Iibhola ze-alumina ezichaseneyo zinomgangatho olungileyo wokuqina okuphezulu, ubulukhuni obuphezulu, amandla agqwesileyo okukrazula, uxinano olukhulu, ukusebenza kobushushu obuphezulu, ukumelana nokugqwala, ungcoliseko oluncinci kunye nezinye iimpawu ezintle. Iibhola ze-alumina zisetyenziswe kakhulu ekugqibezeleni nasekucubunguleni nzulu iintlobo ezahlukeneyo ze-ceramic, i-enamel, iglasi, iikhemikhali kunye nezinye izinto eziqinileyo neziqinileyo.
Iimpawu zeebhola ze-Alumina Refractory
- Ukumelana nobushushu obuphezulu
- Ukumelana kakuhle nobushushu
- Amandla aphezulu oomatshini
- Ubomi beNkonzo ende
Ukwakhiwa kweebhola ze-Alumina Refractory
Iibhola ze-Alumina refractory zenziwe nge-AL2O3, i-kaolin, i-synthetic aggregate, i-mullite crystal kunye nezinye izinto. Ngokwendlela yokuqengqeleka kunye ne-press molding, iibhola ze-aluminium refractory zineengenelo zokuqina okuphezulu, ukumelana kakuhle nokutsha kobushushu, ukutshintshwa kunye nokucoca okulula, ubomi obude benkonzo, njalo njalo.
Inkqubo yeebhola ze-Alumina Refractory
Ukuze kwenziwe iibhola ze-alumina ezichasayo, i-electrode ibekwa ezantsi kwe-graphite crucible, kwaye i-arc ingaqaliswa ngokongeza inani elithile le-industrial alumina powder. Ukusebenza kwamandla ombane yi-1.0kA, i-voltage yi-80 ~ 100V. Emva kokubetha, njengoko i-Al2O3 inyibilika, ilayisha kancinci kancinci, ide i-material liquid izaliswe yi-graphite crucible, ubushushu bolwelo bolwelo yi-2200 ~ 2300 ℃. Emva koko, i-crucible iyathululwa kwaye isisombululo siyaphuma.

Ukusetyenziswa kweebhola ze-Alumina Refractory
Iibhola ze-Alumina ezichasayo zisetyenziswa kakhulu ekugqibezeleni nasekucubunguleni nzulu iintlobo ezahlukeneyo ze-ceramic, i-enamel, iglasi, iikhemikhali kunye nezinye izinto eziqinileyo neziqinileyo. Ingakumbi iibhola ze-aluminium ezichasayo ezifanelekileyo kwizixhobo zokwahlula umoya kunye ne-steel blast furnace igesi yokufudumeza njengesizalisi sokugcina ubushushu.
