Puupuu Alumina Piliki Refractory mo le ogaumu Alamanuia
Vaega
O piliki alumina e iai ni uiga fa'apitoa:
1. **Insulation Temi maualuga**:O le maualalo o le vevela e avea ai i latou ma insulators sili ona lelei, fa'aitiitia ai le vevela i totonu o si'osi'omaga maualuga.
2. **Mama maualuga**:Faia mai le alumina mama maualuga, o nei piliki e ofoina atu le faʻatinoga sili atu i tulaga ogaoga.
3. **Mamafa**:O le tuʻufaʻatasia o alumina bubbles e faʻaitiitia ai le mamafa atoa, ma faʻafaigofie ai piliki ma faigofie ona taulimaina ma faʻapipiʻi.
4. ** Tete'e Tempera maualuga**:E mafai ona latou tatalia le maualuga tele o le vevela, e masani lava i luga aʻe o le 1800 ° C, e faʻaogaina ai i latou i totonu o ogaumu vevela ma ogaumu.
5. **Tete'e A'a**:E lelei lo latou tete'e atu i osofa'iga fa'ama'i, aemaise lava mai pa'u ma u'amea u'amea.
6. **Fa'alautele Fa'aavela Maulalo**:Ole vaega lea e fesoasoani ile fa'atumauina le fa'amaoni o le fausaga ma fa'aitiitia ai le ono ta'e ile uila vevela.
7. **Malosi Fa'ainisinia**:E ui lava i le mama, latou te ofoina atu le malosi faʻainisinia lelei ma le tumau i lalo o tulaga faʻaogaina.
O mea nei e fa'atupu ai piliki alumina fa'alelei e fa'apitoa ona aoga i alamanuia e pei o metallurgy, ceramics, ma le gaosiga o tioata.
Fa'aoga masani
Fa'aaoga lautele i totonu o alamanuia e pei o metallurgical, refractories, ceramics, petrochemical, tioata, eletise, ma isi. E mafai ona faʻaaogaina e pei o le faʻafefeteina o foliga vevela o le pyrolizer, ogaumu vevela vevela, ogaumu reheating, tunnel kiln, tuleia slab kiln, ogaumu faʻafefe. , ogaumu eletise, ma isi.
