Ferrovanadium Qib FeV50 thiab FeV80: Specification thiab Verification
Tso lus
Ferrovanadium Qib thiab Tus lej txhais li cas
Ferrovanadium yog yuav ntawm vanadium cov ntsiab lus, tsis nyob ntawm qhov hnyav. FeV50 thiab FeV80 yog ob qib uas suav rau feem ntau hla - kev lag luam ciam teb; tus naj npawb yog qhov nominal vanadium feem pua, yog li ib tonne ntawm FeV80 xa roughly 1.6 npaug ntawm vanadium ntawm ib tonne ntawm FeV50. Qhov kev xaiv ntawm lawv yog tus lej lej: qib siab dua txo cov khoom thauj, ntim thiab tuav tus nqi ib chav tsev ntawm vanadium, thaum qib qis muab cov kauj ruam me me thaum txiav cov cua sov thiab txo qhov kev pheej hmoo ntawm overshooting lub qhov rais nqaim.
| Yam khoom | FeV 50 | fwv 80 |
|---|---|---|
| Nominal vanadium cov ntsiab lus | 50% | 80% |
| Standard loj feem | 10-50 hli | 10-50 mm los yog 10-100 mm |
| Kev ntim khoom | 250 kg steel nruas | 250 kg nruas los yog 1 t lub hnab loj |
| Standard siv | ASTM A102/A102M | ASTM A102/A102M |
| Haum ntxiv point | Ladle trim | Hloov los yog cub hluav taws xob them, bulk alloying |
Complementary lub teb chaws specifications muaj, suav nrog GB / T 4139 rau vanadium ferroalloys hauv Suav lag luam. Qhov twg ib qhov project sib xyaw cov neeg xa khoom txawv teb chaws thiab txawv teb chaws, daim ntawv xaj yuav tsum tau hais txog qhov kev tshuaj ntsuam txwv tsis pub muaj kev cia siab rau qhov kev xaiv qib ib leeg.
Chemical thiab Physical Verification
Kev txiav txim ntawm vanadium ferroalloy yuav tsum txhim kho cov kev txwv rau vanadium, carbon, silicon, aluminium, phosphorus thiab sulfur, thiab hais txog cov qauv thiab kev tshuaj ntsuam. Qhov feem ntau tsis ua hauj lwm hauv kev soj ntsuam tuaj tsis yog qib tsis raug tab sis tus qauv tsis raug: ferroalloys cais tsis zoo, yog li kev ntsuas los ntawm sab saum toj ntawm lub nruas tuaj yeem ua rau qhov tshwm sim ob peb feem kaum ntawm ib feem ntawm qhov nruab nrab ntawm qhov cua sov. Laum lossis tsoo cov qauv ntawm tag nrho tus ntoo khaub lig-section, ua raws cov kauj ruam txo cov ntaub ntawv, muab cov txiaj ntsig uas tuaj yeem tiv thaiv. Density and lump size distribution are also worth measuring, because a high proportion of fines changes the dissolution behaviour in the ladle and reduces recovery.
Loj Fractions, Ntim thiab Logistics
Lub pob loj yog qhov kev txiav txim siab. Ib qho 10-50 hli feem yaj sai sai thiab haum rau lub ladle ntxiv; 10-100 mm yog siv qhov twg cov hlau yog them ntxov thiab muaj sij hawm rau yaj. Txheem ntim yog 250 kg steel nruas, nrog ib lub hnab loj loj muab rau cov qib siab dua qhov kev tuav tus nqi tseem ceeb. Ferrovanadium raug cais raws li HS nqe lus 7202.92, thiab cov ntaub ntawv xa tawm yuav tsum nqa cov ntsiab lus ntawm vanadium ntawm cov khoom xa tuaj vim tias lub luag haujlwm thiab tus nqi raug suav nrog cov vanadium, tsis yog qhov hnyav tag nrho. Kev tiv thaiv cov dej noo: cov nruas yuav tsum tau muab khi los yog kaw, thiab lub thawv yuav tsum tau tso cua thaum lub sij hawm thauj mus los hauv hiav txwv kom tsis txhob muaj qhov sib xyaw ntawm cov khoom sib xyaw.
