Peb mam li tshawb nrhiav qhov sib txawv ntawm cov tawv thiab mos coking coals, delve rau hauv cov txheej txheem ntawm nyuaj coking, thiab tshuaj xyuas nws qhov cuam tshuam rau ntau yam kev lag luam. Kawm yuav ua li cas xaiv cov thee zoo rau koj cov kev xav tau tshwj xeeb thiab nrhiav kev daws teeb meem rau ntau nyuaj coking cov teeb meem ntsig txog.

Hard Coking yog dab tsi?

Hard coking hais txog cov txheej txheem ntawm kev tsim metallurgical coke los ntawm high-volatile, low-sulfur bituminous thee. Hom thee no, thaum raug kub kub thaum tsis muaj huab cua, dhau los ua cov txheej txheem ntawm pyrolysis, hloov mus rau hauv cov khoom muaj zog, cov pa roj carbon monoxide hu ua coke. Qhov "hardness" yog hais txog lub cev lub zog thiab kev ncaj ncees ntawm cov coke, uas yog ib qho tseem ceeb rau nws siv nyob rau hauv blast furnaces thiab lwm yam high-temperature metallurgical txheej txheem. Qhov zoo ntawm coke cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ua haujlwm ntawm cov txheej txheem no. Nkag siab txog cov khoom ntawm qhov chaw thee yog qhov tseem ceeb rau kev tsim cov coke zoo tsim nyog rau kev thov. Cov xwm txheej zoo li cov thee cov ntsiab lus tsis hloov pauv, cov ntsiab lus tshauv, thiab cov ntsiab lus sulfur cuam tshuam rau cov khoom kawg ntawm cov khoom.

Cov khoom ntawm Coals Haum rau Hard Coking

Tsis yog txhua lub coals haum rau nyuaj coking. Cov thee zoo tagnrho muaj cov yam ntxwv tshwj xeeb. Cov yam ntxwv no yog qhov tseem ceeb hauv kev ua kom cov khoom siv coke nrog lub zog tsim nyog thiab kev ua haujlwm.

Cov khoom tseem ceeb:

• Cov ntsiab lus siab tsis hloov pauv: Qhov no ua kom muaj cov yas txaus thaum lub sijhawm coking.
• Cov ntsiab lus tsis tshua muaj leej faj: Qhov tseem ceeb heev rau kev txo qis cov pa hluav taws xob tsawg thiab tswj xyuas qhov zoo ntawm cov khoom hlau kawg.
• Cov ntsiab lus tshauv tsim nyog: Cov tshauv ntau dhau tuaj yeem ua rau cov qauv coke tsis muaj zog.
• Tsim nyog fluidity thiab o cov khoom: Cov khoom no txiav txim siab coke qhov kev ntxhib los mos thiab lub zog.

Cov txheej txheem Hard Coking

Cov nyuaj coking txheej txheem feem ntau muaj ob peb theem: thee npaj, them, coking, thiab coke quenching. Coal yog thawj zaug crushed thiab sib tov kom ua tiav cov khoom xav tau. Qhov kev sib xyaw no yog tom qab ntawd them rau hauv qhov cub coke, qhov twg nws tau rhuab mus rau qhov kub siab (ib puag ncig ° C) thaum tsis muaj cua. Cov txheej txheem no tsav tawm cov teeb meem tsis hloov pauv, tawm hauv qab cov khoom siv carbon residue - coke. Lub coke yog ces quenched kom txias nws ua ntej yuav thauj mus rau siv ntxiv. Kev ua tau zoo ntawm cov txheej txheem no cuam tshuam rau tus nqi thiab qhov zoo ntawm cov khoom kawg. Kev ua kom zoo tshaj plaws, xws li ceev faj saib xyuas qhov kub thiab txias thoob plaws hauv cov txheej txheem, feem ntau yog ua haujlwm.

Kev siv ntawm Hard Coke

Hard coke lub ntsiab daim ntawv thov yog raws li ib tug txo tus neeg sawv cev nyob rau hauv blast furnaces rau ironmaking. Nws lub zog siab thiab qhov porosity yog qhov tseem ceeb rau kev txhawb nqa qhov hnyav ntawm lub nra hauv lub cub tawg thiab ua kom yooj yim rau cov roj ntws. Tsis tas li ntawd, nws cov reactivity ua kom muaj txiaj ntsig zoo ntawm cov hlau ore. Ntau ntxiv, kev tshawb fawb tau ua rau hauv lwm daim ntawv thov, tshawb nrhiav nws lub peev xwm hauv lwm cov txheej txheem metallurgical kub thiab carbon-intensive industries.

Kev sib tw thiab yav tom ntej Trends hauv Hard Coking

Cov nyuaj coking kev lag luam ntsib ntau yam kev sib tw. Kev sib ntsib kev nruj nruj ntawm ib puag ncig kev cai cuam tshuam txog kev tso tawm cov sulfur thiab huab cua zoo yog qhov kev txhawj xeeb loj. Kev tshawb fawb txog kev siv tshuab ua kom huv thiab ua kom zoo dua qub yog txuas ntxiv. Tsis tas li ntawd, nrhiav thiab nkag mus rau qhov zoo tshaj plaws coking thee yog qhov nyuaj zuj zus. Kev tsim kho tshiab hauv cov txheej txheem thee sib xyaw thiab lwm cov txheej txheem coking yog qhov tseem ceeb kom ua tau raws li qhov xav tau yav tom ntej. Txoj kev loj hlob ntawm kev hloov pauv hloov mus rau coke hauv steelmaking kuj tseem yog lub hom phiaj ntawm kev tshawb fawb ntau.

Xaiv Txoj Cai Coal rau Hard Coking

Xaiv cov thee tsim nyog rau nyuaj coking yog qhov tseem ceeb. Kev nkag siab txog cov kev cai tshwj xeeb ntawm koj daim ntawv thov thiab cov khoom ntawm ntau hom thee yog qhov tseem ceeb. Qhov no suav nrog kev soj ntsuam kom zoo ntawm cov thee cov tshuaj lom neeg thiab cov yam ntxwv ntawm lub cev, nrog rau kev xav txog yam xws li tus nqi thiab qhov muaj. Tham nrog cov kws tshaj lij hauv kev ua haujlwm kom paub meej tias kev xaiv cov thee zoo tshaj plaws rau koj cov kev xav tau.
