Waa maxay isticmaalka iyo hababka wax soo saarka ee lebenka refractory alumina sare?

bulukeeti sare oo aluminium refractory ah, taas oo ah, aluminium silicate walxo refractory oo leh maaddo alumina ah oo ka badan 48%. Waxaa la sameeyay oo laga soosaaray bauxite ama walxo kale oo cayriin ah oo leh aluminium sare. Deganaanshaha kulaylka sare, refractoriness ka sarreeya 1770 ℃. Iska caabbinta slag ayaa ka fiican.

lebenkii jaban ee alumina-sare Inta badan waxaa loo isticmaalaa dahaarka foornooyinka qaraxa, shooladaha qaraxa kulul, saqafyada foornooyinka korontada, foornooyinka qaraxa, foornooyinka dib-u-celinta, iyo kilns rotary ah. Intaa waxaa dheer, lebenka sare ee alumina ayaa sidoo kale si ballaaran loo isticmaalaa sida leben jeegaga regenerative hearth furan, furaha loogu shubo nidaamka, lebenka buka, iwm leben aluminium sare ah halkaas oo leben dhoobo ah oo buuxin kara shuruudaha.

Habka wax-soo-saarka ee lebenka caagga ah ee aluminium sare iyo leben dhoobo ah ayaa asal ahaan isku mid ah. Kaliya halbeegyada nidaamka qaarkood ayaa kala duwan. Waxa kale oo jira habab ay ka mid yihiin burburin → isku darka → samaynta → qalajinta → toogashada → kormeer → baakadaha. Cadaadiska cadaadisku wuxuu ku fiican yahay heerkul hooseeya laakiin wax yar ayaa la dhimay heerkulka sare, markaa isku-buufinta foornada ayaa ka yar 1 mitir. Habka wax-soo-saarka ee leben-ka-soo-baxa aluminium-sare iyo leben dhoobo-clinker ah oo badan ayaa la mid ah. Farqiga ayaa ah in saamiga clinker ee maaddooyinka ay ka sarreeyaan, taas oo noqon karta ilaa 90%-9%. Tusaale ahaan, lebennada aluminiumka ah ee sarreeya sida Ⅰ iyo Ⅱ guud ahaan waa 1500～1600℃ marka lagu rido foornada tunnel-ka.

Ku dhaqanka wax-soo-saarka ayaa caddeeyey in ka hor inta aan la burburin, clinker-aluminium-sare si adag loo kala soocay oo loo kala saaray, laguna kaydiyay heerar. Isticmaalka clinker bauxite iyo habka shiidida dhoobada isku dhafan waxay hagaajin kartaa tayada alaabta.

Mid ka mid ah sifooyinka shaqada ee muhiimka ah ee lebenka sare ee alumina waa xoogga qaabdhismeedka heerkulka sare, kaas oo inta badan lagu qiimeeyo heerkulka jilcin ee culeyska. Heerkulka sare ee gurguurta ayaa sidoo kale loo cabbiraa si ay u muujiso xoogga qaabdhismeedka heerkulka sare. Natiijooyinka imtixaanku waxay muujinayaan in heerkulka jilicsanaanta ee culeyska uu kordho korodhka al2O3.

Kor ku xusan waa hordhac u ah isticmaalka iyo habka wax soo saarka ee lebenka refractory alumina sare, waxaan rajeynayaa inay ku caawin doonto adiga.
