-saturated alloy with increased silicon content. In comparison, the production of high-carbon ferrochromium requires a higher energy input of 4,600 kilowatt-hours per ton.1
