Low Carbon Ferrochrome Production - etimet.com

Low Carbon Ferrochrome Production (LC FeCr) LC FeCr (Low Carbon Ferrochrome) is a ferro-alloy used to regulate the ratio of Chromium in steel production without Carbon and other unwanted ingredients. Due to high quality it is a reliable and economical alternative instead of metallic Chromium in Superalloy production.

Ferrochrome - Wikipedia

Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore (an oxide of chromium and iron) is reduced by coal and coke to form the iron-chromium alloy. The heat for this reaction can come from several forms, but typically from the electric arcformed between the tips of the electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2,800 °C (5,070 °F). In the process of smelting, huge amounts of electric…
