1. Qhov Kev Xav Tau Ntau Ntxiv ntawm Cov Hlau Zoo
Qhov no yog ib qho ntawm cov yam tseem ceeb uas ua rau kev lag luam ntawm graphite electrodes loj hlob. Kev loj hlob sai ntawm cov lag luam hlau xws li kev tsim kho, tsheb, kev tsim kho vaj tse, aerospace thiab kev tiv thaiv lub teb chaws tau ua rau muaj kev nce ntxiv ntawm kev thov thiab kev tsim khoom hlau.
2. Lub Tshuab Hluav Taws Xob Arc yog Qhov Sib Txawv ntawm Lub Sijhawm
Vim muaj kev tiv thaiv ib puag ncig thiab kev yooj ywm ntau lawm, cov txheej txheem ua hlau hauv cov teb chaws uas tseem tab tom txhim kho tab tom hloov ntawm lub cub tawg thiab lub cub tawg mus rau lub cub tawg hluav taws xob (EAF). Cov hluav taws xob graphite yog lub zog tseem ceeb rau kev siv hlau hauv lub cub tawg hluav taws xob, thiab txog li 70% ntawm cov hluav taws xob graphite siv rau hauv kev ua hlau hauv lub cub tawg hluav taws xob. Kev loj hlob sai ntawm lub cub tawg hluav taws xob ua rau lub peev xwm tsim khoom ntawm cov hluav taws xob graphite yuav tsum tau nce ntxiv.
3. Cov Khoom Siv Hluav Taws Xob Graphite yog Cov Khoom Siv Tau
Lub sijhawm siv ntawm graphite electrode feem ntau yog li ob lub lis piam. Txawm li cas los xij, lub voj voog tsim khoom ntawm graphite electrodes feem ntau yog 4-5 lub hlis. Thaum lub sijhawm siv no, lub peev xwm tsim khoom ntawm graphite electrode yuav raug txo qis vim yog txoj cai hauv tebchaws thiab lub caij cua sov.
4. Koob Coke Qib Siab Tsis Muaj Khoom Siv
Koob coke yog cov khoom siv tseem ceeb rau kev tsim cov graphite electrodes. Nws yog calcined petroleum coke (CPC) uas suav txog li 70% ntawm cov nqi nkag ntawm graphite electrode tsim. Tus nqi nce ntxiv los ntawm cov koob coke tsawg tsawg yog qhov laj thawj tseem ceeb rau kev nce nqi ncaj qha ntawm graphite electrodes. Lub caij no, koob coke kuj tseem siv rau hauv kev tsim cov khoom siv electrode rau lithium roj teeb thiab kev lag luam aerospace. Cov kev hloov pauv no hauv kev muab khoom thiab kev thov ua rau tus nqi ntawm graphite electrode yog qhov tsis zam.
5. Kev Ua Rog Lag Luam Ntawm Cov Tebchaws Loj Hauv Ntiaj Teb
Qhov no ua rau Tuam Tshoj cov hlau xa tawm poob qis heev, thiab yuam kom lwm lub tebchaws nce peev xwm tsim khoom. Ntawm qhov tod tes, nws kuj ua rau kev nce ntxiv ntawm cov khoom xa tawm ntawm graphite electrodes hauv Tuam Tshoj. Tsis tas li ntawd, Tebchaws Meskas tau nce cov se rau cov khoom xa tuaj ntawm Tuam Tshoj, uas ua rau txo qis qhov zoo ntawm tus nqi ntawm Suav graphite electrodes.
