Lub ntsiab daim ntawv thov teb ntawm calcined coke nyob rau hauv Tuam Tshoj yog electrolytic aluminium kev lag luam, accounting rau ntau tshaj 65% ntawm tag nrho cov nqi ntawm calcined coke, ua raws li cov pa roj carbon, muaj silicon thiab lwm yam smelting industries. Kev siv cov calcined coke li roj yog tsuas yog nyob rau hauv cement, lub zog tsim, iav thiab lwm yam lag luam, accounting rau ib tug me me feem.
Tam sim no, cov khoom siv hauv tsev thiab kev xav tau ntawm calcined coke yog qhov zoo ib yam. Txawm li cas los xij, vim tias kev xa tawm ntau ntawm cov roj av uas tsis muaj sulfur high-end coke, tag nrho cov khoom siv hauv tsev ntawm calcined coke tsis txaus, thiab nws tseem yuav tsum tau xa cov khoom nruab nrab thiab siab sulfur calcined coke rau ntxiv.
Nrog rau kev tsim kho ntau ntawm coking units nyob rau hauv xyoo tas los no, cov zis ntawm calcined coke hauv Suav teb yuav nthuav dav.
Nyob ntawm seb cov ntsiab lus ntawm leej faj, nws tuaj yeem muab faib ua cov sulfur coke siab (cov ntsiab lus sulfur siab dua 3%) thiab qis sulfur coke (cov ntsiab lus sulfur hauv qab 3%).
Tsawg leej faj coke tuaj yeem siv ua anodic muab tshuaj txhuam thiab ua ntej ci anode rau cov nroj tsuag txhuas thiab graphite electrode rau cov nroj tsuag steel.
Qhov zoo tshaj plaws uas tsis muaj sulfur coke (cov ntsiab lus sulfur tsawg dua 0.5%) tuaj yeem siv los tsim cov graphite electrode thiab carbonizing tus neeg sawv cev.
Tsawg sulfur coke ntawm cov khoom siv dav dav (sulphur cov ntsiab lus tsawg dua 1.5%) feem ntau yog siv los ua cov khoom ua ntej ci anodes.
Tsis tshua muaj roj av coke yog tsuas yog siv nyob rau hauv smelting industrial silicon thiab anodic muab tshuaj txhuam ntau lawm.
High-sulfur coke feem ntau yog siv los ua roj hauv cov nroj tsuag cement thiab fais fab nroj tsuag.
Nruam thiab meej sampling thiab kuaj yog ib feem tseem ceeb ntawm peb cov txheej txheem ntau lawm.
High sulfur coke tuaj yeem ua rau cov pa roj paug thaum lub sij hawm graphitization, uas ua rau tawg ntawm cov khoom siv carbon.
Cov hmoov tshauv siab yuav cuam tshuam cov crystallization ntawm cov qauv thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv carbon
Txhua kauj ruam yuav ua tib zoo kuaj, peb xav ua yog raws nraim cov ntaub ntawv tshawb nrhiav.
Raws li ib feem ntawm peb cov txheej txheem zoo txhua pob yuav raug ntsuas tsawg kawg 3 zaug, kom tsis txhob muaj qhov sib txawv.
Tsis muaj ntsuab calcined coke resistivity yog siab heev, nyob ze rau lub insulator, tom qab calcining, resistivity poob sharply, yog inversely proportional rau lub resistivity ntawm roj av coke thiab calcined kub, tom qab 1300 ℃ ntawm calcined roj av coke resistivity txo mus rau 500 μm Ω m. los yog li ntawd.
