Incazelo
Izitini eziphezulu ze-alumina ziwuhlobo lwe-refractory, ingxenye eyinhloko okuyi-Al2O3. Uma okuqukethwe kwe-Al2O3 kungaphezulu kuka-90%, kubizwa nge-corundum brick. Ngenxa yezinsiza ezahlukene, izindinganiso zamazwe ahlukene azihambisani ngokuphelele. Isibonelo, emazweni aseYurophu, umkhawulo ophansi we-Al2O3 wokuqukethwe okuphezulu kwe-alumina refractories ngu-42%. E-China, okuqukethwe kwe-Al2O3 esitini esiphezulu se-alumina ngokuvamile kuhlukaniswa ngamamaki amathathu: Ibanga I - okuqukethwe kwe-Al2O3 > 75%; grade II - Al2O3 okuqukethwe 60-75%; grade III - Al2O3 okuqukethwe 48-60%.
Izici:
1. High refractoriness
2.Amandla okushisa aphezulu
3.Ukuzinza okuphezulu kokushisa
4.I-neutral refractory
5.Ukumelana okuhle ne-asidi kanye nokugqwala okuyisisekelo kwe-slag
I-6.I-refractoriness ephezulu ngaphansi komthwalo
7.Ukushisa okuphezulu ukumelana nokukhasa
8.I-porosity ebonakalayo ephansi

Isicelo:
Izitini eziphakeme ze-alumina zithandwa kakhulu uma kwakhiwa izindwangu zangaphakathi zezimboni, njengezithando zomlilo eziqhumayo, iziqhumane ezishisayo, indawo yomlilo kagesi ephezulu, i-reverberator, i-rotary simende yomlilo nokunye. Ngaphandle kwalokho, izitini eziphakeme ze-alumina nazo zisetshenziswa kabanzi njengezitini zokuhlola ezivuselelayo, isivalo sesistimu yokuphonsa eqhubekayo, izitini ze-nozzle, njll.
FAQ
