Cov khoom siv tseem ceeb rau kev tsim cov graphite hluav taws xob yog roj coke. Ib qho me me ntawm asphalt Coke tuaj yeem ntxiv rau cov hluav taws xob zoo li qub hluav taws xob, thiab cov neeg Sulfur cov ntsiab lus ntawm roj av thiab asphalt coke thiab asphalt coke tsis pub dhau 0.5%. Thaum tsim cov high-zog lossis ultra-siab electre electrodes, koob Coke kuj tseem yuav tsum tau ua. Cov khoom siv raw rau txhuas anode ntau lawm yog roj av coke, thiab cov lus faj sulfur yuav tsum tsis pub tshaj 1.5% mus rau 2%. Roj av coke thiab asphalt coke yuav tsum ua raws li cov qauv kev zoo hauv tebchaws.
Cov Khoom Qhia Khoom Khoom
Graphite hluav taws xob yog tsuas yog siv nyob rau hauv chav tsev kom sov, hluav taws xob arc rau steelmaking, daj ua hluav taws kub, lossis hluav taws xob melting. Tam sim no lawv muaj cov khoom lag luam uas muaj nyob nrog qib siab ntawm kev coj zoo thiab muaj peev xwm tswj hwm cov kev kub siab ntawm cov chaw hnyav. Cov Khoom Siv Zoo Tshaj Plaws Coke hauv HP & UHP Graphite hluav taws xob ua kom cov ntawv thov electrode zoo nkauj. Graphite hluav kuj tseem siv los ua kom ua kom ua cov hlau nyob hauv chav tsev ua kom sov thiab lwm yam txheej txheem smelting.
Tuam txhab Khoom Taw Qhia:
Kuv lub tuam txhab ua lag luam tshaj lij uas tsim thiab muag cov khoom lag luam graphite.
