Ama-Grits e-Alumina Amhlophe Ahlanganisiwe Asezingeni Eliphezulu Anesampula Yamahhala
I-alumina emhlophe ehlanganisiwe / i-White CorundumI-Gritiyinto ephikisayo yezinga eliphezulu, eyenziwe ngempuphu ye-alumina esezingeni eliphezulu ngokuncibilikisa ngaphezu kuka-2000 ℃ esithandweni sikagesi se-arc kanye nokupholisa, ehlukaniswe ngobukhulu obuhlukene bokusanhlamvu. I-alumina emhlophe ehlanganisiwe iyinto eluhlaza eyinhloko yokukhiqiza izinto eziphikisayo ezingabunjiwe nezibunjiwe.
I-alumina emhlophe ehlanganisiwe yenziwe ngempuphu ye-alumina ene-sodium ephansi emsulwa ngokuncibilikisa ekushiseni okuphezulu, ukupholisa i-crystallization, bese ichoboza. I-grit ye-alumina emhlophe ehlanganisiwe ilawulwa ngokuqinile ukuze kugcinwe ukusatshalaliswa kosayizi wokusanhlamvu kanye nokubukeka okufanayo.
Ivame ukusetshenziswa ezintweni zokusika i-ladle, izinto zokugijima zensimbi, izinto zokuxuba izibhamu eziphikisayo kanye neminye imikhiqizo ye-monolithic refractory; Ngezinto zokusika ezibunjiwe, isetshenziswa kakhulu ezintweni zokusetshenziswa zekhwalithi ephezulu zezitini ze-corundum, i-corundum mullite, isitini se-plug esinezimbobo zensimbi esicwengisisiwe, isibhamu sokufutha esihlanganisiwe, ukwenza insimbi kanye nomkhakha wokuphonsa oqhubekayo.
Ingasetshenziswa futhi njengezinto zokupholisha, ukupholisha ngokunemba, ukufutha kanye nokumboza, izinto zobumba ezikhethekile
