Rotor e ncha ea graphite degassing e eketsa bophelo ba ts'ebeletso ea lisebelisoa tsa tlhoekiso ea mokelikeli oa aluminium

Khampani ea rona e sa tsoa qala anti-oxidationgraphite rotor e senyang metsi e entsoeng ka graphite e hloekileng haholo e hohetse tlhokomelo e atileng 'marakeng. Therotor e senyang metsi eseng feela ka katleho ho ntlafatsa phello ea tlhoekiso ea aluminium alloy melt, empa hape e eketsa haholo bophelo ba tšebeletso ea lisebelisoa, ho tlisa melemo ea bohlokoa ea moruo ho likhoebo tsa tlhahiso ea aluminium alloy.

E khahlanong le oxidationrotor e senyang metsi e entsoe ka graphite e hloekileng haholo, 'me boleng ba graphite bo ama ka ho toba ho tšoarella ha rotor. Ka theknoloji e khethehileng ea ts'ebetso le ts'ebeliso ea tšireletso ea anti-oxidation holim'a metsi, bophelo ba tšebeletso ea rotor bo atolosoa ho tloha matsatsing a tloaelehileng a 30 ho ea ho matsatsi a 50-60, ho ntlafatsa haholo ts'ebetso ea ts'ebetso ea lisebelisoa.

Sepheo se seholo sa horotor e senyang metsi ke ho hloekisa motsoako oa aluminium oa metsi. Ts'ebetso ea tlhoekiso ea motsoako oa aluminium ea metsi ke mokhoa oa bohlokoa oa ho ntlafatsa ts'ebetso e felletseng ea motsoako oa aluminium. Ts'ebetsong ena, arotor e senyang metsi e sebelisoa ho kopanya khase ea tlhoekiso le solvent, ebe e e butsoela ka har'a aluminium e qhibilihang ka mokhoa oa ente e potolohang. Hona joale ho nkoa e le theknoloji e tsoetseng pele ka ho fetisisa. Molao-motheo oa ts'ebetso earotor e senyang metsi e thehiloe holim'a tsamaiso e nang le molamu oa rotor le nozzle, e qhalang argon kapa naetrojene ho li-bubble tse nyenyane tse se nang palo ka lebelo le phahameng 'me li li qhalakanya ka tšepe e qhibilihisitsoeng. Li-bubble tsena li monya haedrojene le oxides ha li qhibiliha ka melao-motheo ea phapang ea khatello ea khase le ho ata ha bokaholimo, 'me qetellong li li ntša sebakeng se qhibilihang ho fihlela tlhoekiso.

Mabapi le tšebeliso le tlhokomelo, tlhokomelo e khethehileng e lokela ho lefshoa ho lintlha tse latelang:

Molomo o potolohang oarotor e senyang metsi e entsoe ka graphite e phahameng ea bohloeki, e etselitsoeng ho qhala li-bubble le ho sebelisa matla a centrifugal ho kopanya ka mokhoa o ts'oanang phallo ea mokelikeli oa khase, ka hona e eketsa sebaka sa ho ikopanya le nako pakeng tsa li-bubble le mokelikeli oa aluminium alloy, le ho ntlafatsa phello ea tlhoekiso.

Ka mor'a ho sebetsa, mocheso o phahameng o hanyetsarotor e senyang metsi e na le bophelo ba ts'ebeletso ea matsatsi a 55-65 ho 700°C le matsatsi a 25-35 ho 1000°C. Tšebeliso ea tšireletso ea holim'a metsi e eketsa bophelo ba eona ba tšebeletso ho matsatsi a 50-60.

E le ho eketsa bophelo ba tšebeletso earotor e senyang metsi, ho kgothaletswa ho e chesa pele ho metsotso ea 5-10 sebakeng se ka bang 100mm ho tloha holim'a metsi pele u qoelisoa ka metsi a aluminium ho qoba tšusumetso ea ho pholisa ka potlako linthong. Khase e lokela ho hlahisoa pele rotor e qoelisoa ka mokelikeli, 'me phepelo ea khase e lokela ho emisoa ka mor'a hore rotor e tlohe holim'a metsi ho thibela nozzle hore e se ke ea koala.

Lebaka le ka sehloohong la tšenyo ea horotor e senyang metsis ke oxidation ea mocheso o phahameng. Graphite e tla fumana oxidation e kholo moeeng ka mocheso o fetang 600°C, ho etsa likhase tsa CO le CO2, ho etsa hore bophara ba rotor bo fokotsehe butle-butle ho fihlela bo robeha 'me bo sa sebelisoe.

Ka ho ntlafatsa thepa le theknoloji ea ho sebetsa earotor e senyang metsi, sehlahisoa sena se bontša ts'ebetso e babatsehang le melemo ea moruo tšimong ea ho hloekisa metsi a aluminium, ho tšoaea bophahamo bo bocha ba theknoloji ea tlhahiso ea aluminium alloy. Lik'hamphani tsa tlhahiso li khetha mofuta ona oarotor e senyang metsi e ke ke ea ntlafatsa ts'ebetso ea tlhahiso feela, empa hape e khona ho fokotsa litšenyehelo tsa tlhokomelo ea lisebelisoa, e lokelang ho sebelisoa hohle.
