Low Carbon Ferro Chrome

Ferrochrome is an iron alloy with chromium and iron as its main components. It is one of the main alloying agents used in the iron and steel industry, and contains carbon, silicon, sulphur, phosphorus and other impurities in addition to the main components of chromium and iron. Ferrochrome contains 55% ~ 75% of chromium, according to the carbon content is divided into high-carbon ferrochrome (C: 4% ~ 10%), medium-carbon ferrochrome (C: 0.5% ~ 4%), low-carbon ferrochrome (C: 0.15% ~ 0.5%) and micro-carbon ferrochrome (C ≤ 0.15%). High-carbon ferrochrome is also known as carbon ferrochrome, medium-carbon, low-carbon and microcarbon ferrochrome is also known as refined ferrochrome. One kind of high-carbon ferrochrome (Cr: 50-55%) produced by chromite ore with low ferrochrome ratio is known as furnace-grade ferrochrome, and there is also a kind of nitrogen-containing ferrochrome (N: 2-10%) used as nitrogen alloying agent, also known as ferrochrome nitride.

Global Low Carbon Ferro Chrome is widely used in electronics, optical fibre, solar energy products, construction, medical, chemical, mechanical and metallurgical, rubber and insulating materials, high temperature coatings and other industrial and civil applications.

1. Deoxidizer: Due to the easy combination of silicon and oxygen to form silicon dioxide, low carbon ferrochrome is commonly used as a deoxidizer in the steel refining process. At the same time, the production of silicon dioxide releases a large amount of heat, which helps to increase the temperature of the molten steel.

2. Alloying element additive: Low carbon ferrochrome is widely used as an additive for alloying elements in the field of low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel.

3. Reductant: In the production of iron alloys and in the chemical industry, low carbon ferrochrome is commonly used as a reductant.

The smelting methods of low carbon ferrochrome and micro carbon ferrochrome include the electro silicon thermal, The Perrin process and vacuum solid state decarburisation method.

Electrosilicon thermal production of refined ferrochrome, also known as the desiliconization method, is a method of smelting refined ferrochrome by adding chrome ore, lime and silicon chromium alloy into an electric arc furnace.

The Perrin process of smelting micro-carbon ferrochrome, also known as the hot mixing method, is a kind of furnace desilication method of smelting micro-carbon ferrochrome. In 1938 Frenchman Pollan successfully researched a kind of iron ladle with silica reductant in the chrome ore-lime melt of chromium, iron and production of micro-carbon ferrochrome method. Generally, two different electric furnaces are used to melt liquid silicon-chromium alloy and chromite-lime melt, and then mix the two in the reaction tank, relying on the sensible heat of the raw materials and the heat released by the chemical reaction to maintain the high temperature of the smelting process. As a result of this process, micro-carbon ferrochrome with less than 0.8% silicon and as low as 0.02% carbon can be obtained1. This method plays a significant role in producing ferrochrome alloys for various industrial applications.

The vacuum solid decarburisation method, also known as the vacuum micro carbon ferrochrome method, is based on high-carbon ferrochrome as raw material, after crushing, ball milling, oxidative roasting, batching, mixing (adding binder), moulding, drying, vacuum smelting, etc. to produce qualified vacuum micro-carbon ferrochrome. The product qualification rate of low carbon ferrochrome produced by the vacuum solid decarburisation method is above 98%.

Global ferrochromium production capacity relies on demand and resource distribution. The combined output of China, South Africa, Kazakhstan, and India accounts for 86.2% of the global total, and the output distribution is relatively concentrated. In China's existing ferrochrome production capacity distribution and structure, the main production capacity is concentrated in Inner Mongolia, Shanxi, Guizhou, Hunan, Sichuan, Guangxi and other provinces.

The world's major exporters of low-carbon ferro chromium include Russia, Kazakhstan, Turkey, China and Brazil.
