Izitena ze-Sillimanite zihlobo lwezitena ezisemgangathweni eziphezulu kunye ne-refractoriness ephezulu ye-1770 ~ 1830 ℃ kunye ne-refractoriness ephezulu phantsi komthwalo we-1500 ~ 1650 ℃, ipropati yayo yomzimba kunye neekhemikhali ingcono kunezitena eziphezulu ze-alumina. I-Sillimanite iguqula ibe yi-mullite kunye ne-silicon dioxide yasimahla emva kokudubula kobushushu obuphezulu. Izitena ze-Sillimanite refractory ngokubanzi zamkela inkqubo yokuvelisa ukudubula kobushushu obuphezulu kunye nenkqubo yokugalela udaka.
Izitena zomlilo zeSillimanite zeze-refractory engathathi hlangothi. Isitena seSillimanite senziwe ngamaminerali e-sillimante, anokuthi aguquke abe yi-mullite kunye ne-silica yamahhala emva kokudubula kobushushu obuphezulu. Isitena se-sillimanite refractory iveliswa ngeendlela zokutshisa ukushisa okuphezulu kunye nokuphosa.
Izitena ze-Sillimanite zenziwe ngezinto eziphambili ze-sillimanite, i-sillimanite luhlobo lwemathiriyeli ekrwada esemgangathweni kwaye isetyenziselwa ukuvelisa izitena eziphezulu ze-alumina kunye nokunyuka okuphantsi, ukuchasa okuphezulu phantsi komthwalo, ukutshatyalaliswa kobushushu obuphezulu kunye ne-micro-expansive, kunye ne-furnace top. i-sillimanite inokuguqulwa ibe yi-mullite kunye ne-silicon dioxide yamahhala ngokudubula kobushushu obuphezulu. Izitena ze-sillimanite refractory ezibonakalayo kunye nepropathi yeekhemikhali zingcono kunezitena eziphezulu ze-alumina. I-refractoriness yezitena zomlilo ze-Sillimanite yi-1770 ~ 1830 ℃ kwaye iqondo lokushisa elibonakalayo lokuqala lokuthamba yi-1500 ~ 1650 ℃.

Izitena zeSillimanite zisetyenziswa ikakhulu ukwenza iziko lomlilo, umqala wesithando somlilo, inotshi yentsimbi kunye ne-tuyere yesithando somlilo, kunye nokubumba umqala wesithando somlilo seglasi. kunye nezitena ze-sillimanite refractory zisetyenziswa ngokukhohlakeleyo kushishino lweglasi, ishishini lesamente, intsimbi kunye neshishini lesinyithi elingenawo i-ferrous kunye nokutshiswa ngokuxhathisa okulungileyo kwipropathi yokothuka kwe-thermal.
Umzi-mveliso we-rongsheng refractory ugxininisa ekuveliseni izitena zomlilo ze-sillimanite ezikumgangatho ophezulu iminyaka emininzi. Inkampani ye-RS inamava okwaneleyo okuvelisa kunye neteknoloji yokuvelisa. Ukwanayo nenjineli yobuchwephesha ukukubonelela ngeengcebiso zobuchwephesha kwisicelo sakho sokwenyani. Ukuba unombuzo malunga nesitena se-sillimanite refractory, nceda uqhagamshelane nathi ngolwazi olungakumbi lobuchwephesha, ukuthengisa kwethu kuya kukuphendula okokuqala.
