98% V2O5 Vanadium Pentoxide Flake rau Steelmaking thiab Catalyst Applications

Vanadium Pentoxide Flake ntawm ib sab

Vanadium pentoxide flake yog fused crystalline daim ntawv ntawm V2O5 thiab yog ib qho ntawm cov khoom lag luam vanadium tshaj plaws hauv kev lag luam hlau thiab tshuaj lom neeg. Nws yog muab nyob rau hauv tsaus grey rau dub los yog xim av flakes nrog ib tug vitreous puas, thiab nws melts ntawm roughly 690 degree. Piv nrog rau cov hmoov sib faib zoo, daim ntawv flake ntws thiab tsub nqi ntau dua, uas tseem ceeb thaum tsuas yog ob peb kilograms ib lub tshav kub yuav tsum tau ntsuas kom raug.

Cov qib tau piav qhia ntawm no yog tsim los rau qhov tsawg kawg nkaus V2O5 cov ntsiab lus ntawm 98%. Cov ntsiab lus oxide siab txhais tau tias tsawg dua gangue thiab tsawg dua cov ntsiab lus rau txhua kilogram ntawm vanadium xa tawm, yog li tus nqi tseeb ntawm ib chav tsev ntawm vanadium nyob twj ywm kev sib tw txawm tias tus nqi tawm mus.

Cov xim ntawm cov flake sib txawv nrog cov keeb kwm txias thiab cov kab tsis huv, tab sis xim ib leeg tsis qhia qib. Cov neeg yuav khoom yuav tsum cia siab rau daim ntawv ntsuam xyuas ntau dua li ntawm qhov tshwm sim thaum tsim nyog ntau.

Muaj nuj nqi hauv Steelmaking thiab Alloy Production

Nyob rau hauv steelmaking, vanadium yog ntxiv rau grain refinement thiab nag lossis daus. Dissolved vanadium ua ke nrog cov pa roj carbon thiab nitrogen thaum lub sij hawm txias kom tsim cov V (C, N) hais tias pin lis ciam teb thiab nce yield zog yam tsis muaj ib tug loj poob ntawm toughness. Microalloyed structural steels ib txwm muaj txog 0.02-0.15% V, thaum cov cuab yeej steel, forging dies, rail steels thiab qee cov qib high-ceev tau ntau dua. Vanadium kuj txhim kho hardenability thiab tsis kam mus softening ntawm qhov kub thiab txias.

Feem ntau ntawm V2O5 noj los ntawm kev lag luam steel tsis raug them ncaj qha rau lub ladle. Nws yog thawj zaug txo rau ferrovanadium, feem ntau yog los ntawm aluminothermic cov tshuaj tiv thaiv nyob rau hauv uas txhuas hmoov txo cov oxide thiab cov resulting alloy xa mus rau cov hlau yaj. Ferrovanadium qib tau muab los ntawm kev siv dav dav xws li ASTM A102 thiab GB / T 4139 yog tsim los ntawm flake V2O5 ntawm hom tau piav qhia ntawm no. Vanadium-nitrogen alloys, uas muab kev rov qab zoo dua ntawm qhov qis dua vanadium ntxiv, kuj yog tsim los ntawm tib oxide feedstock.

Grain refinement:nplua carbonitride precipitates txwv austenite grain loj hlob thaum ua hauj lwm kub.

Lub zog nce:nag lossis daus ntxiv ntxiv 100-200 MPa rau cov qib microalloyed ntawm qib qis ntxiv.

Thaum tshav kub kub kuj:vanadium carbides tiv taus coarsening, yog li lub zog yog khaws cia ntawm qhov kub thiab txias.

Ntxuav melting:qib 98% flake qhia tsawg dua slag ntim thiab tsawg dua qhov seem qis dua -purity oxide.

Catalyst thiab Chemical Applications

Vanadium pentoxide yog lub sijhawm ua haujlwm hauv tsev neeg loj ntawm kev lag luam oxidation catalysts. Txhawb V2O5 catalysts oxidise sulfur dioxide rau sulfur trioxide hauv sulfuric acid nroj tsuag, hloov naphthalene los yog ortho-xylene rau phthalic anhydride, thiab pab tsim cov txiv neej anhydride thiab lwm yam intermediates. Vanadium-titanium oxide formulations kuj tau siv nyob rau hauv cov kev xaiv catalytic txo cov tshuab flue gas.

