Tšebeliso e nepahetseng ea thepa ea ka hare ea sebōpi sa induction le mokhoa oa ho haha ​​​​sebōpi.

1. Se hlahisoang mona ke: quartz acid e omeletseng sebōpi lerako lera ramming lintho tse bonahalang (asiti sebōpi lerako la lintho tse bonahalang). Sesebediswa sena ke motsoako o omileng oa ramming o kopantsoeng pele. Litaba tsa binder, anti-cracking agent le stabilizer li lokisitsoe ho latela litlhoko, ‘me mosebelisi a ka li sebelisa ka kotloloho. Tlhokomelo e khethehileng: basebelisi ha baa lumelloa ho eketsa lisebelisoa leha e le life le metsi ha ba sebelisa. Sehlahisoa sena se loketse ho qhibilihisa tšepe e bohlooho, tšepe e tšoeu, tšepe ea carbon, tšepe e phahameng ea gong, tšepe e phahameng ea chromium, tšepe ea alloy, tšepe ea likaroloana, lisebelisoa tsa ho hlatsoa, ​​koporo, aluminium le lisebelisoa tse ling ka sebōping sa induction.

2. Mohaho oa sebōpi, ontong le ts’ebetso ea sintering

Pele o omme-knotting lerako la sebōpi lerako, pele larileng ka mposo ea asbestos lesela ka sebōpi sebopi insuela lera, ‘me ka bowena boemo le compact mong le e mong lera la lintho tse bonahalang nakong rala.

Knotted sebōpi botlaaseng: Botenya ba botlaaseng ba sebōpi bo ka ba 200mm-280mm, ‘me lehlabathe le tlatsoa ka makhetlo a mabeli ho isa ho a mararo ho thibela ho teteana ho sa tšoaneng hohle ha ho etsoa ka letsoho,’ me lerako la sebōpi ka mor’a ho baka le ho chesa ha le teteane. Ka hona, botenya ba fepa bo tlameha ho laoloa ka thata. Ka kakaretso, botenya ba ho tlatsa lehlabathe ha bo fete 100mm / nako le nako, ‘me lerako la sebōpi le laoloa ka hare ho 60mm. Ts’ebetso ea batho ba bangata e arotsoe ka lichifi, batho ba 4-6 ka ho fetoha, metsotso e 30 ka nako e ‘ngoe le e’ ngoe ea ho etsa knotting, ho pota-pota sebōpi Fetola butle ‘me u sebelise ka ho lekana ho qoba ho teteana ho sa tšoaneng.

Ha mafito a ka tlaase ho sebōpi a fihla bophahamong bo hlokahalang, hlobo ea crucible e ka behoa ka ho e senya. Tabeng ena, tlhokomelo e lokela ho nkoa ho etsa bonnete ba hore hlobo ea crucible e tsepamisitse maikutlo le coil, e lokisoe ka holimo le holimo, ‘me sebopeho se haufi ka hohle kamoo ho ka khonehang ho ea tlaase ho sebōpi se hahiloeng. Ka mor’a ho lokisa sebaka sa peripheral clearance hore se lekane, sebelisa lithapo tse tharo tsa lepolanka ho koala, ‘me boima bo bohareng ba hoisting bo hatelloa ho qoba lerako la sebōpi hore le se ke la otla. Ho falla ha lehlabathe la quartz ho etsahala nakong ea ho knotting.

