Chromium is one of the important strategic materials. It has the characteristics of hardness, wear resistance, high temperature resistance and corrosion resistance. The uses of its chromite ore include:
(1) In the metallurgical industry: chromite is mainly used to produce ferrochrome and metallic chromium. a Ferrochrome is used as a steel additive to produce a variety of high-strength, corrosion-resistant, wear-resistant, high-temperature, and oxidation-resistant special steels such as stainless steel, acid-resistant steel, heat-resistant steel, ball bearing steel, spring steel, tool steel, etc. b 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, and ships in the aviation, aerospace, automobile, shipbuilding, and defense industries.
(2) In refractory materials: chromite is used to make chrome bricks, chrome magnesia 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. It is used in industries such as pigments, textiles, electroplating, and leather making, as well as catalysts and catalysts. There are also three sales channels for chromite: metallurgical industry, refractory industry and chemical industry. The following describes the use and smelting process of ferrochromium and chromium salt from the use of chromite in the metallurgical industry
Chromium is one of the important strategic materials. Because of its hardness, wear resistance, high temperature resistance, and corrosion resistance, it has been widely used in the metallurgical industry, refractory materials and chemical industries.
Our factory mainly focuses on high-carbon ferrochrome, and also has ordinary silicon high-carbon ferrochrome and low-silicon high-carbon ferrochrome.
