Of low carbon ferrochrome, iron and silicon iron alloy. Low carbon ferrochrome is coke, steel scrap, quartz (or silica) as raw material, made of iron smelting furnace silicon alloy. Because silicon and oxygen is very easy synthesis of silicon dioxide, low carbon ferrochrome used in steelmaking for deoxidation agent, at the same time release a large amount of heat generated due to SiO2 deoxy at the same time, improve the temperature of molten steel is also beneficial. The same time, low carbon ferrochrome can be added as an alloying element agent, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon into low-carbon ferrochrome in ferroalloy production and chemical industry, commonly used as a reducing agent. 
 (1) used as a deoxidizer and alloying agent in the steel industry. In order to obtain the chemical composition of qualified steel and guarantee the quality of the steel must be carried out in the final stages of the steelmaking deoxidation, silicon, and oxygen chemical affinity between, and thus low carbon ferrochrome is the steelmaking strong deoxidizer for precipitation and diffusion deoxidation. Add a certain amount of silicon in the steel, can significantly improve the steel strength, hardness and elasticity, so the smelting structural steel (Si 0.40-1.75%), tool steel (including SiO.30-1.8%), spring steel (including SiO.40-2.8%) and transformers using silicon (Si 2.81-4.8%) low carbon ferrochrome used as an alloying agent. While improving the inclusion morphology to reduce the element content of the gas in the liquid steel is to improve steel quality, reducing costs, saving iron technology. Especially suitable for continuous casting of molten steel deoxidation requirements of Practice has proved that low carbon ferrochrome not only meet the steelmaking deoxidation requirements, and also has the desulfurization performance with advantages than significant penetrating power. 
 In addition, in the steel industry, the use of low carbon ferrochrome powder ene burned at high temperatures can release a lot of heat this feature, often as a the ingot cap heating agent to enhance the quality and recovery of the ingot. 
 (2) used as the iron industry gave birth to the agent and nodulizer. Cast iron is an important modern industrial metal materials, it is cheaper than steel, easy to melt smelting, with excellent casting and much better than steel seismic capacity. Ductile iron, the mechanical properties at or near the mechanical properties of steel. A certain amount of low-carbon ferrochrome in cast iron to prevent the formation of iron carbide, and promote the precipitation of graphite and ball, and thus in ductile iron production, low carbon ferrochrome is an important inoculant (to help the precipitation of graphite) and nodulizer. 
 (3) used as a reducing agent in the ferroalloy production. Chemical affinity between not only silicon and oxygen, low carbon content and high silicon low-carbon ferrochrome. Therefore, the high silicon low-carbon ferrochrome (or silicon alloys) is commonly used as a reductant in the production of low-carbon iron alloy in the ferroalloy industry. 
 (4) 75 # low carbon ferrochrome Pidgeon magnesium often used for high-temperature smelting process of magnesium metal, magnesium replacement CaO.MgO out of every ton of metal magnesium is necessary to consume about 1.2 tons of low carbon chromium iron, magnesium metal production plays a big role. 
 (5) use in other areas. Pulverized or atomized low-carbon ferrochromium powder, can be used as the suspended phase in the mineral processing industry. In the electrode manufacturing can be used as electrode coatings. Can be used in the manufacture of silicone products such as high silicon low-carbon ferrochrome in the chemical industry. 
 In these applications, the steel industry, foundry industry and ferroalloy industry is the largest user of low carbon ferrochrome. They are consuming a total of about 90% of low-carbon ferrochrome. In the various grades of low carbon ferrochrome, currently the most widely used is 75% low carbon ferrochrome. In the steel industry, each producing 1t of steel is about consume 3-5kg75% of low-carbon ferrochrome. Low carbon ferrochrome has been widely used in the steel industry, foundry industry and other industrial production.
