Dab tsi yog Kev Siv Chromite
Cov kev siv tseem ceeb ntawm chromite yog raws li hauv qab no.
(1) Hauv kev lag luam metallurgy
Cov kev cai dav dav chromite qib Cr2O338% ~ 45%, Cr / Fe Ntau dua lossis sib npaug rau 2, feem ntau yog siv los tsim chromite alloy thiab hlau chromium. Chromium hlau alloy raws li cov additives ntawm steel ntau lawm ntau lub zog, corrosion kuj, hnav tsis kam, kub tsis kam, oxidation kuj ntawm tshwj xeeb steel, xws li stainless hlau, acid steel, kub resistant steel, pob bearing steel, caij nplooj ntoos hlav steel. , cuab yeej steel thiab lwm yam. Chromium hlau yog tsuas yog siv rau smelting tshwj xeeb alloys nrog cobalt, nickel, tungsten thiab lwm yam khoom. Cov hlau tshwj xeeb thiab cov alloys tshwj xeeb no yog cov khoom siv tsis tau rau aviation, aerospace, automotive, shipbuilding, thiab tiv thaiv kev lag luam tsim cov phom, missiles, foob pob ua ntxaij, nkoj thiab lwm yam.

(2) Rau cov khoom siv refractory
Feem ntau, qib ntawm chromite yog Cr2O330%-35%, thiab SiO2 tsawg dua 5%, uas yog siv los tsim chrome cib. Chrome-magnesia bricks thiab tag nrho cov khoom siv hluav taws xob qib siab refractory, nrog rau lwm cov ntaub ntawv tshwj xeeb refractory, tau dav siv hauv qhib lub qhov cub, induction rauv, metallurgical converter thiab cement kev lag luam teb rauv hauv ob sab phlu.

(3) Hauv kev lag luam chemical
Cov kev cai dav dav chromite qib Cr2O3 Ntau dua lossis sib npaug li 30%, Cr / Fe Ntau dua lossis sib npaug li 2, feem ntau yog siv los tsim sodium dichromate, thiab tom qab ntawd tsim lwm cov chromium tebchaw, siv hauv pigments, textiles, electroplating, tanning thiab lwm yam lag luam, tab sis kuj los tsim cov catalysts.
Sodium dichromate
76% ntawm lub ntiaj teb chromite noj yog siv nyob rau hauv metallurgical kev lag luam, 13% nyob rau hauv refractories thiab 11% nyob rau hauv kev lag luam tshuaj. Txog 80% ntawm Tuam Tshoj txoj kev lag luam metallurgical, 4% rau cov ntaub ntawv refractory, 16% rau kev lag luam tshuaj, kuj tseem muaj me me ntawm chromium ore rau kev lag luam casting.
