Inkcazo emfutshane:

Izitena zomlilo zesilicon zezezinto ezichasayo zesilicon, izitena zesilika luhlobo lweemveliso zezinto ezichasayo ezisemgangathweni ezinomxholo weSiO2 ongaphezulu kwe-93%. Izitena ezichasayo zesilika zineempawu ezintle zokuchasana kakuhle nokugqwala kwe-asidi, ukuqhuba kakuhle kobushushu, ukuchasana okuphezulu phantsi komthwalo ngaphezulu kwe-1620℃. Kwaye izitena zesilika zineziqwenga zokumelana nokukhukuliseka kwe-asidi enamandla, ukuchasana okuphezulu phantsi komthwalo, kunye nokuzinza komthamo kubushushu obuphezulu. I-silicon rerfractory brik isetyenziswa kakhulu kwi-oven ye-coke, kwiziko elivulekileyo, kwi-oven yeglasi, kwi-oven ye-ceramic, kwi-oven ye-blast, njl.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Izitena ezichasene ne-silica ziyachasana ne-asidi kwaye zinokumelana okuhle nokukhukuliseka kwe-asidi. Ukuchasana kwezitena ze-Slica phantsi komthwalo kufikelela kwi-1640~1690℃, ubushushu bokuqala bokuthamba bubonakala yi-1620~1670℃ kwaye uxinano lokwenyani yi-2.35g/cm3. Izitena zomlilo ze-silicon zinokusebenza kubushushu obuphezulu ixesha elide kwaye zigcine uzinzo lomthamo ngaphandle kokutshintsha. Izitena ezichasene ne-silicon zinomxholo we-SiO2 ongaphezulu kwe-94%. Izitena ze-silica zinamandla aphezulu obushushu kunye nokumelana nokutshayiswa kobushushu obuphantsi. Izitena zomlilo ze-silica zenziwe nge-silica ore yendalo njengezinto eziluhlaza, zongezwa imineralizer efanelekileyo ukukhuthaza i-quartz emzimbeni oluhlaza oguqulwe waba yi-tridymite kwaye zitshiswa kancinci kubushushu be-1350~1430℃ kubushushu obuphantsi. Xa kushushu ukuya kuthi ga kwi-1450℃, kukho i-1.5~2.2% yokwanda komthamo iyonke. Oku kwandiswa emva kokwandiswa kuya kwenza ukusika okudibeneyo kutywinwe kwaye kuqinisekise ukuba ulwakhiwo lugcina umoya ungena kakuhle kwaye unamandla esakhiwo.

Ukwakhiwa kweSitena soMlilo seSilica

Ibhloko yomlilo yeSilicon yisitena esirhabaxa esinomthamo we-silica ongaphezulu kwe-93%, i-50%-80% ye-tridymite, i-10%-30% ye-cristobalite, i-quartz kunye nesigaba seglasi, malunga ne-5%-15%. Ukwakheka kweminerali kwezitena ze-silicate ikakhulu yi-quartz kunye ne-quartz, kunye nenani elincinci le-quartz kunye ne-vitreous. I-quartz yesikali, i-quartz ye-quartz kunye ne-quartz eseleyo zitshintsha kakhulu kumthamo ngenxa yokutshintsha kwesimo sekristale kubushushu obuphantsi, ngoko ke uzinzo lobushushu lwesitena esirhabaxa se-silicate alukho kakuhle kubushushu obuphantsi. Kwinkqubo yokusebenzisa, ukufudumeza nokupholisa okucothayo kungaphantsi kwe-800 ℃, ukuze kuthintelwe ukuqhekeka. Ngoko ke akufuneki kube ngaphantsi kwe-800 ℃ ubushushu obuphezulu.

Inkqubo Yokuvelisa Izitena Zomlilo weSilica

Izitena zomlilo zeSilicate zenziwe nge-quartzite ene-mineralizing agent encinci. Xa zitshiswa kubushushu obuphezulu, izitena ze-silica refractory mineral composition yenziwa yi-scale quartz, i-quartzite quartz, iglasi kunye nezinye izicubu zesigaba esiyinkimbinkimbi ezenziwe kubushushu obuphezulu, kwaye umxholo we-AiO2 ungaphezulu kwe-93%. Phakathi kwezitena ze-silica ezitshayelwa ngcono, umxholo we-scale quartz ngowona uphezulu, obanga i-50% ~ 80%. I-cristobalit yayilandela, ibalelwa kwi-10% ukuya kwi-30% kuphela. Umxholo we-quartz kunye nesigaba seglasi utshintshatshintsha phakathi kwe-5% kunye ne-15%
