Iwe unoona Alloy makumi maviri pane imwe pepa, uye yekutanga pfungwa inowanzo gara-inodzivirira nickel alloy, ichiiputira mukati neHastelloys uye Inconels. Ndipo panotangira kurerutsa. Muchokwadi, maitiro ayo, kunyanya mukugadzira uye machining, anogara mune iyi nuanced, dzimwe nguva inoshungurudza, yepakati. Haisi kukanganwira se 316L, asi hairaire ruremekedzo rwakanyanya seC-276. Ndakaona mapurojekiti achigumburwa nekuita senge.
Chokwadi cheMugadziri: Welding uye Kugadzira Nuances
Kwaunonyatso dzidza nezve alloy iri muchitoro, kwete kubva kudhetateti. NeAlloy 20, maitiro ekushongedza akakosha. Iyo yakagadzikana ne niobium, asi izvo hazviite kuti isadzivirirwe mukunzwa kana iwe usina hanya nekuisa kupisa. Ini ndinoyeuka batch yeakagadzirwa misoro ye phosphoric acid sevhisi uko welds aitaridzika zvakanaka asi akatadza nguva isati yakwana munzvimbo yakakanganiswa nekupisa. Nyaya yacho? Tembiricha yeInterpass yaive yakanyanya. Iyo fungidziro yakati chengetedza iri pasi pe150 ° C, uye vashandi vakarembera, vachifunga kuti nickel alloy inogona kuitora. Hazvaigona. Chiitiko ichocho chakasimbisa mutemo: bata kutenderera kwayo kwekupisa nechirango chimwechete sezvaungaita kune imwe yakawedzera exotic alloy.
Kuumba imwe pfungwa. Iyo ine yakanaka ductility, asi yayo yekushanda-kuomesera mwero wakakosha. Kana iwe uri kuita kutonhora kuumba, iyo yekumanikidza yekushandisa inoda kugadziridzwa ichienzaniswa neyakajairwa austenitic mamakisi. Isu taifanira kuchekazve ma rolls egoko uye chubhu yekupisa kupisa mabheti kamwe nekuti mapfuura ekutanga akanyanya kuomesa, zvichitungamira kuma microcracks panguva yaitevera kucheka. Icho chinhu chinoda kuti iwe uronge chechirimo uye nekuwedzera simba mushure mega ega deformation nhanho.
Apa ndipo panenge pachikosha chiitiko chemuvambi. Shamwari yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore ekukandira nekugadzira, kazhinji vane maparameter aya akadanwa mukati. Investment casting maitiro ane alloys seizvi, kudzora chiyero chekusimba uye mushure-kukanda kupisa kurapwa hakugone kutaurirana kuti uwane kwakaringana carbide kugovera uye kudzivirira yemuno corrosion kick-off point.
Machining: Iyo Yakatetepa Balance yeTough uye Gummy
Kana iwe uchingogadzira 304 kana kunyange duplex simbi, Alloy 20 inonzwa zvakasiyana. Hachisi chinhu chakaomesesa kunze uko, asi chinoshingirira. Haipwanyi chipu zvakachena; inowanzoita tambo yakareba, ine tambo inogona kukanganisa kana ikasagadziriswa. Kiyi yakapinza, yakanaka-rake tooling uye inowirirana, ine mwero madyisa uye kumhanya. Aggressive cuts inotungamira kune yakavakirwa-kumusoro kumucheto uye kushomeka kwepamusoro kupera.
Takadzidza izvi pabasa repombi shaft. Kushandisa iwo maparamendi akafanana neayo 17-4PH isina tsvina kwakakonzera kukurumidza kupfeka kwechishandiso uye yakarivara yejenari yepamusoro. Kutsigira kumhanya, kuwedzera chikafu zvishoma (counterintuitive, asi inobatsira mukutyoka kwechip), uye kushandisa chinotonhodza chepamusoro-soro kwakaita mutsauko wese. Nyaya yacho ine nzira yekukuudza kana wakanganisa.
Kune zvikamu zvakaoma, apa ndipo pakabatanidzwa CNC machining kugona kunova mukana mukuru. Mutengesi anobata zvese zviri zviviri kukanda uye kupedzisa machining, semasevhisi akatsanangurwa tsngtaocnc.com, inogona kukwidziridza mafambiro ese ebasa. Vanogona kusiya marevisheni emari akakodzera kubva padanho rekukanda, vachinyatsoziva kuti michina yavo ichabata sei macheki ekupedzisira pane iyi alloy chaiyo, vachidzivirira kushushikana kwekuendesa semi-yakapera, yakaomeswa kukanda kune imwe chitoro chemuchina.
Iyo Special Alloy Context uye Kusarudzwa kwezvinhu
Alloy 20 inowanzoiswa pasi pearoyi akakosha, uye ndizvozvo. Asi zvakakosha kuti utsanangure kuti chakakoshera chii. Nzvimbo yayo inotapira ndeye sulfuric acid nharaunda, kunyanya uko ma chlorides aripowo. Ndiko kuenda-kune akawanda emusanganiswa matangi, pombi, uye zvigadziriso mumakemikari kugadzirisa. Zvisinei, ndazviona zvichishandiswa zvisizvo mukutarisira kuramba kwepasi rose. Haisi yakanaka kune yakanyanya oxidizing mamiriro kana hydrofluoric acid, semuenzaniso.
