Coke yog ib qho roj ntawm cov khoom siv dag zog, uas feem ntau yog siv rau hauv qhov cub tawg rau hlau smelting. Nws kuj yog siv nyob rau hauv cov tshuaj, foundry thiab non-ferrous metallurgy industries. Cov khoom siv hluav taws xob no tuaj yeem yog roj av, suab, electrode lossis thee, nyob ntawm cov khoom siv raw uas nws tsim. Feem ntau cov coke yog tsim los ntawm cov thee tawv.

Coke yog ib yam khoom uas tau txais los ntawm cov khoom siv cua sov kom sov li ib txhiab degrees tsis muaj cua. Raws li cov txheej txheem tshuaj lom neeg thiab lub cev, cov khoom tsim tawm yog cov khoom lag luam uas muaj ntau dua 96 feem pua carbon. Tshauv, sulfur, phosphorus thiab lwm yam tshuaj kuj tseem muaj nyob rau hauv coke, qhov ntau npaum li cas, txawm li cas los xij, yuav tsum tsis txhob siab, vim nws tuaj yeem cuam tshuam, piv txwv li, qhov zoo ntawm cov hlau smelted nrog cov roj no. Cov tshuaj no tso cai rau cov coke tso tawm txog 7000 kilocalories thaum hlawv ib kilogram ntawm cov khoom.

Coke yog cov khoom siv raw uas siv, thiab lwm yam, hauv kev tsim cov electrodes. Rau qhov no, cov khoom yog tau los ntawm kev ua cov thee tar pitch (electrode coke) los yog cov khoomdistillation roj av (petroleum coke). Cov kev xaiv tom kawg txawv ntawm cov thee uas lawv muaj cov ntsiab lus tsawg heev ntawm cov khoom ntxiv (cov ntsiab lus tshauv ntawm 0.3 txog 0.8%).

Coke ntau lawm suav nrog ntau theem tseem ceeb, suav nrog:

- xaiv cov qib thee (gas, rog, coking coals sib txawv tuaj yeem siv tau);

- sib tov thiab crushing rau blending;

- kev tshuaj xyuas, kev txhawb nqa, kev cog lus, tshuaj, ziab;

- qhov tso rau hauv qhov cub nrog kev sib haum xeeb tom qab nrog lub coke pusher bar;

- txheej txheem coking ncaj qha (kwv yees li kaum plaub thiab ib nrab teev), raws li qhov tshwm sim ntawm cov coals yog sintered, thiab feem ntau ntawm cov khoom tshaj (ammonia, tar, hydrogen, benzene class hydrocarbons, thiab lwm yam) raug tshem tawm. los ntawm lawv;

- thawb cov khoom tiav rau hauv lub tsheb quenching;

-coke txias nrog dej hauv ntauwd quenching los ntawm ntau nchuav;

- qhov kawg sorting ntawm cov khoom mus rau hauv cov chav kawm ntawm 0-10 mus rau ntau tshaj 60 millimeters.

Coke, daim duab uas tau nthuav tawm saum toj no, yog cov khoom grey yog tias nws yog tsim los ntawm cov khoom siv thee. Nyob rau hauv cov ntaub ntawv ntawm kev siv roj los yog suab nyob rau hauv thawj theem, cov ntxoov ntxoo ntawm cov khoom kawg ntawm cov txheej txheem coking tej zaum yuav txawv me ntsis.

Coke yog ib yam khoom lag luam uas yuav tsum tau muab rau cov smelters tas li. Qhov no yog vim cov txheej txheem thev naus laus zis hauv qhov cub tawg uas ua haujlwm tsis tau nres. Yog ibLub qhov cub tawg tau nres rau ntau tshaj kaum teev, tom qab ntawd cov hlau hauv cov khoom ua kom ruaj khov, thiab nws tsis tuaj yeem raug tshem tawm yam tsis tau rhuav tshem cov qauv ntawm lub cub tawg nws tus kheej. Rau tib lub laj thawj, coking industries yog nyob ntawm cov khoom siv thee, xws li Cov cua sov yog tsim los rau kev ua haujlwm tsis nres rau ib lub hlis twg ntawm ib puas xyoo (20-25 xyoo). Kev txwv cov coke ntau lawm ua rau tsim cov slags hardened nyob rau hauv lub cub tawg chamber, uas yog heev nyuaj rau tshem tawm ntawm qhov ntawd.
