Ukugubungela i-Flux ye-Aluminiyam ye-Alloy Casting
Iimpawu:
I-powder emhlophe, ubukhulu be-particle <20 mesh, umxholo wamanzi ngaphantsi kwe-0.5%.
Imiyalelo:
I-aluminiyam kunye ne-aluminium alloys ngaphandle kwee-alloys eziphezulu ze-magnesium.
Idosi yereferensi:
Bala kwaye ulinganise ngokwendawo ye0.5-1.0kg/m²aluminiyam etyhidiweyo, bala kwaye ulinganise ngokobunzima be0.2%-0.4%aluminiyam etyhidiweyo.Kwaye kuxhomekeke ekucocekeni kokunyibilika kunye nomswakama emoyeni, nokuba ukwandisa okanye ukunciphisa.
Imiyalelo:
Ialuminiyam ingxubevange fluxukugutyungelwa kokugquma kusetyenziselwaukuthintela i-aluminium oxidation, kubangaphakathiezikoisigqubuthelo,ukunciphisa i-oxidationkwayeilahleko evuthayo.
Xa izinto ezingcolileyo kunye ne-non-metallic inclusions zihlanjululwa yi-ejenti yokugubungela, ifom ye-slag ebusweni i-paste okanye i-liquid, kuxhomekeke kwixabiso le-ejenti yokugubungela eyongeziweyo.
Ukuze kugcinwe umphezulu we-liquid ugubungele ngokupheleleyo, kuyimfuneko yokongeza i-agent yokugubungela amaxesha amaninzi.Kungcono ukuyongeza xa isinyithi siqala ukunyibilika.Emva kokuba isinyithi sinyibilike ngokupheleleyo kwaye sigcinwe simile, i-agent egubungelayo kufuneka isetyenziswe ukukhusela ukunyibilika.
Olona ncedo luphambili:
1. Inakoyenza umaleko oxineneyo okhuselayokwayeukunciphisa ukungena kwegesi.
2 Nciphisa ilahleko yentsimbiokubangelwa yi-oxidation yomphezulu wolwelo.
3 Ineengenelo zeindawo yokunyibilika ephakathi, fluidity elungileyokwayeukugubungela kakuhle.
4 Iukusetyenziswa kuncinci, iixabiso liphantsi, kunye nomxholo wensimbi kwi-slag eyenziwe iphantsi kakhulu.
Ukupakishwa kunye nokugcinwa:
Ibhokisi exotshiweyo/ingxowa ephothiweyo:2.5-10kg ngengxowa yangaphakathi, 20-50kg ibhokisi nganye.Ukugcinwa ngokufanelekileyo, nikela ingqalelo kumswakama.
