Chromium is one of the important strategic materials. It has the characteristics of hard quality, wear resistance, high temperature resistance and corrosion resistance. The uses of its chromite are:
(1) In the metallurgical industry, chromite is mainly used to produce ferrochromium alloys 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 Chromium metal 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, and ships in aviation, aerospace, automotive, shipbuilding, and defense industries.
(2) Among refractory materials? Chromite is used to make chrome bricks, chrome magnesium bricks and other special refractory materials.
(3) In the chemical industry, it is mainly used to produce sodium dichromate? And then to prepare other chromium compounds? Used in pigment, textile, electroplating, leather making and other industries? Can also make catalysts and catalysts. Therefore, there are three kinds of sales channels for chromite, namely, metallurgy industry, refractory industry and chemical industry. The following describes 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. Because of its hard, wear-resistant, high-temperature, and corrosion-resistant characteristics, it has been widely used in the metallurgical industry, refractory materials, and chemical industries.
