Chromium is a silver-white metal with a high melting point. Thanks to its hardness and resistance to corrosion, it has become one of the most important and indispensable industrial metals and is widely used in everyday life. In this article, we’ll take a look at the 5 primary uses of chromium.
Chromium is hard, often mixed into steel to make a hard and corrosion-resistant alloy, mainly used for refining stainless steel, heat-resistant steel, and various electric heating element materials.
When stainless steel encounters corrosive substances, a fine and solid chromium oxide film will be formed on the surface to protect the internal metal from corrosion. Some stainless steels can maintain their excellent performance even at a high temperature of 800 ° C. Chrome steel is a good material for manufacturing machinery, tanks, and armored vehicles.
Various chromium salts processed from chromite are the main raw materials in the chemical industry. Chromium salt is one of the main varieties of inorganic salts. It is mainly used in electroplating, tanning, printing, and dyeing, medicine, fuel, catalysts, oxidants, matches, and metal corrosion inhibitors.
At the same time, metallic chromium has become one of the most important electroplated metals. Without the physical properties provided by the chrome layer, the service life of most parts will be greatly shortened due to wear, corrosion and other reasons, and must be replaced or repaired frequently. Therefore, chrome plating is more and more widely used in industrial manufacturing.
Because the melting point of chromite is as high as 1900 ℃ to 2050 ℃, it can keep the volume unchanged at high temperature and it does not react with any slag. Therefore, it can be used as a kind of refractory material for the lining of steel-making furnaces and non-ferrous metal smelting furnaces.
Therefore, in terms of refractory materials, chromite is used to make chrome bricks, chrome magnesium bricks, and other special refractory materials.
Chromium cast iron refers to adding chromium element to iron element, in order to change the physical structure and chemical properties of iron, making its application field wider.
The amount of added chromium element is different, and the formed chromium cast iron has different chemical properties. According to the content of chromium element, it can be divided into low chromium cast iron, medium chromium cast iron, and high chromium cast iron.
Car brake pads refer to the friction material fixed on the brake drum or brake disc rotating with the wheel. In the automotive industry, chromium is involved in the production of car brake pads.

Chromium ni chuma cha rangi ya fedha-nyeupe chenye kiwango cha juu cha kuyeyuka. Kwa sababu ya ugumu wake na upinzani wake kwa kutu, imekuwa moja ya metali muhimu na muhimu ya viwanda na hutumiwa sana katika maisha ya kila siku. Katika makala hii, tutaangalia matumizi matano ya msingi ya chromium. Chromium ni ngumu, mara nyingi kuchanganywa katika chuma kufanya ngumu na kutu-upinzani alloy, hasa kutumika kwa ajili ya kusafisha chuma cha pua, chuma joto-upinzani, na vifaa mbalimbali umeme joto kipengele. Wakati chuma cha pua hukutana na vitu vyenye kutu, filamu nzuri na thabiti ya oksidi ya kromu itaundwa juu ya uso ili kulinda chuma cha ndani kutoka kwa kutu. Chuma cha chromium kinaweza kuhifadhi utendaji wake bora hata kwa joto la juu la 800 ° C. Chuma cha chromium ni nyenzo nzuri kwa kutengeneza mashine, mizinga, na magari ya kivita. Chumvi mbalimbali za kromu zinazotengenezwa kutokana na kromiti ndizo malighafi kuu katika viwanda vya kemikali. Chumvi ya kromu ni mojawapo ya aina kuu za chumvi zisizo za kikaboni. Ni hasa kutumika katika electroplating, tanning, uchapishaji, na dyeing, dawa, mafuta, catalysts, oxidants, mechi, na chuma kutu inhibitors. Wakati huohuo, chromium ya chuma imekuwa mojawapo ya metali muhimu zaidi zinazopakwa umeme. Bila mali ya kimwili inayotolewa na safu ya chrome, maisha ya huduma ya sehemu nyingi yatapunguzwa sana kwa sababu ya kuvaa, kutu na sababu zingine, na lazima ibadilishwe au kurekebishwa mara kwa mara. Kwa hiyo, chrome plating ni zaidi na zaidi sana kutumika katika utengenezaji wa viwanda. Kwa sababu ya kiwango cha kuyeyuka cha chromium, inaweza kufikia 1900 ° C hadi 2050 ° C, inaweza kuweka kiasi chake bila kubadilika kwa joto la juu na haitikii na slag yoyote. Kwa hiyo, inaweza kutumika kama aina ya refractory nyenzo kwa ajili ya lining ya chuma-kufanya tanuru na si chuma chuma kutengenezwa tanuru. Kwa hiyo, katika suala la vifaa refractory, chromite ni kutumika kufanya matofali chrome, chrome magnesiamu matofali, na vifaa vingine maalum refractory. Chuma cha chuma cha chromium ni kuongeza chembe ya chromium kwa chuma, ili kubadilisha muundo wa kimwili na mali ya kemikali ya chuma, na kupanua uwanja wake wa matumizi. Kiasi cha kipengele cha chromium kilichoongezwa ni tofauti, na chuma cha chuma cha chromium kilichoundwa kina mali tofauti za kemikali. Kulingana na maudhui ya elementi ya chromium, inaweza kugawanywa katika chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma cha chuma. Brake pads ya gari inahusu nyenzo ya msuguano iliyowekwa kwenye ngoma ya breki au diski ya breki inayozunguka na gurudumu. Katika viwanda vya magari, chromium inahusika katika utengenezaji wa pads za breki za magari. Asante kwa kusoma makala yetu na tunatumaini inaweza kuwa na manufaa kwako.
