I-VIM-HC Vacuum Induction Electromagnetic Levitation Melting

Isingeniso semodeli

Ifanele ukuncibilikisa nokukhipha i-vacuum induction kwezinto ezisebenzayo ezifana ne-titanium, i-zirconium, ama-superconductor, izinto zokugcina i-hydrogen, ama-shape memory alloys, ama-intermetallic alloys kanye nezinto ezishisa kakhulu.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Izicelo:

• Amakhanda ekilabhu yegalofu enziwe nge-titanium;

• Amavalvu ezimoto e-titanium-aluminium, amasondo e-turbocharger ashisayo;

• Izingxenye zesakhiwo kanye nezinjini zemboni yezindiza (i-titanium castings);

• Izinto zokufakelwa zezokwelapha;

• Ukukhiqizwa kwezimpushana zensimbi ezisebenzayo;

• Ama-pomp castings nama-valve enziwe nge-zirconium, asetshenziswa embonini yamakhemikhali kanye nokubhoboza olwandle, njll.

Umgomo wokuncibilika kwe-levitation:

Isithando sokuncibilikisa i-VIM-HC vacuum levitation sibeka insimbi ukuthi incibilikiswe ensimini kagesi eshintshashintshayo enemvamisa ephezulu noma ephakathi eyakhiwe yi-induction coil ngaphansi kwezimo ze-vacuum. I-crucible yensimbi epholile ngamanzi isebenza njenge-"concentrator" yensimu yamagnetic, igxila amandla ensimu yamagnetic ngaphakathi komthamo we-crucible. Lokhu kudala imisinga enamandla ye-eddy eduze kobuso beshaja, ikhulula ukushisa kwe-Joule ukuze kuncibilikiswe ishaja futhi ngesikhathi esifanayo ikhiqize insimu yamandla kaLorentz evuselela (noma i-semi-levitates) futhi ivuselele ukuncibilika.

Ngenxa ye-magnetic levitation, ukuncibilika kuyahlukaniswa kusuka odongeni lwangaphakathi lwe-crucible. Lokhu kushintsha indlela yokushabalalisa ukushisa phakathi kokuncibilika nodonga lwe-crucible kusukela ekuqhutshweni komoya kuya emisebeni, kunciphisa kakhulu izinga lokulahlekelwa ukushisa. Lokhu kuvumela ukuncibilika ukuthi kufinyelele amazinga okushisa aphezulu kakhulu (1500℃–2500℃), okwenza kufaneleke ukuncibilikisa izinsimbi ezinamazinga aphezulu okuncibilika noma ama-alloy azo.

Izinzuzo Zobuchwepheshe:

1. Ukuncibilika
Ukuncibilikisa nokuhlanganisa kabusha;

Ukususa igesi nokucwengisisa;

Ukuncibilika ngaphandle kokuhamba ngesikebhe (ukuncibilika kokumiswa);

Ukuvuselela;

ukuhlanzwa kokunciphisa ukushisa, ukuhlanzwa kokuncibilika kwendawo, kanye nokuhlanzwa kwe-distillation yezinto zensimbi;

2. Ukuphonsa
Ukwakheka kwekristalu okuqondisiwe;

Ukukhula kwekristalu elilodwa;

Ukuphonsa ngokunemba;

3. Ukwakheka Okukhethekile Okulawulwayo
Ukukhipha i-vacuum okuqhubekayo (imigoqo, amapuleti, amashubhu);

Ukufaka i-strip nge-vacuum (ukufaka i-strip);

Ukukhiqizwa kwempuphu ye-vacuum;

Ukuhlukaniswa Komkhiqizo:

* Ukumiswa kweshaja yesithando somlilo ngesikhathi sokuncibilikisa kuvimbela ngempumelelo ukungcola ekuthinteni ishaja nodonga olukwazi ukubethelwa, okwenza lufanelekele ukuthola izinto zensimbi nezingezona ezensimbi ezihlanzekile kakhulu noma ezisabela kakhulu.

* Ukuxutshwa kwe-electromagnetic kokuncibilika kunikeza ukulingana okuhle kakhulu kokushisa kanye namakhemikhali.

* Ukulawulwa kwezinga lokushisa lokuncibilika kanye nokumiswa ngogesi ophakathi noma ophezulu ovela ku-induction coil kufeza ukulawula okuhle kakhulu.

* Izinga lokushisa eliphezulu lokuncibilikisa, elidlula u-2500℃, elikwazi ukuncibilikisa izinsimbi ezifana ne-Cr, Zr, V, Hf, Nb, Mo, kanye ne-Ta.

* Ukushisa kokungenisa kuyindlela yokushisa engathintani, egwema umthelela kanye nokuguquguquka okubangelwa izindlela zokushisa ze-plasma beam noma ze-electron beam ensimbini eboshiwe nencibilikisiwe.

* Ukusebenza okuphelele, okuhlanganisa ukuncibilikisa, ukuphonsa phansi, ukuphonsa okuthambekile, kanye nemisebenzi yokushaja, futhi kungafakelwa ukushaja okuqhubekayo, amadivayisi okudonsa i-billet okuqhubekayo, kanye namadivayisi okusakaza e-centrifugal (ongakukhetha).