Tus nqi tsim thiab ua lag luam teeb liab
Ferrovanadium yog luv nqi ib kilogram los yog ib phaus ntawm muaj vanadium, thiab cov ntawv luam tawm nyob rau hauv cov teb chaws Europe, lub tebchaws United States thiab Tuam Tshoj yog tag nrho cov normalized rau lub hauv paus, uas yog vim li cas tib alloy tuaj yeem tshwm sim li ob tus lej sib txawv ntawm ib tonne ntawm cov khoom. Lub ntsiab inputs rau tus nqi yog vanadium pentoxide thiab vanadium -cov kabmob slag muaj, hluav taws xob nqi ntawm lub smelting theem, steel zeb xav tau los ntawm rebar thiab seem producers, thiab theem ntawm Suav export muaj. Tus neeg yuav khoom uas taug qab V2O5 cov lus hais thiab rebar tso tawm ua ke yuav nyeem ferrovanadium kev lag luam ntau dua li tus uas saib ferrovanadium ib leeg.
Cov ntaub ntawv thiab Kev Tswj Xyuas Zoo
Kev xa khoom tiav yuav tsum tau nrog rau daim ntawv pov thawj ntawm kev tshuaj xyuas, ib daim ntawv teev cov khoom ntim uas sau lub nruas lossis lub hnab ntim khoom, thiab, yog tias xav tau, daim ntawv pov thawj thib peb ntawm kev tshuaj ntsuam xyuas tau muab tso rau ntawm qhov chaw thau khoom. Cov kev tswj tau zoo tshaj plaws yog cov txheej txheem sau cia ua ke nrog kev tshawb xyuas sai ntawm vanadium cov ntsiab lus thiab pob loj; Cov txiaj ntsig kev tsis sib haum xeeb yog yooj yim dua los daws tau thaum cov qauv khaws cia yog traceable rau ib lub nruas tshwj xeeb. Khaws cov qauv los ntawm txhua qhov ntau rau lub sijhawm teev tseg kom qhov kev tshawb xyuas metallurgical tom qab tuaj yeem taug qab rov qab mus rau cov khoom siv.
Cov lus nug nquag
Q:Puas yog FeV80 ib txwm pheej yig dua ib chav tsev ntawm vanadium?
A: Feem ntau cov nqi thauj khoom thiab tuav ib kilogram ntawm cov vanadium muaj qis dua nrog FeV80, tab sis qhov sib txawv nqaim thaum lub lag luam hwm rau qib siab dua yog dav. Sib piv tus nqi ib kilogram ntawm muaj vanadium, tsis raug nqi ib tonne ntawm alloy.
Q:Cov kev txwv twg yuav tsum tau sau rau hauv daim ntawv xaj khoom?
A: Vanadium, carbon, silicon, aluminium, phosphorus thiab sulphur, ua ke nrog cov feem me me, kev kam rau siab ntawm cov pob loj, hom ntim thiab cov qauv thiab kev tshuaj xyuas yuav siv tau thaum muaj kev sib cav.
Q:Yuav ua li cas yuav tsum tau coj mus kuaj?
A: Siv qhov nce ntxiv los ntawm tag nrho tus ntoo khaub lig- ntu ntawm ob peb lub nruas, sib xyaw thiab txo lawv mus rau ib qho qauv kuaj, thiab sau cov naj npawb nruas siv. Sampling tsuas yog saum npoo ntawm ib lub pob tsis yog tus sawv cev.
Q:Cov pob loj puas cuam tshuam rov qab?
A: Yog. Cov khoom zoo oxidises thiab tshaj tawm rau slag yooj yim dua, thiab cov pob coarse heev yuav tsis yaj tag nrho ua ntej tapping. Sib piv qhov loj me me rau qhov sib ntxiv yog qhov yooj yim tshaj plaws los tiv thaiv kev rov qab los.
Q:Dab tsi txiav txim siab qhov kev faib tawm?
A: Ferrovanadium poob rau hauv HS nqe lus 7202.92. Tus nqi tshaj tawm thiab cov dej num siv tau ua raws li cov vanadium muaj nyob rau hauv cov khoom xa tuaj, yog li daim ntawv pov thawj ntawm kev tshuaj xyuas thiab daim ntawv xa nyiaj yuav tsum pom zoo rau cov ntsiab lus vanadium.
