Izitena zeSilica ezinganyangekiyozizinto ezikhuselayo ezisemgangathweni ophezulu ezisetyenziswa kakhulu kwiindawo ezahlukeneyo zoshishino ezinobushushu obuphezulu.
1. Ulwazi oluSisiseko
Izinto eziphambili:Yinto enokuchasana ne-asidi ene-silicon dioxide (SiO₂) njengeyona nto iphambili, edla ngokuba nomxholo ongaphezulu kwe-93%, kwaye eyezitena ze-silica ezikumgangatho ophezulu ingafikelela kwi-96%.
Ulwakhiwo oluqhelekileyo lweekhemikhali:Ngaphandle kweSiO₂, ikwanayo nenani elincinci le-Al₂O₃ (malunga ne-0.8% - 1%), i-MgO (malunga ne-0.001%), i-CaO (malunga ne-0.002%), kunye ne-Fe₂O₃ (malunga ne-0.7% - 1.5%).
Iimpawu Zomzimba:Ukungaguquguquki ngokubanzi kuphakathi kwe-1770°C kunye ne-2000°C. Ukungaguquguquki phantsi komthwalo we-0.2MPa yi-1630°C - 1680°C. Amandla okutyumza abandayo yi-30 - 35MPa, ubuninzi bobuninzi yi-1.8g/cm³, kwaye i-porosity ebonakalayo yi-21% - 22%.
2. Inkqubo yeMveliso
Inkqubo yemveliso ibandakanya ukukhethwa kwezinto eziluhlaza, ukubumba, ukutshisa, kunye nokupholisa. Izinto eziluhlaza eziphambili yi-quartz, kwaye izinto zokubopha ezifana nelayimu kunye nezinto eziphilayo zongeza. Emva kokuba zenziwe zibe ziindawo ezingenanto zezitena, zitshiswa kubushushu obuphezulu be-1350°C - 1430°C. Inkqubo yokutshisa ifuna ulawulo oluchanekileyo lobushushu, kwaye inkqubo yokupholisa nayo kufuneka yenziwe kancinci ukuze kuthintelwe ukuqhekeka okubangelwa kukutshintsha komthamo ngokukhawuleza.
Iimbonakalo:
1. Ukumelana okunamandla nokukhukuliseka kwe-asidi ye-slag:Izitena zesilika zinokumelana kakhulu nezinto ezirhabaxa ezifana ne-asidi slag kunye nesinyithi esinyibilikisiweyo, okuqinisekisa ubomi bazo obude.
2. Ubushushu bokuthambisa umthwalo ophezulu:Ubushushu bokuthambisa umthwalo wezitena ze-silica bufikelela kwi-1640-1670℃, kwaye umthamo uzinzile xa usetyenziswa ixesha elide kubushushu obuphezulu.
3. Uzinzo oluhle lwevolumu:Kubushushu obuphezulu be-1600℃, izitena ze-silica zinokugcina isakhiwo sizinzile kwaye zibe nesantya esiphantsi sokurhubuluza.
4. Uzinzo oluphezulu lweekhemikhali:Izitena zeSilica zinokumelana kakuhle nee-oxides ezifana ne-Al2O3, i-FeO, i-Fe2O3, kodwa azikwazi ukumelana kakuhle ne-alkaline slag (ezifana ne-CaO, i-K2O, i-Na2O).
