Uses Of Chromite

Chromium is one of the important strategic materials. It has the characteristics of hardness, wear resistance, high temperature resistance and corrosion resistance. Its chromite uses are: [4]

(1) In the metallurgical industry? Chromite is mainly used to produce ferrochromium and metallic chromium. a Ferrochromium alloy is used as a steel additive to produce a variety of special steels with high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance? Such as stainless steel, acid-resistant steel, heat-resistant steel, ball bearing steel, spring steel, tool steel, etc. b Metal chromium is mainly used for smelting special alloys with cobalt, nickel, tungsten and other elements. These special steels and special alloys are indispensable materials for the production of guns, missiles, rockets, ships, etc. in the aviation, aerospace, automobile, shipbuilding and defense industries.

(2) Among the refractories? Chromite is used to make chrome bricks, chrome-magnesium bricks and other special refractories.

(3) In the chemical industry, it is mainly used to produce sodium dichromate, and then to prepare other chromium compounds. It is used in pigments, textiles, electroplating, leather and other industries. Therefore, there are also three sales channels for chromite, namely metallurgical industry, refractory industry and chemical industry. The following introduces the use and smelting process of ferrochromium and chromium salts from the use of chromite in the metallurgical industry

Chromium is one of the important strategic materials. It has been widely used in metallurgical industry, refractory materials and chemical industry due to its properties of hardness, wear resistance, high temperature resistance and corrosion resistance.
