Khoom Description
Vanadium tau tshawb pom hauv 1801 los ntawm AM del Rio. Vanadium cov ntsiab lus nyob rau hauv lub ntiaj teb lub crust yog 0.015 %, nws yog heev ntau yam, tab sis tawg nyob rau hauv pob zeb minerals. Cov neeg siv khoom tseem ceeb ntawm vanadium yog ferrous metallurgy (txog 95% ntawm cov hlau tsim). Vanadium yog siv los ua ib qho tseem ceeb alloying ntsiab nyob rau hauv melting ntawm high-ceev, alloyed cuab tam thiab buildal txias-resistant steels. Vanadium cov ntsiab lus txog li 0. Vanadium yog ob qho tib si deoxidizing thiab carbide-forming keeb. Los ntawm kev tsim cov carbides, vanadium ua rau cov qauv steel ntau zoo-grained, stabilizes ferrite hauv austenitic steels ntawm qhov kub thiab txias thiab cov ntsiab lus carbon tsawg. Vanadium kuj tseem siv rau alloying cam khwb cia hlau. Nws tiv thaiv graphitization, stabilizes cementite thiab nce qhov tob ntawm cam khwb cia hlau txias, thaum ua kom nws cov toughness. Vanadium yog siv rau alloying titanium, niobium, thiab chromium-raws li alloys dav siv nyob rau hauv aviation, foob pob ua ntxaij thiab chaw engineering. Ntshiab metallic vanadium yog siv hauv kev lag luam nuclear thiab hauv kev tsim khoom siv hluav taws xob.
Ferrovanadiumnce hardenability thiab tsis kam mus rau tempering. Nws yog siv los txhim kho toughness, tsis kam ntawm steel rau alternating loads. Ferrovanadium kuj tseem siv tau kom tau txais cov qauv zoo ntawm cov hlau.
Tsuas yog oxide zaj duab xis tarnish thiab cov kab ntawm cov chaw tsim khoom raug tso cai rau ntawm qhov chaw. Kev kis kab mob los ntawm cov xuab zeb, slag thiab lwm yam khoom txawv teb chaws yuav tsum tsis suav nrog.
Ferrovanadium tau xa hauv cov pob uas hnyav tsis tshaj 5 kg. Tus nqi nplua dhau 10-mm sieve yuav tsum tsis pub tshaj 5% ntawm cov khoom loj.
Ntawm cov neeg siv khoom thov, ferrovanadium tuaj yeem tsim los ntawm cov chav kawm sib txawv raws li cov lus hauv cov lus qhia.
