Tlhaloso e Phahameng ea Alumina e ka Lahloang
Alumina castable e phahameng ke mofuta oa alumina castable e hanyetsang e sebelisang thepa e tala ea alumina e phahameng e le li-aggregate le phofo ebe e eketsoa ka moemeli oa ho tlama. Alumina castable e hanyetsang e phahameng e na le matla a phahameng a mechini, e hanyetsa hantle mocheso, e hanyetsa hantle mafome. Alumina castable e hanyetsang e phahameng ke amorphous refractory e nang le motsamao o phahameng, alumina castable e hanyetsang e phahameng e entsoe ka aggregate e hanyetsang, phofo, binder, li-additives, metsi, kapa lintho tse ling tse metsi. Alumina castable e phahameng e ka sebelisoa ka mokhoa oa ho bopa oa ho lahla sebaka, ho thothomela kapa ho thiba, hape preform e ka etsoa e sebelisoa 'me e ka sebelisoa ka mokhoa oa ho lahla empa ea tiea ntle le ho futhumatsa.
Thepa ea Alumina e Phahameng e ka Lahloang
- Matla a phahameng,
- Botsitso ba modumo,
- Ho thibela mocheso hantle,
- Ho hanyetsa asiti,
- Ho mamella mocheso o phahameng,
- Ho hanyetsa ho ts'oaroa ke mocheso hantle,
- Khanyetso e ntle ea slag,
- Ho hanyetsa ho tsofala hantle,
- Ho hanyetsa mafome hantle,
- Kaho e bonolo.
Ts'ebetso ea Tlhahiso ea Mehato e Mehlano ea Alumina Castable e Phahameng
Khetha thepa e tala ea thepa ea ho lahla aluminium e phahameng ho latela foromo.
Bala tekanyo le tekanyo ea motsoako, phofo, binder le tlatsetso ho latela foromo ea thepa e tala, 'me u laole ka tieo likaroloana tsa phofo e kopantsoeng.
Kenya aggregate e boima le phofo ka har'a blender ka bonngoe, ebe u tšela phofo ka har'a aggregate 'me u hlohlelle metsotso e 8-10.
Kenya thepa e tšeloang ka aluminium e hlohlellelitsoeng ka mokotleng o ka nkang tonne, e nang le lintho tse eketsang le sehokelo, ebe u e paka.
Lisebelisoa tse tšetsoeng ka aluminium e ngata li lokela ho bolokoa ka tlung ea polokelo, 'me letsatsi le lokela ho tšoauoa 'me le se ke la ba mongobo ebile le sa keneleng metsi.
Melemo ea ho lahla Alumina e Phahameng
- Ho hanyetsa ho hoholo, Ho hanyetsa ho hoholo tlas'a mojaro,
- Sekhahla se phahameng, masoba a tlase,
- Ho hanyetsa slag hantle le ho hanyetsa ts'enyeho,
- Matla a phahameng le ho hanyetsa ho tsofala,
- Ho hanyetsa hantle tshebetsong ya flake,
- Ho tsitsisa mocheso hantle,
- Ho hanyetsa ho hohla,
- Matla a chesang a matle.

Tšebeliso ea High Alumina Castable
Sesebelisoa sa ho lahla alumina e ngata se hlahisoa ka mor'a hore se hlahisoe tlas'a mocheso o phahameng ka rotary ebe se siloa hore e be phofo. Sehlahisoa sena ke sa ho etsa lisebelisoa tsa ho lahla tse hanyetsang tsa boleng bo holimo, e leng sesebelisoa se ka sebelisoang libakeng tsa mocheso o phahameng liindastering tse kang tšepe, thepa ea kaho, lik'hemik'hale, fektheri ea motlakase. Hape lisebelisoa tsa ho lahla alumina e ngata li ka sebelisoa libakeng tse latelang.
