Chromium is one of the first strategic materials. It is characterized by hardness, wear resistance, high temperature resistance and corrosion resistance. The USES of its chromite are:
(1) In the metallurgical industry? Chromite is primarily used to produce ferrochrome and chromium metal. A chromium iron alloy as steel additive to produce a variety of high strength, corrosion resistance, wear resistance, high temperature resistance, oxidation resistance of special steel? Such as stainless steel, acid resistant steel, heat resistant steel, ball bearing steel, spring steel, tool steel and other B metal chromium is primarily used with cobalt, nickel, tungsten and other elements exercise special alloy. 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 national defense industries.
(2) In refractories? Chromite powder is used in the manufacture of chrome bricks, chrome magnesite bricks and other special refractory materials.
(3) Used primarily in the chemical industry to produce sodium dichromate? To make other chromium compounds? Used in pigment, textile, electroplating, leather making and other industries. Also can manufacture catalyst and catalyst agent and so on. So there are three ways of selling ferrochrome powder? Namely? Metallurgical, refractory, and chemical industries.
Chromium is one of the first strategic materials, because it has hard, wear resistance, high temperature resistance, corrosion resistance and other characteristics, in the metallurgical industry, refractories and chemical industry has been widely used.
