I-Corundum mullite refractory castable luhlobo lwamandla aphezulu angamiliselwanga izinto ezi refractory ezithengiswa kwi RS Company, ezinokusetyenziswa kwiziko lesamente. I-Corundum mullite castables inokwenza iipropathi eziphezulu ezifana namandla aphezulu okutyumza, ukuzinza kobushushu obuphezulu, ukuxhathisa ukutshatyalaliswa kwe-thermal, ukunxiba kunye nokumelana nokukhukuliseka kweekhemikhali kwi-lining ye-boiler yesikhululo samandla amakhulu kunye nezinye izixhobo zokushisa eziphezulu. i-refractory corundum mullite castable ingasetyenziswa kwisithando somlilo sensimbi, i-sement kiln, i-glass furnace, i-iron eyenza i-oven, i-ceramic tunnel kiln njalo njalo.
Izinto eziphambili zezinto ezibonakalayo ze-corundum mullite ezixutywe yi-aluminium oxide aggregate, umgangatho ophezulu ococekileyo wendalo we-mullite ore, kunye ne-calcium aluminate samente njenge-agent edibeneyo. icorundum mullite refractory castable yenziwa ngokutshiswa kobushushu obuphezulu sisithando somlilo esiphambili. I-corundum mullite amandla aguquguqukayo kunye namandla oxinzelelo ayanda kuqala kwaye anciphe ngoko ngokunyuka kobushushu bonyango lobushushu. Kwaye xa umxholo wamandla we-alumina yi-5%, amandla e-flexural afikelela phezulu.
Umxholo we-Al2O3 ungaphezulu kwe-90%, kwaye i-corundum mullite insulation castable kunye ne-corundum njengesigaba esiphambili se-crystal sixutywe kunye ne-dispersants efanelekileyo, i-coagulants, i-fibers yensimbi engenasici, edityaniswe ngokwendlela engqongqo. I-refractory corundum mullite castable ineempawu ezininzi, njengamandla aphezulu obushushu, ukuxhathisa ukunxiba kunye nokuchasana nokungcola, ukushisa okuphezulu, ukuxhathisa ukutshatyalaliswa kobushushu, ukunyanzeliswa kwe-corrosion, ukutywinwa kakuhle kunye nokuxinana kwangaphambili.

I-Corundum mullite refractory castable ineempawu zokwandiswa okufanayo, ukuxhathisa ukothuka kwe-thermal, ukuzinza kweqondo lobushushu obuphezulu, amandla obushushu obuphezulu, ukuchasa okuphezulu phantsi komthwalo, inqanaba elisezantsi lobushushu obuphezulu, amandla okutyumza okuphezulu, inqanaba elisezantsi lokutshintsha kwedimensional, ubunzima obuphezulu, okulungileyo. ukumelana nokubola kweekhemikhali, ukubola kunye nokumelana nokunxiba. Ngenxa yeempawu ezinjalo, kunye ne-corundum mullite efakwe kwi-insulation iyahlala isetyenziswa kwaye isetyenziswa ngokubanzi kwiziko loshishino, iziko lobushushu obuphezulu kunye nezinye iindawo eziphambili zobushushu obuphezulu, njenge:
