Idivayisi yokwenza i-powder ye-atomization ye-VIGA Vacuum
Isimiso semishini yokukhiqiza i-vacuum atomization powder:
I-atomization ye-vacuum isebenza ngokuncibilikisa izinsimbi kanye nezinsimbi zensimbi ngaphansi kwezimo zokuvikela i-vacuum noma igesi. Insimbi encibilikisiwe igeleza iye phansi nge-crucible evikelwe ngokushisa kanye ne-nozzle eqondisayo, futhi i-atomized futhi ihlukaniswe ibe amaconsi amaningi amahle ngokugeleza kwegesi okunomfutho ophezulu nge-nozzle. La maconsi amancane aqina abe yizinhlayiya eziyindilinga nezingaphansi kwe-spherical ngesikhathi sokundiza, ezibe sezihlolwa futhi zihlukaniswe ukuze kukhiqizwe impuphu yensimbi yobukhulu obuhlukahlukene bezinhlayiya.
Ubuchwepheshe bempuphu yensimbi njengamanje buyindlela yokukhiqiza esetshenziswa kakhulu emikhakheni eyahlukahlukene.
Ama-alloy akhiqizwa kusetshenziswa i-powder metallurgy anezinhlelo zokusebenza eziningi, njenge-welding kanye ne-brazing alloys embonini ye-elekthronikhi, i-nickel, i-cobalt, kanye ne-iron-containing high-temperature alloys zezindiza, ama-alloy okugcina i-hydrogen kanye nama-alloy kazibuthe, kanye nama-alloy asebenzayo, njenge-titanium, asetshenziswa ekukhiqizeni okuqondiwe.
Izinyathelo zenqubo yokukhiqiza izimpushana zensimbi zifaka phakathi ukuncibilikisa, uku-atomize, nokuqinisa izinsimbi ezisebenzayo kanye nama-alloy. Izindlela zokukhiqiza i-metal powder, njengokunciphisa i-oxide kanye ne-water atomization, zinqunyelwe amazinga akhethekile ekhwalithi ye-powder, njenge-particle geometry, i-particle morphology, kanye nobumsulwa bamakhemikhali.
I-atomization yegesi engasebenzi, kuhlanganiswe nokuncibilikisa i-vacuum, inqubo ehamba phambili yokwenza impuphu yokukhiqiza impuphu zezinga eliphezulu ezihlangabezana nezindinganiso ezithile zekhwalithi.
Ukusetshenziswa kwempuphu yensimbi:
Ama-superalloy asekelwe ku-nickel obunjiniyela bezindiza kanye namandla;
Izinto zokubopha kanye nezokubhoboza;
Izembozo ezingagugi;
Ama-MIM powder ezingxenye;
Ukukhiqizwa okuqondiwe embonini ye-elekthronikhi;
Izembozo zokulwa ne-oxidation ze-MCRALY.
Izici:
1. Amaconsi aqina ngokushesha ngesikhathi sokwehla, anqobe ukuhlukaniswa futhi kuholele esakhiweni esincane esifanayo.
2. Indlela yokuncibilikisa ingenziwa ngokwezifiso. Izindlela zifaka: ukuncibilikisa kokungeniswa kwemvamisa ephakathi nendawo nge-crucible, ukuncibilika kwemvamisa ephakathi nendawo ngaphandle kwe-crucible, ukuncibilika ngokushisa kokumelana ne-crucible, kanye nokuncibilika kwe-arc.
3. Ukushisa okujwayelekile okuphakathi kwezinto ezihlanganisiwe kusetshenziswa izitsha zobumba noma ze-graphite kuthuthukisa ubumsulwa bezinto ngokusebenzisa amasu okucwenga nokuhlanza.
4. Ukusetshenziswa kokuxhuma okuqinile kwe-supersonic kanye nobuchwepheshe be-nozzle ye-atomizing yegesi evalekile kwenza kube lula ukulungiselela ama-micro-powder ahlukahlukene e-alloy.
5. Ukuhlelwa kwesistimu yokuqoqa iziphepho ezinezigaba ezimbili kuthuthukisa isivuno sempuphu ecolekile futhi kunciphisa noma kuqede ukukhishwa kothuli olucolekile.
Ukwakheka kweyunithi yokwenza i-Vacuum Atomization Powder:
Umklamo ojwayelekile we-Vacuum Atomization Powder Making System (VIGA) uhlanganisa isithando somlilo esincibilikisa i-vacuum induction melting (VIM), lapho ingxube incibilikiswa khona, icwengisiswe, futhi ikhishwe igesi. Insimbi encibilikisiwe ecwengisisiwe ithululelwa ohlelweni lwepayipi le-jet nge-tundish eshisiwe, lapho ukugeleza okuncibilikisiwe kuhlakazwa khona ukugeleza kwegesi engenamandla okucindezela okuphezulu. Impuphu yensimbi ephumayo iqina ngaphakathi kombhoshongo we-atomizing, otholakala ngqo ngaphansi kwama-nozzles e-atomizing. Ingxube ye-powder-gas idluliselwa ngepayipi lokulethwa iye kusihlukanisi se-cyclone, lapho impuphu eziqinile nezincane zihlukaniswa khona negesi ye-atomizing. Impuphu yensimbi iqoqwa esitsheni esivaliwe esitholakala ngqo ngaphansi kwesihlukanisi se-cyclone.
Ububanzi busukela ebangeni lelabhorethri (umthamo wokucwilisa ongu-10-25 kg), izinga lokukhiqiza eliphakathi (umthamo wokucwilisa ongu-25-200 kg) kuya ezinhlelweni zokukhiqiza ezinkulu (umthamo wokucwilisa ongu-200-500 kg).
Imishini eyenziwe ngokwezifiso iyatholakala uma iceliwe.
