Ferrochrome is one of the ferroalloy include 55%-75% chrome, according to different carbon content can be divided into High-carbon (4%-10%C), Middle-Carbon (0.5%-4%C), Low-Carbon (0.15-0.5%C), Micro-Carbon (≦0.15%C).
The production of steel is the largest consumer of ferrochrome, especially the production of stainless steel with chromium content of 10 to 20%, over 80% of the world's ferrochrome is utilised in the production of stainless steel, this is the main application of ferrochrome. Adding the Chrome into steel can improve the oxidation resistance and corrosion resistance obviously of steel and can produce various special steel with high intensity, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance such as stainless steel, acid resistant steel, heat resistant steel, ball bearing steel, spring steel and tool steel and etc.
Ferrochrome used to be added in the later stage of steelmaking as the alloy additive, to smelt the low-carbon steel such as stainless steel must use the low or micro-carbon ferrochrome, therefore, the production of refined ferrochrome once achieved large-scale development. Due to the improvement of the steelmaking process, now when use the AOD method to produce the steel such as stainless steel, commonly use the carbon ferrochrome load furnace, therefore, only need to add low-carbon or micro-carbon ferrochrome to adjust the composition in the later stage, so now the focus of ferrochrom production is to smelt the carbon ferrochrome. For the carbon ferrochrome, it always smelt in a reduction furnace,using the coke as reducing agent,silica or bauxite as a flux.
