Description of Ferrochrome
Ferrochrome (FeCr) is a ferroalloy composed of chromium and iron. It is an important alloy agent in steelmaking. According to different carbon content, Ferrochrome is divided into High Carbon Ferrochrome (carbon content of 4~8%), Medium Carbon Ferrochrome (carbon content of 0.5~4%), Low Carbon Ferrochrome or lc ferro chrome (carbon content of 0.15~0.50%), Micro Carbon Ferrochrome (with a carbon content of 0.06%), Ultra-Fine Carbon Ferrochrome (with a carbon content of less than 0.03%), as well as silicon-chromium alloy, nitride ferrochromium, etc.

Ferrochromium is a ferroalloy with chromium and iron as the main components. It is one of the main alloying agents used in the iron and steel industry. In addition to the main components of chromium and iron, it also contains impurities such as carbon, silicon, sulfur, and phosphorus.
FeCr contains 55% to 75% chromium and is divided into high carbon (4% to 10% C), medium carbon (0.5% to 4% C), low carbon (>0.15% to 0.5% C), and low carbon (>0.15% to 0.5% C) according to the carbon content. Micro-carbon (≤0.15%C) FeCr metal.
Ferrochrome high carbon is also called carbon ferrochrome, and medium, low, and micro-carbon ferrochrome alloy is also called refined ferrochromium. High-carbon ferrochrome produced from chrome ore with a low chromium-to-iron ratio, containing 50% to 55% of Cr is called charge-grade ferrochrome alloy, and nitrogen-containing ferrochromium containing N2% to 10% is used as a nitrogen alloying agent.
The addition of chromium to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel. Chromium is contained in many sheets of steel with special physical and chemical properties. Chromium in steel is added with ferrochromium.
High carbon ferrochrome is used as an alloying agent for ball steel (0.5%~1.45%Cr), tool steel, die steel (5%~12%Cr), and high-speed steel (3.8%~4.4%Cr), which can improve the quenching of steel. permeability, increase the wear resistance and hardness of steel. Adding chromium to cast iron can increase hardness and improve wear resistance, and chromium content of 0.5% to 1.0% can improve its mechanical properties. High carbon FeCr alloy and charge grade ferrochromium is used in large quantities as the charge for smelting stainless steel (AOD or VOD method) to reduce production costs.
Medium and ferro chrome low carbon is used in the production of medium and low-carbon structural steel, carburized steel, gears, high-pressure blower blades, valve plates, etc.
Micro-carbon ferrochrome is used in the production of stainless steel, acid-resistant steel, heat-resistant steel, and electrothermal alloys.
Low-carbon ferrochrome is an iron alloy composed of iron and silicon. LC ferrochrome alloy is an iron-silicon alloy smelted in an electric furnace using coke, steel shavings, and quartz (or silicon dioxide) as raw materials. Because silicon and oxygen are easy to synthesize silica, low-carbon ferrochromium is often used as a deoxidizer in steelmaking. At the same time, since SiO2 releases a lot of heat during the formation process, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, low-carbon ferrochrome can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. In ferroalloy production and the chemical industry, low-carbon ferrochrome is often used as a reducing agent.
Low-carbon Ferrochromium (FeCr)
Chrome ore also accounts for a large proportion of the ferrochrome production. Chromium ore resources in China are very few. In 2013, the consumption of chromium ore was nearly 14 million tons, and the domestic supply was only about 2 million tons. The rest was settled by imports. The cost of chromium ore accounts for about 60% of the production cost of ferrochrome alloys in China, the cost of electricity accounts for about 25%-30%, and the cost of coke accounts for about 10%-15%.
