I-China lightweight high alumina eshisayo efaka izitini ifektri nabakhiqizi | Rongsheng

Incazelo emfushane:

Isitini esiphezulu se-alumina siwuhlobo 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 ngamabanga amathathu: Okuqukethwe kweBanga I - Al2O3 > 75%; Ibanga II - okuqukethwe kwe-Al2O3 kungu-60-75%; grade III - Al2O3 okuqukethwe 48-60%.

Isicelo:

Izitini eziphakeme ze-alumina ezisetshenziswa kakhulu zisetshenziswa kakhulu ukwakha izindwangu zangaphakathi zezimboni, njengeziko eliqhumayo, iziqhumane ezishisayo, ingaphezulu lesithando somlilo kagesi, i-reverberator, ihhavini likasimende elijikelezayo nokunye. Ngaphandle kwalokho, izitini eziphakeme ze-alumina nazo zisetshenziswa kabanzi njengezitini zokuhlola ezivuselelayo, isivalo sesistimu yokuphonsa eqhubekayo, izitini ze-nozzle, njll.
