Mipira ya aluminium refractory imakhala ndi mphamvu zabwino kwambiri, kuuma kwakukulu, luso lapamwamba kwambiri la abrasion, kachulukidwe kambiri, kutentha kwambiri, kukana dzimbiri, kuwononga pang'ono ndi zina zabwino kwambiri. Mipira ya aluminiyamu yakhala ikugwiritsidwa ntchito kwambiri pomaliza ndi kukonza mwakuya mitundu yosiyanasiyana ya ceramic, enamel, galasi, mankhwala ndi zida zina zolimba komanso zolimba.
Katundu wa Mipira ya Alumina Refractory
- Kulimbana ndi Kutentha Kwambiri
- Kukaniza Kutentha Kwabwino
- Mphamvu Zapamwamba Zamakina
- Moyo Wautumiki Wautali
Mapangidwe a Mipira ya Alumina Refractory
Alumina refractory mipira amapangidwa ndi AL2O3, kaolin, synthetic aggregate, mullite crystal ndi zipangizo zina. Malinga ndi kugudubuza ndi atolankhani akamaumba njira. Mipira ya aluminium refractory ili ndi zabwino zamphamvu kwambiri, kukana kugwedezeka kwamafuta, kusinthika kosavuta ndi kuyeretsa, moyo wautali wautumiki ndi zina zotero.
Njira ya Mipira ya Alumina Refractory
Kuti apange mipira ya alumina refractory, electrode imayikidwa pansi pa graphite crucible, ndipo arc ikhoza kuyamba powonjezerapo ufa wa alumina wa mafakitale. Ntchito panopa 1.0kA, voteji 80 ~ 100V. Pambuyo kugunda, monga Al2O3 wosungunuka, Mumakonda pang'onopang'ono, mpaka zinthu madzi odzaza ndi graphite crucible, zinthu madzi kutentha ndi 2200 ~ 2300 ℃. Zitatero, crucible anatsanulidwa ndi yankho. ukutuluka.

Kugwiritsa ntchito Mipira ya Alumina Refractory
Mipira ya aluminium refractory yakhala ikugwiritsidwa ntchito kwambiri pomaliza ndi kukonza mwakuya mitundu yosiyanasiyana ya ceramic, enamel, galasi, mankhwala ndi zida zina zolimba komanso zolimba. Makamaka mipira ya aluminium refractory yoyenera zida zolekanitsa mpweya ndi chitsulo chowotcha ng'anjo yamoto ngati chosungirako kutentha
