Hauv cov txheej txheem kev lag luam uas vam khom cua sov heev—txij li kev yaj iav mus rau kev smelting hlau—kev xaiv cov khoom siv refractory zoo tuaj yeem ua rau lossis rhuav tshem kev ua haujlwm zoo, kev nyab xeeb, thiab kev siv nyiaj tsim nyog.Silica Refractory Cibsawv tawm ua qhov kev xaiv zoo tshaj plaws rau cov chaw nyob nyuaj no, ua tsaug rau lawv qhov kev tiv taus kub siab heev (txog li 1750 ° C), kev nthuav dav thermal qis, thiab kev tiv taus acid erosion. Tab sis cov cib ruaj khov no xa qhov tseem ceeb tshaj plaws qhov twg? Cia peb piav qhia lawv cov kev siv tseem ceeb thoob plaws cov lag luam tseem ceeb, thiab vim li cas lawv thiaj li yog qhov kev daws teeb meem nyiam rau cov engineers thiab cov thawj coj cog khoom thoob ntiaj teb.
Dab tsi ua rau Silica Refractory Cib Zoo Tshaj Plaws rau Cov Kev Siv Kub Siab?
Ua ntej yuav tham txog lawv cov kev siv, nws yog ib qho tseem ceeb kom nkag siab txog cov yam ntxwv uas ua rau cov cib ci silica tsis tseem ceeb. Tsis zoo li lwm cov khoom siv refractory (xws li cov av nplaum hluav taws lossis cov cib alumina), cov cib silica feem ntau yog ua los ntawm crystalline silica, uas muab rau lawv:
Kev tiv taus cua sov zoo tshaj plaws:Lawv tseem ua kom cov qauv ruaj khov txawm tias kub tshaj 1700°C, ua rau lawv tsim nyog rau cov txheej txheem kub siab tas mus li.
Kev nthuav dav thermal qis:Qhov no txo qhov tawg thiab warping thaum raug rau qhov kub hloov pauv sai (qhov teeb meem feem ntau hauv cov cub tawg hauv kev lag luam).
Kev tiv thaiv acid erosion:Lawv tuav tau zoo tiv thaiv cov pa roj thiab cov slags uas yog cov khoom tseem ceeb rau kev lag luam xws li kev tsim coke thiab kev tsim iav.
Lub neej ua haujlwm ntev:Lawv lub zog ua haujlwm tau ntev ua rau txo qhov xav tau hloov ntau zaus, txo cov nqi kho thiab lub sijhawm tsis ua haujlwm.
Cov khoom no ua rau cov cib ua los ntawm silica refractory rau kev lag luam yog ib qho kev daws teeb meem uas siv tau rau cov lag luam uas xav tau kev ntseeg siab nyob rau hauv cov xwm txheej hnyav.
Kev Siv Tseem Ceeb ntawm Silica Refractory Cib los ntawm Kev Lag Luam
Cov cib ua los ntawm silica tsis yog cov khoom siv "ib qho loj-haum-txhua tus" - lawv cov txiaj ntsig tshwj xeeb sib haum nrog cov kev xav tau tshwj xeeb hauv kev lag luam. Hauv qab no yog cov haujlwm uas lawv ua lub luag haujlwm tseem ceeb, nrog rau lawv daws cov teeb meem tseem ceeb li cas.
1. Coke Ovens: Lub hauv paus ntawm kev tsim hlau
Cov qhov cub Coke yog qhov tseem ceeb rau kev hloov cov thee mus ua coke (roj tseem ceeb rau kev ua hlau), thiab lawv ua haujlwm ntawm qhov kub ntawm 1100 ° C thiab 1300 ° C rau lub sijhawm ntev. Cov cib refractory silica rau cov qhov cub coke yog tus qauv kub ntawm no rau ob qho laj thawj tseem ceeb:
Lawv tiv taus cov pa roj acidic (xws li carbon monoxide thiab sulfur dioxide) uas tso tawm thaum lub sijhawm ua kom cov thee carbonization, tiv thaiv kev puas tsuaj ntawm cov cib thiab cov pa roj xau.
Lawv qhov kev nthuav dav qis ua kom lub qhov cub sab hauv tseem zoo thaum lub sijhawm ua kom sov thiab txias txhua hnub, zam kev tawg kim uas yuav ua rau kev tsim khoom tsis ua haujlwm.
