Graphite hluav taws xob yog qhov tseem ceeb rau kev tso hluav taws xob tso hluav taws xob hauv hluav taws xob arc. Lawv cov txheej txheem ntau lawm koom nrog ntau yam khoom siv raw thiab cov txheej txheem ua haujlwm nyuaj. Cov hauv qab no yog cov ntaub ntawv raw tseem ceeb rau Graphite hluav thiab lawv cov haujlwm:
Roj av coke: qhov no yog cov khoom lag luam tau los ntawm cov roj av rov qab los ntawm cov roj av rov qab los yog cov roj av aproleum asphalt tom qab coking. Nws muaj cov yam ntxwv ntawm dub thiab ntxig. Lub ntsiab tivthaiv yog carbon thiab cov hmoov tshauv yog tsawg. Roj roj coke ua lub luag haujlwm hauv kev muab cov qauv yooj yim ntawm cov pa roj carbon hauv cov roj teeb hluav taws xob.
Koob coke: Koob coke yog ib tug zoo coke nrog kev nthuav dav coefficient, uas yog qhov tsim nyog rau kev tsim khoom graphite electrodes uas tuaj yeem tiv taus siab ceev. Kev siv ntawm rab koob coke txhim kho qhov kev coj zoo thiab kub ua rau ntawm graphite electrodes.
Coal Sar Pitch: Ua cov binder, thee sar pitch yog siv rau cov khoom siv carbon raw ua ke los ua cov qauv hluav taws xob tsis sib xws. Cour tar suab ua lub luag haujlwm ua lub luag haujlwm hauv kev sib raug zoo thiab kho hauv cov txheej txheem ntau lawm ntawm graphite electrodes.
Ntxiv rau cov ntaub ntawv saum toj no, cov khoom lag luam graphite kuj tseem yuav cuam tshuam nrog lwm cov kev ua kom zoo nkauj, uas tuaj yeem txhim kho kev ua tau zoo ntxiv rau hauv electrode.
Hauv kev tsim cov txheej txheem tsim ntawm graphite cov ntawv, cov khoom siv raw yuav dhau los ua kev kho dua, ci, nias, nias, nias, nias, nias, nias, nias, ua kom ua cov hluav taws xob arc.
Hauv cov ntsiab lus, kev tsim cov graphite electrodes yog txheej txheem kev ua ntau cov ntaub ntawv roj carbon raw thiab khi rau cov ntaub ntawv ua haujlwm ntawm cov txheej txheem nyuaj. Kev xaiv thiab ua cov khoom siv raw ncaj qha cuam tshuam qhov zoo thiab kev ua tau ntawm graphite electrodes, thiab yog li cuam tshuam cov efficiences thiab nqi ntawm hluav taws xob arc rauv steelmaking.
