PRODUCTION, CHARACTERISTICS AND USE OF .
World high carbon ferrochrome production, charge chrome and HCFeCr, was million tonnes in 2005. The production increased by per cent from the year 2004. Almost all ferrochrome is produced in submerged electric arc furnaces. The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral.
SOME ASPECTS OF THE PRODUCTION OF FERROCHROME .
In the conventional production of stainless steels, chromium is generally introduced to the process in the form of CrFeCSi alloys, principally as highcarbon ferrochrome or charge chrome. The level of carbon and silicon in the above alloys is important especially when refining is carried out by blowing oxygen in the melt.
