1. Metallurgical industry
Chromium is hard, often mixed into steel to make hard, corrosion-resistant alloys, mainly used for refining stainless steel, heat-resistant steel, and various electric heating materials.
2. Chemical industry
Various chromium salts produced by processing chromite are the main raw materials in the chemical industry. Chromium salts are one of the main varieties of inorganic salts. It is widely used in daily life. Mainly used in electroplating, tanning, printing, and dyeing, medicine, fuel, catalyst, oxidant, matches, and metal corrosion inhibitor.
3. Refractory and cast iron
Since chromite has a melting point of up to 1900 °c to 2050 °c, it retains its volume at high temperatures and does not react with any slag. Therefore, it can be used as a refractory material, as a lining for steelmaking furnaces and non-ferrous metal smelting furnaces.4. In addition, chromium is also used in cast iron. For example, chrome cast ductile iron.
