Rau kev ua haujlwm kub siab hauv kev lag luam, cov khoom siv refractories txhim khu kev qha yog qhov tseem ceeb rau kev ruaj khov thiab kev nyab xeeb ntawm cov khoom siv.Cov khoom siv refractory siab alumina—nrog 45%–90% alumina cov ntsiab lus—sawv tawm ua qhov kev xaiv zoo tshaj plaws, ua tsaug rau nws qhov kev ua tau zoo tshwj xeeb hauv cov chaw kub hnyav. Hauv qab no yog kev piav qhia luv luv ntawm nws cov yam ntxwv tseem ceeb thiab daim ntawv thov.
1. Cov Khoom Tseem Ceeb ntawm High-Alumina Refractory Castable
1.1 Muaj zog tiv taus kub siab
Nws tswj tau qhov ruaj khov ntawm 1600–1800 ℃ mus sij hawm ntev (nrog rau lub sij hawm luv luv rau cov ncov siab dua), ua tau zoo dua li lwm cov uas muaj alumina qis dua. Rau kev ua haujlwm 24/7 xws li kev ua hlau lossis kev tsim cement, qhov no txo qhov kev kaw kev saib xyuas thiab ua kom lub neej ntawm cov khoom siv ntev dua.
1.2 Lub Zog Kho Kom Zoo Dua
Nrog lub zog compressive ntawm 60–100 MPa ntawm chav tsev kub, nws tuav cov khoom hnyav thiab cov khoom loj yam tsis tawg. Qhov tseem ceeb, nws tseem khaws lub zog thaum kub, tiv taus kev poob siab thermal - zoo tagnrho rau cov cub tawg iav uas qhov kub hloov pauv, txo cov khoom puas tsuaj kim.
1.3 Kev Tiv Thaiv Kev Yaig thiab Kev Sib Tsoo
Nws cov qauv ntom ntom tiv taus kev yaig tshuaj (piv txwv li, cov slag yaj, cov pa roj acidic) thiab kev hnav lub cev. Hauv cov hlau hloov pauv, nws tiv taus cov hlau yaj uas ntws sai; hauv cov chaw hlawv khib nyiab, nws tiv thaiv cov pa roj acidic, txo cov kev xav tau kho thiab cov nqi.
1.4 Kev Teeb Tsa Yooj Yim & Kev Siv Tau Ntau Yam
Ua hmoov av loj, nws sib tov nrog dej/cov khoom sib txuas ua ib qho slurry uas nchuav tau, pov rau hauv cov duab tsis sib xws (piv txwv li, cov chav ua kom sov tshwj xeeb) uas cov cib ua ntej tsis tuaj yeem sib phim. Nws tsim cov ntaub thaiv monolithic seamless, tshem tawm "hluav taws xau" thiab haum rau cov tsev tshiab lossis kev kho dua tshiab.
2. Cov Ntawv Thov Kev Lag Luam Tseem Ceeb
2.1 Hlau & Metallurgy
Siv rau hauv cov ntaub thaiv cua sov tawg (bosh/hearth, >1700℃), cov ntaub thaiv hluav taws xob arc (EAF), thiab cov ladles—tiv taus kev yaig hlau yaj thiab kev poob cua sov. Kuj tseem muaj cov kab hluav taws xob reverberatory rau kev smelting txhuas/tooj liab.
2.2 Cement & Iav
Zoo tagnrho rau thaj chaw hlawv cement kiln (1450–1600 ℃) thiab cov ntaub ua ntej cua sov, tiv taus kev puas tsuaj clinker. Hauv kev tsim iav, nws kab cov thoob dej yaj (1500 ℃), tiv taus kev xeb iav yaj.
2.3 Kev Kho Hluav Taws Xob & Kev Kho Khib Nyhiab
Cov kab hluav taws xob boiler uas siv thee hlawv (tiv taus cov tshauv ya) thiab cov chaw hlawv pov tseg (tiv taus 1200 ℃ combustion thiab acidic byproducts), ua kom muaj kev nyab xeeb, ua haujlwm tsawg lub sijhawm tsis ua haujlwm.
2.4 Petrochemical & Tshuaj lom neeg
Cov kab ua cov khoom tawg ua npuas (1600 ℃, rau kev tsim cov ethylene) thiab cov qhov cub ci cov zaub mov (piv txwv li, chiv), tiv taus cov pa roj carbon thiab cov tshuaj lom neeg corrosive.
3. Vim li cas ho xaiv nws?
Lub Neej Ntev Dua:Nws kav ntev dua li cov av nplaum castables 2–3 zaug, txo cov kev hloov pauv.
Tus nqi tsim nyog:Tus nqi pib siab dua raug them los ntawm kev saib xyuas tsawg thiab lub neej ntev.
Kho tau raws li koj xav tau:Cov ntsiab lus alumina (45%–90%) thiab cov khoom ntxiv (piv txwv li, silicon carbide) tsim rau cov haujlwm.
4. Koom tes nrog tus neeg muab khoom uas ntseeg siab tau
Nrhiav cov neeg muag khoom siv cov khoom siv huv si, muab cov qauv tsim tshwj xeeb, cov lus qhia txog kev siv tshuab, thiab kev xa khoom raws sijhawm. Txawm tias hloov kho lub cub tawg hlau lossis txheej hauv lub cub tawg cement, cov khoom siv refractory castable uas muaj alumina siab muab kev ntseeg siab - tiv tauj peb hnub no kom tau txais tus nqi.
