Metallurgical Coke Production Methods

Metallurgical coke, ib qho tseem ceeb ntawm cov hlau thiab steelmaking, yog tsim los ntawm cov txheej txheem hu ua coking. Cov txheej txheem no hloov cov thee bituminous rau hauv cov pa roj carbon ntau, cov khoom ntxeem tau nrog cov khoom tshwj xeeb zoo tagnrho rau cov tshuab tawg. Kab lus no tshawb txog ntau yam kev siv los tsim metallurgical coke, qhia txog cov kauj ruam tseem ceeb thiab kev txiav txim siab koom nrog hauv txhua qhov.

Cov txheej txheem Coking ib txwm: Los ntawm thee mus rau Coke

Coal xaiv thiab npaj

Txoj kev mus rau metallurgical coke pib nrog xaiv qhov tsim nyog bituminous thee. Tsis yog tag nrho cov coals raug tsim sib npaug; cov thee xaiv yuav tsum muaj cov yam ntxwv tshwj xeeb, suav nrog cov ntsiab lus tsis zoo ntawm cov ntsiab lus thiab qhov tsim nyog caking kom ntseeg tau tias muaj cov coke tsim nyog. Kev npaj suav nrog kev ntxuav cov thee kom tshem tawm cov impurities xws li sulfur thiab tshauv, uas tuaj yeem cuam tshuam qhov zoo ntawm cov khoom kawg. Cov txheej txheem no feem ntau suav nrog crushing, tshuaj ntsuam xyuas, thiab sib xyaw ntau hom thee kom ua tiav cov khoom xav tau. Ua tib zoo saib rau theem no yog qhov tseem ceeb rau kev tsim cov khoom zoo metallurgical coke.

Them thiab Coking hauv Coke Cub

Npaj cov thee yog them rau hauv coke qhov cub, ntev, nqaim chav rhuab mus rau qhov kub siab heev (kwv yees li 1000 ° C). Cov txheej txheem cua sov, uas tuaj yeem kav ntev li 18-24 teev, tshem tawm cov teeb meem tsis zoo los ntawm cov thee, tawm hauv qab cov khoom seem ntawm cov pa roj carbon monoxide: metallurgical coke. Cov ncu feem ntau yog tsim los ntawm cov cib refractory los tiv thaiv cov cua sov thiab cov tshuaj lom neeg nyob hauv. Cov txheej txheem coking kuj tsim cov khoom lag luam xws li coke cub roj, uas tuaj yeem siv los ua cov khoom siv roj. Niaj hnub nimno coke ncu feem ntau suav nrog kev tswj hwm qib siab los saib xyuas thiab txhim kho cov txheej txheem coking, ua rau txhim kho kev ua haujlwm zoo thiab coke zoo.

Quenching thiab Sizing

Thaum cov txheej txheem coking tiav, qhov kub metallurgical coke yog quenched - sai txias - feem ntau nrog dej. Cov kauj ruam no yog qhov tseem ceeb heev los tiv thaiv kev sib kis ntawm tus kheej. Tom qab quenching, lub coke yog qhov loj me kom tau raws li cov kev xav tau tshwj xeeb rau kev ua haujlwm ntawm qhov cub tawg. Qhov no feem ntau cuam tshuam nrog crushing thiab tshuaj ntsuam kom tau qhov xav tau particle loj tis. Cov kev xav tau tshwj xeeb me me tuaj yeem sib txawv nyob ntawm qhov cub tawg qhov tsim thiab kev ua haujlwm tsis zoo.

Alternative Coking Technologies

Thaum cov tsoos coke qhov cub tseem yog txoj kev tseem ceeb rau metallurgical coke ntau lawm, ntau lwm yam thev naus laus zis tau tshawb nrhiav los txhim kho kev ua haujlwm, txo qis emissions, thiab siv cov coals qis dua. Cov no suav nrog:

Daim Ntawv Coking

Daim ntawv coking koom nrog kev kho cov thee ua ntej rau hauv ib qho tshwj xeeb ua ntej coking, ua rau cov khoom lag luam coke ntau dua thiab zoo dua. Cov cuab yeej no tso cai rau kev tswj kom zoo dua cov txheej txheem coking, txhim kho tag nrho cov txiaj ntsig thiab coke zog. Txoj kev no yog qhov tshwj xeeb tshaj yog thaum siv cov coals uas tsis tshua xav tau cov khoom siv caking.

Lwm Cov Kev Siv Hluav Taws Xob

Kev tshawb nrhiav thiab kev tsim kho txuas ntxiv mus tshawb txog ntau yam tshiab thev naus laus zis txhawm rau txhim kho metallurgical coke ntau lawm. Qhov no suav nrog kev tshawb nrhiav cov txheej txheem uas siv cov khoom siv biomass lossis cov khoom pov tseg los ua cov khoom noj, muab cov kev xaiv zoo dua qub rau kev tsim cov thee. Txoj kev loj hlob ntawm cov thev naus laus zis no feem ntau tau txais nyiaj txiag los ntawm tsoomfwv thiab kev lag luam kev sib koom tes, uas tau tsav los ntawm kev xav tau ntawm ib puag ncig kev ruaj ntseg thiab txhim kho kev siv peev txheej. Qee qhov tsom mus rau kev txo qis emissions thiab txhim kho lub zog efficiency.

Coke Properties thiab Quality Control

Qhov zoo ntawm metallurgical coke raug soj ntsuam raws li ntau yam tsis muaj, suav nrog nws lub zog, porosity, reactivity, thiab cov ntsiab lus sulfur. Cov khoom no ncaj qha cuam tshuam nws qhov kev ua tau zoo hauv qhov cub tawg, cuam tshuam rau kev ua haujlwm ntawm hlau thiab hlau. Kev tswj xyuas nruj nruj yog siv thoob plaws hauv cov txheej txheem tsim khoom kom ntseeg tau tias cov coke zoo sib xws, ua tau raws li qhov xav tau ntawm kev lag luam steel.

Yog xav paub ntxiv txog cov khoom siv hlau zoo coke, xav txog kev tiv tauj Sab hauv Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd ib tug thawj coj nyob rau hauv kev lag luam.

¹ Cov ntaub ntawv ntawm cov khoom siv coke thiab lawv qhov tseem ceeb tuaj yeem pom nyob rau hauv ntau cov phau ntawv metallurgical engineering thiab kev lag luam luam tawm. Cov ntaub ntawv tshwj xeeb yuav txawv nyob ntawm seb hom coal thiab txheej txheem coking siv.
