Paunonzwa N08825, kana Alloy 825, pfungwa yekukurumidza inowanzova 'corrosion-resistant nickel-iron-chromium alloy'. Ndiro bhuku. Asi munyika yekutanga uye yekugadzira, iyo label hainyatso kukwenya pamusoro. Nyaya chaiyo haingori mupepa rekufungidzira; iri mukudururwa, kuchekwa, kupisa kwekupisa, uye zvisarudzo zvidiki zvisingaverengeki zvinoparadzanisa chikamu chinobudirira kubva pamurwi wezvirasha zvinodhura. Ndakaona mapurojekiti akawanda achigumburwa nekuibata seimwewo isina tsvina. Hazvisizvo.
Iyo Foundry Floor Reality ine 825
Kukanda N08825 ndiko uko dzidziso inosangana nemoto, chaizvo. Iyo yakakwira nickel yemukati inoipa iyo inoshamisa kuramba kudzikisa acids uye kusagadzikana-corrosion kupaza, asi zvakare inoita kuti ive chikara chegoko kana kuisa mari. The solidification pattern is... finicky. Iwe haugone kungoshandisa iyo yakafanana geting uye yekusimuka sisitimu yaungashandisa kune 316 isina tsvina chikamu uye tariro yezvakanakisa. Iyo shrinkage yakasiyana, iyo fluidity inonzwa yakasiyana. Pakutanga, takanga tine batch yemamwe miviri yevharuvhu yairamba ichiratidza micro-porosity muzvikamu zvakakora. Iyo chemistry yaive yakakwana pane cert, asi chimiro chaive chisina ruzha.
Nyaya yakadzokera kumashure kwekudurura tembiricha uye mold pre-heat. Isu takanga tichiimhanyisa ichitonhorera zvakanyanya, tichiedza kudzikisa kurasikirwa kwesimbi uye oxidation, asi ne825, izvo zvinongoteya magasi uye zvinogadzira shrinkage nyaya. Unoda kupisa kwakakwira zvakakwana kuti urambe uchimhanya wakatetepa, asi kwete zvakanyanya kukwira unopisa zvinhu zvealloying kana kurwisa ganda receramic zvine hukasha. Ihwindo rakamanikana. Shamwari yakadai Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), nemakumi matatu emakore emugoko uye kuisa mari, vanowana izvi. Vanenge vaona kutamba kumwe chete. Chiitiko chavo pamusoro peakakosha alloys zvinoreva kuti vangangove vakagadzira maprotocol ekudira curve uye mold prep chaiyo kune aya nickel-based mamakisi, inova hafu yehondo yakakunda.
Post-cast heat treatment is non-negotiable. As-cast 825 ine carbides uye intermetallics iyo inoparadza yayo corrosion properties. Iwe unoda iyo mhinduro inonamira kutenderedza ° F ichiteverwa nekudzima nekukasira kudzoreredza zvese mumhinduro yakasimba. Svetuka kana kukanganisa chiyero chekudzima, uye chikamu chinogona kupfuura cheki cheki asi chinokundikana mumunda, munzvimbo ine chloride-rich semuenzaniso. Idanho rakakosha rinowedzera mutengo nenguva, uye haugone kucheka makona.
Machining: Kwainoenda Kushandisa Kufa (Kana Usina Kungwarira)
Kana kuikanda kune hunyengeri, kugadzira N08825 ndiko kwaunowana mitsetse yako. Kuidaidza kuti 'gummy' inhema. Haisi kuputika; inoumba aya akareba, ane tambo, akaomeswa swarf anogona kutenderedza zvese nekukanganisa. Iko kushanda-kuoma mwero inoshamisa. Kupinza kushoma zvishoma kana kuchekwa kwakanyanyisa kunongopenya kumusoro, kuchiomesa uye kuita kuti chinopfuura chiwedzere kuoma, zvichitungamira mukutadza kwechishandiso nekukurumidza uye kukuvara kwepasi pechikamu.
