Vanadium yog ib qho tseem ceeb alloying ntsiab feem ntau siv hauv kev lag luam steel. Vanadium-muaj steel muaj cov khoom zoo xws li lub zog siab, toughness, thiab zoo hnav tsis kam. Yog li ntawd, nws yog dav siv nyob rau hauv machinery, tsheb, shipbuilding, railways, aviation, txuas hniav, hluav taws xob technology, tiv thaiv kev lag luam thiab lwm yam lag luam. Nws siv nyiaj li ntawm 1% ntawm kev siv vanadium. 85%, kev lag luam steel tso nyiaj rau feem ntau ntawm vanadium siv. Qhov kev thov ntawm kev lag luam steel ncaj qha cuam tshuam rau kev lag luam vanadium. Txog 10% ntawm vanadium yog siv los tsim cov titanium alloys xav tau los ntawm kev lag luam aerospace. Vanadium tuaj yeem siv los ua tus stabilizer thiab ntxiv dag zog rau hauv titanium alloys, ua cov titanium alloys zoo heev thiab yas. Tsis tas li ntawd, vanadium feem ntau yog siv los ua catalyst thiab colorant hauv kev lag luam tshuaj. Vanadium kuj tseem siv rau hauv kev tsim cov roj teeb hydrogen rechargeable lossis vanadium redox roj teeb.
Vanadium-nitrogen alloy yog ib qho khoom siv tshiab uas tuaj yeem hloov ferrovanadium rau kev tsim cov hlau microalloyed. Qhov sib ntxiv ntawm vanadium nitride rau hlau tuaj yeem txhim kho cov khoom siv kho tshuab zoo ntawm cov hlau xws li lub zog, toughness, ductility thiab thermal qaug zog tsis kam, thiab ua rau cov hlau muaj qhov zoo weldability. Txhawm rau ua tiav tib lub zog, ntxiv vanadium nitride txuag 30 mus rau 40% ntawm vanadium ntxiv, yog li txo cov nqi.
Vanadium-nitrogen alloy hloov ferrovanadium rau vanadium alloying, uas tuaj yeem txhim kho lub zog ntawm cov hlau tuav tsis muaj kev cuam tshuam cov yas thiab weldability. Nyob rau tib lub sijhawm, nws tuaj yeem txo qhov nyiaj ntawm alloy ntxiv thiab txo cov nqi alloying thaum ua kom muaj zog ntawm cov hlau tuav. Yog li ntawd, Tam sim no, ntau lub tuam txhab steel hauv tsev tau siv vanadium-nitrogen alloy los tsim cov hlau muaj zog. Nyob rau hauv xyoo tas los no, vanadium-nitrogen alloying thev naus laus zis kuj tau siv rau hauv cov hlau tsis-quenched thiab tempered steel, high-strength tuab-walled H-shaped steel, CSP cov khoom thiab cov cuab yeej hlau. Cov khoom lag luam uas tsim los siv vanadium-nitrogen micro-alloying thev naus laus zis tau zoo heev thiab ruaj khov zoo, tsis tshua muaj nqi alloying, thiab cov txiaj ntsig tseem ceeb ntawm kev lag luam, uas txhawb kev txhim kho cov khoom steel.
