Hauv kev siv metallurgy niaj hnub no, kev tswj xyuas cov ntsiab lus ntawm cov pa roj carbon monoxide yog qhov tseem ceeb rau kev tsim cov hlau zoo - zoo thiab cam khwb cia hlau. Ntawm ntau yam carbon additives muaj nyob rau hauv kev ua lag luam,Graphitized Petroleum Coke (GPC)tau dhau los ua ib qho ntawm cov khoom siv dav tshaj plaws vim nws cov pa roj carbon purity siab, cov ntsiab lus tsis muaj leej faj, thiab kev nqus tau zoo heev.
Seb siv nyob rau hauvElectric arc rauv (EAF) steelmaking, induction cua sov, ductile hlau ntau lawm, los yoggrey hlau casting, Graphitized Petroleum Cokeplays lub luag haujlwm tseem ceeb hauv kev txhim kho molten hlau zoo thaum txo cov nqi tsim khoom. Nws yog dav lees paub tias yog ib qho ntawm cov txiaj ntsig zoo tshaj plawscarbon raisersmuaj rau kev lag luam metallurgical. GPC yog tsim los ntawm graphitizing calcined petroleum coke ntawm qhov kub siab heev (feem ntau nyob ib ncig ntawm 2500-3000 degree), hloov cov qauv carbon rau hauv kev txiav txim siab graphite lattice nrog txhim kho conductivity thiab carbon absorption.
Graphitized Petroleum Coke yog dab tsi?
Graphitized Petroleum Coke, feem ntau abbreviated liGPC, yog tsim los ntawm graphitizing siab - zoo roj av coke nyob rau hauv tsis tshua muaj kub kub.
Thaum lub sij hawm graphitization, cov qauv hauv cov pa roj carbon hloov pauv los ntawm kev tsis sib xws rau hauv graphite crystals. Qhov kev hloov pauv no tseem ceeb txhim kho:
- Tsau Carbon Cov ntsiab lus
- Cov pa roj carbon absorption
- Hluav taws xob conductivity
- Thermal stability
- Tshuaj Purity
Piv nrog cov roj av zoo tib yam coke,GPCmuaj tsawg dua impurities, ua rau nws tsim nyog rau kev thov metallurgical daim ntaub ntawv uas yuav tsum tau muaj kev ruaj ntseg carbon. Hom siab -qib GPC muaj cov pa roj carbon ntau ruaj nrog cov sulfur thiab tshauv tsawg, ua rau nws siv tau zoo li cov khoom siv rov ua dua tshiab hauv steelmaking thiab foundries.
Vim li cas GPC thiaj li tseem ceeb hauv Metallurgy?
Txhua txoj kev steelmaking poob carbon vim oxidation.
Tsis muaj cov pa roj carbon txaus rov qab:
- Steel hardness txo.
- Cov khoom siv tshuab ua tsis ruaj khov.
- Cov nqi tsim khoom nce ntxiv.
- Cov khoom zoo dhau los ua qhov tsis sib xws.
NtxivGraphitized Petroleum Coketso cai rau steelmakers los kho cov qib carbon uas xav tau sai thiab ua tau zoo.
VimGPCmuaj cov qauv graphitized heev, carbon yaj sai dua rau hauv cov hlau molten dua li ntau cov pa roj carbon additives.
Cov yam ntxwv tseem ceeb ntawm High Quality GPC
HwmGraphitized Petroleum Cokefeem ntau muab:
- High Fixed Carbon
- Tsawg Sulfur
- Tsawg Tshab
- Tsawg Nitrogen
- Tsawg noo noo
- Zoo heev Carbon Recovery
- Ruaj khov Particle Loj
- Ceev Dissolution
Cov yam ntxwv no pab cov nroj tsuag steel txo cov slag tsim thaum txhim kho cov txiaj ntsig thiab cov txheej txheem ruaj khov.
Txawm hais tias specifications txawv los ntawm cov chaw tsim khoom, cov qib sib xws muaj xws li:
| Yam khoom | Tus nqi |
|---|---|
| Tsau Carbon | Ntau dua lossis sib npaug li 98.5% |
| Sulfur | Tsawg dua lossis sib npaug li 0.05% |
| Tshauv | Tsawg dua los yog sib npaug li 0.5% |
| Volatile teeb meem | Tsawg dua los yog sib npaug li 0.5% |
| Moisture | Tsawg dua los yog sib npaug li 0.5% |
Cov pa roj carbon ntau dua thiab qis dua sulfur feem ntau qhia tau zoo dua.

Kev lag luam Ferroalloy
Muaj ntau cov ferroalloy manufacturers sivGPCraws li cov pa roj carbon additive thaum smelting los txhim kho carbon tswj thiab txo impurity input.
Cov khoom siv roj teeb
Ultra- siab- purity graphitized petroleum coke kuj tseem siv los ua cov khoom siv ua ntej rau lithium- ion roj teeb anodes, txawm hais tias qib metallurgical tseem yog daim ntawv thov tseem ceeb rau cov neeg muag khoom feem ntau.
Qhov zoo ntawm GPC Tshaj Li Kev Cai Carbon Additives
Piv nrog cov khoom siv carbon zoo tib yam,Graphitized Petroleum Cokemuab:
✔ Cov pa roj carbon ntau dua
✔ Txo cov kab mob sulfur
✔ Kev tawg sai dua
✔ Nqus cov hlau molten
✔ zoo dua casting zoo
✔ Lower slag tiam
✔ ruaj khov tshuaj muaj pes tsawg leeg
Cov txiaj ntsig zoo no pab txhawb kev txhim kho kev tsim khoom thiab kev ua haujlwm zoo sib xws ntawm metallurgy.
Vim li cas Ntiaj Teb Hlau Mills Nyiam Tsawg Sulfur GPC
Sulfur yog ib qho khoom tsis zoo hauv ntau qib ntawm cov hlau.
Tshaj sulfur tuaj yeem ua rau:
- Kub brittleness
- Weldability tsis zoo
- Txo toughness
- Deg tsis xws luag
Yog li ntawd, ntau cov nroj tsuag steel nyiamTsawg Sulfur Graphitized Petroleum Cokekom txo qis impurity qhia thiab txhim kho cov khoom zoo kawg.
