Kunyungudika & Kudurura: Iyo Poindi yekusadzoka
Apa ndipo panoongororwa basa rese rekugadzirira. Yepamusoro-inoshanda alloys senge cobalt-based alloys kana super duplex simbi isina tsvina inonyorwa neQSY, kunyunguduka kudzidzira ndiko kwakakosha. Haisi yekungosvika kune tembiricha ye liquidus. Izvo ndezvekubata nguva, slag control, uye inoshanda degassing kuderedza porosity. Iwe unoda iyo chaiyo yevira mamiriro (kazhinji argon kana vacuum kune reactive alloys) kudzivirira oxidation uye kusanganisa kuumbwa.
Kudira inguva pfupi, yesarudzo. Simbi inofanira kunge iri pakupisa kukuru-kupisa zvakakwana kuzadza mold yose, kunyanya zvikamu zvitete, asi kwete zvakanyanya kupisa zvokuti zvinokonzera simbi-shell reaction kana kukura kwezviyo. Kudira kunofanirwa kuve kwakatsetseka uye kuenderera kudzivirira mhirizhonga inoteya mweya. Ndinoyeuka chimwe chiitiko chine zvakawanda zvakaoma patakanga tine porosity inopfuurira mune imwe nhanho. Takaedza kugadzirisa gating, goko, zvese. Pakupedzisira, takadzikisira chiyero chekudira ne20%. Zvakazoitika kuti kudira kwekukurumidza kwaive kugadzira kuvhuvhuta mugomba iro, kusveta mweya. Kuyerera kunononoka, kwakadzikama kwakagadzirisa. Dzimwe nguva kugadzirisa hakusi yepamusoro-tech; kunongova kucherechedza uye mwoyo murefu.
Solidification chiitiko chekupedzisira chekukanda. Iyo mold dhizaini (masuwo uye mafidhita atakavaka maawa kana mazuva apfuura) ikozvino inofanirwa kushanda. Simbi yacho inofanira kusimba yakananga, kubva kure-kure kumashure kwakananga kunodyisa, iyo inoshanda sedhishi remvura yesimbi yekudyisa shrinkage. Kana izvi zvikasaitika, iwe unowana shrinkage porosity mukati memadziro ekukanda. Simulation yekombuta inobatsira mazuvano, asi hapana chinotsiva chekucheka yekutanga-chinyorwa kukanda kuratidza iyo yekusimbisa pateni. Muedzo unoparadza, asi ndiyo chete nzira yekuve nechokwadi chekuti maitiro ako akanaka.
Kupedzisa & Kusimbisa: Basa Risingaonekwe
