Paunonzwa 'mugadziri wesimbi yekukanda mari,' pfungwa zhinji dzinosvetuka dzakananga kumufananidzo wekare wesimbi inorema, yegrey—mavharo emugodhi, mabhuroko einjini, vanofungirwawo zvavo. Ndiyo yekutanga kusanzwisisa. Muchokwadi, mharadzano ye simbi yakakandwa uye Investment casting nzira, inowanzonzi nzira yakarasika wakisi, inzvimbo inoda imwe mhando yehutsanana. Hazvisi zvekungodira simbi yakanyungudutswa; ndezvekudzora hukasha hwayo mukati meganda receramic kuti uwane geometries jecha rekukanda harigone kubata. Zvitoro zvakawanda zvinoti zvinokwanisa pano, asi musiyano uripo pakati pekutaura uye kugara uchiendesa ndiko kune nyaya chaiyo.
The Material Paradox: Nei Ductile Iron Isiri Yagara iri Mhinduro
Ngatikurukurei sarudzo yezvinhu. A common pitfall inongo tsanangura otomatiki ductile iron kune yese yakaoma Investment casting basa, tichifunga kuti nodular graphite chimiro chinovimbisa kuoma. Zvinowanzoita, asi ndakaona mapurojekiti achiparara nekutarisisa maitiro ekusimbisa shrinkage. Kune matete-madziro, maumbirwo akaoma kunzwisisa-funga yakaoma yevhavhavhavhavha yedzimba ine migero yemukati-yakanyatsodzorwa grey iron (seClass 35 kana 40) dzimwe nguva inogona kuzadza mold yakavimbika, ine ngozi shoma ye micro-shrinkage porosity mumakona akaoma. Sarudzo inotsamira pane iyo chikamu chekushushikana chimiro uye yekutanga gating uye nekukwira kwehunyanzvi.
Takadzidza izvi kuburikidza nekurwadziwa, mwedzi-refu iteration yepombi inofambisa. Mutengi akasimbirira pane ductile iron ye corrosion kuneta kuramba. Iwo matatu ekutanga mabhechi aive neanoramba achidzikira pamidzi yemablade. Mushure mekuongorora kwemetallurgical uye hurukuro dzisingaverengeki, takakurudzira shanduko kune yakakwirira-simba grey iron ine alloying yekuwedzera. Rakanga risiri iro bhuku rekutanga sarudzo, asi rakagadzirisa dambudziko rekudya uye rakasangana nemaitiro ekuita. Mutengi akange asina chokwadi kusvika pakuyedzwa kuneta kwadzoka. Tinodzidzei? Iyo data data ndiyo yekutanga, kwete mepu yekupedzisira.
Apa ndipo apo ruzivo rwemugadziri wenguva refu runobatika. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ine makore ayo 30 akataurwa mukuumbwa, ingadai yakatarisana nemharadzano iyi kakawanda. Portfolio yavo kusanganisira simbi yakakandwa, simbi, uye alloys akakosha anoratidza kuti vakafanirwa kugadzira maprotocol akasiyana emhuri yega yega. Kubata nickel-based alloys inokudzidzisa nezve kudzora kupisa, zvidzidzo zvinonatsiridza nzira yaunosvika nayo tembiricha yekudurura uye kutonhora kwesimbi.
Iyo Maitiro Tightrope: Kubva Patani kuenda kuShell Kudurura
Iyo wakisi patani nhanho inonyengera nyore. For simbi yakakandwa, iyo ine tembiricha yekudira yakakwira kupfuura aruminiyamu asi yakaderera pane mamwe ma superalloys, magadzirirwo ewakisi uye majekiseni paramita anoda kuenzanisa kugadzikana kwedimensional nekubvisa nyore. Iyo pateni inokanganisa zvishoma mudura rechirimo inogona kukanganisa kushivirira kwekupedzisira kwekukanda. Isu takamborasikirwa nekugadzirwa kwevhiki nekuti batch idzva rewakisi rakazvibata zvakasiyana mukunyorova, zvichiita kuti maungano welds pamaitiro akaoma akundikane panguva yekubata.
Ipapo kunouya chivakwa chehoko. Iyo ceramic slurry uye stucco sisitimu yesimbi inoda kumirisana nekuvhunduka kwekupisa uye ferrostatic kudzvanywa pasina buckling kana kugadzira veining. Ini ndinosarudza yakasanganiswa silica-yakavakirwa bhachi rekutanga nekuda kwekugadzikana kwayo kwekupisa, asi yakanyanya brittle. Zvimwe zvitoro zvinopika nehupfu hwezikoni. Hapana resipi yakanakisa yepasirese; iko kuwirirana pakati pekuramba kwecrack, collapsibility post-cast, uye mutengo. Mugadziri akanaka akagonesa izvi kune yavo yakajairika chikamu saizi uye huremu renji.
Iyo dewaxing uye kupfura nhanho yakakosha. Steam autoclave dewaxing inokurumidza, asi kune inorema wax maassemblies, flash kupfura kungave nani kudzivirira kuputika kwegoko. Iyo goko rakadzingwa rinofanirwa kunge riine zero residual kabhoni kana iron yarova, kana kuremara kwepamusoro kunovimbiswa. Iri isuwo rakanyarara, risingaonekwe remhando. Iwe unongoziva iwe wakatadza mushure mekuputika kuputika, ndosaka maitiro ekudzora matanda echoto tembiricha profiles akakosha senge melt chemistry pachayo.
