Rau kev lag luam kub kub ua haujlwm, txhim khu kev qha refractories tseem ceeb heev rau cov cuab yeej siv tau ntev thiab kev nyab xeeb.High-alumina refractory castable-nrog 45% - 90% alumina cov ntsiab lus - sawv tawm raws li kev xaiv saum toj kawg nkaus, ua tsaug rau nws qhov kev ua tau zoo tshwj xeeb hauv qhov hnyav thermal. Hauv qab no yog ib qho kev qhia luv luv ntawm nws cov yam ntxwv tseem ceeb thiab kev siv.
1. Core Properties ntawm High-Alumina Refractory Castable
1.1 Muaj zog tiv taus kub kub
Nws tuav cov txheej txheem kev ncaj ncees ntawm 1600-1800 ℃ mus sij hawm ntev (nrog rau lub sij hawm luv luv tsis kam mus rau siab dua peaks), outperforming qis-alumina lwm. Rau kev ua haujlwm 24/7 xws li steelmaking lossis cement ntau lawm, qhov no txiav kev kaw haujlwm thiab txuas ntxiv lub neej ntawm cov cuab yeej siv.
1.2 Superior Mechanical Strength
Nrog 60-100 MPa compressive lub zog ntawm chav tsev kub, nws tuav qhov hnyav thiab cov ntaub ntawv ntau yam tsis muaj tawg. Qhov tseem ceeb, nws tuav lub zog nyob rau hauv tshav kub, tiv thaiv thermal shock - zoo tagnrho rau cov iav melting rauv qhov kub thiab txias, txo cov nqi hauv ob sab phlu.
1.3 Erosion & Scour Resistance
Nws cov qauv ntom ntom tiv taus cov tshuaj yaig (piv txwv li, molten slag, acidic gases) thiab hnav lub cev. Nyob rau hauv steel converters, nws resists ceev-ntws molten hlau; nyob rau hauv khib nyiab incinerators, nws fends tawm acidic flue gases, txo cov kev xav tau thiab cov nqi kho.
1.4 Yooj yim Installation & Versatility
Raws li bulk hmoov, nws sib tov nrog dej / binder rau hauv cov dej slurry, nrum rau hauv cov duab tsis sib xws (xws li, kev cai rauv chav tsev) uas ua ntej tsim cib tsis tuaj yeem sib phim. Nws tsim ib qho seamless monolithic hauv ob sab phlu, tshem tawm "tawg hluav taws" thiab haum rau kev tsim kho tshiab lossis rov ua dua tshiab.
2. Cov ntawv thov kev lag luam tseem ceeb
2.1 Hlau & Metallurgy
Siv nyob rau hauv blast furnace linings (bosh / hearth,> 1700 ℃), hluav taws xob arc rauv (EAF) linings, thiab ladles - tiv thaiv molten hlau yaig thiab kub poob. Tsis tas li cov kab reverberatory furnaces rau txhuas / tooj liab smelting.
2.2 Cement & iav
Zoo tagnrho rau cov cement kiln burning aav (1450-1600 ℃) thiab preheater linings, withstanding clinker abrasion. Hauv kev tsim iav, nws cov kab melting tank (1500 ℃), tiv thaiv molten iav corrosion.
2.3 Kev kho hluav taws xob & pov tseg
Kab hluav taws xob hluav taws xob boiler rauv (tiv thaiv ya tshauv) thiab cov khib nyiab incinerator chambers (nrog rau 1200 ℃ combustion thiab acidic byproducts), kom ntseeg tau tias muaj kev nyab xeeb, qis-downtime ua haujlwm.
2.4 Petrochemical & Tshuaj
Cov kab hluav taws xob hluav taws xob (1600 ℃, rau kev tsim cov ethylene) thiab cov pob zeb ci ci (xws li cov chiv), tiv taus cov pa roj carbon monoxide thiab cov tshuaj corrosive.
3. Vim li cas thiaj xaiv Nws?
Lub neej ntev:Siv sijhawm 2-3x ntev dua li cov av nplaum castables, txo kev hloov pauv.
Nqi-zoo:Tus nqi pib siab dua yog offset los ntawm kev saib xyuas qis thiab kev ua neej ntev.
Customizable:Alumina cov ntsiab lus (45% -90%) thiab additives (piv txwv li, silicon carbide) tailor rau tej yaam num.
4. Koom tes nrog ib tus neeg muab kev ntseeg siab
Nrhiav cov neeg siv khoom siv cov ntaub ntawv siab dawb huv, muab cov qauv kev cai, kev taw qhia, thiab xa khoom raws sij hawm. Txawm hais tias kev kho dua tshiab rau lub cub tawg lossis hauv ob sab hauv cov cement kiln, high-alumina refractory castable muab kev ntseeg siab - hu rau peb hnub no rau nqe lus.
