Lo mba siya kuqhubeka ukwazisa ulwahlulo lwezitena zomlilo zokugquma ezikhaphukhaphu kwizitofu zeglasi.
3.Udongweisitena somlilo esikhanyayo esilula. Yimveliso ye-insulation refractory eyenziwe ngodongwe oluphikisayo kunye nomxholo we-Al2O3 we-30% ~ 48%. Inkqubo yayo yemveliso isebenzisa indlela yokongeza yokutshisa kunye nendlela yogwebu. Izitena zomlilo zodongwe ezikhaphukhaphu zinoluhlu olubanzi lwezicelo, ikakhulu ezisetyenziswa njengezinto zokugquma i-insulation layers kwii-kiln ezahlukeneyo zemizi mveliso apho zingadibani nezinto ezityhidiweyo. Ubushushu bayo bokusebenza yi-1200 ~ 1400 ℃.
4. Izitena zokugquma i-aluminium oxide. Imveliso inokumelana nomlilo ophezulu kunye nokuxhathisa ukothuka kwe-thermal, kwaye isetyenziswa ngokuqhelekileyo njengomgangatho ophezulu wokugquma ubushushu kwii-kilns. Ubushushu bayo bokusebenza yi-1350-1500 ℃, kwaye ubushushu bokusebenza beemveliso ezicoceke kakhulu bunokufikelela kwi-1650-1800 ℃. Ziimveliso zokugquma izinto ezenziwe ngezinto ezikrwada ze-corundum edibeneyo, i-alumina e-sintered, kunye ne-alumina ye-industrial.
5. Izitena ze-mullite ezilula. Ukufakwa kwe-thermal kunye neemveliso ezichasayo ezenziwe kwi-mullite njengeyona nto iphambili yemathiriyeli ekrwada. Izitena zokugquma i-Mullite zinokumelana nobushushu obuphezulu, amandla aphezulu, ukuhanjiswa kwe-thermal ephantsi, kwaye zinokudibana ngokuthe ngqo namadangatye, kwaye zilungele ukufakwa kwezitofu ezahlukeneyo zeshishini.
6. Izitena zebhola ze-aluminiyam oxide. Izitena zebhola ze-aluminiyam oxide zisetyenziselwa ukusetyenziswa ixesha elide ngaphantsi kwe-1800 ℃. Inozinzo oluhle lweekhemikhali kunye nokumelana nokubola kumaqondo obushushu aphezulu. Xa kuthelekiswa nezinye izitena zokugquma ezikhaphukhaphu, izitena zebhola ze-alumina ezinobushushu obuphezulu bokusebenza, amandla aphezulu, kunye ne-thermal conductivity esezantsi. Ubuninzi bayo buphinde bube yi-50% ~ 60% ephantsi kuneyemveliso ye-dense refractory yokwakheka okufanayo, kwaye inokumelana nefuthe lomlilo ophezulu wokushisa.