Machining Kubatanidzwa: Iyo Make-kana-Break Handoff
Uyu pamwe ndiwo musiyano mukuru kune wechokwadi mhinduro mupi. A simbi yekukanda mari yekukanda mugadziri iyo inopawo mumba CNC machining, senge QSY inoratidzira pane yavo saiti https://www.tsingtaocnc.com, inobvisa kutemwa nemusoro kukuru. Kanda simbi, kunyanya mamakisi ane yakakwira graphite zvemukati, michina yakasiyana nesimbi. Iyo graphite inoshanda semafuta, asi zvakare inogadzira guruva rinoputika rinopfeka maturusi.
Kuve nezvikwata zvekukanda uye zvekugadzira pasi pedenga rimwe zvinoreva kuti machinist anogona kudzoka zvakananga kune yekutanga. Vanogona kuti, Iyi flange inogara yakakora 0.5mm kune rimwe divi, unogona here kugadzirisa pateni kana kudira kona? Kana kuti, Kuoma kuri mubatch iyi kusiana, kuita kuti hupenyu hwematurusi husatarisike. Iyi yakavharwa-loop mhinduro yakakosha pakuvandudza nguva dzose. Inoshandura hukama hwevatengesi kuita mubatanidzwa.
Ini ndinorangarira giya rekuvaka purojekiti uko as-cast datum nzvimbo dzaive dzakangokwana kuti chucking, asi ekupedzisira mabhora ekupedzisira akagadzirwa. Nekuda kwekuti machining aiitirwa kunze, paive nekukakavadzana nguva dzose pamusoro pekuti kusarongeka kwakange kuri kukanganisa kwekukanda kana dambudziko rekugadzirisa machining. Yaive classic blame game. Kuunza maitiro ese ari maviri mukati anogadzirisa izvo. Mutengo wenzvimbo yekugadzira machining wakakwira, asi mutengo wekukakavadzana kwemhando dzisina kugadziriswa kazhinji unokwira.
Apo Special Alloys Inozivisa Iron Kudzidzira
Izvo zvakakosha kana yakawanikwa senge QSY rondedzero cobalt-based uye nickel-based alloys parutivi simbi yakakandwa. Kushanda neaya ekunze zvinhu zvinomanikidza chirango chakanyanyisa mukudzora kwemaitiro-kunyungudutsa kupisa kwakanyanya, shell preheat, kukurumidza kudurura, post-cast kutonhora munzvimbo inodzivirira. Chirango ichocho chinobuda ropa zvakare mudhipatimendi resimbi. Iyo crucible yekubata maprotocol, iyo tembiricha kuyerwa frequency, kuomarara mukubvisa slag - iwo ese anokwidziridzwa.
Iwe unotanga kushandisa statistical process control (SPC) kune simbi yako inonyungudika kwete nekuti mutengi anoida, asi nekuti uri kutozviita kune aerospace alloy maodha. Iyi mhiri-pollination yezviyero mukana wakavanzika. Iyo simbi yekukanda inogona kusada argon yekuvhara gasi, asi pfungwa yekunyatso nyora zvese zvakasiyana inodzika mutsika yechikwata. Inosimudza pasi kune zvese zvigadzirwa.
Chokwadi cheMakore Anopfuura 30
Kutora semakore makumi matatu, sezvakataurwa musumo yeQSY, haisi mutsara wekutengesa chete. Muchirevo chechinyorwa ichi, zvinoreva kuti vakakunda mabhizini akawanda, vakaona masitadhi achiuya nekuenda, uye vane bhenji rakadzika reruzivo rwakadzikama. Zvinoreva kuti vangangove vaine maitiro ekushandisa akagadziridzwa kagumi nembiri, shanduko yega yega chidzidzo chakadzidzwa. Zvinoreva kuti vangangodira mamirioni emapaundi esimbi, uye vaona hurema hwese hunogona kuratidzwa.
Ichi chiitiko chinoshandura kukurumidza kugadzirisa matambudziko. Imba itsva inogona kuona chikanganiso uye inomhanya kuburikidza nebhuku rekuongorora. Munhu ane ruzivo anogona kutarisa macro-structure, anzwe masara egoko, obva angofungira, semuenzaniso, kusapindirana kwechiyero chekutonhorera pakati pemakombi uye kudhonza zvikamu zve mold. Iyo intuition, yakazvarwa nekudzokorora, inochengetedza mutengi nguva nemari. Ndiyo asset isingaverengeki.
Pakupedzisira, kusarudza a simbi yekukanda mari yekukanda mugadziri ndeyekuvimba nekutonga kwavo semidziyo yavo. Izvo ndezvekutsvaga mudiwa anonzwisisa kuti mutsara uyu unobatanidza mutsara wezvisarudzo zvakapfava, kubva pakusarudza alloy uye patani dhizaini kuenda kune shell chemistry uye post-cast processing. Chinangwa hachisi chikamu chinosangana nezvakadhindwa; icho chikamu chinoita zvakavimbika, batch after batch, ine shoma yemutambo pakati. Ndiko kubuda chaiko kwekuvhiya kwakapfava.
