Precision Lost Wax Investment Die Casting
Incazelo Yomkhiqizo
I-Investment Casting, eyaziwa nangokuthi i-Lost Wax Casting, inqubo yokusakaza enembayo ehlinzeka ngokuguquguquka kwedizayini kanye nezinzuzo zezindleko ezibalulekile.
Inqubo yokutshala imali ihlanganisa ukuthela insimbi encibilikisiwe esikhunjeni esidalwe kusetshenziswa imodeli ye-wax.Uma isikhunta senziwe, imodeli ye-wax iyancibilika futhi ikhishwe.Ama-cores angenalutho angenziwa ngokusebenzisa i-core-proof core evimbela insimbi encibilikisiwe ekugcwaliseni ngokuphelele isikhunta.
I-Investment Casting imvamisa isetshenziselwa ukulingisa okuncane, kodwa ingasetshenziswa ukukhiqiza izingxenye ezinkulu kakhulu.
Ukubekezelela kobukhulu okungu-± 0.003 in./in.zifinyelelwa kalula.Izingxenye ezintekenteke ezinezindonga zizacile njengo-0.025 in. zingafinyelelwa ngokufaka utshalomali.
Amabanga Ezinto Ezivamile zeI-Stainless Steel Casting
I-SS304:Insimbi esetshenziswa kakhulu i-austenite, ingabizwa ngokuthi i-A2 engenasici.
I-SS316:Insimbi yesibili evame kakhulu ye-austenite, ebizwa nangokuthi i-A4 engenasici.I-SS316 isetshenziswa ngokuyinhloko ekwenyukeni kokumelana nokugqwala.
I-SS304L ne-SS316L(i-superaustenitic stainless steel): I-[L” isho ukuthi okuqukethwe kwekhabhoni ku-alloy kungaphansi kuka-0.03%, okunciphisa umphumela wokuzwela obangelwa izinga lokushisa eliphezulu elihilelekile ekushiseleni.Qhathanisa nochungechunge lwe-300, kukhombisa ukumelana okungcono nokuqhekeka kwe-stress-corrosion.
17-4 PH:Imvula evame kakhulu ukwenza lukhuni insimbi engagqwali ye-martensitic, esebenzisa cishe u-17% we-chromium kanye ne-nickel engu-4%.
Ukwelashwa Okungaphezulu kweI-Stainless Steel Castings
I-Shot Blasting: Isetshenziselwa ukususa isikhumba se-oxide esimnyama ngemuva kokusakazwa kwemikhiqizo yensimbi engagqwali.
I-Pickling & Passivation Treatment: I-Pickling iyindlela yokwelapha ngamakhemikhali yokuqeda ukungcola okungaphezulu njengesikhumba se-oxide, ukugqwala, izindawo zokushisela, njll.Futhi i-passivation yinqubo eyenza ungqimba olusha oluningi oluvikelayo lwe-chromium, ngaleyo ndlela kuthuthukiswe ikhono le-anti-oxidation lokusakazwa kwensimbi engagqwali.
I-Electropolishing: Isetshenziselwa ukususa ama-burrs amancane futhi ithuthukise ukugqama kokusakazwa kwensimbi engagqwali.
Ukupholisha isibuko: Uhlobo lwendlela yokupholisha indawo engafinyelela indawo ebushelelezi futhi ecwebezelayo njengesiphetho sesibuko.
Ukusetshenziswa kwe-Stainless Steel Castings
Ngezakhiwo eziyingqayizivele zensimbi engagqwali, izimboni zensimbi engagqwali zinikezwa izimboni eziningi, ikakhulukazi lezo ezisezindaweni ezinzima.Ngezansi izinhlelo zokusebenza eziyinhloko zokusakazwa kwensimbi engagqwali
