Yuav Ua Li Cas Graphite Nqe Quoted hauv Kev Xyaum
Tsis muaj ib tus nqi hauv ntiaj teb rau graphite. Dab tsi yog kev lag luam yog tsev neeg ntawm cov khoom lag luam nrog cov nqi sib txawv: graphite electrode los ntawm txoj kab uas hla thiab lub zog hluav taws xob, siab -graphite- carbon electrode, graphite block thiab graphite hmoov, ntxiv rau ntuj flake graphite los ntawm cov ntsiab lus carbon thiab mesh loj. Electrode yog hais txog ib tonne, feem ntau yog ex- ua haujlwm lossis FOB, nrog rau txoj kab uas hla, chav kawm fais fab, qib txiv mis thiab cov ntim khoom sib cais. Flake graphite concentrates tau hais ib tonne los ntawm qib carbon (piv txwv li 94, 95, 97 feem pua carbon) thiab los ntawm flake loj, thiab cov qib zoo ua lag luam ntawm luv nqi rau cov flake loj vim tias lawv ua haujlwm sib txawv.
Daim Ntawv Qhia Tus Nqi Theem rau Graphite Electrode hauv Suav teb
Cov lus hauv qab no tau pom cov lus hais nyob rau hauv Suav teb kev lag luam nyob rau lub Xya hli ntuj 30, hauv yuan ib tonne. Lawv yog cov qib siv rau kev taw qhia, tsis yog kev muab; qhov dav ntawm txhua qhov qhia txog qhov sib txawv hauv chav kawm fais fab, qib txiv mis, nqe lus them nqi thiab kev xa khoom nrug.
| Khoom | Nominal txoj kab uas hla | Tus nqi siv, yuan / tonne |
|---|---|---|
| Graphite electrode | 9 60mm | 11,000 – 11,500 |
| Graphite electrode | 1020 hli | 11,500 txog 12,000 |
| Graphite electrode | 1 272mm | 12.000-13.500 Nws |
| High graphite carbon electrode | 9 60mm | 6,300 txog 6,500 |
| High graphite carbon electrode | 1020 hli | 6,500 txog 7,000 |
| High graphite carbon electrode | 1 272mm | 7,300 txog 7,500 |
Ob tug qauv yog pom nyob rau hauv cov ntaub ntawv. Tus nqi nce nrog txoj kab uas hla nyob rau hauv txhua tsev neeg cov khoom, vim hais tias tus ntoo khaub lig loj dua -section xav tau ib tug loj xovxwm, ntev graphitization lub sij hawm thiab ntau machining. Qhov sib txawv ntawm ob tsev neeg yog qhov dav thiab kwv yees qhov sib npaug, uas qhia tau tias qhov sib txawv tsis yog qhov loj me xwb: siab -graphite- carbon electrode siv cov khoom sib txawv thiab qib graphitization qis, yog li nws ua haujlwm qis dua tam sim no.
Tus nqi tsav tsheb: Coke, Pitch thiab hluav taws xob
Cov khoom siv raw yog cov khoom loj tshaj plaws ntawm cov nqi hluav taws xob electrode. Koob coke thiab binder pitch ua ke tus account rau ntau tshaj ib nrab ntawm tus nqi ntawm ib tug tiav tonne nyob rau hauv ib txwm ua lag luam, yog li electrode nqi lem coke muaj nrog ib tug lag ntawm ib mus rau ob peb lub hlis twg. Hluav taws xob yog qhov tseem ceeb thib ob, vim tias graphitization siv ntau txhiab kilowatt -teev ib tonne, uas txhais tau hais tias cov nqi hluav taws xob hauv cheeb tsam thiab kev thauj khoom -txoj cai txav cov nqi hauv zos txawm tias coke tsis hloov pauv. Thib peb los hloov dua siab tshiab nqi - sib sau, ci, impregnation, machining thiab graphite poob raws li turnings - thiab cov no kuj ruaj khov thiab scale nrog cov nroj tsuag siv.