Lerako la sebōpi: Botenya ba lesela le ka hare la lerako la sebōpi ke 90mm-120mm, ho eketsa lisebelisoa tse omeletseng ka li-batches, lesela le tšoana, botenya ba filler ha bo fete 60mm, ‘me knotting ke metsotso e 15 (manual). knotting) ho fihlela e phophoma ka ntlha e ka holimo ea khoele. The crucible hlobo ha e ntšoe ka mor’a hore knotting e phethoe, ‘me e bapala karolo ea ho futhumatsa karabelo nakong ea ho omisa le ho sintering. Haeba u batla ho ntša hlobo ea crucible, koahela lerako le ka ntle la hlobo ea crucible ka likarolo tse 2-3 tsa koranta pele u koala lerako la sebōpi ‘me u le phuthe ka thata ka theipi. Ka mor’a ho pata, lerako la sebōpi le futhumatsoa ho fihlela ho likhato tse 900, ‘me koranta e tsuba. Ntša hlobo ea crucible kapele. Moqomo oa tšepe o bophara ba lisenthimithara tse 10-15 le bophahamo ba molomo oa sebōpi o bataletse ‘me pin ea tšepe e sebelisetsoa ho futhumatsa karabelo nakong ea ho omisa le ho sintering.

Litlhaloso tsa ho baka le ho sintering: e le ho fumana sebopeho sa likarolo tse tharo tsa lerako la lerako la sebōpi, mokhoa oa ho baka le oa sintering o arotsoe ka mekhahlelo e meraro: ela hloko pini ea tšepe le tšepe e nyenyane e kentsoeng ka sebōping nakong ea ho baka le ho sintering. U se ke ua kenya likotoana tse kholo tsa tšepe, tšepe e nchocho kapa e nang le meno.

Mokhahlelo oa ho baka: Chesa hlobo ea crucible ho 900 ° C metsotso e 20 ka tekanyo ea 200 ea ho boloka mocheso bakeng sa metsotso e 20, 300 ho boloka mocheso ka metsotso e 20, le ho boloka mocheso oa 400 metsotso e 20. Sepheo ke ho tlosa ka ho feletseng mongobo lerakong la lerako la sebōpi.

Semi-sintering stage: Boloka mocheso ho 400 metsotso e 20, 500 metsotso e 20, le 600 metsotso e 20. Sekhahla sa ho futhumatsa se tlameha ho laoloa ho thibela mapetsong.

Sethaleng se felletseng sa sintering: mocheso o phahameng oa sintering, sebopeho sa sintered sa crucible ke motheo oa ho ntlafatsa bophelo ba ts’ebeletso ea ona. Mocheso oa sintering o fapane, botenya ba lera la sintering ha le lekane, ‘me bophelo ba tšebeletso bo fokotsehile haholo.

Sebōping sa induction sa 2T, hoo e ka bang lik’hilograma tse 950 tsa lithapo tsa tšepe li kenyelletsoa ho matlafatsa phello ea ho futhumatsa ha coil nakong ea ho baka. Ha ho baka le ho chesa ho ntse ho tsoela pele, matla a motlakase a batlang a tsitsitse a hlahisoa ka phetisetso ea matla a tlase ho sisinya tšepe e qhibilihisitsoeng ho tlatsa sebōpi. Mocheso oa sebōpi o phahamisetsoa ho likhato tse 1700 ho boloka mocheso ka metsotso e 60, e le hore lesela le ka hare la lerako la sebōpi le futhumale ka ho lekana holimo le tlase. Laola ka thata mocheso oa libaka tse tharo tsa phetoho ea lehlabathe la quartz, u khothalletse phetoho e felletseng ea lehlabathe la quartz, ‘me u ntlafatse matla a pele a sintering a lebota la sebōpi.

3. Summary

Bakeng sa bophelo ba lerako la lerako la sebōpi sa sebōpi sa induction, ntle le ho netefatsa hore ho na le lerako la lerako la sebōpi se feletseng le se utloahalang sa marako a mararo, tlhokomelo e boetse e lokela ho lefshoa ts’ebetsong e tloaelehileng. Litloaelo tsa ho baka tsa mahlale le tsa sintering, ts’ebetso e thata ea ts’ebetso, e ka lelefatsa bophelo ba sebōpi.

4. Mekhoa ea ho paka le ea ho boloka

Lipampiri tse ngata-ngata tse thibelang mongobo le filimi e ka hare ea 25kg / mokotla, boloka sebakeng se omileng ho thibela ho kenngoa ha mongobo. Litlhahiso tsa bophelo ba shelf li ntle haholo
