The Use Of Chromite

Ferrochrome is divided into high carbon ferrochrome according to different carbon content, including loading grade ferrochrome (C≦10%), medium carbon ferrochrome (C≦4.0%), low carbon ferrochrome (C≦0.5%), micro-carbon ferrochrome (C≦0.15%), etc. Commonly used are chromium silicon alloy, chromium nitride and so on. Ferrochrome is mainly used as an alloy additive in steelmaking and used to be added in the late refining stage of steelmaking. Smelting stainless steel and other low carbon steel, must use low and micro carbon ferrochrome, so refined ferrochrome production has been relatively large-scale development. Due to the improvement of the steelmaking process, when AOD method (see refining outside the furnace) is used to produce stainless steel and other steel grades, carbon ferrochrome (mainly charging grade ferrochrome) is loaded into the furnace, so only low and micro-carbon ferrochrome is added in the later period to adjust the composition, so now the focus of ferrochrome production is refining carbon ferrochrome. The introduction of the "Steel industry Development Policy" is a major event in the development of China's steel industry, which will play an important guiding role in the future development of China's steel industry, and is an important cornerstone for promoting the healthy development of the steel industry.
