Tlhaloso e Khutšoane

Junsheng high-purity magnesium-aluminium spinel system e sebelisa alumina ea bohloeki bo phahameng le bohloeki bo phahameng ba magnesium oxide e le lisebelisoa tse tala, 'me e chesoa ka mocheso o phahameng. Ho ea ka lihlopha tse fapaneng tsa lik'hemik'hale, e arotsoe ka lihlopha tse tharo: SMA-66, SMA-78 le SMA-90. Letoto la lihlahisoa.

TS'ELISO HONA

Likaroloana

• Junsheng high-purity magnesium-aluminium spinel e na le litšobotsi tse latelang:
• High refractory resistance;
• Botsitso bo botle ba mocheso o phahameng oa mocheso;
• Ho hanyetsa ka mokhoa o babatsehang ho corrosion ea slag ea alkaline le ho kenella;
• Botsitso bo botle ba mocheso oa mocheso.

Liminerale tsa spinel li na le tšusumetso ea bohlokoa ho thepa ea mocheso o phahameng oa thepa ea refractory. Ka mohlala, ka lebaka la coefficient e nyenyane ea ho atolosa mocheso oa spinel (α=8.9x10-*/℃ ho 100 ~ 900 ℃), spinel e sebelisoa e le ntho e tlamang (Kapa e bitsoang cementing phase, matrix), magnesia-alumina litene tse nang le periclase. e le karolo e ka sehloohong ea kristale, ha mocheso o fetoha haholo, khatello ea ka hare e hlahisoang e nyenyane, 'me litene ha li bonolo ho senya, kahoo botsitso ba mocheso oa litene bo ka ntlafatsoa (litene tsa magnesia-aluminium Ho tsitsisa mocheso ke 50 ~ 150 linako).

Ho phaella moo, hobane spinel e na le thepa e ntle e kang boima bo phahameng, lik'hemik'hale tse tsitsitseng, le ntlha e phahameng ea ho qhibiliha, 'me e hanyetsana haholo le kutu ka mefuta e fapaneng ea ho qhibiliha ha mocheso o phahameng, ho ba teng ha liminerale tsa spinel lihlahisoa ho ntlafalitse ts'ebetso e phahameng ea mocheso. sehlahisoa.

Lebaka le ka sehloohong le etsang hore mocheso o phahameng oa mocheso o nolofatsang oa litene tsa magnesia-aluminium (ntlha ea ho qala ha e ka tlase ho 1550-1580 ℃) e phahame ho feta ea litene tsa magnesia (ntlha ea ho qala e ka tlase ho 1550 ℃) ke hore sebopeho sa matrix se fapane. .

Ho akaretsa, li-spinels ke lisebelisoa tse babatsehang mabapi le ntlha ea ho qhibiliha, ho atolosoa ha mocheso, ho thatafala, joalo-joalo, tse nang le lik'hemik'hale tse batlang li tsitsitse, ho hanyetsa ka matla ho khoholeha ha slag ea alkaline, le ho hanyetsa khoholeho ea tšepe e qhibilihisitsoeng .Papiso ea thepa ea spinel le li-oxide tse ling. .

Litaba tsa Motheo

Junsheng high-purity magnesia-aluminium spinel e na le litšila tse tlase haholo le ts'ebetso e ntle haholo ea mocheso o phahameng. High-purity spinel e loketse likarolo tse entsoeng esale pele tse kang litene tse phefumolohang, litene tsa setulo, li-ladles, likoahelo tse ka holimo tsa sebōpi sa motlakase, lisebelisoa tsa refractory bakeng sa li-rotary kilns, le lisebelisoa tse refractory bakeng sa li-alloys tse qhibilihisang metsi. lihlahisoa, hammoho le li-spinel-containing shape sets.

Lihlahisoa li ka thusa ho ntlafatsa ho hanyetsa ha slag corrosion ea thepa ea refractory, le ho rarolla bothata ba ho phatloha ha thepa ho bakoang ke ho eketsa lisebelisoa tse tala tsa magnesium.