Takadzidza zvakaoma pabasa repombi shaft. Uchishandisa akajairwa carbide mamakisi etsvina? Njodzi. Upenyu hwezvishandiso hwakayerwa mumaminitsi, kwete maawa. Kupedzwa kwepamusoro kwakanga kwakashata, uye taigara tichirwisana nokusagadzikana nokuda kwekupisa uye dzvinyiriro. Budiriro iyi yakabva pakuchinjira kumagiredhi akatsaurirwa-akaomarara, anopinza-kukona-kukona carbides ane machira ehunyanzvi, uye zvibatiso zvematurusi zvisina kusimba zvine kuchinjika kushoma. Inotonhorera haisi yekutonhodza chete pano; ndeyekuzora nekupwanya chip icho. High pressure, through-tool coolant inenge yakasungirwa kune chero yakakomba vhoriyamu.
Apa ndipo panobatanidzwa chitoro chesevhisi yakazara. Kambani inobata zvese kukanda uye iyo CNC machining mumba, semasevhisi akatsanangurwa https://www.tsingtaocnc.com, ine zvakanakira zvakasiyana. Vanamachini ikoko havasi kuona mbishi, annealed billet; vari kutarisana nemitambo yavo pachavo. Ivo vanoziva iyo-yakakandwa mamiriro eganda, iyo ingangoita kuoma kusiyanisa, uye vanogona kugadzirisa yavo machining zano kubva kune yekutanga roughing pass. Iyi ruzivo yakavharwa inodzivirira yakawanda yekufungidzira uye kuuraya kwemidziyo kunoitika kana shopu yekugadzira michina ikawana 'bhokisi dema' richikanda kubva kune isingazivikanwe kwainobva.
Iyo Alloy Sarudzo Musungo: Kana 825 Isiri Mhinduro
Heino gomba rakajairwa: kutsanangura N08825 nekuti inonyatso kuzivikanwa 'corrosion-resistant alloy' pane runyorwa, pasina kunyatsoongorora zvakatipoteredza. Yakanakira sulfuric uye phosphoric acid nharaunda, yakanaka kumvura yegungwa. Asi kana uri kubata nekupisa, kunyura ma chlorides kana mamwe oxidizing asidhi musanganiswa, panogona kuve nesarudzo dziri nani senge yakakwira-molybdenum alloys kana kunyange titanium. Ndinoyeuka purojekiti yemakemikari kugadzirisa scrubber apo mutengi akasimbirira pa825 zvichibva pane yekare spec. Ongororo yerukova chairwo rwekuyerera, rwaive nematehwe eferric uye cupric chlorides, yakaratidza kuti taitamba negomba corrosion. Taifanira kusundidzira kumashure ndokukurudzira imwe nzira.
Ichi ndicho chikonzero kugona kwezvinhu kwakakosha. Mutengesi anonyora ruzivo nehuwandu hwe nickel-based alloys uye cobalt-based alloys haisi kungoratidza menyu. Zvinoreva kuti ivo (kana mametallurgists) vangangove vakabatana munhaurirano idzi. Vanogona kutarisa kudhindwa uye kubvunza mibvunzo yakakodzera nezve tembiricha, pH, ion inosvibisa, uye mazinga ekushushikana. Iyo nzira yekubvunzana inoponesa munhu wese kubva mukukundikana kwemunda kudzika mutsara.
Zvinokanganisawo manufacturability. Dzimwe nguva, diki diki kune dhizaini-yakawedzera rupo radius, shanduko yemadziro ukobvu shanduko-inogona kuita kukanda uye machining 825 zvakanyanya nyore pasina kukanganisa basa. Chitoro chinongogadzira zvikamu zvekudhinda hachizopa izvozvo. Imwe iyo injinjiniya maitiro ekugadzira kubva kune zvinhu kumusoro anogona.
