Isitena seSilica Mullite
Izitena zeSilica mullitesisixhobo esirhabaxa esikumgangatho ophezulu. Izinto eziphambili ezisetyenziswayo ziquka i-alumina bauxite clinker ephezulu kunye ne-silicon carbide, ezenziwe ngeenkqubo ezifana nokuxuba, ukubumba, ukomisa kunye nokudubula ngobushushu obuphezulu. Inyathelo eliphambili linqanaba lokudubula ngobushushu obuphezulu, elenza isakhiwo sekristale ye-mullite efanelekileyo ngokulawula ngokufanelekileyo ubushushu kunye nomoya. Inokurhabaxa okuphezulu, ukumelana nokuguguleka okuhle kunye nokumelana okuhle nokutshayiswa kobushushu. Ingagcina uzinzo kwiindawo ezinobushushu obuphezulu kwaye akukho lula ukuyiqhekeza okanye ukuyisusa.
Izitena ze-silica mullite andalusiteikakhulu zenziwe nge-bauxite ekhethekileyo ene-alumina ephezulu, i-silicon carbide enkulu yekristale, i-andalusite, i-corundum emhlophe exutywe kunye nezinye izinto ezikrwada. Zenziwe ngokongeza izibophelelo kunye nezongezo ezikumgangatho ophezulu, kwaye zenziwe ngokubumba okuxineneyo okuphezulu kunye nokusila kobushushu obuphezulu. Le nkqubo yemveliso iqinisekisa uxinano oluphezulu kunye neempawu zomzimba ezibalaseleyo zezitena ezibomvu ze-silicon-molybdenum.
Uphawu:
Izitena zeSilica mullite:Ukuchasana okuphezulu; Ukumelana okuhle nokutsha kobushushu; Ukumelana okuhle kweekhemikhali; Amandla aphezulu oomatshini; Ukwanda okuphantsi kobushushu.
Izitena ze-andalusite ze-silicon mullite:Amandla aphezulu kunye nokumelana nokuguguleka; Ukuqina okuhle; Ukusebenza kakuhle kwe-thermal insulation; Ukusebenza kakuhle kubushushu obuphezulu; Ukumelana okuphezulu kwe-thermal shock.

Izitena ze-silica mullite andalusitezisetyenziswa kakhulu kwiindawo zokutshintsha kunye neendawo zokupholisa zee-oven ezinkulu neziphakathi zesamente ezijikelezayo. Ngenxa yokumelana kwayo nomlilo okugqwesileyo kunye nokumelana nokuguguleka, izitena ezibomvu ze-silicon-molybdenum zinokuphucula ubomi benkonzo kunye nokusebenza kwezixhobo ngempumelelo.
Kwii-oven zesamente ezijikelezayo,izitena ze-silica mulliteZisetyenziswa kakhulu kwiindawo zokutshintsha, kwiindawo zokufudumeza kwangaphambili, kwiipayipi zomoya eziphezulu, kwii-preheaters ezikwinqanaba ezintlanu, nakwii-chutes zokukhupha i-lime kiln. Azikwazi ukumelana nokukhukuliseka, ukuqhekeka, kunye nokuzinza okuhle kobushushu.
