Semi Graphitized Petroleum Coke Rau Casting Grey Hlau

Semi-graphitized petroleum coke yog cov qib high-qib carbon recarburizer, feem ntau siv hauv kev tsim cov khoom hlau xws li cam khwb cia grey hlau. Nws cov ntsiab lus siab ruaj khov thiab tsis tshua muaj leej faj thiab nitrogen cov yam ntxwv ua rau nws muaj ntau yam khoom siv, dav siv hauv metallurgy thiab casting industries.

Txheej txheem ntau lawm

Cov txheej txheem tsim khoom ntawm semi-graphitized petroleum coke yog suav nrog cov kauj ruam hauv qab no:

Kev npaj cov khoom siv raw yog thawj kauj ruam hauv kev tsim khoom. Nws yog ib qho tseem ceeb los xaiv cov roj av coke zoo li cov khoom siv raw los lav cov khoom zoo.

Cov kauj ruam tom ntej yog calcination. Cov roj av raw coke yuav tsum tau calcined thiaj li yuav tshem tawm tej yam tsis hloov pauv thiab impurities, thaum ua kom cov ntsiab lus ruaj khov.

Cov kauj ruam tom ntej yog kho cov khoom siv nrog cov txheej txheem graphitization. Tom qab ntawd cov roj av calcined coke yuav tsum muab tso rau hauv lub qhov cub graphitization thiab graphitized ntawm qhov kub siab (feem ntau tshaj 2000 degree) los tsim ib nrab-graphitized petroleum coke.

Cov kauj ruam tom ntej yog crushed thiab tshuaj ntsuam cov khoom. Lub graphitized roj av coke yog ces crushed thiab tshuaj ntsuam los tsim cov khoom ntawm txawv particle qhov ntau thiab tsawg, tailored kom tau raws li cov kev cai ntawm peb cov neeg muas zaub ntau haiv neeg.

Qhov zoo

Lub semi-graphitized petroleum coke muaj cov txiaj ntsig hauv qab no:

Cov khoom boasts ib tug siab ruaj cov ntsiab lus carbon. Nws cov ntsiab lus ruaj khov siab ua kom muaj cov pa roj carbon txaus thaum lub sij hawm casting txheej txheem, lav kev pom zoo hauv cov khoom tiav.

Tsawg leej faj thiab nitrogen cov ntsiab lus: Txo cov pa phem thiab tsis xws luag hauv cov txheej txheem casting.

Zoo reactivity: sai sai yaj thiab tso tawm cov ntsiab lus carbon, nce cov ntsiab lus carbon ntawm casting.

Kev ruaj ntseg zoo: ruaj khov ntawm qhov kub thiab txias, tiv taus oxidation thiab volatilization, ua kom cov txheej txheem du casting.

Daim ntawv thov

Semi-graphitized petroleum coke yog cov khoom siv ntau yam uas tau siv dav hauv grey hlau casting. Nws siv nyob rau hauv cov txheej txheem no tshwj xeeb manifested nyob rau hauv cov nram qab no yam:

Cov pa roj carbon monoxide: Raws li cov pa roj carbon monoxide hauv cov txheej txheem casting, nws muab cov pa roj carbon monoxide txhim khu kev qha, kom ntseeg tau tias cov ntsiab lus carbon ntawm cov casting ua tau raws li qhov yuav tsum tau ua.

Txhim kho kev ua haujlwm zoo: Qhov sib ntxiv ntawm cov roj av coke semi-graphitized tuaj yeem txhim kho microstructure thiab kev ua haujlwm tag nrho ntawm casting, thaum tseem ua rau nws lub zog, hardness, thiab hnav tsis kam.

Txo txo ​​qhov tsis xws luag: Cov tsis muaj leej faj thiab nitrogen cov ntsiab lus ntawm semi-graphitized petroleum coke pab txo qhov tsis xws luag xws li pores thiab slag inclusions thaum lub sij hawm casting txheej txheem, thaum kawg txhim kho qhov zoo ntawm castings.

1. Peb nyiam them nyiaj los ntawm T / T, L / C, D / P; Western Union thiab Paypal kuj ua haujlwm tau.

2. Los ntawm courier, zoo li DHL, UPS, Fedex. Qhov ntawd yog qhov rooj rau qhov rooj, feem ntau, 5-7 hnub los txog.

Los ntawm kev thauj huab cua, feem ntau, 3-4 hnub los txog.

Los ntawm hiav txwv thauj, feem ntau, 15-30 hnub los txog.

Yog tias koj lub sijhawm xa khoom sai, peb xav kom koj xaiv cov khoom thauj los yog huab cua. Qhov no siv rau cov qauv lossis cov khoom me me.

Yog tias koj lub sijhawm xa khoom tsis yog ceev heev, peb xav kom koj xaiv kev thauj mus los hauv hiav txwv, nws pheej yig heev.
