Dab tsi yog 250mm HP Graphite Electrode yog
Lub 250 hli HP (siab zog) graphite electrode yog ib tug nominal - txoj kab uas hla electrode qib tsim rau hluav taws xob arc furnaces (EAFs) thiab ladle furnaces uas ua hauj lwm ntawm ib tug ntau dua tam sim no ceev tshaj li niaj zaus zog (RP) xyaum tso cai. HP electrodes yog tsim los ntawm cov koob xaiv -coke-raws li raw cov ntaub ntawv, tsim ntawm siab dua thiab graphitised nyob rau hauv ib tug tswj thermal voj voog, uas txo cov hluav taws xob resistivity thiab nce txhua yam muaj zog.
Vim tias txoj kab uas hla 250 hli zaum ntawm qhov me me - mus rau - nruab nrab ntawm qhov kawg ntawm cov qauv, nws yog dav siv hauv cov khw muag khoom EAF, hauv cov chaw kho tsheb ladle thiab hauv cov chaw tsim khoom uas qhov ntsuas kub loj thiab qhov ntsuas hluav taws xob yog nruab nrab. Nominal ntev ntawm 1600 mm, 1800 mm thiab 2200 mm npog feem ntau ntawm cov cub tawg, thiab lwm qhov ntev yog tsim rau kev kos duab.
Cov yam ntxwv tseem ceeb ntawm HP Qib
Plaub tus yam ntxwv piav qhia feem ntau ntawm qhov sib txawv ntawm HP thiab RP electrodes ntawm tib txoj kab uas hla:
Tsawg hluav taws xob resistivity- Kev hloov pauv tam sim no ua tau zoo dua, kev tso cai tam sim no ntau dua thiab qis dua kev noj ib tonne ntawm cov hlau.
Dense, uniform qauv- tswj porosity thiab ruaj khov bulk ceev txhim kho thermal conductivity thiab qeeb sab -phab ntsa oxidation.
Tswj impurity theem- sulfur, tshauv thiab lwm yam khoom seem yog tuav kom nruj kom cov electrode ntxiv tsis xav tau cov ntsiab lus rau yaj.
Mechanical thiab thermal shock kuj- txhim kho lub zog flexural thiab thermal stability txo qhov kev pheej hmoo ntawm kev tawg thaum lub sijhawm them nyiaj, hloov hluav taws xob thiab lub zog viav vias.
Cov ntaub ntawv nyiaj txiag rau HP qib tshaj RP zoo li lub zog luv dua- raws sijhawm, tsawg dua electrode- cuam tshuam txog kev nres thiab txo qis qis ntawm qhov kawg ntawm kev sib tw.
Hom Specifications ntawm 250mm HP Electrode
Cov lus hauv qab no teev cov txiaj ntsig zoo rau qib no thiab txoj kab uas hla. Cov txiaj ntsig tiag yog ntsuas ntawm daim ntawv pov thawj ntawm txhua qhov ntau lawm thiab hloov me ntsis nrog cov khoom siv raw thiab graphitising txoj kev.

Threads raug txiav raws li cov txiv mis tapered matched rau lub qhov (socket profile) ntawm electrode. Ib qho 250 hli electrode yog ib txwm muab nrog 3 TPI lossis 4 TPI taper, thiab lub txiv mis txoj kab uas hla thiab xov ntev tau teev nyob rau ntawm tus neeg muag khoom kos duab kom cov kev sib koom tes tuaj yeem kuaj xyuas cov kab hluav taws xob.
Cov ntawv thov hauv EAF thiab Ladle Furnace Operation
Electric arc rauv steelmaking.Lub 250mm HP electrode yog siv rau cov khoom seem melting, carbon steel thiab alloy steel heats thiab tshwj xeeb steel qib nyob rau hauv me me thiab nruab nrab furnaces. Nws qhov kev tiv thaiv qis qis ua rau lub arc ruaj khov ntawm cov tswv yim muaj zog, uas ua rau luv yaj- nyob rau hauv lub sijhawm.
Ladle rauv refining.Nyob rau hauv theem nrab metallurgy lub electrode muab lub arc uas tuav lub da dej ntawm qhov kub thiab txias thaum lub sij hawm alloying thiab desulfurisation. Kev coj cwj pwm ruaj khov thiab tsis tshua muaj kev puas tsuaj tseem ceeb ntawm no ntau dua qhov siab tshaj plaws tam sim no, thiab qib HP suav nrog ob qho kev xav tau.
