Izixhobo eziphambili ze-thermal zeiziko lokunyibilikisa ishishiniibandakanya calcination kunye sintering eziko, itanki electrolytic kunyeiziko lokunyibilikisa.I-lining yendawo yokudubula ye-rotary kiln ngokuqhelekileyo yakhiwe ngezitena eziphezulu ze-alumina, kwaye izitena zodongwe zingasetyenziswa njenge-lining yezinye iindawo.Umaleko wefiber refractory wevawe ubekwe kumaleko wokugquma ubushushu kufutshane neqokobhe leziko, emva koko kwakhiwe umaleko wezitena ezikhaphukhaphu okanye ezikhaphukhaphu.Umgangatho refractory castable ukugalela.
Iqokobhe leseli ye-electrolytic lenziwe ngepleyiti yentsimbi, kwaye umaleko webhodi yokugquma okanye i-fiber refractory ivakala ibekwe ngaphakathi kwiqokobhe, emva koko kwakhiwa izitena ezilula okanye kugalelwe izitena ezikhanyelayo ezikhanyelayo, emva koko zakhiwe ngezitena zodongwe. yenza umaleko ongasebenziyo, kunye nokusebenza kweeseli ze-electrolytic Umaleko unokwenziwa kuphela ngekhabhoni okanye i-silicon carbide izinto ezinqandayo kunye ne-conductivity elungileyo yombane, ukuze uxhathise ukungena kwe-aluminium etyhidiweyo kunye nokukhukuliseka kwe-fluoride electrolyte.Ngaphambili, uluhlu olusebenzayo lodonga lweseli yeseli ye-electrolytic yayakhiwe ngokubanzi ngeebhloko zekhabhoni.Kwiminyaka yakutshanje, iJapan kunye namanye amazwe aseNtshona Yurophu asebenzise izitena ze-silicon carbide ezidityaniswe ne-silicon nitride ukuzakha, kwaye zafumana iziphumo ezilungileyo.
Uluhlu olusebenzayo olusezantsi kwiseli ye-electrolytic ngokuqhelekileyo lwakhiwe ngeebhloko zekhabhoni ezinamajoyina amancinci kwaye zizaliswe nge-carbon paste ukukhusela ukungena kwesisombululo se-aluminium kunye nokuphucula ukuqhuba.
Eyona aluminium isetyenziswa kakhuluizixhobo zokunyibilikisaliziko lomlilo.Isithando somlilo esidibana nesisombululo se-aluminium ngokuqhelekileyo sakhiwe ngezitena eziphezulu ze-aluminium kunye nomxholo we-A1203 we-80% -85%.Xa unyibilikisa i-aluminium yensimbi ecocekileyo, izitena ze-mullite okanye izitena ze-corundum kufuneka zisetyenziswe.Kwezinye iifektri, izitena ze-silicon carbide ezidityaniswe ne-silicon nitride zisetyenziselwa ukwakhiwa kwamatye kwiindawo ezithanda ukukhukuliseka kunye nokuguga, njengokuthambeka kweziko kunye nenkunkuma ye-aluminiyam.Izitena ezizibopheleyo okanye i-silicon nitride-bonded silicon carbide nazo zisetyenziswa njenge-linings ngezitena ze-zircon.Ukuvalwa kwendawo yokuphuma kwe-aluminium, umphumo we-vacuum casting refractory fiber ungcono.I-furnace linings engaqhagamshelani nesisombululo se-aluminium ngokuqhelekileyo yakhiwe ngezitena zodongwe, i-clay refractory castables okanye iiplastiki eziphikisayo.Ukwenzela ukukhawulezisa isantya sokunyibilika kunye nokugcina amandla, izitena ezikhaphukhaphu, izinto zokulahla ezikhaphukhaphu ezikhanyelayo kunye neemveliso zefiber ezichasayo zisetyenziswa ngokubanzi njengemigangatho yokugquma ubushushu.
I-aluminiyam yokunyibilikisa i-oven crucible induction nayo isetyenziswa ngokuqhelekileyo izixhobo.I-lining ngokubanzi yenziwe nge-high-alumina refractory castable okanye i-refractory ramming material kunye ne-A1203 umxholo we-70% -80%, kunye ne-corundum refractory concrete isetyenziswa njenge-lining.
I-aluminiyam etyhidiweyo iphuma kwi-outlet ye-aluminiyam yesithando somlilo ngetanki yokuhamba ye-aluminiyam.I-tank lining yenziwa ngokubanzi ngezitena ze-silicon carbide, kwaye kukwakho neebhloko ezenziwe ngaphambili zesanti ye-silica edibeneyo.Ukuba ibhloko esele ilungisiwe isetyenziswa njengetanki yombane, umphezulu kufuneka ugqunywe ngesanti ye-silica edityanisiweyo okanye Sebenzisa isamente ye-alumina ephezulu edityanisiweyo yesanti ye-silica enokulahlwa njengomaleko okhuselayo.
