Khoom Description
Ferrovanadium yog cov hlau alloy uas tau txais los ntawm kev txo cov vanadium pentoxide hauv lub cub hluav taws xob nrog cov pa roj carbon monoxide, thiab tuaj yeem tau txais los ntawm kev txo qis ntawm vanadium pentoxide los ntawm hluav taws xob cub hluav taws xob silicon thermal.
Nws yog dav siv los ua ib qho khoom siv ntxiv rau smelting vanadium-muaj alloy steels thiab alloy cam khwb cia hlau, thiab tau siv nyob rau hauv xyoo tas los no los ua cov hlau nplaum ruaj khov.
Ferrovanadium feem ntau yog siv los ua cov khoom siv alloying rau steel ua.
Tom qab ntxiv vanadium hlau rau steel, hardness, lub zog, hnav tsis kam thiab ductility ntawm cov hlau tuaj yeem txhim kho tau zoo, thiab kev ua haujlwm ntawm cov hlau tuaj yeem txhim kho.
Kev siv ferrovanadium
1. Nws yog ib qho tseem ceeb alloy additive nyob rau hauv hlau thiab steel kev lag luam. Nws tuaj yeem txhim kho lub zog, toughness, ductility thiab kub tsis kam ntawm steel. Txij li thaum xyoo 1960, daim ntawv thov ntawm ferrovanadium hauv kev lag luam hlau thiab hlau tau nce ntau heev, rau xyoo 1988 suav txog 85% ntawm kev noj ferro vanadium. Kev faib ua feem ntawm cov hlau vanadium nyob rau hauv steel yog carbon steel 20%, siab zog tsawg alloy steel 25%, alloy steel 20%, cuab yeej steel 15%. Lub zog siab tsis tshua muaj hlau hlau (HSLA) uas muaj vanadium hlau yog dav siv hauv kev tsim thiab tsim cov roj / roj pipelines, cov tsev, Choj, rails, siab hlab ntsha, carriage thav duab thiab lwm yam vim nws lub zog siab.
2. Nyob rau hauv lub non-ferrous alloy feem ntau yog siv los tsim vanadium ferrotitanium alloy, xws li Ti-6Al-4V, Ti-6Al-6V-2Sn thiab
Ti-8Al-1V-Mo. Ti-6al-4v alloy yog siv rau hauv kev tsim cov dav hlau thiab foob pob hluav taws zoo heev cov khoom siv hluav taws xob kub, hauv Tebchaws Meskas yog qhov tseem ceeb heev, cov khoom tsim tawm ntawm titanium vanadium ferroalloy suav nrog ntau dua ib nrab. Ferro vanadium hlau kuj tseem siv tau rau hauv cov khoom sib nqus, cam khwb cia hlau, carbide, superconducting cov ntaub ntawv thiab cov ntaub ntawv nuclear reactor thiab lwm yam.
3. Feem ntau yog siv los ua alloy additive hauv steelmaking. Lub hardness, lub zog, hnav tsis kam thiab ductility ntawm steel
tuaj yeem txhim kho tau zoo los ntawm kev ntxiv ferrovanadium rau hauv cov hlau, thiab kev txiav cov hlau tuaj yeem txhim kho. Vanadium hlau feem ntau yog siv rau hauv kev tsim cov pa roj carbon steel, tsis tshua muaj alloy steel lub zog steel, siab alloy steel, cuab yeej steel thiab cam khwb cia hlau.
4. Haum rau alloy steel smelting, alloy element additive thiab stainless hlau electrode txheej, thiab lwm yam. Cov qauv no siv rau zus tau tej cov niobium pentoxide mloog zoo li raw khoom rau steel ua los yog casting additives, electrode raws li alloy tus neeg sawv cev, sib nqus cov ntaub ntawv thiab lwm yam kev siv. hlau vanadium.
