 1.Introduction:

  Ferro chromium (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium.

   The ferro chromium is produced by electric arc melting of chromites, an iron magnesium chromium oxide and the most important chromium ore. Most of the world's ferro chromium is produced in South Africa, Kazakhstan and India, which have large domestic chromites resources. Increasing amounts comes from Russia and China.

 

2.Properties:

Chromium is mainly used to improve the antioxidation and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhension oxide film. Then it stops being oxidized or decelerates being oxidized. Micro-carbon ferro chrome is applied to making stainless steel, acid-resistant steel and heat resistant steel.

3.Application:

(1) Over 80% of the world's ferro chromium is utilised in the production of stainless steel. The average chrome content in stainless steel is approximately 18%.

 

(2) It is also used when it is desired to add chromium to carbon steel.

 

(3) High Carbon FeCr produced from high grade ore found in Kazakhstan (among other places) is more commonly used in specialist applications such as engineering steels where a high Cr to Fe ratio and minimum levels of other elements such as Sulfur, Phosphorus and Titanium are important and production of finished metals takes place in small electric arc furnaces compared to large scale blast furnaces.
