High Alumina Refractory Sima Fa'amatalaga
O le sima alumina maualuga e gaosia e ala i le fusi o mea mata filifilia i totonu o le ogaumu faʻapitoa. A mae'a le mālūlū, fa'apala le kiliva e fa'aaoga ai polo mill. O mea mataʻutia o le maualuga o le alumina refractory sima CA-70 o meaʻai calcium mama maualuga ma alumina mama maualuga. E tatau ona fa'afefiloi mea mata e tusa ai ma fua faatatau talafeagai. E tatau ona mu le mea mata ina ia fa'afefiloi se vaega. Ole mea ole Al2O3 e masani ona pulea ile 68% ile 72%. O mea faʻapitoa o le CA ma le CA2.
Meatotino o High Alumi Refractory Sima
- Faʻasaʻo vave, malosi maualuga,
- maualuga refractoriness, maualuga-vevela auaunaga faatinoga,
- Lelei teteʻe i abrasion, maualuga ofu teteʻe,
- Malosi le fa'asusu,
- Fa'atino lelei e tetee atu i le pala,
- Maumau te'i vevela maualuga.
Tulaga lelei ole High Alumina Refractory Sima
1. Lelei faʻatinoga i le vevela vevela, pala, tafia ma abrasion teteʻe,
2. High refractoriness ma sili atu le malosi faʻainisinia,
3.Both fa'alavelave ma fa'aauau pea galuega e talia, fa'aitiitia ta'eta'ei laina,
4. Longer ma mautu le taamilosaga o le olaga e ausia le maualuga maualuga,
5. Suit mo ituaiga uma o ituaiga uʻamea, faʻaitiitia le toega ma le porosity o oloa,
6.Labor ma le faʻasaoina o tau e ala i le faʻapipiʻiina ma le tausiga lelei.

Fa'aogaina o le Sima Alumina Maualuga Maualuga
O le sima alumina maualuga e masani ona faʻaaogaina i manaʻoga faʻapitoa o le fausiaina o faʻalavelave faʻafuaseʻi, faʻalavelave faʻafuaseʻi, faʻalavelave sulfate ma le fausiaina o le taumalulu. Ma maualuga alumina refractory sima e masani ona faʻaaogaina i fuafuaga faʻanatinati poloketi, e pei o le puipuiga o le mamafa, auala ma galuega faʻapitoa faʻaleleia. Fa'apena fo'i sima afi alumina maualuga fa'aaogaina i le nofoaga nei:
- Fausiaina o le sulfate corrosion teteʻe ma le maualuga o le vevela faʻamaoniga,
- Faʻaaogaina i le toe faʻaleleia vave, taofi le leaka, tetee atu i osofaʻiga sulfate,
- Fa'apipi'i lelei mo mea fa'afu e pei o le sima fa'afu, fa'afefiloi fa'ato'aga, fa'afefiloi ramming, fa'afefiloi fana ma piliki maamora fa'atagata,
- Fa'aaogaina e fai ma fa'apipi'i sima,
- Fa'aaogaina mo le fa'amaufa'ailogaina o oloa fa'alavalava ma le sima fa'amama,
- Faʻaaogaina i vailaʻau kemisi, alamanuia metallurgical, mea faufale.
Faumea Sima Alumina Maualuga Maualuga mai le Falegaosimea a le RS Refractory
RS refractory factory o se fa'apolofesa maualuga alumina refractory sima fa'atūina i le amataga o le 90s o le luasefulu seneturi. RS refractory fale gaosi faʻapitoa i sima alumina maualuga mo le silia ma le 20 tausaga. afai e iai sau mana'oga o sima fa'amaualuga alumina maualuga, po'o iai ni fesili i luga ole zircon mulite refractory bricabout fa'ailoga fa'aletino ma vaila'au, fa'amolemole fa'afeso'ota'i i matou e leai se totogi. ma le Rs refractory factory e avea o se tagata gaosi piliki refractory zircon mulite faʻapolofesa i Saina, ei ai nisi tulaga faʻatauvaʻa e pei ona taua i lalo:
- Tau Faatauva: Fa'atauva oloa i lau maketi,
- Tele Aafiaga: Puipuia ta'e ma mimilo i piliki,
- Fa'ailoga Eseese: Fa'asao totogifuapauina mo oe,
- Pulea lelei: Faʻafeiloaʻi manaoga o tagata faʻatau,
- Fa'atauga tetele: Fa'amautinoa le vave tu'uina atu,
