China Utshise Micro izitena zeAlumina carbon eziporous Al2O3 55% umzi-mveliso kunye nabavelisi | Rongsheng

Inkcazelo emfutshane:

Izitena ze-alumina zekhabhoni zenziwe nge-corundum kunye ne-graphite materails, ebizwa ngokuba yi-alumina carbon refractory brick. I-Whcih luhlobo lwe-carbon indibaniselwano ye-refractory material, Ngokwe-alumina carbon fire brick process, isitena se-aluminiyam ye-carbon yahlulwe ibe yi-aluminiyam yesitena sekhabhoni kunye nezitena ze-aluminiyam ezingatshisiweyo. Izitena ze-aluminium zekhabhoni zisetyenziselwa isilayidi samanzi ngokutyibilikayo, ukuphosa ngokuqhubekayo intonga yeplagi edibeneyo ye-tundish, njl.


Iinkcukacha zeMveliso

Iithegi zeMveliso

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.
