Waxqabadka badeecada:Waxay leedahay xasillooni mugga heerkul sare oo xoog leh, iska caabin shoog kulayl ah oo aad u fiican, iska caabbinta xidhashada, caabbinta daxalka kiimikada iyo sifooyin kale.
Isticmaalka ugu muhiimsan:Inta badan loo isticmaalo aagagga kala-guurka ee foornada wareega sibidhka, foornooyinka burburka, marinnada hawada sare, iyo qalabka kale ee kulaylka ee u baahan caabbinta shoogga kulaylka.
Tilmaamaha alaabta:Sida walxaha aasaasiga ah ee warshadaha refractory, leben alumina sare waxay leeyihiin sifooyin refractoriness sare, xad sare heerkulka jilcin (qiyaastii 1500 ° C), iyo caabbinta nabaad wanaagsan. Waxaa si weyn loogu isticmaalaa foornada warshadaha ee warshadaha kala duwan. Si kastaba ha ahaatee, , Sababo la xiriira content wajiga sare corundum leben alumina sare caadiga ah, kiristaalo wajiga corundum in alaabta sintered waa weyn, iyo dildilaaca iyo diiray u nugul in ay dhacaan marka ay la kulmaan qaboojinta degdeg ah iyo xaaladaha kululaynta. Xasiloonida shoogga kulaylka ee ka hooseeya 1100 °C xaaladaha qaboojinta biyaha waa kaliya Waxay gaari kartaa 2-4 jeer. Nidaamka wax soo saarka sibidhka, iyada oo ay ugu wacan tahay xaddidaadda heerkulka sintering iyo shuruudaha waxqabadka ee alaabta refractory si loogu hoggaansamo maqaarka foornada, lebenka sare ee alumina waxaa loo isticmaali karaa oo keliya aagga kala-guurka ee foornada wareega, dabada foornada iyo preheater foornada burburka .
Lebenka sare ee aluminium-ka-soo-baxa waa leben-aluminium-aluminium-sare leh oo leh sifooyin-ka-hortaag ah oo la soo saaray oo ku saleysan clinker-aluminium-sare oo lagu daray ZrO2 ama walxo kale. Waxaa loo qaybin karaa laba qaybood, mid waa leben-alumina-sare ee ka-hortagga-ka-hortagga leh oo ay ku jiraan ZrO2, kan kalena waa nooca ugu horreeya ee lebenka aluminiumka sare-ka-hortagga ah oo aan ku jirin ZrO2.
Lebennada sare ee aluminium-ka-soo-baxa waxay u adkeysan karaan culeysyada kulaylka sarreeya, ha lumin mugga waxayna leeyihiin ballaarin labis ah, ha gurguuran ama dumin, waxay leeyihiin xoog heerkul caadi ah oo aad u sarreeya iyo kulayl heerkul sare leh, heerkul jilicsan oo sarreeya, iyo leeyihiin iska caabin kulayl wanaagsan. Waxay u adkeysan kartaa saameynta isbeddellada heerkulka degdega ah ama kuleylka aan sinnayn, mana dillaaci doono ama ma dillaaci doono. Farqiga u dhexeeya lebennada aluminiumka sare ee ka-hortagga-flaking-ka ah ee ay ku jiraan ZrO2 iyo lebennada aluminium-ka-hortagga leh ee aan lahayn ZrO2 waxay ku jirtaa qaababkooda kala duwan ee ka-hortagga-flaking-ka. ZrO2-ka kooban alwaaxyada sare ee alumina-ka-hortagga leh waxay isticmaalaan agabka zircon si ay uga faa'iidaystaan iska caabbinta daxalka oo aad u fiican. ZrO2 waxay u adkaysataa nabaad guurka sulfur-chlor-alkali. Isla mar ahaantaana, heerkulka sare, SiO2 ee ku jira zircon waxay mari doontaa isbeddelka marxaladda crystal ka crristobalite ilaa marxaladda quartz, taasoo keentay saameyn mug leh oo gaar ah, sidaas darteed hoos u dhigista khatarta ka hortagga sulfur-chlor-alkali. Isla mar ahaantaana, waxay ka hortagtaa xajinta inta lagu jiro hababka kulul iyo qabow; Lebennada aluminium sare ee ka-hortagga-flaking-ka ah oo aan ku jirin ZrO2 waxaa la soo saaraa iyadoo lagu darayo andalusite lebenka aluminiumka sare. Andalusite-ka ku jira badeecada waxaa loo isticmaalaa mulliteization-ka labaad ee foornada sibidhka. Waxay soo saartaa saameyn yar oo fidinta ah oo aan laga noqon karin si aysan alaabtu u lumin marka la qaboojiyo, waxay ka hortagtaa diiqada yaraanta waxayna ka hortagtaa diirinta qaabdhismeedka.
Marka la barbar dhigo lebennada sare ee aluminium-ka-soo-baxa ee aan ku jirin ZrO2, lebennada-alumina-ka-hortagga leh ee ay ku jiraan ZrO2 waxay leeyihiin iska caabin wanaagsan oo ah dhexgalka iyo nabaad-guurka qaybaha baaruudda, chlorine iyo alkali, si ay u leeyihiin sifooyin ka hortag ah oo ka wanaagsan. Si kastaba ha ahaatee, sababtoo ah ZrO2 waa shay naadir ah, waa qaali , sidaas darteed qiimaha iyo qiimaha ayaa sarreeya.Lebennada aluminium-sare ee ka-hortagga leh ee ay ku jiraan ZrO2 ayaa kaliya loo adeegsadaa aagga kala-guurka ee foornada wareega sibidhka. Lebennada sare ee alumina-ka-hortagga ah ee aan ku jirin ZrO2 ayaa inta badan loo isticmaalaa foornooyinka burburka ee khadadka wax soo saarka sibidhka.
