Isitena se-alumina Ccarbon luhlobo lwekhabhoni edityanisiweyo yezinto ezilahlayo ezenziwe nge-alumina kunye nezixhobo zekhabhoni, ngamanye amaxesha zixutywe nesilicon carbide, isilicon yesinyithi kunye nezinye iibhondi zezinto eziphilayo, ezifana neresin. Uluhlu lwezitena ze-alumina zekhabhoni zomlilo zinezitena ze-aluminium carbonaceous slide, izitena ezifakwe kwi-nozzle, izitena ze-alkali ezixhathisa i-alkali kunye ne-blast furnace aluminiyam isitena sekhabhoni. Iimpawu zezitena ze-alumina carbon refractory zinamandla okuxhathisa umhlwa, uzinzo oluhle lokuthotywa kwe-thermal, amandla aphezulu kunye ne-thermal conductivity ephezulu.
Inkqubo yezitena ze-Alumina Carbon
Isitena sekhabhoni ye-alumina senziwe ngokwamkela ibakala elikhethekileyo le-bauxite clinker, i-corundum, igraphite kunye ne-alumina ephakathi njengezixhobo eziphambili, ezidityaniswe neentlobo ezininzi zezongezo zomgubo ocolekileyo kakhulu. Inkqubo yesitena se-alumina carbon refractory yongeza i-Aluminiyam oxide, i-carbonaceous, imathiriyeli yomgubo wesilicon kunye nezixa ezincinci zezinye izinto ezikrwada kwimathiriyeli ekrwada, emva koko usebenzise i-asphalt, isibophelelo, iresin okanye emva kwezithako, ukuxuba, ukucinezela ukwenza, malunga ne-1300 ℃ sintering. ekunciphiseni umoya.
Iimpawu zeAlumina Carbon Brick
- ukuxhathisa okuqinileyo kwi-corrosion,
- uzinzo oluhle lomothuko we-thermal,
- amandla aphezulu,
- high conductivity thermal.
Ukuhlelwa kweAlumina Carbon Brick
Izitena ze-alumina zekhabhoni zinokwahlulwa zibe ngamacandelo amabini, isitena se-alumina se-alumina se-carbon kunye ne-alumina magnesia isitena sekhabhoni.
I-Magnesia alumina isitena sekhabhoni, kunye ne-high grade magnesite, i-corundum, i-spinel kunye ne-graphite njengezinto ezibonakalayo, eziboshwe nge-resin, zibonakaliswe ngokumelana ne-slag efanelekileyo.
I-alumina magnesia isitena sekhabhoni, kunye ne-bauxite yezinga eliphezulu, i-corundum, i-spinel, i-magnesite ephezulu yokucoceka kunye ne-graphite njengezinto ezibonakalayo, eziboshwe yi-resin, zibonakaliswa ngokukhukuliseka kunye nokuxhathisa ukubola, ukuxhathisa kwe-spalling.

IAlumina Carbon Brick Application
Izitena ze-alumina zekhabhoni zisetyenziselwa ukufakwa kwe-bosh, istaki kunye nodonga olupholileyo lwesithando somlilo. Magnesia alumina carbon isitena ikakhulu isetyenziselwa ladle umgca slag phezulu nasezantsi. Isitena se-alumina magnesia sekhabhoni sisetyenziswa ikakhulu kwi-ladle slag lining kunye nezantsi.
