Izitena zeCorundum mullite luhlobo lwezitena ezinganyangekiyo ezenziwe ngezinto ezicocekileyo okanye ezicocekileyo, ikwayibhloko ye-corundum mullite sisitena somlilo se-alumina esiphezulu esenziwe nge-corundum kunye ne-mullite main crystalline phase. Izinto eziphambili zezitena ze-corundum mullite zingeniswa ngaphandle kwipleyiti ye-corundum, i-corundum exutywe kakuhle, yamkela iteknoloji yokongeza umgubo ongcono kakhulu, yenziwe ngezinto zokuxuba, zomisa, zibumba kwaye zitshiswe kwi-shuttle oven enobushushu obuphezulu.
Iimpawu zeCorundum Mullite Brick
- Izinto ezisemgangathweni ophezulu,
- I-corundum yobumsulwa obuphezulu,
- Uzinzo oluqinileyo lomthamo kumaqondo obushushu aphezulu,
- Ibunjwe ngoxinzelelo oluphezulu kunye nobushushu obuphezulu,
- Ukumelana kakuhle nobushushu,
- Ukumelana nokunxiba,
- Ukumelana nokuhlaselwa ngamakhemikhali.
Inkqubo Yokuvelisa Izitena zaseCorundum Mullite
Izitena zeCorundum mullite zenziwe ngezitena ze-mullite ezenziwe ngokwenziwa kwaye iinxalenye ze-mullite zifumaneka, kwaye i-alpha Al2O3 powder yepowder, ingadityaniswa okanye ixutywe iinxalenye ze-corundum ukuze idityaniswe, i-synthetic mullite powder yepowder. I-aggregate kunye nepowder zixutywa ngokwemilinganiselo ethile kunye nobukhulu bengqolowa. Utywala obumdaka bepulp yephepha ene-sulfite busetyenziswa njenge-arhente yokubopha, kwaye izixhobo zongezwa ngokulandelelana okuthile. Zixutywe ngokupheleleyo kwaye zilingane, ngomatshini wokubumba izitena ze-friction okanye i-hydraulic press. I-Adobe emva kokomiswa, yitshise kwi-1650 ~ 1750 ℃.

| Ubuninzi bobuninzi g/cm3 | ≥3.2 | ≥3 | ≥2.8 |
| I-porosity ebonakalayo % | ≤19 | ≤18 | ≤18 |
| I-MPa enamandla okucinezela abandayo | ≥100 | ≥100 | ≥100 |
Ixabiso lezitena zeCorundum Mullite
Ngokubanzi, izitena ze-cordundum mullite zahlulwe zibe zizitena ezisinkiweyo nezixutyiweyo, ixabiso leentlobo ezimbini zezitena ezichasene ne-corundum mullite zahlukile kakhulu kwimarike, ixabiso liphakathi kwamawaka ukuya kwi-10,000. Sicebisa ukuba kukhethwe izitena ezahlukeneyo ze-corundum mullite ngokweendawo ezahlukeneyo ze-oven, kungekuphela nje ukuphucula ubomi besitovu, kodwa nokunciphisa iindleko.
Ukusetyenziswa kweCorundum Mullite Brick kwiFurnace
Izitena zeCordundum mullite zinokudibana ngqo nelangatye, zikwazi ukumelana nokuqhekeka, zikwazi ukumelana nobushushu obuphezulu, zingasetyenziswa njenge-insulation yobushushu kwi-lining ye-furnace yemizi-mveliso enobushushu obuphezulu. Kwakhona izitena zomlilo ze-corundum mullite zingasetyenziswa njengeminye imigangatho yokusebenza ye-furnace yemizi-mveliso, esetyenziswa kakhulu kwishishini le-petrochemical, i-ammonia gasifier enkulu nephakathi kunye nezinto zemagnethi ze-furnace yegesi enezinto, izixhobo ze-furnace yemizi-mveliso enobushushu obuphezulu, njl.njl.
