Qhov twg RP Qib Fits hauv Electrode Range
Lub 250mm RP (lub zog tsis tu ncua) graphite electrode yog tus nqi -qib taw qhia ntawm tus qauv ntau yam. Nws yog tsim los rau nruab nrab tam sim no- nqa lub peev xwm: hluav taws xob tiv taus siab dua hauv qib HP thiab UHP, yog li lub zog poob hauv cov electrode yog me ntsis ntau dua, tab sis txoj kev tsim khoom yooj yim dua thiab tus nqi ib tonne qis dua.
250 hli, ze rau 10 ntiv tes, yog tus qauv electrode txoj kab uas hla uas haum rau cov laus los yog me me hluav taws xob arc rauv thiab ntau yam ntawm submerged -arc smelting lub luag hauj lwm. Nominal lengths thiab xov geometry yog matched rau lub electrode kem ntawm lub cub tawg thiab pom zoo ua ntej ntau lawm.
Yam Khoom thiab Cov Qauv
Tsawg ntom ntom microstructurenrog tswj porosity, uas ua kom cov electrode nyob rau hauv rov qab thermal cycling.
Siab dua hluav taws xob resistivitydua li HP lossis UHP, tau txais kev pauv rau tus nqi qis dua ib tonne.
Tswj impurity theem- sulfur, tshauv thiab lwm yam khoom seem muaj nyob rau hauv qhov ib txwm muaj rau qib, nrog kev txwv dav dua li qib hwm.
Mechanical zoguas tseem tiv thaiv kev tawg thaum thauj, tuav thiab ua - ntawm kab.
Vim tias cov neeg tsim khoom kho qhov sib xyaw ua ke thiab lub voj voog graphitising sib txawv, tus nqi ntawm tus kheej raug nyeem los ntawm daim ntawv pov thawj ntawm ntau ntau es tsis yog los ntawm ib daim duab catalog.
Cov ntawv thov hauv EAF thiab Submerged -Arc Furnaces
Cov laus thiab me hluav taws xob arc rauv.Qhov twg lub transformer thiab lub hwj chim qhov kev pab cuam yog nruab nrab, RP qib muab kev ntseeg tau zoo yam tsis tau them nyiaj rau cov khoom lub cub tawg siv tsis tau, yog li nws tseem yog qhov kev xaiv pheej yig rau niaj hnub steelmaking.
Submerged -arc furnaces.Ferroalloy smelting, daj-phosphorus ntau lawm thiab corundum smelting tag nrho cia siab rau cov electrode raws li cov kab hluav taws xob uas nqa tam sim no mus rau hauv tus nqi. Cov electrode ua haujlwm tsis tu ncua tiv thaiv lub nra kub, thiab cov khoom siv dag zog thiab kev kwv yees hnav ntawm RP qib ua rau nws ua tau zoo rau cov haujlwm no.
Routine foundry lub luag haujlwm.Cov me me melting thiab tuav lub cub tawg uas ua haujlwm ntawm lub zog tsawg zog kuj tseem siv RP electrodes, vim tias qhov ntxiv conductivity ntawm HP lossis UHP qib yuav tsis rov qab los rau hauv qhov qis - fais fab kev pab cuam.
Qib sib piv ntawm ib nrais muag
| Qib | kwv tij tam sim no ceev | Hom kev siv |
|---|---|---|
| RP (lub zog tsis tu ncua) | qis | EAFs me me thiab laus dua, submerged -arc thiab smelting furnaces |
| HP (muaj zog heev) | Nruab nrab | Txheem EAF steelmaking thiab ladle refining |
| UHP (ultra{0}}hwj chim siab) | Siab dua | Loj loj - zog EAFs thiab hnyav loaded ladle furnaces |
Kev ntsuas tam sim no nyob ntawm txoj kab uas hla, qib thiab qhov cub ua haujlwm, yog li daim duab ua haujlwm tau teeb tsa tawm tsam cov ntaub ntawv ntawm cov electrode tshwj xeeb es tsis yog los ntawm lub npe qib ib leeg.
Qhov twg graphite electrodes tsis yog lus teb
Ob tsev neeg txheej txheem feem ntau tsis meej pem nrog graphite electrode noj. Thawj aluminium smelting siv prebaked carbon anodes uas tau noj nyob rau hauv lub electrolytic cell, tsis graphite electrodes. Copper smelting thiab refining siv sib txawv electrode thiab hauv ob sab phlu systems tag nrho. Ob leeg koom nrog rau lwm cov tsev neeg cov khoom, thiab kev kho cov graphite electrode raws li kev hloov pauv khoom siv rau lawv yog ib qho kev nkag siab tsis zoo uas tsim nyog tshem tawm thaum ntxov hauv kev sib tham.
Cov lus nug nquag
Q: RP txhais li cas hauv graphite electrodes?
Lub zog tsis tu ncua. Nws yog qib nrog qhov tsawg tshaj plaws tam sim no ceev ntawm tus qauv ntau yam, xaiv qhov twg tus nqi tswj tseem ceeb tshaj qhov siab tshaj plaws lub zog nkag.
Q: Dab tsi yog 250mm hauv nti?
250 hli yog kwv yees li 10 ntiv tes, uas yog vim li cas txoj kab uas hla feem ntau piav raws li 10 nti electrode nyob rau hauv cov ntaub ntawv qub rau cub tawg.
Q: Vim li cas RP electrode pheej yig dua li UHP electrode?
Txoj kev RP siv cov khoom siv qis dua - tus nqi raw khoom thiab lub voj voog ua haujlwm yooj yim dua, thiab qib nqa qis dua tam sim no, yog li qhov kev xav tau ntawm cov khoom siv me dua.
Q: Tus qauv twg npog graphite electrodes?
GB / T 3074 series npog cov qauv kev sim siv rau cov khoom tseem ceeb, thiab YB / T 4088 npog cov khoom lag luam; daim ntawv tam sim no ntawm txhua tus qauv siv.
Q: Puas tuaj yeem RP electrode hloov HP electrode?
Tsuas yog qhov kev pab cuam lub tshuab hluav taws xob tso cai rau nws. Hloov qib qis mus rau qib siab - lub luag haujlwm lub zog ua rau muaj kev noj tshwj xeeb thiab kev pheej hmoo ntawm kev tawg, yog li txhua qhov kev hloov pauv yuav tsum ua raws li lub tshuab hluav taws xob cov ntaub ntawv ua haujlwm.
Q: Puas yog graphite electrodes siv hauv aluminium smelting?
Tsis yog. Aluminium electrolysis siv prebaked carbon anodes, uas yog ib tsev neeg cov khoom sib txawv los ntawm graphite electrodes siv nyob rau hauv hluav taws xob arc thiab submerged -arc furnaces.
