Chromium is one of the important strategic materials. Because of its properties of hardness, wear resistance, high temperature resistance and corrosion resistance, it has been widely used in metallurgical industry, refractory material and chemical industry.
In the metallurgical industry, chromite is mainly used to produce ferrochromium alloy and metallic chromium. Ferrochromium is used as an additive to steel to produce a variety of high-strength, corrosion-resistant, wear-resistant, high-temperature-resistant, and oxidation-resistant special steels, such as stainless steel, acid-resistant steel, heat-resistant steel, ball bearing steel, spring steel, tool steel, etc. Metal chromium is mainly used to smelt 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 aviation, aerospace, automobile, shipbuilding and national defense industries.
In refractory materials, chromite is used to make chrome bricks, chrome-magnesia bricks and other special refractory materials. In the chemical industry, chromite is mainly used to produce sodium dichromate, and then to produce other chromium compounds, which are used in pigments, textiles, electroplating, tanning and other industries, and can also be used to make catalysts.