Cov thawj coj ntawm cov nroj tsuag vam khom cov cib ua los ntawm silica uas kub heev hauv cov chav ua kom sov coke thiab cov qhov cua, vim tias txawm tias cov khoom me me uas tsis ua haujlwm kuj tuaj yeem ua rau lub sijhawm tsis ua haujlwm ntau lub lis piam—ua rau poob nyiaj ntau lab daus las hauv cov khoom tsim tawm.
2. Cov Cub Iav Yaj: Xyuas kom cov iav ntshiab thiab sib xws
Kev tsim iav yuav tsum tau yaj cov khoom siv raw (xuab zeb, tshauv dej qab zib, limestone) ntawm qhov kub txog li 1600 ° C, thiab lub hauv paus ntawm lub cub tawg yuav tsum tsis txhob cuam tshuam nrog cov iav yaj (uas yuav ua rau cov khoom kawg puas tsuaj). Cov cib silica rau cov cub tawg iav yog qhov zoo tagnrho vim tias:
Lawv qhov xwm txheej inert tiv thaiv kev tshuaj lom neeg nrog cov iav molten, ua kom lub iav tseem ntshiab thiab tsis muaj cov khoom qias neeg.
Lawv tiv taus qhov kub thiab cov iav uas yaj tas li, txo qhov hnav ntawm daim ntaub thiab ua kom lub cub tawg siv tau ntev dua.
Lawv feem ntau siv rau hauv "superstructure" ntawm cov cub tawg iav (cov ntu sab saud saum cov iav molten), qhov twg qhov kub siab tshaj plaws thiab cov pa roj acid feem ntau concentrated.
Rau cov chaw tsim khoom iav, kev siv cov cib ci uas tiv taus kua qaub txhais tau tias yuav muaj tsawg dua qhov tsis zoo ntawm cov khoom thiab lub sijhawm ua haujlwm ntawm lub cub tawg ntev dua - qhov tseem ceeb rau kev ua tiav cov sijhawm tsim khoom nruj.
3. Cov Qhov Cub Hlau: Kev Tswj Xyuas Kub Heev thiab Slag
Kev tsim hlau muaj ntau yam txheej txheem kub siab, suav nrog cov cub tawg, cov cub hluav taws xob arc (EAFs), thiab cov cub ladle. Cov cib refractory silica rau cov cub hlau zoo tshaj plaws hauv cov chaw no vim tias:
Lawv tiv taus qhov kev ua haujlwm abrasive ntawm cov hlau molten thiab slag, uas tuaj yeem ua rau cov refractories uas tsis ruaj khov sai sai.
Lawv lub peev xwm ua kom sov tau zoo pab tswj qhov kub thiab txias hauv lub qhov cub kom ruaj khov, ua kom cov hlau zoo dua thiab txo kev siv hluav taws xob.
Lawv feem ntau siv rau hauv "qhov cub" (hauv qab) thiab "phab ntsa" ntawm EAFs, qhov twg qhov kub thiab txias ncav cuag 1700 ° C thiab kev ntxhov siab ntawm lub tshuab yog siab.
Cov chaw tsim hlau uas siv cov cib ci uas siv tau ntev qhia tias cov nqi kho qis dua thiab tsawg dua qhov kev kaw tsis tau npaj tseg - cov txiaj ntsig tseem ceeb hauv kev lag luam sib tw heev.
4. Lwm Cov Kev Siv Hauv Kev Lag Luam
Dhau li ntawm coke, iav, thiab hlau, silica fire bricks pom siv rau lwm qhov chaw kub siab, suav nrog:
Cov qhov cub ua los ntawm cov av nplaum:Lawv muab ib daim ntaub ruaj khov rau kev hlawv cov khoom siv ceramics ntawm qhov kub txog li 1600 ° C.
Cov tshuaj reactors:Lawv txoj kev tiv thaiv kua qaub ua rau lawv tsim nyog rau cov reactors uas tuav cov txheej txheem acidic (piv txwv li, kev tsim cov kua qaub sulfuric).
Cov chaw hlawv khib nyiab:Lawv tiv taus qhov kub siab thiab cov pa roj corrosive uas tsim tawm thaum lub sijhawm hlawv cov khib nyiab.
