Ferro Chrome (FeCr)

Ferro Chrome (FeCr)

Ferro Chrome (FeCr) Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The ferrochrome is produced by electric arc melting of chromites, an iron magnesium chromium oxide and the most important chromium ore. Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromites resources.ing on the raw material basis. Essentially all FeCr is produced in submerged arc furnaces, while the role ofpetitive technologies like DC is limited. In all furnaces fluxes are used to optimize the slagposition. Vital characteristics are smelting point, electric conductivity and viscosity. The mainponents of FeCr slag are SiO2, Al2O3 and MgO. Additionally it consists of Cr-, Fe-oxides and CaO.Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The Producer od stainless steel & tool steel are the largest consumer of ferrochrome and charge is chromium that confers upon stainless steel its remarkable corrosion resistance. Out of the total world chrome ore output about 95% is used to produce ferrochrome for the metallurgical industry, with 2% used in chemical industry and the balance 3% in the refractory and foundry industry.INR5000MT FeCr price correction likely in short term.
