Alumina Ccarbon zvidhinha imhando yekabhoni musanganiswa refractory zvinhu izvo zvakagadzirwa nealuminium uye kabhoni zvinhu, dzimwe nguva zvakasanganiswa nesilicon carbide, simbi silicon uye mamwe organic bond, senge resin. alumina kabhoni yemoto zvidhinha zvakasiyana ine aluminium kabhoni inotsvedza zvidhinha, yakakandwa nozzle zvidhinha, alkali inodzivirira aluminium kabhoni zvidhinha uye blast furnace aluminium kabhoni zvidhinha. alumina kabhoni refractory zvidhinha maficha akasimba corrosion resistance, yakanaka thermal shock kugadzikana, kusimba kwepamusoro uye yakakwirira yekupisa conductivity.
Alumina Carbon Brick Process
Alumina kabhoni zvidhinha inogadzirwa nekutora yakakosha giredhi bauxite clinker, corundum, graphite uye yepakati alumina semakuru emidziyo, yakasanganiswa nemhando dzinoverengeka dzepamusoro pehupfu hwekuwedzera. Maitiro ealumina carbon refractory zvidhinha ari kuwedzera iyo Aluminium oxide, kabhoni, silicon poda zvinhu uye zvidiki zvezvimwe zviwanikwa kune yakabikwa, wobva washandisa asphalt, binder, resin kana mushure mezvigadzirwa, kusanganisa, kudzvanya kuumba, kutenderedza 1300 ℃ sintering. mukuderedza mhepo.
Zvimiro zveAlumina Carbon Brick
- yakasimba corrosion resistance,
- kugadzikana kwakanaka kwekushisa kwekushisa,
- simba guru,
- high thermal conductivity.
Kurongwa kweAlumina Carbon Brick
Alumina kabhoni zvidhinha inogona kukamurwa kuita zvikamu zviviri, magnesia alumina kabhoni zvidhinha uye alumina magnesia kabhoni zvidhinha.
Magnesia alumina kabhoni zvidhinha, ine yakakwira giredhi magnesite, corundum, spinel uye graphite seyakagadzirwa zvinhu, yakasungwa neresin, inoratidzwa nekunaka slag kuramba.
Alumina magnesia kabhoni zvidhinha, ine yakakwira giredhi bauxite, corundum, spinel, yakakwira kuchena magnesite uye graphite seyakagadzirwa zvinhu, yakasungwa neresin, inoratidzirwa nekukukurwa uye kusagadzikana kwemarara, spalling kuramba.

Alumina Carbon Brick Application
Alumina kabhoni zvidhinha inoshandiswa kugadzira bosh, stack uye kutonhora madziro eiyo blast furnace. Magnesia alumina kabhoni zvidhinha inonyanya kushandiswa kune ladle yepamusoro uye yakaderera slag mutsara. Alumina magnesia kabhoni zvidhinha inonyanya kushandiswa kune ladle slag lining uye pasi.
