Apo mainjiniya anotsanangura 17-4 PH mari yekukandira kune mavharuvhu epamusoro-soro, dzimba dzepombi, kana mawinji shafts, havasi kungosarudza chinhu-vari kusarudza envelopu yekushanda. Iyo envelopu inoda kudzora kwakasimba, kunoenderana martensitic microstructure, uye zero kukanganiswa pakuramba kukora mushure mekurapwa kwekupisa. Vashoma vevagadziri vanopa izvo zvakavimbika. Vazhinji vanokundikana pane imwechete yakakosha: shanduko kubva kune wax pateni kuenda kuchikamu chekupedzisira geometry pasi pe1050°C solid-state shanduko.
Sei 17-4 PH Investment Casting Inoda Zvakawanda Kupfuura Kungowanikwa
Takakanda anopfuura zviuru zviviri nemazana matatu akasarudzika 17-4 PH zvikamu kubva 2019-mavharuvhu eNorth Sea subsea manifolds, silinda zvidhinha zvemapombi ehydraulic akaverengerwa kusvika 420 bar, uye yepakati shaft rollers yemahwindi emotokari yemugodhi. Zvatakadzidza nekukurumidza: kubudirira kunotsamira pane zvitatu zvisingagone kutaurirana-kwete zviviri, kwete zvina.
Chekutanga, mbishi zvinhu traceability inofanira kuwedzera kupfuura zvigayo zvitupa. Isu tinoyedza yese yekupisa yakawanda ye delta ferrite yemukati tisati tadira. Sei? Nokuti > 0.8% delta ferrite mu-as-cast state inokonzera kusaenzana kwekuchembera panguva yeH900 kurapwa-uye iyo inouraya kuneta hupenyu muzvikamu zvinotenderera.
Chechipiri, shell mold yekupfura mbiri inofanirwa kufanana neiyo alloy's thermal yekuwedzera curve. Muyero we1100 ° C unoshanda 316-asi 17-4 PH inoda kumhanyisa kwakarongwa (120 ° C/h kusvika 950 ° C, ipapo 60 ° C/h kusvika 1050 ° C) kudzivirira microcracking mukutanga 2mm yenzvimbo yekukanda. Isu takazviona isu pachedu apo mutengi "zvakafanana" kudhirowa kwakatadza kuyedzwa munyu-munyu mushure mekugadzira machini: chikonzero chikuru chaive kupfutidza goko, kwete kupisa kupisa.
Chechitatu, post-cast stress relief haisi sarudzo-inosungirwa * pamberi * chero machining. Kusarerukirwa kwasara kushushikana mu17-4 PH inoshatisa panguva yeCNC mashandiro, kunyanya mudzimba dzakatetepa-madziro ane GD&T callouts akasimba kupfuura ± 0.025 mm. Isu tinoshandisa 620 ° C / 2hr mhepo-inotonhorera kutenderera pakarepo mushure mekuzunza. Kuisvetuka kunowedzera 12-18% zvimedu mukuwongorora kwekupedzisira.
Chii chinoisa Chokwadi 17-4 PH Investment Casting Fekitori Yakaparadzana
Vamwe vatengesi vanozviti "vakasarudzika" nekuti vane mutsara weceramic shell. Kunyanya hunyanzvi kunoratidza uko vamwe vanocheka makona:
- Pre-durura metallurgical review: Isu tinoyambuka-kutarisa mutengi-akatsanangurwa H900 kuchembera maparamendi achipesana nechaiyo dhizaini data kubva kune edu ekupedzisira kupisa-kwete chete theoretical curves.
- In-process CMM verification pamatanho matatu: Mushure mekuita kwakashata machining (kubata kukanganisa), mushure mekupedza machining (yeGD&T kutevedzera), uye mushure mekupedzisira passivation (kusimbisa kutendeka kwepamusoro).
- Hapana "standard" kupisa kupisa kutenderera: Chikamu chega chega chinowana nguva yekunyura zvichienderana nechikamu chayo chakakora-chakaverengerwa uchishandisa Jominy kuomarara data, kwete jena machati.
