Isitini se-Alumina Ccarbon siwuhlobo lwezinto eziphikisayo zekhabhoni ezenziwe nge-alumina ne-carbon materials, ngezinye izikhathi ezixutshwa ne-silicon carbide, i-silicon yensimbi nezinye izibopho eziphilayo, njenge-resin. I-alumina carbon fire brick ehlukahlukene ine-aluminium carbonaceous slide brick, i-cast nozzle brick, i-alkali resistant aluminium carbon brick kanye ne-blast furnace aluminium carbon brick. Izici zezitini ze-alumina carbon refractory ziwukumelana nokugqwala okuqinile, ukuzinza okuhle kokushaqeka okushisayo, amandla aphezulu kanye ne-thermal conductivity ephezulu.
Inqubo ye-Alumina Carbon Brick
Isitini sekhabhoni ye-alumina senziwa ngokuthatha i-bauxite clinker yebanga elikhethekile, i-corundum, i-graphite ne-alumina ephakathi njengezinto zokusetshenziswa eziyinhloko, ezihlanganiswe nezinhlobo ezimbalwa zezithasiselo zempushana ezinhle kakhulu. Inqubo yesitini se-alumina carbon refractory ingeza i-Aluminium oxide, i-carbonaceous, i-silicon powder materials kanye nenani elincane lezinye izinto zokusetshenziswa endaweni eluhlaza, bese usebenzisa i-asphalt, i-binder, i-resin noma emva kwezithako, ukuxuba, ukucindezela ukwakha, cishe ku-1300 ℃ sintering. ekunciphiseni umkhathi.
Izici ze-Alumina Carbon Brick
- ukumelana nokugqwala okuqinile,
- ukuzinza okuhle kwe-thermal shock,
- amandla aphezulu,
- high conductivity ezishisayo.
Ukuhlukaniswa kwe-Alumina Carbon Brick
Isitini sekhabhoni ye-alumina singahlukaniswa ngezigaba ezimbili, isitini sekhabhoni ye-alumina kanye nesitini se-alumina magnesia sekhabhoni.
I-Magnesia alumina carbon brick, enezinga eliphezulu le-magnesite, i-corundum, i-spinel ne-graphite njengezinto zokusetshenziswa, eziboshwe nge-resin, ibonakala ngokumelana okuhle kwe-slag.
I-Alumina magnesia carbon brick, enezinga eliphezulu le-bauxite, i-corundum, i-spinel, i-high purity magnesite kanye ne-graphite njengezinto zokusetshenziswa, eziboshwe nge-resin, zibonakala ngokuguguleka nokumelana nokugqwala, ukumelana ne-spalling.

Isicelo se-Alumina Carbon Brick
Isitini sekhabhoni ye-alumina sisetshenziselwa ulwelwesi lwe-bosh, isitaki kanye nodonga lokupholisa lwesithando somlilo. I-Magnesia alumina carbon brick isetshenziselwa ikakhulukazi umugqa we-ladle ophezulu naphansi we-slag. Isitini sekhabhoni ye-alumina magnesia sisetshenziswa ikakhulukazi ulwelwesi lwe-ladle slag naphansi.
