Chipangizo chopangira ufa wa VIGA Vacuum atomization
Mfundo ya zipangizo zopangira ufa wa vacuum atomization:
Kutulutsa mpweya m'malo otayira mpweya kumagwira ntchito posungunula zitsulo ndi zitsulo zotayira mpweya pansi pa mikhalidwe yoteteza mpweya kapena mpweya. Chitsulo chosungunukacho chimatsikira pansi kudzera mu chotenthetsera chotenthetsera mpweya ndi nozzle yotsogolera, ndipo chimapangidwa ndi atomu ndikusweka kukhala madontho ambiri abwino ndi mpweya wothamanga kwambiri kudzera mu nozzle. Madontho abwinowa amauma kukhala tinthu tozungulira ndi tating'onoting'ono panthawi youluka, zomwe zimafufuzidwa ndikulekanitsidwa kuti zipange ufa wachitsulo wa tinthu tating'onoting'ono tosiyanasiyana.
Ukadaulo wa ufa wachitsulo ndi njira yogwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana.
Ma alloy opangidwa pogwiritsa ntchito ufa wa metallurgy ali ndi ntchito zosiyanasiyana, monga ma alloy owetera ndi opaka magetsi m'makampani amagetsi, ma alloy okhala ndi nickel, cobalt, ndi chitsulo okhala ndi kutentha kwambiri pa ndege, ma alloy osungira haidrojeni ndi ma alloy a maginito, ndi ma alloy ogwira ntchito, monga titaniyamu, omwe amagwiritsidwa ntchito popanga zinthu zotayira.
Njira zopangira ufa wachitsulo zimaphatikizapo kusungunula, kuyika atomu, ndi kulimbitsa zitsulo ndi ma alloys ogwira ntchito. Njira zopangira ufa wachitsulo, monga kuchepetsa okosijeni ndi kuyika atomu yamadzi, zimaletsedwa ndi miyezo yapadera yaubwino wa ufa, monga mawonekedwe a tinthu tating'onoting'ono, mawonekedwe a tinthu tating'onoting'ono, ndi kuyera kwa mankhwala.
Kutulutsa mpweya wopanda mpweya, kuphatikiza ndi kusungunuka kwa vacuum, ndi njira yotsogola yopangira ufa popanga ufa wapamwamba womwe umakwaniritsa miyezo inayake yapamwamba.
Kugwiritsa ntchito ufa wachitsulo:
Ma superalloy ochokera ku nickel aukadaulo wa ndege ndi mphamvu;
Zipangizo zosungunulira ndi zomangira;
Zophimba zosatha kuvala;
Ufa wa MIM wa zigawo;
Kupanga zinthu zamagetsi mopanda cholinga;
Zophimba zotsutsana ndi okosijeni za MCRALY.
Mawonekedwe:
1. Madontho amauma mofulumira akamatsika, zomwe zimapangitsa kuti pakhale kusiyana kwa madontho ndipo zimapangitsa kuti pakhale kapangidwe kake kameneka.
2. Njira yosungunula ikhoza kusinthidwa. Njira zake ndi monga: kusungunula kwapakati-frequency ndi crucible, kusungunula kwapakati-high frequency popanda crucible, kusungunula ndi crucible resistance heating, ndi arc melting.
3. Kutentha kwapakati kwa zinthu zopangidwa ndi alloy pogwiritsa ntchito zida za ceramic kapena graphite kumathandizira kuti zinthuzo zikhale zoyera bwino kudzera mu njira zoyeretsera ndi kuyeretsa.
4. Kugwiritsa ntchito ukadaulo wolumikizira mwamphamvu wa supersonic ndi ukadaulo wotseka mpweya wa atomizing nozzle kumathandiza kukonzekera ufa wosiyanasiyana wa alloy.
5. Kapangidwe ka njira yosonkhanitsira mphepo yamkuntho yokhala ndi magawo awiri kumawonjezera kuchuluka kwa ufa wabwino komanso kuchepetsa kapena kuchotsa mpweya woipa wa fumbi.
Kapangidwe ka Chida Chopangira Ufa wa Vacuum Atomization:
Kapangidwe kabwino ka Vacuum Atomization Powder Making System (VIGA) kamaphatikizapo ng'anjo yosungunula mpweya (VIM), momwe alloy imasungunuka, kuyengedwa, ndi kuchotsedwa mpweya. Chitsulo chosungunuka choyengedwa chimathiridwa mu dongosolo la mapaipi a jet kudzera mu tundish yotenthedwa, komwe madzi osungunuka amafalikira ndi mpweya woipa kwambiri. Ufa wachitsulo womwe umatuluka umauma mkati mwa nsanja ya atomizing, yomwe ili pansi pa nozzles za atomizing. Kusakaniza kwa ufa ndi mpweya kumatumizidwa kudzera mu chitoliro chotumizira kupita ku cholekanitsa mphepo yamkuntho, komwe ufa wosalala ndi wosalala umalekanitsidwa ndi mpweya wa atomizing. Ufa wachitsulo umasonkhanitsidwa mu chidebe chotsekedwa chomwe chili pansi pa cholekanitsa mphepo yamkuntho.
Kuchulukaku kumayambira pa mulingo wa labotale (mphamvu ya crucible ya 10-25 kg), mulingo wapakati wopanga (mphamvu ya crucible ya 25-200 kg) mpaka makina akuluakulu opangira (mphamvu ya crucible ya 200-500 kg).
Zipangizo zopangidwa mwamakonda zimapezeka mukapempha.
