Ferrovanadium hauv steelmaking

Ferrovanadium yog ib qho tseem ceeb ferroalloloy tsim ntawm Vanadium thiab hlau, feem ntau muaj 35% mus rau 85% Vanadium. Raws li kev tsis tseem ceeb ntxiv hauv kev lag luam steel qub, ferrovanadium cov khoom nyob hauv kev txhim kho cov khoom siv me me, ua kom zoo dua nws cov microstructure, thiab txhim kho nws cov kev ua tau zoo tag nrho.

Raws li lub ntiaj teb steel kev lag luam tau txav mus rau kev ua tau zoo, kev txuag hluav taws xob, thiab kev siv hluav taws xob ib puag ncig, ua ib puag ncig ntawm Ferrovanadium tau dhau los ua ntau dua thiab tseem ceeb.

Ferrovanadium raws li ib qho kev sib ntxiv ntxiv hauv kev sib ntxiv ntawm steelmaking

1. Mechanism ntawm Ferrovanadium qhov kev txiav txim hauv steelmaking

Thaum ntxiv rau Molten Steel ua ib tug neeg sawv cev ua ke, ferrovanadium sai dissolves thiab tso tawm vatadium. Vanadium thawj qhov teebmeem hauv cov hlau muaj raws li hauv qab no:

Cov kws ua kom zoo: Vanadium reacts nrog carbon thiab nitrogen los tsim cov carrersed carbonitrides (VC, VN, thiab V (C, N)). Thaum lub sijhawm kho tshav kub thiab dov, cov kaujses dispersed ho rov qab hais cov nplej. Cov kws sau qoob loo txhim kho lub zog thiab tawv ntawm cov hlau thaum tswj hwm kev ua kom zoo.

Txhim kho lub zog: Vanadium precipitates feem ntau hauv cov hlau li carbonitrides muaj zog, nce propce zog zog thiab tensile lub zog ntawm cov hlau. Qhov kev siv zog no ntxiv tau yog hais tshwj xeeb hauv cov khoom siv hlau tsis muaj zog, cov hlau hluav taws xob kom zoo.

Txhim kho Weldability: piv rau qee cov ntsiab lus carbide-tsim (xws li molybide-forming txhim kho cov khoom siv hlau qis dua thaum muaj kev cuam tshuam tsawg rau Weldability. Yog li ntawd, Ferrovanadium yog dav siv nyob rau hauv welded qauv qauv hlau.

Txhim kho cov hnav thiab cuam tshuam tiv thaiv: Vanadium tsub kom lub hardness thiab hnav tsis kam ntawm cov hlau thaum tswj hwm kev cuam tshuam zoo ntawm qhov kub kub. Qhov no ua kom ntseeg tau tias Vanadium-muaj cov hlau muaj lub neej kev pabcuam ntev dua nyob rau hauv kev ua haujlwm hnyav.

2. Kev thov ntawm Ferrovanadium hauv ntau cov qib steel

Ferrovanadiumyog siv nyob rau hauv ntau thaj chaw ntawm kev lag luam hlau, nrog kev sib txawv ntawm cov qauv steel, nrog cov kev sib txawv ntawm cov hlau sib txawv ntawm Ferrovanadium raws lawv cov kev xav tau tshwj xeeb.

Siv Qauv Hlau

Ntawm cov qauv tsim qauv, ferrovanadium yog feem ntau siv nyob rau hauv kev tsim cov high-zog rebars xws li HRB400 thiab HRB500 thiab HRB500 thiab HRB500. Thaum lub sij hawm kub yob cov txheej txheem, vanadium cov ntaub ntawv cov tshuaj carbonitrides, nce lub zog ntawm cov hlau tuav los ntawm 15% txog 30%. Qhov no txo ​​cov hlau uas yuav tsum tau ua thiab lowers tag nrho cov nqi ntawm cov phiaj xwm kev tsim qauv.

Pipeline Hlau Thiab Siab Hlab Hlau Hlau

Pipeline Hlau yuav tsum muaj lub zog siab thiab cov khoom muaj qis qis heev-kub. Qhov kev sib ntxiv ntawm ferrovanadium zoo txhim kho cov hlau cov txheej txheem kev hnav khaub ncaws thiab txhim kho nws qhov kev ua haujlwm qis dua, kom muaj kev nyab xeeb ntawm cov roj thiab roj pipelines nyob rau hauv ib puag ncig txias lossis muaj txiaj ntsig.