Vim li cas Electrode thiab Natural Graphite tsis txav mus ua ke
Ntuj flake graphite thiab hluavtaws graphite electrode yog cov lag luam sib cais koom ua ke ntawm cov khoom nyoos - cov khoom kawg. Flake graphite tus nqi teb rau cov khoom xav tau, cov qib mining thiab kev thov los ntawm cov khoom siv hluav taws xob, cov roj nplua nyeem thiab roj teeb anode feedstock. Electrode nqi teb rau hluav taws xob hlau tso zis, UHP qib thov thiab coke mov. Rau lub tshuab steel, tsuas yog cov saw hlau electrode cuam tshuam rau kev siv nyiaj txiag; rau ib tug tub luam, ob chains yuav tsum tau taug qab sib cais es tsis yog ib tug graphite lag luam.
Nyeem ib nqe lus kom raug
Before price comparison, six items must be fixed on both sides: diameter and power class, nipple grade and quantity supplied, measured values for resistivity, bulk density, flexural strength and ash, packing type and joint protection, Incoterm and port, and payment terms. Ib qho kev hais tawm uas tshem tawm cov chav fais fab tsis sib piv, vim tias tus qauv - lub zog kem thiab ib qho ultra- siab - lub zog kab ntawm tib txoj kab uas hla sib txawv ntawm cov nqi thiab kev siv. Nws tseem tsim nyog sau cov hnub siv ntawm ib daim ntawv teev nqi, vim tias cov lus hais electrode feem ntau siv tau rau lub sijhawm luv xwb.
Cov lus nug nquag
Q:Vim li cas tus nqi sib txawv thiaj li dav rau ib txoj kab uas hla?
A: Vim hais tias chav kawm fais fab, qib txiv mis, cov hmoov tshauv thiab kev tiv thaiv sib txawv ntawm cov neeg muag khoom, thiab vim tias cov nqe lus xa khoom, cov nqe lus them nqi thiab ntim khoom feem ntau qhib rau thawj cov lus. Txhim kho tag nrho rau qhov kev sib piv rau qhov nqaim qhov ntau.
Q:Puas pheej yig dua electrode txo tus nqi tag nrho?
A: Tsis tas li. Kev siv yog ntsuas hauv kg ib tonne ntawm cov hlau, yog li kaum feem pua tus nqi qis dua yuav raug tshem tawm los ntawm kaum feem pua siab dua tus nqi noj lossis los ntawm kev tawg ntau dua rau ib qho cua sov.
Q:Ntau npaum li cas cov qib kev siv no tau hloov kho?
A: Cov khoom siv hluav taws xob hauv tsev hauv Suav teb feem ntau yog luam tawm nyob rau ib lim tiam lossis ib nrab-ib hlis, thaum cov ntawv xa tawm tau rov siv tau rau txhua qhov kev nug vim tias coke thiab thauj khoom txav nrawm dua li cov npe tshaj tawm.
Q:Puas yog siab graphite carbon electrode hloov rau UHP electrode?
A: Rau cov dej num tam sim no tsawg nws tuaj yeem ua tau, thiab nws raug nqi tsawg dua ib tonne. Nws yuav tsum tsis txhob siv qhov twg transformer fais fab thiab qhov ceev tam sim no yuav tsum tau UHP qib, vim hais tias lub ntsis yaig thiab tawg yuav nce sharply.
Q:Cov ntaub ntawv dab tsi uas ib txwm xav tau kom tau txais cov lus hais ruaj khov?
A: Txoj kab uas hla, chav kawm fais fab, kom muaj nuj nqis, qib txiv mis thiab qhov loj me, qhov chaw nres nkoj lossis chaw xa khoom, qhov yuav tsum tau ntim khoom, thiab cov nqi tshwj xeeb xav tau ntawm daim ntawv pov thawj ntawm kev tshuaj xyuas.
Q:Tus nqi txuas nrog rau lub sijhawm ua haujlwm li cas?
A: Cov txheej txheem diameters hauv cov qib feem ntau yog muaj los ntawm cov khoom lag luam, thaum cov kab loj loj thiab cov txiv mis tshwj xeeb yuav tsum muaj lub voj voog ntau lawm, yog li lub sij hawm txhuas thiab tus nqi yuav tsum tau lees paub ua ke es tsis yog cais.
