Isixhobo sokwenza ipowder ye-atomization ye-VIGA
Umgaqo wezixhobo zokuvelisa umgubo we-vacuum atomization:
I-atomization ye-vacuum isebenza ngokunyibilikisa iintsimbi kunye nee-alloys zesinyithi phantsi kweemeko zokhuseleko lwe-vacuum okanye igesi. Isinyithi esinyibilikisiweyo sihamba siye ezantsi nge-crucible egqunyiweyo kunye ne-nozzle yesikhokelo, kwaye i-atomized kwaye iqhekezwe ibe ngamaconsi amaninzi amancinci ngokuhamba kwegesi okunoxinzelelo oluphezulu nge-nozzle. La maconsi amancinci aqina abe ngamasuntswana angqukuva nangaphantsi ngexesha lokubhabha, aze emva koko ahlolwe kwaye ahlulwe ukuze kuveliswe iipowder zesinyithi zobukhulu obahlukeneyo besuntswana.
Itekhnoloji yomgubo wesinyithi yeyona ndlela isetyenziswa kakhulu kwimveliso kumashishini ahlukeneyo okwangoku.
Ii-alloys ezenziwe kusetyenziswa i-powder metallurgy zineendlela ezahlukeneyo zokusebenza, ezifana nee-alloys ze-welding kunye ne-brazing kwishishini le-elektroniki, ii-alloys ze-nickel, i-cobalt, kunye ne-iron-containing high-temperature zeenqwelo-moya, ii-alloys zokugcina i-hydrogen kunye nee-alloys ze-magnetic, kunye nee-alloys ezisebenzayo, ezifana ne-titanium, ezisetyenziswa ekuveliseni iithagethi.
Amanyathelo enkqubo yokuvelisa iipowder zesinyithi aquka ukunyibilikisa, ukutomisa, kunye nokuqinisa iintsimbi ezisebenzayo kunye nee-alloys. Iindlela zokuvelisa umgubo wesinyithi, ezinje ngokunciphisa i-oxide kunye ne-atomization yamanzi, zithintelwe yimigangatho ekhethekileyo yomgangatho wepowder, efana ne-particle geometry, i-particle morphology, kunye nobunyulu beekhemikhali.
I-atomization yegesi engasebenziyo, kunye nokunyibilika kwe-vacuum, yinkqubo ehamba phambili yokwenza umgubo wokuvelisa iipowders ezikumgangatho ophezulu ezihlangabezana nemigangatho ethile yomgangatho.
Ukusetyenziswa komgubo wesinyithi:
Ii-superalloys ezisekelwe kwi-nickel zobunjineli beenqwelo-moya kunye namandla;
Izinto zokudibanisa kunye nezixhobo zokubopha;
Iingubo ezingagugiyo;
Iipowder ze-MIM zezixhobo;
Ukuvelisa okujolise kwishishini le-elektroniki;
Iingubo zokuthintela ukubola kwe-MCRALY.
Iimbonakalo:
1. Amathontsi aqina ngokukhawuleza ngexesha lokwehla, oyisa ukwahlulwahlulwa kwaye oku kuphumela kwisakhiwo esincinci esifanayo.
2. Indlela yokunyibilikisa ingenziwa ngokwezifiso. Iindlela ziquka: ukunyibilikisa i-induction frequency ephakathi kunye ne-crucible, ukunyibilika kwe-frequency ephakathi ngaphandle kwe-crucible, ukunyibilika nge-crucible resistance heating, kunye ne-arc melting.
3. Ukufudumeza izinto ze-alloy kusetyenziswa izixhobo ze-ceramic okanye ze-graphite kuphucula ubunyulu bezinto ngokusebenzisa iindlela zokucoca nokucoca.
4. Ukusetyenziswa kwe-supersonic tight coupling kunye ne-confined gas atomizing nozzle technology kwenza kube lula ukulungiselela ii-micro-powders ezahlukeneyo ze-alloy material.
5. Uyilo lwenkqubo yokuhlelwa kweenkanyamba ezinezigaba ezibini kunye nokuqokelela luphucula isivuno sempuphu ecolekileyo kwaye lunciphisa okanye luphelise ukukhutshwa kothuli olucolekileyo.
Ukwakhiwa kweYunithi yokwenza umgubo weVacuum Atomization:
Uyilo oluqhelekileyo lweNkqubo yokwenza iPowder yeVacuum Atomization (VIGA) luquka isithando somlilo esinyibilikisa i-vacuum induction (VIM), apho i-alloy inyibilikiswa khona, icocwe, kwaye ikhutshwe igesi. Isinyithi esinyibilikisiweyo esicociweyo sigalelwa kwinkqubo yepayipi yejethi nge-tundish eshushu, apho ukuhamba okunyibilikisiweyo kusasazeka ngokuhamba kwegesi engenaxinzelelo oluphezulu. Umgubo wesinyithi ophumayo uyaqina ngaphakathi kwinqaba ye-atomizing, ebekwe ngqo ngaphantsi kwemilomo ye-atomizing. Umxube we-powder-gas uhanjiswa ngepayipi yokuhambisa ukuya kwi-cyclone separator, apho ii-powders ezirhabaxa nezicolekileyo zahlulwe kwi-atomizing gas. Umgubo wesinyithi uqokelelwa kwisikhongozeli esivaliweyo esisezantsi kwe-cyclone separator.
Olu luhlu luqala kwibanga lelebhu (umthamo we-crucible we-10-25 kg), umgangatho wemveliso ophakathi (umthamo we-crucible we-25-200 kg) ukuya kwiinkqubo zemveliso ezinkulu (umthamo we-crucible we-200-500 kg).
Izixhobo ezenzelwe wena ziyafumaneka xa uzicela.