Automotive Thiab Machinery Steel

Ferrovanadium yog dav siv hauv cov hlau hlau, tshwj xeeb hauv cov thav duab tseem ceeb xws li thav duab, cov log tsheb, thiab kev ncua. Vanadium-muaj cov hlau uas muaj lub zog muaj zog zoo thiab hnav tsis kam, ua rau lub teeb yuag. Hauv kev tsim khoom machinery tsim, vanadium alloy muaj feem ntau siv los tsim cov zog zog, bearings, thiab txuas ntxiv lawv lub neej thiab kev ntseeg tau.

Hnav-resistant steel thiab high-splec steel hlau

Thaum ferrovanadium yog siv nyob rau hauv high-ceev steel, vanadium ntau txhim kho cov hlau xwm txheej theem nrab hardening muaj peev xwm thiab hnav tsis kam. Kev ceev cov cuab yeej siv cov hlau ceev tuaj yeem muaj txog li 1% mus rau 5% vanadium, ua kom cov khoom txiav thiab cov pwm kom muaj kev tiv thaiv siab thiab hnav tsis kam kub.

Tus Hlau Stainless Thiab Kub-Resistant Steel
Lub xub ntiag ntawm vanadium hauv stainless hlau thiab kub-resistant steel txhim kho kev ua kom kub, ua rau cov roj kub kub, thiab cov hlab cua kub siab.

3. Kev khwv nyiaj txiag thiab cov txheej txheem ntawm ferrovanadium

Txuag cov nqi alloy: muab piv rau cov khoom siv alloy xws li molybdenum thiab niobium, vanadium, ua rau muaj txiaj ntsig zoo ntawm cov hlau thaum sib tham kom ua tau zoo.

Txo cov khoom siv hlau: ntxiv rau ntawm Ferrovanadium nce cov roj ntsha hauv cov dej num hauv cov dej num, txo cov nqi kev txuag hluav taws xob thiab emission txo cov cai.

Txhim Kho Cov Khoom Sib Tsoo: Kev Tsim Kho Cov Hlau yog siv dav hlau siv, thiab tshuab tsav tsheb hlau ua haujlwm ntxiv kom ntxiv tus nqi thiab cov nqi sib tw.

4. Kev loj hlob ntawm ferrovanadium hauv steelmaking

Nrog rau kev cog lus xav kom muaj zog thiab kev ua tau zoo ntawm cov hlau, cov ntawv thov ua ntu zus ntawm Ferrovanadium yog feem ntau hauv cov chaw hauv qab no:

Kev loj hlob sai ntawm tsawg-alloy lub zog-zog hlau: nrog kev nce qib qis rau cov kev lag luam hauv ntiaj teb rau kev ua lag luam rau ferrovanadium yog muaj zog.

Green Metallurgy thiab kev txuag hluav taws xob thiab emission txo qis: ntxiv rau kev siv hlau ua kom txo qis ntawm cov hlau me me ntawm cov ntsuab metallurgy.

Cov ntaub ntawv nthuav dav: dhau kev siv thiab cov tshuab, Ferrovanadium tseem pom nce ntxiv siv cov cuab yeej siv hluav taws xob tshiab, cov cuab yeej petrochemical, thiab cov tub rog.

Raws li tus yuam sij ferrroalloy, Ferrovanadium plays ib txoj haujlwm tsis txaus ntseeg hauv kev siv hlau loj hauv kev sib tsoo. Los ntawm kev ua kom zoo dua cov nplej loj, txhim kho kev ua kom muaj zog, thiab txhim kho wenerabilium, ferrovanadium ntau thiaj li ua tau tag nrho cov hlau. Raws li kev lag luam hlau txav mus rau kev ua haujlwm siab thiab muaj kev txhim kho kom ruaj khov, ferrovanadium cov ntawv thov yuav nthuav dav thiab nws tus nqi yuav txuas ntxiv mus ntxiv. Nyob rau yav tom ntej, ferrovanadium yuav tsis tsuas yog ib qho kev lag luam steel tab sis tseem yuav ua qhov tseem ceeb hauv kev tsav tsheb txhim kho ntawm lub ntiaj teb kev lag luam tshiab kev lag luam.
