Ferrochrome
Ferrochrome, ib qho tseem ceeb alloy additive rau steelmaking, yog ib tug hlau alloy muaj xws li chromium thiab hlau. Raws li cov ntsiab lus sib txawv, ferrochrome tau muab faib ua cov pa roj carbon ntau ferrochrome (cov ntsiab lus carbon yog 4 ~ 8%), nruab nrab carbon ferrochrome (cov ntsiab lus carbon yog 0.5 ~ 4%), qis carbon ...
Ferrochrome, ib qho tseem ceeb alloy additive rau steelmaking, yog ib tug hlau alloy muaj li ntawm chromium thiab hlau. Raws li cov ntsiab lus sib txawv, ferrochrome tau muab faib ua cov pa roj carbon monoxide siab (cov ntsiab lus carbon yog 4 ~ 8%), nruab nrab carbon ferrochrome (cov ntsiab lus carbon yog 0.5 ~ 4%), cov pa roj carbon tsawg ferrochrome (cov ntsiab lus carbon yog { {5}}.15~0.5{{10}}%), micro-carbon ferrochrome (carbon ntsiab lus yog 0.06%), ultra-carbon ferrochrome (cov ntsiab lus carbon tsawg dua 0.03 %), thiab silicon chromium alloy, ferrochrome nitride, thiab lwm yam.
Chromium cov ntaub ntawv
Chromium cov peev txheej Kev nplua nuj ntawm chromium nyob rau hauv lub ntiaj teb crust yog 0.035%, tab sis qhov tshwm sim chromium ore muaj cov ntsiab lus chromium siab. Cov khoom siv chromite nyob ze rau sab qaum teb-sab qab teb fold siv nyob rau hauv lub ntiaj teb account rau ntau tshaj 95% ntawm lub ntiaj teb no tag nrho, thiab cov khoom siv chromium hauv Precambrian fold siv khiav los ntawm East Africa account rau 94% ntawm lub ntiaj teb tag nrho.
Ural Varissi quav siv nyiaj txog li 2%, thiab Alpine fold siv nyiaj li 2% ntawm lub ntiaj teb tag nrho. Lub geological tej yam kev mob ntawm chromium ore mineralization nyob rau hauv Tuam Tshoj tsis zoo tagnrho, thiab chromite siv los ntawm sab qab teb mus rau sab qaum teb tsis tau pom nyob rau hauv Cambrian geological cheeb tsam.
Cov chromite deposits nyob rau hauv Xizang thiab Yunnan yog nyob rau hauv lub fold siv ntawm Alpine Age.
Cov chromite deposits nyob rau hauv Xinjiang-Gansu thiab Qinghai-Inner Mongolia yog nyob rau hauv lub ze rau sab hnub tuaj-sab hnub poob fold siv ntawm Hercynian hnub nyoog. Tsis muaj leej twg muaj cov xwm txheej los tsim cov deposits loj heev. Lub ntsiab chrome-muaj cov ntxhia ntawm cov nqi lag luam yog chrome-spinel, feem ntau tsis raug xa mus rau chromite. Muaj peb yam tseem ceeb tshaj plaws chromium spinel minerals: magnesium chromite (Mg, Fe) Cr2O4, hard chromite spinel(Mg, Fe)(Cr, Al)2O4 and aluminum chromite Fe(Cr, Al)2O4. The largest user of chromium ore is the ferroalloy industry, which accounts for about 80% of the total production of chromium ore. It is called metallurgical grade chromium ore in the chrome ore market. High-quality metallurgical grade chromium ore requires Cr2O3>48%, S<0.1%, P<0.1%, Cr2O3: FeO>3 to produce ferrochrome containing Cr>70%. Vim qhov txo qis ntawm chrome-nplua nuj ore, cov ore nrog tsawg chrome-hlau piv yog qhov nce. Lawv tsuas yog siv tau los ua cov nqi ferrochrome.
