Nyob rau hauv high-temperature industrial sector, kev ua tau zoo ntawm cov khoom siv hauv cov khoom siv hluav taws xob cuam tshuam ncaj qha rau kev tsim khoom thiab cov khoom zoo. Raws li tus neeg sawv cev ntawm cov ntaub ntawv zoo refractory, magnesia-alumina spinel cib, nrog rau lawv cov khoom zoo heev, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev lag luam xws li steel, iav, thiab cement kom tiv taus qhov kub thiab txias yaig thiab txuas ntxiv cov cuab yeej siv, muab kev txhawb nqa zoo rau kev lag luam kub kub.
Ua Kev Lag Luam nrog Kev Ua Haujlwm Zoo Tshaj Plaws
Magnesia-alumina spinel cib yog tsim los ntawm magnesia thiab txhuas oxide los ntawm cov txheej txheem tshwj xeeb. Lawv cov qauv siv lead ua tshwj xeeb ua rau lawv muaj kev ua tau zoo zoo. Cov cib no muaj qhov ua tau zoo ntawm qhov kub thiab txias, muaj peev xwm tiv taus qhov kub thiab txias txog li 1800 ° C. Txawm hais tias nyob rau hauv qhov chaw kub ntev ntev, lawv muaj lub cev ruaj khov thiab cov khoom siv tshuaj lom neeg, tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob los ntawm qhov kub thiab txias.
Thermal shock resistance yog ib qho tseem ceeb ntawm magnesia-alumina spinel cib. Thaum lub sij hawm nquag cua sov thiab cua txias ntawm cov kilns, cov khoom siv refractory zoo tib yam yog qhov ua rau tawg thiab tawg vim thermal stress. Txawm li cas los xij, nrog lawv cov coefficient qis ntawm thermal expansion thiab zoo toughness, magnesia-alumina spinel cib tuaj yeem txo cov kev ntxhov siab thermal, txo qhov kev pheej hmoo ntawm thermal shock puas, ncua kev pab cuam lub neej, thiab txo qhov cub downtime rau kev kho.
Magnesia-alumina spinel cib kuj ua tau zoo heev hauv kev tiv thaiv kev yaig. Lawv muaj kev tiv thaiv zoo heev rau alkaline thiab acidic slag, nrog rau cov roj kub kub, tiv thaiv kev nkag mus ntawm cov khoom tsis zoo thiab tiv thaiv cov qauv kev nyab xeeb ntawm kilns. Txawm hais tias nyob rau hauv ib puag ncig alkaline heev ntawm steel smelting los yog high-kub acidic cua ntawm iav ntau lawm, lawv muaj peev xwm stably ua kom tiav lawv cov kev tiv thaiv.
Cov ntawv thov tob tob thoob plaws ntau qhov kev lag luam
Hauv kev lag luam steel, magnesia-alumina spinel cib yog siv dav hauv cov chaw tseem ceeb ntawm cov converters, ladles, thiab tundishes. Thaum lub sij hawm converter steelmaking, lawv muaj peev xwm tiv taus qhov scouring thiab yaig ntawm high-temperature molten steel thiab slag, kom ntseeg tau qhov kev ncaj ncees ntawm lub converter hauv ob sab phlu. Thaum siv cov ladles thiab tundishes, lawv tuaj yeem txo cov tshuaj tiv thaiv ntawm molten steel thiab cov ntaub ntawv hauv ob sab phlu, txhim kho cov purity ntawm molten steel, thiab txhim kho steel zoo. Tom qab lub tuam txhab steel loj tau txais cov magnesia-alumina spinel cib, kev pabcuam lub neej ntawm nws cov ladles tau nce los ntawm qhov nruab nrab ntawm 60 heats mus rau 120 heats, txo cov nqi tsim khoom.
Hauv kev lag luam iav tsim, magnesia-alumina spinel cib yog cov khoom siv rau qhov tseem ceeb ntawm iav kilns. Nyob rau hauv qhov kub thiab txias regenerators ntawm iav melting furnaces, lawv muaj peev xwm tiv taus qhov yaig ntawm high-temperature iav yaj thiab lub scouring ntawm high-temperature gases, tswj cov txheej txheem stability ntawm lub kiln, txo qhov cub txij nkawm zaus, thiab kev txhim kho cov continuity thiab stability ntawm iav ntau lawm. Tom qab siv cov magnesia-alumina spinel cib, lub voj voog ntawm cov iav kiln tuaj yeem txuas ntxiv los ntawm 2 - 3 xyoos, txhim kho cov txiaj ntsig kev lag luam ntawm kev lag luam.
Thaum lub sij hawm tsim cov cement, qhov kub-kub ib puag ncig ntawm rotary kilns tso cai nruj rau cov ntaub ntawv refractory. Nrog rau lawv qhov kub thiab txias tsis kam, tsis kam tiv taus, thiab tshuaj lom neeg ruaj khov, magnesia-alumina spinel cib ua lub luag haujlwm tseem ceeb hauv thaj chaw hloov pauv thiab kub kub ntawm cov teb kilns, kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm lub kiln lub cev nyob rau hauv high-temperature thiab high-load tej yam kev mob thiab pab txhawb rau cov cement ntau lawm thiab txhim kho zoo.
Professional Purchase Guide
Thaum xaiv magnesia-alumina spinel cib, cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau hais txog: Ua ntej, xyuam xim rau cov tshuaj muaj pes tsawg leeg thiab cov ntxhia hauv cov ntaub ntawv. High-purity magnesia thiab aluminium oxide raw cov ntaub ntawv tuaj yeem ua kom ruaj khov ntawm cov cib. Thib ob, tsom rau kev ua tau zoo ntawm lub cev ntawm cov khoom lag luam, xws li bulk ntom, pom porosity, thiab lub zog txias heev ntawm chav nyob. Cov ntsuas no ncaj qha cuam tshuam qhov zoo thiab kav ntev ntawm cov cib. Thib peb, ntsuam xyuas cov txheej txheem tsim khoom thiab kev tswj xyuas zoo ntawm cov neeg xa khoom. Xaiv cov chaw muag khoom nrog cov cuab yeej tsim khoom siab heev, ua tiav cov txheej txheem tshuaj xyuas, thiab kev lag luam nplua nuj los xyuas kom ntseeg tau cov khoom zoo.
