GPC 98.5% Graphitized Petroleum Coke Rau Hlau Casting
Graphitized Petroleum Coke yog tsim los ntawm cov roj av zoo coke nyob rau hauv qhov kub ntawm 2600 degree. Nws yog dav siv los ua qhov zoo tshaj plaws ntawm recarburizer rau kev tsim cov hlau zoo. Nws tseem tuaj yeem siv rau hauv cov yas thiab roj hmab ntau lawm ua ib qho ntxiv.

Kev piav qhia
Graphitized petroleum coke yog cov khoom siv roj av dub lossis grey tawv tawv tawv nrog cov xim hlau luster thiab porosity. Nws yog granular, columnar lossis acicular carbon lub cev tsim los ntawm crystallization ntawm me me graphite.Petroleum coke yog tsim los ntawm hydrocarbons, muaj ntau tshaj 98.5 feem pua carbon, nitrogen, chlorine, sulfur thiab hnyav hlau tebchaw.

Yam ntxwv
1) Qhov loj me me yog nruab nrab, qhov porosity loj, thiab qhov nqus nrawm nrawm.
2) Cov tshuaj muaj pes tsawg leeg yog cov ntshiab, cov pa roj carbon ntau, tsis tshua muaj leej faj, cov khoom xyaw tsis zoo yog qhov me me, qhov nqus tau siab.
3) Cov khoom muaj cov qauv siv lead ua zoo thiab txhim kho lub peev xwm nucleation ntawm thawj cov hlau molten. Thaum lub sij hawm inoculation, tus naj npawb ntawm nodular graphite cam khwb cia hlau yog nce, thiab graphite core yog ntxiv rau cov hlau yaj ntawm lub cub hluav taws xob, thiab kev faib ntawm homogeneous graphite nyob rau hauv lub casting yog refined.
4) Kev ua tau zoo thiab ruaj khov. Cov neeg ua haujlwm carburizing zoo tuaj yeem pab txo tus nqi ntawm smelting thiab txhim kho qhov zoo ntawm smelting hlau thiab castings.
