Iibhola ze-alumina refractory zinomgangatho olungileyo wokuqina okuphezulu, ukuqina okuphezulu, isakhono esigqwesileyo sokukrazula, ukuxinana kwezambuku ezishinyeneyo, ukusebenza kobushushu obuphezulu, ukuxhathisa umhlwa, ukungcoliseka okuncinci kunye nezinye iipropathi ezigqwesileyo. Iibhola ze-alumina zisetyenziswe ngokubanzi ekugqibeni nasekuqhubeni ubunzulu iintlobo ezahlukeneyo ze-ceramic, i-enamel, iglasi, iikhemikhali kunye nezinye izinto ezishinyeneyo nezilukhuni.
Iipropati ze-Alumina Refractory Balls
- Ukumelana nobushushu obuphezulu
- Ukumelana nobushushu obulungileyo
- Amandla oomatshini aphakamileyo
- Ubomi Obude Benkonzo
Ukuqulunqwa kwe-Alumina Refractory Balls
Iibhola ze-alumina eziphikisayo zenziwe nge-AL2O3, i-kaolin, i-synthetic aggregate, i-crystal mullite kunye nezinye izinto. Ngokwendlela yokuqengqeleka kunye nendlela yokucofa. Iibhola ze-aluminium refractory zineenzuzo zokomelela okuphezulu, ukuxhathisa ukutshatyalaliswa kwe-thermal, ukutshintshwa ngokufanelekileyo kunye nokucoca, ubomi obude benkonzo kunye nokunye.
Alumina Refractory Balls Inkqubo
Ukuze wenze iibhola ze-alumina refractory, i-electrode ibekwe phantsi kwe-graphite crucible, kwaye i-arc inokuqaliswa ngokudibanisa inani elithile le-industrial alumina powder. Ukusebenza ngoku 1.0kA, i-voltage 80 ~ 100V.Emva kokubetha, njengoko i-Al2O3 etyhidiweyo, ilayishwa ngokuthe ngcembe, de ulwelo olubonakalayo luzaliswe yi-graphite crucible, ubushushu bezinto zolwelo yi-2200 ~ 2300 ℃.Emva koko, i-crucible igalelwe kunye nesisombululo iyaphuma.

Ukusetyenziswa kwe-Alumina Refractory Balls
Iibhola ze-alumina refractory zisetyenziswe ngokubanzi ekugqibeni nasekuqhubeni nzulu iintlobo ezahlukeneyo ze-ceramic, i-enamel, iglasi, iikhemikhali kunye nezinye izinto ezinzima kunye nezilukhuni. Ngokukodwa iibhola ze-aluminiyamu eziphikisayo ezifanelekileyo kwisixhobo sokwahlula umoya kwi-accumulator yobushushu kunye nentsimbi yokuqhumisa iziko lokufudumeza igesi njengesithambiso sokugcina ubushushu.
