Nyob rau hauv lub realm ntawm high-temperature industrial ua hauj lwm, qhov kev thov rau check, kub-resistant cov ntaub ntawv yog tsis-negotiable. Los ntawm steelmaking furnaces mus rau cement kiln, cov cuab yeej raug kub heev, tshuaj yaig, thiab cov neeg kho tshuab hnav yuav tsum muaj kev tiv thaiv txhim khu kev qha kom ntseeg tau tias kev ua haujlwm tau zoo thiab siv tau ntev. Qhov no yog qhov twgcorundum castablesawv tawm raws li cov khoom hloov pauv kev ua si, muab kev ua haujlwm tsis sib xws uas ua tau raws li cov qauv kev lag luam nruj tshaj plaws.
Corundum castable yog cov khoom siv refractory feem ntau ntawm corundum (aluminium oxide, Al₂O₃) raws li kev sib sau thiab matrix, ua ke nrog cov khoom zoo thiab cov khoom ntxiv. Nws cov khoom tshwj xeeb yog los ntawm cov yam ntxwv tseem ceeb ntawm corundum, uas boasts lub melting point tshaj 2000 ° C, zoo thermal stability, thiab superior mechanical zog. Tsis zoo li cov khoom siv refractory ib txwm muaj, corundum castable muaj qhov sib xyaw ua ke ntawm kev yooj yim thiab ua haujlwm ntev - nws qhov dej ntws tso cai rau kev yooj yim rau kev teeb tsa hauv cov duab thiab cov qauv, thaum nws cov qauv ntom ntom tiv thaiv kev tawg, tawg, thiab tshuaj tua kab mob los ntawm slags, acids, thiab alkalis.
Ib qho txiaj ntsig tseem ceeb ntawm corundum castable yog nws cov versatility thoob plaws kev lag luam. Hauv kev lag luam steel, nws tau siv dav hauv ladles, tundishes, thiab moj tej tawg rauv hauv ob sab phlu, qhov twg nws tiv taus molten steel kub thiab aggressive slag tshwm sim. Steel manufacturers cia siab rau corundum castable los txo downtime los ntawm cov khoom tsis ua hauj lwm, raws li nws ntev kev pab cuam lub neej txhais mus rau tsawg dua txij nkawm thiab txo nqi ua hauj lwm. Rau kev lag luam cement, corundum castable yog siv rau hauv cov cement kiln hloov chaw thiab tertiary cua ducts, enduring siab kub thiab abrasive cement clinker. Nws tiv thaiv thermal poob siab ua kom cov khoom tseem nyob ruaj khov txawm tias thaum lub sij hawm kub hloov pauv sai, ib qho kev sib tw hauv kev tsim cov cement.
Tshaj li cov hlau thiab cov cement, corundum castable excels nyob rau hauv non-ferrous metallurgy, iav manufacturing, thiab pov tseg incineration nroj tsuag. Nyob rau hauv non-ferrous smelting (xws li, tooj liab, txhuas), nws tiv thaiv corrosion los ntawm molten hlau thiab fluxes, tiv thaiv cov khoom tseem ceeb xws li smelting furnaces thiab crucibles. Iav factories siv corundum castable nyob rau hauv regenerators thiab rauv chaw nres nkoj, qhov chaw uas nws tswj kev ncaj ncees nyob rau hauv tas mus li kub kub thiab tshuaj lom neeg raug los ntawm iav melts. Cov khib nyiab incineration tau txais txiaj ntsig los ntawm nws txoj kev tiv thaiv rau cov pa roj carbon monoxide thiab cov hmoov tshauv abrasion, ua kom lub neej ntev ntawm cov khoom siv hluav taws xob thiab txo cov kev pheej hmoo ntawm ib puag ncig.
Lwm qhov tseem ceeb ntawm corundum castable yog nws qhov kev ua tau zoo. Cov neeg tsim khoom tuaj yeem kho qhov muaj pes tsawg leeg ntawm corundum (xws li, dawb corundum, xim av corundum, tabular corundum) thiab cov khoom siv ntxiv los kho cov khoom siv rau cov kev xav tau tshwj xeeb. Piv txwv li, high-alumina corundum castable (Al₂O₃ cov ntsiab lus ≥ 90%) muaj kev tiv thaiv kev kub ntxhov rau ultra-high-temperature ib puag ncig, thaum cov cement qis lossis ultra-low-cement formulations txhim kho qhov ntom ntom thiab txo qhov porosity, txo qis slag nkag. Tsis tas li ntawd, lub teeb yuag corundum castable xaiv muab thermal rwb thaiv tsev yam tsis muaj kev cuam tshuam cov neeg kho tshuab lub zog, zoo tagnrho rau kev siv hluav taws xob txuag hluav taws xob.
Thaum xaiv corundum castable, nws yog ib qho tseem ceeb rau kev koom tes nrog tus neeg muag khoom muaj npe nrov uas ua raws li cov qauv zoo thoob ntiaj teb (xws li ISO, ASTM). High-quality corundum castable undergoes nruj zoo tswj, kom ntseeg tau tias kev ua tau zoo ib yam, ruaj khov tshuaj muaj pes tsawg leeg, thiab txhim khu kev qha installation zog. Cov neeg muag khoom uas muaj kev txawj ntse tseem tuaj yeem muab kev txhawb nqa ntawm qhov chaw, suav nrog kev taw qhia txog kev xaiv cov khoom, cov lus qhia sib xyaw, thiab cov lus qhia txog kev txhim kho tom qab kev txhim kho, ua kom muaj txiaj ntsig ntawm koj cov peev txheej.
Nyob rau hauv niaj hnub kev sib tw kev lag luam toj roob hauv pes, txo downtime, txo tus nqi txij nkawm, thiab txhim kho kev ua haujlwm zoo yog qhov tseem ceeb tshaj plaws. Corundum castable muab rau txhua qhov chaw, muab cov txiaj ntsig zoo, kev daws teeb meem ntev rau cov ntawv thov kub. Nws qhov tshwj xeeb kub tsis kam, corrosion kuj, thiab ntau yam ua rau nws cov khoom ntawm kev xaiv rau kev lag luam nrhiav kev txhim kho cov khoom tsim tau thiab kev ntseeg tau.
Txawm hais tias koj ua haujlwm steel zeb, cement cog, iav Hoobkas, lossis cov chaw pov tseg, corundum castable tuaj yeem hloov pauv koj cov haujlwm kub. Kev nqis peev hauv qhov zoo corundum castable niaj hnub no thiab paub qhov txawv ntawm cov cuab yeej ua haujlwm, kev ua haujlwm ntev, thiab cov txiaj ntsig hauv qab. Hu rau peb pab neeg ntawm cov kws tshaj lij refractory kom paub ntau ntxiv txog peb cov kev hloov kho corundum castable daws teeb meem thiab ua thawj kauj ruam mus rau optimizing koj cov txheej txheem kev lag luam.
