Lintlha tsa ts’ebetso ea tlhahiso ea litene tse phahameng tsa alumina

Litene tse phahameng tsa alumina li ka boleloa e le mefuta e fapaneng ea lisebelisoa tsa refractory tse nang le tlhahiso e kholo ka ho fetisisa le sekhahla sa tšebeliso. Leha ts’ebetso ea tlhahiso e ts’oana le ea litene tsa letsopa, ho na le phapang lipakeng tsa maemo a lihlahisoa tse tala le mocheso oa sintering.

Tlhahiso ea litene tse phahameng tsa alumina e qala ho laoloa ho tloha khethong ea lihlahisoa tse tala. Tlas’a maemo a tloaelehileng, bahlahisi ba tla khetha ho boloka thepa ea khale ea khale ka nako e itseng, hobane lisebelisoa tse sa tsoa chesoa li tla ba le litšila tse ling ‘me ha li fokotsehe. Litene tse phahameng tsa alumina tse hlahisoang li tla ba tse Foaming, matheba a matšo, ‘me litšila tsa nako e telele li felisitsoe. Litene tse phahameng tsa alumina tse hlahisoang li tsitsitse haholo ho latela ‘mala oa bokaholimo le boleng ba kahare.

Moemeli ea tlamang ts’ebetsong ea ho laola tlhahiso ea litene tse phahameng tsa alumina hape ke ntho ea bohlokoa ka ho fetisisa. Karolelano ha ea lokela ho ba kholo haholo. Ka mor’a hore lihlahisoa tse tala li khethiloe, li silafatsoa, ​​li granulated, ebe joale ho kenyelletsoa karo-karolelano e utloahalang ea moemeli ea tlamang le phofo. Ho kopanya ha hoa lokela ho ba ka tlase ho metsotso e 10. , Nako ea ho kopanya e khutšoanyane haholo, e tla ama qetello le li-pores tsa setene se phahameng sa alumina se phethiloeng.

Ka mor’a tlhahiso ea litene tse phahameng tsa aluminium li laola lisebelisoa tse tala, ho pshatla, likarolo tsa ts’ebetso, le ho kopanya, li thehoa ke mochine oa khatiso o phahameng. Nakong ea ts’ebetso ea ho theha, tlhokomelo e lokela ho lefshoa ho laola lihamore tse ka holimo. Litene tse phahameng tsa alumina li tla ba le spalling ka hare. Palo ea ho etsa likhatello bakeng sa litene tse phahameng tsa alumina e itšetlehile ka boima ba litene tse phahameng tsa alumina. Ka kakaretso, ho sebelisoa lihamore tse ‘maloa tsa lihamore, tse nang le lihamore tse bobebe le tse boima qalong, li otla ka tlase kapa ho feta. Litene tse phahameng tsa alumina ha li teteane ka ho lekaneng ha li otla hanyenyane, ‘me ho otla ho feta ho bonolo ho phunyeha.

Ka mor’a ho bōptjoa, litene tse phahameng tsa alumina lia hlophisoa ebe li tšeloa ka sebōping sa kotopo. Ka kakaretso, binder e qala ka sintered ho tlatsa li-pores le sinter holim’a likaroloana. Ha mocheso o ntse o phahama, sekhahla le matla lia eketseha. E le ho fumana ts’ebetso e akaretsang ea setene se phahameng sa alumina. Leha ho le joalo, mocheso oa ho chesa o khethoa ke lisebelisoa tse fapaneng tse tala tse sebelisetsoang litene tse phahameng tsa alumina. Ha maemo a aluminium a phahame, mocheso oa sintering o phahame.

Ka mor’a hore litene tse phahameng tsa aluminium li kenngoe ka mocheso o phahameng, lihlahisoa tse phethiloeng lia hlophisoa ebe li kenngoa ka lebokoseng, ebe li phutheloa ebe li romelloa ho mosebedisi. Ka bokhutšoanyane, ts’ebetso ea tlhahiso ea litene tse phahameng tsa alumina ha e le hantle ke ho theha khatello e phahameng le mocheso o phahameng oa sintering. Ke ka tsela ena feela moo lipontšo tsa litene tse phahameng tsa alumina li ka tiisetsoang.
