Nyob rau hauv kev sib tw toj roob hauv pes ntawm 2026, foundry managers nyob rau hauv tas li lub siab los txo tus nqi thaum nce casting zoo. Ib qho ntawm cov lus sib cav tshaj plaws hauv lub khw muag khoom yog qhov kev xaiv ntawm recarburizer:Graphitized Petroleum Coke (GPC)los yogCalcined Petroleum Coke (CPC).
Thaum "tus nqi nplaum" ntawm CPC qis dua, tus kws tshaj lijtus nqi- tsom xam cov txiaj ntsigqhia tias GPC feem ntau muab ROI zoo dua. Phau ntawv qhia no tshawb txog metallurgical thiab economic logic tom qab xaiv siab -purity carbon additives.
1. Qhov Tseem Ceeb Qhov txawv: Cov Qauv thiab Chemistry
Ua ntej txheeb xyuas cov nqi, peb yuav tsum nkag siab txog tus nqi.
- CPC (Calcined Petroleum Coke):Ua tau ntawm ~ 1,300 degree. Nws muaj "amorphous" carbon, sulfur siab dua (0.5% +), thiab cov qib nitrogen tseem ceeb.
- GPC (graphitized Petroleum Coke):Ua ntawm ~ 3,000℃hauv Acheson rauv. Qhov kub kub no ua rau cov crystalline graphite lattice thiab vaporizes ze li ntawm tag nrho cov impurities.
2. Tus nqi sib piv-Kev ntsuas qhov txiaj ntsig
Cov lus hauv qab no rhuav tshem qhov kev ua haujlwm ntawm txhua yam khoom siv.
| Feature | Calcined Petroleum Coke (CPC) | ZhenAn hwm GPC | Kev cuam tshuam nyiaj txiag |
| Cov pa roj carbon absorption | 70% - 82% | 92% - 95% | GPC xav tau 15% cov khoom siv tsawg dua. |
| Nitrogen ntsiab lus | 0.5% - 1.0% | <0.03% (300ppm) | GPC tshem tawm cov nqi pinhole seem. |
| Cov ntsiab lus sulfur | 0.5% - 3.0% | <0.05% | GPC txuag ntawm desulfurization agents. |
| Dissolution ceev | qeeb | Instantaneous | GPC txo lub sijhawm hluav taws xob rau lub tshuab hluav taws xob. |
| Slag Formation | Siab | Tsawg kawg (<0.5% Ash) | GPC ncua lub neej ntawm cov ntaub ntawv refractory. |
3. Kev dhia dej tob: Tus nqi zais ntawm kev siv CPC
Thaum CPC txuag nyiaj ntawm daim ntawv xa nyiaj thawj zaug, nws qhia "cov nqi zais" uas feem ntau tshaj qhov nyiaj khaws cia:
A. Tus Pinhole Defect Tax
High nitrogen hauv CPC yog qhov ua rau muaj roj porosity (pinholes) hauv cov hlau ductile. Ib qho kev tsis lees paub cov khoom tuaj yeem raug nqi ntau txhiab daus las -ntau tshaj tus nqi sib txawv ntawm ib tuj ntawm CPC thiab GPC.
B. Kev Siv Hluav Taws Xob & Lub Sijhawm Melt
Vim GPC muaj cov qauv graphitic, nws dissolves yuav luag tam sim ntawd. CPC yuav siv sij hawm ntev rau "boil" thiab integrate rau hauv lub yaj. Nyob rau hauv lub siab - ntim foundry, txo txhua lub voj voog yaj los ntawm 5 feeb tsuas yog txuag tau hluav taws xob ntau thiab nce txhua xyoo.
C. Refractory Erosion
CPC feem ntau muaj cov hmoov tshauv thiab impurity ntau dua. Cov impurities no hnov mob nrog lub qhov cub lub refractory hauv ob sab phlu, tsim kev txhoj puab heev slag uas shortens lub phiaj xwm lub neej ntawm lub cub tawg. SivZhenAn qhov qis -ash GPCtiv thaiv koj cov cuab tam ntau - lab daus las.
4. Case Study: xam ROI
Xav txog qhov chaw tsim khoom tsim tau 1,000 tons ntawm cov hlau hlau hauv ib lub hlis, xav tau kom nce carbon los ntawm 1.0%.
- Siv CPC (80% Absorption):Koj xav tau 12.5kg ntawm CPC ib tuj hlau.
- Siv ZhenAn GPC (95% Absorption):Koj tsuas xav tau 10.5kg ntawm GPC ib tuj hlau.
- Qhov tshwm sim:Koj txuag 2 tons ntawm cov khoom ib hlis. Thaum koj ua tau rau hauvtxo tus nqi seemthiabqis nqi hluav taws xob, GPC "keeb" dhau los ua qhov kev xaiv muaj txiaj ntsig ntau dua.
5. ZhenAn Ferroalloy: Koj tus khub hauv Carbon Optimization
NtawmZhenAn Ferroalloy, peb tsis yog muag carbon; peb muab kev daws teeb meem metallurgical. Nrog rau ntau tshaj 30 xyoo ntawm kev paub thiab pab neeg tshaj lij ntawm 200+, peb tswj tag nrho cov txheej txheem graphitization kom ntseeg tau tias koj cov specs tau ntsib txhua zaus.
- Kev sib raug zoo:Peb cov khoom sib xyaw ua ke ua kom ntseeg tau tias GPC koj yuav hnub no zoo ib yam li qhov koj yuav xyoo tom ntej.
- Lab Verified:Txhua batch raug sim rau N, S, thiab Fixed Carbon hauv peb lub xeev - ntawm - lub - art facility.
- Ntiaj teb no Logistics:Peb muab cov dej noo- pov thawj ntim thiab xa khoom sai los ntawm Tuam Tshoj cov chaw nres nkoj loj kom ntseeg tau lub Hoobkas- tshiab zoo ntawm koj lub qhov rooj.

FAQ
Q1: Kuv puas tuaj yeem sib xyaw GPC thiab CPC kom txuag tau tus nqi?
Qee qhov chaw tsim khoom siv "split-them" txoj kev, tab sis rau siab -kawg hlau hlau lossis kev nyab xeeb- qhov tseem ceeb ntawm tsheb, qhov kev pheej hmoo ntawm nitrogen porosity los ntawm CPC ua rau 100% GPC qhov kev nyab xeeb, nqi ntau dua - xaiv tau zoo.
Q2: Kuv yuav txheeb xyuas li cas yog tias GPC kuv yuav yog tag nrho graphitized?
High-GPC zoo muaj cov xim hlau nplaum thiab tawm ntawm qhov tsaus, oily cim rau ntawm daim ntawv. Yog hais tias cov khoom yog npub thiab pob zeb -zoo li, nws tus nqi nqus yuav nyob ze rau CPC.
Q3: Tus nqi sib piv rau GPC hauv Q2 2026 yog dab tsi?
Nrog rau cov nqi hluav taws xob ruaj khov nyob hauv Suav teb, peb pom lub qhov rais ruaj khov. Txawm li cas los xij, raws li qhov kev thov rau EV roj teeb anodes (uas kuj siv GPC) nce, kev ruaj ntseg ntev - daim ntawv cog lus tam sim no yog qhov zoo rau cov chaw tsim khoom.