Foundries thiab ferroalloy units.Hlau casting, hlau recycling thiab ib co ferroalloy lub luag hauj lwm kuj siv 250 hli HP electrodes qhov twg lub hwj chim qhov kev pab cuam yog hnyav dua ib tug dawb RP lub luag hauj lwm.
Cov ntaub ntawv xaiv thiab xaj
Kev nug ua haujlwm tau rau 250mm HP electrodes muaj cov ntaub ntawv hauv qab no:
Qib thiab nominal txoj kab uas hla, ntxiv rau tag nrho ntev los yog qhov ntev phua yuav tsum tau los ntawm cov electrode kem.
Lub txiv mis hom, taper, xov suab thiab sib koom geometry, los yog tus lej kos duab.
Kom muaj nuj nqis rau thawj qhov kev txiav txim thiab qhov xav tau txhua xyoo ntim, yog li kev tsim khoom tuaj yeem teem sijhawm.
Qhov chaw nres nkoj qhov chaw, qhov rai xa khoom thiab kev ntim khoom xav tau.
Ib qho kev sim ntxiv tau thov dhau qhov kev tiv thaiv niaj hnub, qhov ntom ntom, lub zog, tshauv thiab thermal expansion ntsuas.
Kev qhia txog qhov sib koom ua ke thiab qhov ntev sib cais kom tsis txhob muaj cov kab tsis sib xws, uas yog ib qho ua rau kev sib koom ua haujlwm tsis ua haujlwm.
Packing, Cia thiab tuav
Export packing rau graphite electrodes combines nruj kev them nyiaj yug nrog kev tiv thaiv ntawm threaded xaus. Ntoo rooj plaub los yog pallets nqa lub cev electrode, threaded caps tiv thaiv lub qhov (socket), thiab ya raws -kab thaiv wrapping ua rau saum npoo qhuav thaum lub sij hawm thauj hiav txwv. Electrodes yuav tsum muab cia rau ntawm qhuav, theem racks thiab nqa nrog slings nyob ib ncig ntawm lub cev es tsis yog los ntawm lub qhov (socket). Lub ntsej muag sib koom yuav tsum tau muab ntxuav thiab lub txiv mis torqued rau daim duab muab rau ntawm tus neeg muag khoom kos duab ua ntej cov electrode txo qis rau hauv qhov cub.
Cov lus nug nquag
Q: HP txhais li cas hauv graphite electrode?
HP sawv rau siab zog. Nws yog qib nruab nrab ntawm cov qauv ntau, nyob nruab nrab ntawm lub zog tsis tu ncua (RP) thiab ultra- lub zog siab (UHP), thiab raug xaiv thaum lub cub tawg xav tau qhov ceev tam sim no ntau dua li RP xyaum ua.
Q: 250mm HP electrode txawv li cas ntawm 250mm RP electrode?
Ob leeg sib koom tib lub nominal txoj kab uas hla, tab sis qib HP muaj qis hluav taws xob resistivity, siab flexural zog thiab ib tug denser qauv, yog li nws zam ntau tam sim no thiab noj tsawg dua cov khoom ib tonne ntawm steel.
Q: Cov qauv twg siv rau graphite electrodes?
GB / T 3074 series npog cov kev sim rau kev tiv thaiv, flexural zog thiab cov khoom muaj feem xyuam, thaum YB / T 4088 npog cov khoom siv hluav taws xob graphite nrog nws qhov loj me thiab cov kev xav tau zoo.
Q: Ntev npaum li cas muaj rau 250 hli electrode?
1600 mm, 1800 mm thiab 2200 mm yog cov nominal lengths li ib txwm, thiab lwm yam ntev los yog ntev ua ke yog tsim los rau kos rau ib tug tshwj xeeb electrode kem.
Q: Vim li cas electrodes tawg ntawm qhov sib koom?
Kev sib koom ua tsis tau zoo feem ntau ua raws li qhov tsis sib haum xeeb taper geometry, tsis txaus lub zog thaum ua- nce, lossis kev puas tsuaj rau lub qhov (socket) thaum thauj thiab tuav es tsis yog qhov txhaum ntawm lub cev electrode nws tus kheej.
Q: Yuav tsum khaws cov electrodes ua ntej siv?
Khaws lawv rau ntawm qhov qhuav, theem racks kom deb ntawm cov plua plav thiab noo noo, tiv thaiv cov xov xaus nrog lub kaus mom, thiab tsis txhob muab tso rau hauv lub qhov (socket).