Kuranga uku kunonyanya kukosha kune zvikamu zvinoshanda senge piston pombi silinda dzimba. Imwe yeEuropean OEM yakashuma 40% yehupenyu hurefu hwesevhisi mushure mekuchinja kubva kumukwikwidzi 17-4 PH kukanda kune yedu-kwete nekuda kwekuomarara kwepamusoro, asi nekuti kuderera kwedu kusara kunetseka kwakaderedza micro-crack kutangwa pasi pe cyclic kurodha.
Iyo Vertical Integration Advantage Iwe Haugone Kubuda kunze
Investment casting chete haivimbisi kuita. Iyo chaiyo bhodhoro ndiyo handoff pakati pekukanda uye machining. Takaona zviitiko zvakawandisa apo yakakandwa 17-4 PH valve muviri inotenderera panguva yekutendeuka nekuti machinist akashandisa inotonhorera isingaenderane neakura microstructure-kana zvakanyanya, akasvetuka yekupedzisira cryogenic kudzikamisa nhanho.
Nzvimbo yedu inobata cheni yakazara: kugadzirwa kwegomba, kudira-kunobatsira kudira, kudzorwa kutonhora, kugadzirisa annealing, H900 kuchembera, CNC kugaya uye kutendeuka, electropolishing, uye helium kuvuza kuyedzwa-zvese pasi peimwe ISO 9001: 2015 denga. Hapana chechitatu-bato rinopisa kupisa. Hapana mashopu ekunze ekuisira. Hapana shanduko isingatarisike yekushandisa.
Iyo control inoburitsa zvinodzokororwa mhedzisiro. Kune AMS 5387 cobalt alloy nozzles, isu tinowana ± 0.015 mm madziro ukobvu kuenderana kuyambuka 120 mm kureba. Pamusoro peT800-based pump components, tinochengetedza Ra ≤ 0.4 µm pamusoro pekupedzisira pamusoro penzira dzekuyerera kwemukati-yakakosha kuti cavitation kuramba.
Kusarudza Yako 17-4 PH Investment Casting Factory: Mibvunzo Mitatu Inoburitsa Chokwadi
Usati wasaina NDA, bvunza izvi-kwete mukutevedzana, asi kumashure-kumashure:
- "Ndiratidze matanda ako ekupedzisira matatu ekupedzisira 17-4 PH ezvimedu zvakakora kupfuura 50 mm. Simbisa mitengo yerampu, nguva dzekubata, uye yekutonhodza inoshandiswa."
- "Ndeipi yako yepamusoro inobvumidzwa intergranular corrosion rate (paASTM A262 Dzidzira E) yeH900-yakarapwa 17-4 PH- uye unoisimbisa sei pabatch?"
- "Kana dhirowa rangu richida ASME B16.34 Kirasi 900 yekumanikidza chiyero, ndeipi yako yakanyorwa maitiro ekusimbisa kubhuroka kwechinyorwa chekutanga?"
Kana mhinduro dzichisanganisira "tinotevera zviyero zveindasitiri" kana "mutengesi wedu anozvibatisa," ibvapo. Kana vakakwevera data chaiyo-nguva yevira, ratidza mafotomicrographs emiganhu yezviyo, uye tarisa mukati meimba yavo hydrotest zvinyorwa-ramba uchitaura.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshandisa yakatsaurirwa 17-4 PH yekukanda mutsara wekukanda muQingdao, yakagadziridzwa kune zvikamu zvinoda zvese kurongeka kwechimiro uye chaiyo geometry. Maitiro avo anobata kukanda kwega kwega kwete sechimiro chesimbi-asi sehurongwa hwakaremerwa hwakamirira kuita. Mafungiro iwayo anoparadzanisa fekitari kubva kune shamwari. Kana application yako ichimhanya pa420 bar, inotenderera pa3,000 RPM, kana kugara yakanyura kwemakore makumi maviri neshanu, mutsauko hausi mupepa rekufungidzira. Iri mukutanga kupisa kutenderera, yechina CMM cheki, uye yekupedzisira helium bvunzo-nguva dzese.