Kuisarudza kunowanzo kudzika kune mutengo-kuita ongororo inopesana nepamusoro-nickel alloys. Mune imwe purojekiti yechirimwa chepakati chemishonga, dhizaini yekutanga yakadana Hastelloy C-22 yereyakita system yese. Ongororo yakaratidza kuti kune chaiyo tembiricha uye kusangana kwe sulfuric acid iripo, Alloy 20 yakanga yakanyanyisa kukwana. Iyo switch yakachengetedza yakakosha mari yemari pasina kukanganisa hupenyu hwesevhisi. Ndiko kukosha kweiyo chaiyo, kwete kunyanya-kuchengetedza, kusarudza zvinhu.
Izvi zvinoenderana neiyo zvinhu portfolio yenyanzvi yakaita seQSY. Basa ravo ne nickel-based alloys uye cobalt-based alloys zvinoreva kuti vanonzwisisa iyi nhanho yekusarudza maitiro. Havasi kungotengesa simbi; ivo vanowanzobatanidzwa mukubvunzana kwekutanga kuti vaone kana Alloy 20 ndiyo yakakodzera, kana kana mamiriro ebasa achida nhanho kuenda kune chimwe chinhu chakasimba, chavanogonawo kupa.
Mafungiro ekukanda: Hunhu uye Ruzivo
Casting Alloy 20, kunyanya kuburikidza ne shell mold casting kana Investment casting nzira QSY inyanzvi, inopa yayo seti yezvinetso. Iyo alloy ine yakanyanya kunyungudika nzvimbo uye chaiyo shrinkage maitiro. Kuti uwane ruzha, kukanda kwakadzika kusununguka kubva kune shrinkage porosity kana misodzi inopisa, gating uye kusimuka system dhizaini yakakosha. Hakusi kudira wokanganwa zvinhu.
Ndakaongorora mitumbi yakakandwa yevharuvhu uko kuonda kwakatanga kubva mukati memukati madiki-shrinkage cavities aisaonekwa paRT. Iyo yekuvakira yakanga yashandisa dhizaini inosimuka inokodzera zvirinani simbi yekabhoni. Kugadzirisa kwaisanganisira kuchinja kune exothermic risers kuti simbi irambe yakanyunguduka kwenguva yakareba uye kukurudzira kusimba kwekwakananga. A foundry's pateni engineering inyanzvi inoedzwa zvakananga pano.
Kubatsira kwekushanda kwenguva refu ndiyo raibhurari yemaitiro akapupurirwa uye maitiro avanovaka. Pazvinhu zvinodzokororwa senge pombi casings kana impellers muAlloy 20, iyi nhoroondo yemaitiro data yakakosha pakuona kuenderana uye kunaka kubva pakudirwa kwekutanga kusvika kune zana.
Mubasa: Iyo Yenguva Yakareba Kurinda
Umboo hwekupedzisira hwechipi nechipi chinosarudzwa chiri mubasa. Alloy 20 zvikamu zvinoda hurongwa hwekutanga hwekuongorora, kunyanya kune welds uye nzvimbo dzepamusoro-soro. Isu takamboteedzera seti yemachubhu ekupisa mukati memakore mashanu. Zvinhu zvevabereki zvaive zvisina kunaka, asi mashoma echubhu-kune-tubesheet welds airatidza zviratidzo zvekurwiswa kushoma kwebanga. Kwakanga kusiri kutadza, asi yakaratidza kuti kunyangwe mubatanidzwa wakasungwa zvakanaka ndiyo inonyanya kutambudzika. Mhinduro yakanga isiri yekushandura alloy, asi kuita yakanangwa yekuongorora protocol kune iwo majoini panguva yekuvhara.
Iyo ine zvakare yakanaka ma mechanical zvivakwa pakudziya kuri pakati nepakati, asi haudi kusunda simba rayo rekukwira. Kune yakakwirira-tembiricha, yakakwirira-kumanikidza sulfuric mitsetse, inogona kunge iri sarudzo isiriyo. Zvekare, ndezvekuziva nzira yayo.
Pakupedzisira, kushanda neAlloy 20 ndeyekuremekedza hunhu hwayo. Icho chinhu chinobatsira zvikuru cheinjiniya chinozadza mukaha wakakomba pakati pesimbi isina tsvina uye premium nickel alloys. Asi kukosha kwayo kunongoonekwa zvizere kana iwe uchibvuma nuances yayo mukugadzira, kugadzira, uye kushandisa. Haisi nhumbi; chishandiso chaicho. Uye sechinhu chero chipi zvacho chakanyatsojeka, kuita kwayo kunoenderana zvakanyanya nehunyanzvi hwevanhu vanotsanangura, kukanda, kugadzira, nekuiisa sezvainoita pane chemistry yealloy pachayo.
