Corundum Mullite Castable Fa'amatalaga
Corundum mullite refractory castable o se ituaiga malosi maualuga unshaped refractory mea mo le faatauina atu i le Kamupani RS, lea e mafai ona faaaogaina i sima kiln. Corundum mullite castables e mafai ona faatino mea maualuluga e pei o le malosi tu'imomomo maualuga, mautu maualuga vevela, te'i te'i vevela, ofu ma vailaau tafia tetee i totonu o le lining o le tele o le afi afi afi ma isi meafaigaluega vevela maualuga. refractory corundum mullite castable e mafai ona faaaogaina i ogaumu uamea, ogaumu sima, ogaumu tioata, ogaumu faia uʻamea, kiln tunnel sima ma isi.
Meatotino a Corundum Mullite Castable
- Malosi maualuga,
- Malosi le ofuina,
- Lelei e tetee i le tafia,
- E lelei tele le mautu o le te'i vevela,
- Tete'e maualuga o le vevela.
Fa'agasologa o le Gausia o Corundum Mullite Castable
O mea autu autu o le corundum mullite castable o le mama alumini oxide aggregate, maualuga le lelei mama mullite ore, ma calcium aluminate sima e avea ma sui so'o. corundum mullite refractory castable ua faia e ala i le vevela maualuga mu e le ogaumu alamanuia alualu i luma. Corundum mullite malosi fefiloi ma compressive malosi faateleina muamua ma faaitiitia i le faateleina o le vevela vevela. Ma a o'o i le 5% le alumina micro power content, e o'o atu le malosi fa'afefete i le pito i luga.
Tulaga o Corundum Mullite Castable
O mea o loʻo i totonu o le Al2O3 e sili atu nai lo le 90%, ma o le corundum mullite insulation castable ma le corundum e pei o le vaega tioata autu o loʻo faʻafefiloi ma faʻasalalauga talafeagai, coagulants, alava uamea, lea e faʻapipiʻiina e tusa ai ma le faʻatonuga saʻo. Refractory corundum mullite castable e tele uiga, e pei o le maualuga o le malosi o le vevela, ofuina-tetee ma anti-scour, maualuga le vevela conduction, vevela teʻi tetee, corrosion tetee, faamaufaailoga lelei ma condensation vave.

Fa'aaogaina o Corundum Mullite Castable
Corundum mullite refractory castable o loʻo i ai foliga o le faʻalauteleina toniga, sili atu le teteʻi vevela, maualuga le vevela voluma mautu, maualuga vevela malosi, maualuga refractoriness i lalo o le uta, maualalo maualuga-vevela fetolofi fua, maualuga le nutimomoia malosi, maualalo laina fua fua faatatau suiga, malo maualuga, lelei tete'e i vaila'au pala, spalling ma ofuina tete'e. Ona o ia uiga, ma corundum mullite insulation castable e umi i le faʻaaogaina ma e faʻaaogaina lautele i fale gaosi oloa eseese, ogaumu vevela maualuga ma isi vaega autu o le vevela maualuga, e pei o:
- Fua, ogaumu fa'avevela, ogaumu fa'avevela,
- ogaumu sima, ogaumu koale,
- Faitotoa o le ogaumu, tatala fafaga, ogaumu u'amea, ogaumu fai u'amea,
- Potu fa'amumu, fa'a'au fa'a'a'au,
- Pula fale eletise tetele, umu tioata.