Welding uye Kugadzirwa: Iyo Yakavanzika Stress Point
Zvigadzirwa hazviwanzo kungokandwa uye kugadzirwa. Kazhinji dzinoda kusungirirwa kune zvimwe zvimedu, kana kuve nemanozzles. N08825 inoonekwa seine weldable, uye ndizvo, asi 'weldable' hazvireve 'kuregerera'. Iwe unoda inofananidzira simbi yekuzadza (senge INCO-Weld 825 kana yakafanana), uye kudzora kwakasimba pamusoro pekupisa kwemukati uye kupisa kwekuisa. Kupisa kwakanyanya, uye unogona kunayisa iwo macarbides munzvimbo inobatwa nekupisa (HAZ), kugadzira bhendi rakatetepa rezvinhu izvo zvakarasa kusaita ngura uye kuita brittle.
Takagadzira tangi hombe kamwechete, uye mushure mekuongorora hydro, pakatsemuka muHAZ padhuze nemaseji akati wandei. Post-mortem yakaratidza kuti yaive musanganiswa weiyo zvishoma kubva pakuzadza simbi chemistry uye kurega iyo interpass temp ichikwira kumusoro. Iyo weld simbi pachayo yaive yakanaka, asi nzvimbo iri padivi payo yakakanganiswa. Iko kutadza kusinganzwisisike iyo isingaratidzi kusvika yave pasi pekunetsekana kana mubasa. Ikozvino, mutemo wakazara maitiro qualification uye, kune dzakakomba zvikamu, pamwe post-weld kupisa kurapwa kugadzirisa zvakare HAZ, kunyangwe izvo zvisingawanzo shanda pakugadzira kukuru.
Iyi ndiyo imwe nharo yekubatanidzwa kwekugadzira. Kana mutengesi mumwe chete ari kuita kukanda uye kugadzira achibatawo kugadzirwa, ivo varidzi venhoroondo yese yekupisa yechikamu. Vanoziva chaizvo kuti zvinhu zviri mumamiriro ezvinhu akaita sei mucheki asati aibata, inova shanduko huru yakabviswa kubva kuequation.
Kusimbisa Hunhu: Vimba, asi Simbisa Usingaregi
Iine alloy yakadai, mapepa (Certs of Conformity) ndiwo mutsetse wekutanga, kwete mutsetse wekupedzisa. A melt cert inokuudza kuti chemistry yaive paladle chaipo. Izvo hazvikuudze nezve kutendeseka kwekupedzisira kukanda kana mhedzisiro yekugadzira. Positive Material Identification (PMI) pakugamuchira, uye zvakare pachikamu chakapedzwa, inshuwarisi yakachipa. Ndakaona kusangana-up uko giredhi rinotaridzika rakafanana rakashandiswa nekukanganisa.
Kune zvikamu zvakakosha zvebasa, kunyanya zvekuora, iwe kazhinji unoda zvimwe. Izvi zvinogona kusanganisira intergranular corrosion test per ASTM G28 Method A yeHAZ yema welds, kana ferrite content checks. Dhayi inopinda kana radiographic kuyedzwa kwecastings inenge yakapihwa. Mutengo webvunzo idzi unofanirwa kubikwa kubva pakutanga; hazvisi 'zvekuwedzera'. Mutengesi akajaira kushanda neizvi special alloys vachave neaya maprotocol ekuyedza mukufamba kwavo kwakajairwa uye havazopokana nawo. Zvavo website inotaura zvinhu zvakaita seizvi, izvo zvinoreva hurongwa hwemhando yakavakirwa kuzvibata.
Yekupedzisira yekutora? N08825 chinhu chinoshamisa kana chashandiswa nemazvo. Asi kuita kwayo kwakabatana zvisingaite neumhizha hunoshandiswa padanho rega rega-kubva pachoto chekuvakira kusvika kuchitambi chekupedzisira cheQC. Inopa mubayiro hunyanzvi uye inoranga mapfupi. Ndiwo mutsauko chaiwo pakati pechikamu chichangobva kugadzirwa neAlloy 825 uye icho chinonyatsoita seAlloy 825 inofanira.
