Lub hom phiaj ntawm Graphite Electrodes hauv Steelmaking & Metallurgy
Nkag siab lub hom phiaj thiab qhov tseem ceeb ntawm graphite electrodes
- Core Function:Ua hluav taws xob thiab hloov mus rau hauv thermal zog (arc tshav kub).
- Qib:Muab faib ua RP, HP, thiab UHP raws li lub peev xwm nqa tam sim no.
- Durability:Muaj peev xwm tiv taus qhov kub thiab txias txog li 3,000℃thaum tswj kev tiv thaiv qis.
- Qauv:Ua raws li IEC 60239 thiab GB / T 3072 specifications.
1. Lub Hom Phiaj Core: Kev hloov pauv hluav taws xob hauv metallurgy
Graphite electrodes ua "lub plawv" ntawm Electric Arc Rauv (EAF) steelmaking txheej txheem. Lawv lub hom phiaj tseem ceeb yog xa cov hluav taws xob loj heev los ntawm lub tshuab hluav taws xob rau lub tshuab hluav taws xob mus rau tus nqi (cov hlau khib nyiab) ntawm cov caj npab electrode. Los ntawm lub cev tshwm sim ntawm arc tawm, hluav taws xob hluav taws xob hloov mus rau hauv lub zog thermal zog, ncav cuag qhov kub txaus kom yaj cov hlau zoo.
2. Technical Classifications: RP, HP, thiab UHP
Cov kev xav tau ntawm kev lag luam sib txawv heev raws li lub zog hluav taws xob. Graphite electrodes yog engineered nyob rau hauv peb qib theem, txiav txim los ntawm cov koob coke ntsiab lus thiab tam sim no ceev muaj peev xwm:
| Qib | Tam sim no ceev (A / cm²) | Daim ntawv thov |
|---|---|---|
| Lub zog tsis tu ncua (RP) | < 17 | Me me steel furnaces, Silicon melting |
| Hwj chim siab (HP) | 18 - 25 | Nruab nrab - loj EAFs rau steel ntau lawm |
| Ultra{0}}High Power (UHP) | > 25 | Niaj hnub nimno siab - muaj peev xwm EAFs, Ladle Refinement |
3. Cov ntawv thov kev lag luam tseem ceeb
Electric Arc Rauv (EAF) Steelmaking
Sawv cev ntau dua 70% ntawm kev noj haus thoob ntiaj teb, graphite electrodes pab txhawb kev rov ua dua ntawm cov khoom siv hlau rau hauv cov khoom tshiab, muab cov pa roj carbon tsawg dua piv rau cov tsoos blast furnace txoj kev.
Ladle Rauv (LF) Refining
Graphite electrodes yog siv nyob rau hauv theem nrab metallurgy kom tswj tau cov hlau kub thiab kho cov tshuaj muaj pes tsawg leeg, kom ntseeg tau tias cov khoom ntawm high - zoo alloy steels.
Submerged Arc Rauv (SAF)
Siv los ua ferroalloys (xws li ferrosilicon thiab silicomanganese), daj phosphorus, thiab calcium carbide, qhov twg cov electrode yog submerged nyob rau hauv cov khoom them.
4. Cov Qauv Txuj Ci thiab Kev Pov Hwm Zoo
Kev ntseeg tau ntawm graphite electrodes yuav tsum ua raws li lub cev thiab tshuaj lom neeg tsis muaj zog kom txo tau tus nqi noj thiab tiv thaiv kev tawg. NtawmZhenAn, peb cov khoom raug txheeb xyuas los ntawm cov qauv ntsuas thoob ntiaj teb:
- Kev tiv thaiv:Feem ntau <5.5 μΩ·m rau UHP qib kom ntseeg tau tias kev xa hluav taws xob zoo.
- Flexural zog:High mechanical zog tiv taus rauv vibrations.
- CTE (Coefficient of Thermal Expansion):Tsawg CTE kom ntseeg tau tias thermal poob siab thaum lub sij hawm cua sov ceev.
5. Cov lus nug nquag nug (FAQ)
Q: Vim li cas graphite yog cov khoom siv rau electrodes?
A: Graphite yog cov khoom siv nkaus xwb uas tuaj yeem sib txuas cov hluav taws xob hluav taws xob siab nrog lub peev xwm los tswj kev ua haujlwm zoo ntawm qhov kub siab tshaj 3,000℃yam tsis muaj melting.
Q: Yuav ua li cas electrode noj cuam tshuam cov nqi tsim khoom?
A: Txij li cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob, siv cov khoom siv siab - zoo UHP electrodes txo tus nqi noj (kg ib tuj ntawm cov hlau), ncaj qha txo qis tag nrho cov kev siv nyiaj.
