Iivenkile zeFektri ezingama-83% zeZitena eziKhawulezayo/Izitena zeAlumina eziphezulu
Siyazingca ngolwaneliseko olukhulu lwabathengi kunye nokwamkelwa ngokubanzi ngenxa yokufuna kwethu rhoqo izinto ezisemgangathweni ophezulu zombini iimveliso kunye nokulungiswa kwazo.Isitena se-Alumina esiphezulu kunye nesitena somlilo, Sikwabonelela ngenkonzo ye-OEM ehlangabezana neemfuno zakho ezithile. Njengoko sineqela elomeleleyo leenjineli ezinamava kuyilo nophuhliso lwamapayipi, siyawaxabisa onke amathuba okubonelela abathengi bethu ngeempahla ezilungileyo.
Izitena ezirhabaxa ze-alumina ephezuluZiluhlobo lwezinto ezichasayo ze-aluminosilicate kunye ne-alumina njengeyona nto iphambili. Njengoko umxholo we-alumina ungaphezulu kwe-48%, zihlelwa njengezixhobo ezichasayo ezingathathi cala, ezenziwe nge-bauxite okanye ezinye izinto eziluhlaza ezinomxholo ophezulu we-alumina ngokubumba kunye nokugaya.
Udidi:
Ngokusekelwe kumxholo we-alumina, zahlulwe zibe ngamanqanaba amathathu:
Ibanga loku-1: izitena ze-alumina eziphezulu (umxholo we-Al₂O₃ > 75%)
Ibanga lesi-2: izitena ze-alumina eziphezulu (umxholo we-Al₂O₃: 60%~75%)
Ibanga lesi-3: izitena ze-alumina eziphezulu (umxholo we-Al₂O₃: 48%~60%)
IiMilo zeZitena eziQhelekileyo kunye neenketho ezenziwe ngokwezifiso:
Izitena eziqhelekileyo, izitena ze-wedge, izitena ze-checker, izitena ezigobileyo, izitena ze-anchor, izitena ze-universal arch, izitena ze-octagonal, izitena ze-casting, kunye neemilo ezenziwe ngokwezifiso ngokwemizobo/iisampulu zomthengi.
Iimpawu zeFizikokhemikhali:
1. Ukungaguquguquki kwe-refractoribility
Iyakwazi ukumelana namaqondo obushushu aphezulu angaphezu kwe-1770℃, ngokubanzi ukusuka kwi-1750℃ ukuya kwi-1790℃. Ukunganyangeki kwayo kuyanda xa kusanda umthamo we-alumina.
2. Ubushushu bokuthambisa umthwalo
Ngokwesiqhelo yi-1420℃ ~ 1530℃. Ngenxa yomxholo ophezulu we-alumina, umxholo ophantsi wokungcola kunye nokwakheka okuncinci kwesigaba seglasi esinyibilikayo, ubushushu bayo bokuthambisa umthwalo buphezulu kunobo bezitena zodongwe zomlilo.
3. Amandla okucinezelwa ngumkhuhlane
Amandla okuxinana abandayo ezitena ze-alumina eziphezulu zeBakala 1 (LZ-80) yi-≥ 70 MPa, ngelixa ezo ze-alumina eziphezulu zeBakala 3 (LZ-48) ziyi-≥ 40 MPa.
4. Ukumelana neSlag
Izitena ezine-alumina eninzi zisondelelene nezinto ezingathathi cala ezirhabaxa, ezinokumelana nokuguguleka kwe-asidi kunye ne-alkaline slags, kodwa ukumelana kwazo ne-alkaline slags kubuthathaka kunokumelana ne-asidi slags.
5. Ukuqhekeka Okubonakalayo
Ubume obubonakalayo bezitena ze-alumina eziphezulu zeBanga loku-1 yi-≤ 21%, kwaye obo bezitena ze-alumina eziphezulu zeBanga lesi-3 yi-≤ 22%.
