Nickel casting inoburitsa kusarudzika pakupisa, ngura, uye kupfeka-zvichiita kuti ive yakakosha kune hydraulic mavharuvhu, high-pressure pump housings, uye oiri & gasi downhole maturusi. Asi kuwana ruzha, kudzika kwakadzikama nickel castings hakusi kwekungodira simbi yakanyungudutswa muforoma. Takakanda anopfuura zviuru gumi nezviviri nickel alloy zvikamu kubva 2018-kusanganisira AMS 5387 cobalt-nickel pombi zvikamu uye T800-based winch shafts-uye kutadza kwese kwakatidzidzisa chimwe chinhu chaicho. Gwaro iri rinoburitsa izvo zvinoshanda, zvisingaite, uye nei.
Tanga neRight Alloy-uye Zvionese
Nickel casting inotanga nguva refu choto chisati chabaka. Nickel alloys haachinjiki. Uchishandisa IN718 apo mutengi akatsanangura UNS N06625? Icho hachisi chekutsiva-ingozi yekushanda. Takambogamuchira mabhawa akabikwa akanyorwa kuti "Inconel 625" akaedza 0.8% yakaderera mumolybdenum. Kukandwa kwakazoitwa kwakapfuura kuongororwa kwekuona asi kwakakundikana kuyedzwa munyu-spray pamaawa makumi manomwe nemaviri-kwete chiuru. Yechokwadi nickel casting inotanga neyakasimbiswa mill test mishumo (MTRs), yakazara elemental verification kuburikidza neOES spectroscopy, uye kuteedzera kune kupisa nhamba. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., nickel yega yega kana cobalt-nickel batch inopinda mukati meiyo ASTM B446 kana AMS 5708. Hapana kunze. Kana mutengesi wako akasvetuka danho iri, maitiro ako ekukanda atokanganiswa.
Dzora Chiumbwa—Kwete Simbi Chete
Nickel alloys yakanyungudutswa inoda kugadzikana kwekupisa kwakanyanya. Zviumbwa zvejecha zvinotsemuka. Investment shell coatings spall. Isu takaona porosity masumbu achiumbwa kwete kubva mukupinzwa kwegasi-asi kubva kusilica reaction ine nickel oxide pa1,350 ° C. Kugadzirisa? Shandisa zircon-bonded investment shells kune dzakatetepa-walled nickel castings pasi pe5 mm rusvingo ukobvu. Pakukanda jecha, dzivisa ivhu-yakasungirirwa greensand. Chinja ku-no-bake phenolic urethane binders neceramic wash coatings-yakaedzwa kuti inomira> 1,400 ° C pasina micro-cracking. Crucially: preheat molds kusvika 250-350 ° C * uye bata * kwemaminitsi ≥90. Kusvetuka nguva yekunyorova kunokonzeresa kutonhora, kudya kusina kukwana, uye kutonhora kuvharika-kunyanya mumajiometri akaoma sepiston pombi silinda dzimba dzine machani ekutonhorera emukati.
Dzivisa Misungo Matatu Aya—Nguva Yese
- Kudzikisira muripo wekuderera. Nickel alloys inodzikira 2.1-2.5% zvakatevedzana-inenge kaviri grey iron. MaCAD modhi akaiswa pa 2.3% achiri kupa goho +0.12 mm kutsauka pa 300 mm maficha kana kupisa kwekuwedzera kwepateni zvinhu zvisina kuverengerwa.
- Skipping solution annealing usati wagadzira. As-cast nickel zvimiro zvine dendritic segregation uye kusara kunetseka. Kugadzira kusati kwaitwa kupisa kunotungamira kune warpage, chatter, uye nguva isati yakwana kupfeka-kunyangwe nekuiswa kwecarbide. Yese yedu AMS 5387 uye T800 castings inopinda yakazara mhinduro anneal (1,150 ° C / 2 hrs / argon kudzima) pamberi peCNC basa.
- Kufunga kuti "nickel" zvinoreva "kwete-magnetic." Mamwe nickel-copper alloys (semuenzaniso, Monel 400) anochengetedza zvishoma magineti permeability mushure mekukanda. Kana chikumbiro chako chichida MRI-giredhi isiri-magnetism, tsanangura ASTM A479 Giredhi N04400 ne <0.005 max μr—uye simbisa negaussmeter post-heat-treat.
Nei Vertical Integration ichichinja Migumisiro
Kukundikana kwakawanda kwekukanda nickel kunoitika pazvibodzwa zvemaoko: muvambi wekupisa chinopisa, chinopisa chinopisa kune machinist, machinist kusvika pakupedzisa. Isu tinodzora ese mana matanho - mune imwe ISO 9001-yakasimbiswa nzvimbo. Kana mutengi achida kumanikidza mavharuvhu miviri ine ± 0.025 mm ID kushivirira pane 120 mm bhora, isu tinokanda, mhinduro-yakagadziriswa, yakashata-yakatendeuka, yakaomeswa nezera, kupera-kufinhwa, uye kukudzwa-zvose pasi pedenga rimwe. Mhedzisiro? 98.7% yekutanga-pass goho. Enzanisa izvo kune outsourced workflows uko mutengesi wega wega anoshandisa yavo dimensional offsets, thermal nhoroondo, uye pamusoro pekugadzirira nzira. Kusiyana kunobatanidza. Yedu yakatwasuka modhi inobvisa interface kudhiraivha, inoita kuti microstructure ienderere mberi, uye kukiya muGD&T kutevedza kubva pakukanda datum kusvika yekupedzisira ongororo.
Chekupedzisira Cheki: Bvunza Iyi Mibvunzo Mishanu Usati Wakanda
Usati wabvumidza nickel casting quote - kana kusaina padhizaini - simbisa aya mapoinzi mashanu:
- Iyo alloy giredhi inofananidzwa nenharaunda yebasa-kwete chete kusimba kwesimba, asi zvinokambaira kuputika hupenyu pakupisa kwekushanda?
- Zvinhu zvekuumbwa uye preheat profiles zvakanyorwa-hazvifungirwe here?
- Mutengesi anosimbisa zvinhu zvinopinda *uye* anoramba azere nekudziya kwekutsvagisa?
- Ko mhinduro annealing yakarongwa * pamberi * chero machining-uye yakasimbiswa nekuoma uye saizi yezviyo mishumo?
- Kuongororwa kweCMM kunoitwa pazvikamu zvakanyoroveswa, zvakadzikama-zvisina kupisa kubva pamutsetse?
Nickel casting haisi yezvigadzirwa. Icho chibvumirano che metallurgical pakati pekugadzira chinangwa uye chokwadi chemuviri. Kutsauka kwese — kungave mumakemikari, chimiro chemafuta, kana kuyerwa nguva — kunosiya chigunwe mukuita. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tinobata nickel casting semishini-yakakosha mainjiniya, kwete kudira simbi. Nekuti kana pombi yako ichimhanya pa4,000 psi kana vharuvhu yako ichivhara gasi rakavava, hapana muganho we "pedyo zvakakwana."