Tshaj li catalysis, cov oxide yog siv los ua cov xim hauv iav thiab ceramics, qhov twg nws tsim ntsuab, amber thiab grey tints nyob ntawm oxidation xeev, thiab ua ib qho nruab nrab rau cov tshuaj vanadium. Tom qab hloov dua siab tshiab rau vanadyl sulphate los yog lwm yam electrolyte ntsev, vanadium los ntawm siab -purity flake pub tag nrho -vanadium redox flow batteries rau daim phiaj- teev lub zog cia. Catalyst thiab roj teeb siv tsis kam ua rau impurities tsawg dua steelmaking, yog li cov ntsiab lus qis ntawm 98% qib yog qhov tseem ceeb.

Quality Control, Packing thiab Logistics

Txhua qhov ntau lawm yog kuaj thiab soj ntsuam rau V2O5, nrog rau kev txheeb xyuas ntawm cov dej noo, flake loj faib thiab pom qhov muag. Cov ntawv pov thawj soj ntsuam thiab ntau cov ntaub ntawv khaws tseg tau khaws cia kom qhov kev xa tuaj yeem rov qab mus rau nws qhov txo qis lossis leaching batch. Kev ntsuas qhov loj me yog tswj los ntawm kev tshuaj ntsuam, thiab qhov loj me lossis qhov qis qis yog sib cais ntau dua li sib xyaw rau hauv cov khoom xa tuaj.

Cov khoom ntim tau ntim rau hauv 250 kg steel nruas kom txwv tsis pub ya raws - thaum lub sijhawm thauj khoom hiav txwv thiab khaws cia. Drums yuav tsum tau kaw nyob rau hauv ib tug qhuav, ventilated warehouses, kom deb ntawm cov acids, txo cov neeg ua hauj lwm thiab cov organic plua plav, thiab yuav tsum tau nqa nrog tsim nyog tuav vim hais tias ntawm lub luj ntawm ib tug tag nrho nruas. Thaum cov oxide raug tuav hauv ntau, qhov tso pa tawm hauv zos thiab lub qhov ncauj qhov ntswg tau raug pom zoo, thiab cov dej nchuav yuav tsum tau muab tshem tawm sai sai thiab tsis txhob ntxuav rau hauv cov dej qhib.

Cov lus nug nquag

Q: Daim duab 98% hais txog dab tsi?
Nws yog qhov tsawg kawg nkaus vanadium pentoxide cov ntsiab lus ntawm flake. Qhov sib npaug feem ntau yog lwm yam vanadium oxides thiab cov impurities me, yog li cov vanadium tau xa tuaj rau ib tonne yog qhov siab tsis tu ncua.

Q: Lub flake puas tuaj yeem raug them ncaj qha rau lub ladle steel?
Kev them nyiaj ncaj qha yog ua tau nyob rau hauv qee qhov kev coj ua slag, tab sis feem ntau cov kws tsim steel siv V2O5 los ua ferrovanadium los yog vanadium-nitrogen alloy ua ntej, vim tias kev rov qab tuaj yeem kwv yees ntau dua li ntawd.

Q: Vim li cas cov xim txawv ntawm ntau ntau?
Txias tus nqi thiab kab impurities hloov qhov ntxoov ntxoo ntawm dub, xim av thiab grey. Xim tsis yog qhov ntsuas qib; tus nqi ntsuas tswj kev lees paub.

Q: Dab tsi flake loj yog ib txwm muab?
Txheem ntau lawm yog 20-80 hli nyob rau hauv dav thiab 2-8 hli nyob rau hauv thickness. Lwm qhov loj me tuaj yeem npaj tau yog tias tus txheej txheem xav tau kev txiav nqaim.

Q: Yuav tsum khaws cov khoom li cas?
Khaws cia rau hauv lub nruas kaw hauv qhov chaw qhuav, qhov cua kom deb ntawm cov kua qaub thiab txo cov neeg ua haujlwm. Cov dej noo khaws- thiab tiv tauj nrog cov khoom siv organic yuav tsum zam.

Q: Puas yog tib qib siv rau catalysts thiab roj teeb?
Catalyst thiab electrolyte cov neeg siv feem ntau yuav tsum nruj dua cov kev txwv ntawm hlau, silicon thiab lwm yam residuals tshaj steelmaking, yog li cov ntawv thov yuav tsum paub meej tias cov impurity profile ua ntej xaj.
