Ferrochrome is an iron alloy composed of chromium and iron, and is an important alloy additive in steelmaking. According to different carbon content, ferrochrome is divided into high carbon ferrochrome (carbon content is 4~8%), medium carbon ferrochrome (carbon content is 0.5~4%), low carbon ferrochrome (carbon content is 0.15~0.50%), micro-carbon ferrochrome (carbon content is 0.06%), ultra-carbon ferrochrome (carbon content is less than 0.03%), metal chromium, silicon chromium alloy, 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. 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.
Micro-carbon ferrochrome is mainly used in the production of stainless steel, acid-resistant steel and heat-resistant steel. Smelting methods include electric silicon thermal process and thermal blending process. Medium and low carbon ferrochrome is used in the production of medium and low carbon structural steel, chromium steel, alloy structural steel. High carbon ferrochrome (including recycled ferrochrome)
The main uses of ferrochrome powder are:
(1) Used as an alloying agent for ball steel, tool steel and high-speed steel with high carbon content to improve the hardenability of steel and increase the wear resistance and hardness of steel;
(2) Used as an additive to cast iron to improve the wear resistance and hardness of cast iron, while making cast iron have good heat resistance;
(3) Used as a chrome-containing raw material for the slag-free production of silico-chromium alloy and medium, low and micro-carbon ferrochrome;
(4) chrome-containing materials used for electrolysis production of metal chromium;
(5) Used as raw materials for oxygen blowing stainless steel smelting.
