nikel

Nickel casting itanga imbaraga zidasanzwe zo kurwanya ubushyuhe, kwangirika, no kwambara - bigatuma iba ingenzi kubibaya bya hydraulic, amazu ya pompe yumuvuduko mwinshi, hamwe nibikoresho bya peteroli na gaze. Ariko kugera kumajwi, nikel ihagaze neza nikel ntago ari ugusuka ibyuma bishongeshejwe mubibumbano. Twataye ibice birenga 12.000 bya nikel alloy kuva muri 2018-harimo AMS 5387 cobalt-nikel pompe hamwe na T800 ishingiye kuri winch shaft - kandi gutsindwa kwatwigishije ikintu cyuzuye. Aka gatabo kagaragaza icyakora, ibitagenda, n'impamvu.

Tangira hamwe na Alloy iburyo - kandi ubigenzure

Nickel casting itangira kera mbere yuko itanura ryaka. Amavuta ya Nickel ntashobora guhinduka. Ukoresheje IN718 aho umukiriya yerekanye UNS N06625? Ibyo ntabwo ari ugusimbuza-ni ingaruka zikorwa. Twigeze kwakira utubari mbisi twanditseho "Inconel 625" twapimye 0.8% munsi ya molybdenum. Ibisubizo byavuyemo byatsinze igenzura ariko birananirana kugerageza umunyu mumasaha 72 - ntabwo 1.000. Nikeli yukuri itangirana na raporo yikizamini cyemewe (MTRs), igenzura ryuzuye binyuze muri OES spectroscopy, hamwe nubushakashatsi bwumubare. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri nikel cyangwa cobalt-nikel ikorerwa ibikoresho byinjira kuri ASTM B446 cyangwa AMS 5708. Niba uwaguhaye isoko asimbutse iyi ntambwe, inzira yawe yo gukina yamaze guhungabana.

Igenzura ibishushanyo - Ntabwo ari ibyuma gusa

Nikel yashongeshejwe isaba ubushyuhe bukabije bwumuriro. Ibishanga byumucanga. Igishoro cyo gushora ibicuruzwa. Twabonye amatsinda ya porosity atavuye mu kwinjiza gaze-ahubwo yaturutse kuri silika reaction hamwe na nikel oxyde ya nikel kuri 1,350 ° C. Gukosora? Koresha zircon ihujwe nigishoro cyibishishwa bya nikel yoroheje munsi ya mm 5 z'ubugari. Kumucanga, irinde icyatsi kibisi kibisi. Hindura kuri no-guteka fenolike urethane ihuza hamwe na ceramic yogeje-yipimishije kwihanganira> 1,400 ° C idafite micro-crack. Byibanze: shyushya ibishushanyo kugeza kuri 250–350 ° C * hanyuma ufate * muminota 90. Gusiba igihe cyo gushiramo bitera gukonja, kugaburira kutuzuye, no gufunga ubukonje - cyane cyane muri geometrike igoye nka pisitori ya pompe ya pisitori ifite inzu yo gukonjesha imbere.

Irinde iyi mitego itatu-Igihe cyose

• Gupfobya indishyi zo kugabanuka. Nickel alloys igabanuka 2.1-2,5% kumurongo - hafi icyuma cyikubye kabiri. Moderi ya CAD yapimye kuri 2,3% iracyatanga + 0,12 mm gutandukana kuri 300 mm biranga niba kwagura ubushyuhe bwibikoresho byerekana bidakorewe. Dukoresha laser-scaneri yo kwemeza mbere yo gusohora ibikoresho.
• Gusiba igisubizo annealing mbere yo gutunganya. As-cast nikel yubatswe irimo dendritic ivangura hamwe nibibazo bisigaye. Gukora mbere yo kuvura ubushyuhe biganisha ku rupapuro, kuganira, no kwambara ibikoresho bidashyitse - ndetse no gushyiramo karbide. Abakinnyi bacu bose AMS 5387 na T800 bahura nibisubizo byuzuye (1,150 ° C / 2h / kuzimya argon) mbere yuko CNC ikora.
• Dufate ko "nikel" bisobanura "non-magnetique." Nikel-umuringa zimwe zivanze (urugero, Monel 400) zigumana imbaraga za magneti nkeya nyuma yo gutera. Niba gusaba kwawe bisaba MRI-urwego rutari magnetisme, vuga ASTM A479 Icyiciro N04400 hamwe <0.005 max μr-hanyuma ugenzure hamwe na gaussmeter nyuma yubushyuhe-buvura.

Impamvu Kwishyira hamwe Guhindura Ibisubizo

Kunanirwa kwa nikel kwinshi bibera kumwanya wa handoff: uruganda rwogukoresha ubushyuhe, kuvura ubushyuhe kumashini, imashini kugeza kurangiza. Tugenzura ibyiciro bine byose - muri ISO 9001 yemewe. Iyo umukiriya akeneye imibiri ya valve ifite ± 0.025 mm kwihanganira indangamuntu kuri bore ya mm 120, twarashizeho, igisubizo-gifatanye, gihindagurika, imyaka-ikomeye, irarambiranye, kandi yubahwa - byose munsi yinzu. Igisubizo? 98.7% umusaruro-wambere. Gereranya ibyo kumurongo woherejwe hanze aho buri mucuruzi akoresha ibipimo bye bwite, amateka yubushyuhe, hamwe nuburyo bwo gutegura hejuru. Ibihinduka. Moderi yacu ihagaritse ikuraho interineti, ikomeza microstructure ikomeza, hamwe nugufunga muri GD&T kubahiriza kuva castum kugeza raporo yanyuma yubugenzuzi.

Igenzura rya nyuma: Baza ibi bibazo bitanu mbere yo gukina

Mbere yo kwemeza amagambo yatanzwe na nikel - cyangwa gusinya ku gishushanyo - genzura izi ngingo eshanu:

1. Urwego rwa alloy rwaba ruhuye nibidukikije bya serivisi - ntabwo ari imbaraga zingana gusa, ahubwo ni ubuzima bwangirika kubushyuhe bwo gukora?
2. Ese ibikoresho bibumbabumbwe hamwe n'ibishushanyo mbonera byanditse - ntibifatwa?
3. Utanga isoko yemeza ibikoresho byinjira * kandi * agumana ubushyuhe bwuzuye?
4. Ese igisubizo annealing giteganijwe * mbere * yo gutunganya - kandi byemejwe nuburemere hamwe na raporo yubunini?
5. Ubugenzuzi bwa CMM bukorwa kubice bikonje, bihamye - ntibishyushye kumurongo?

Nickel casting ntabwo aribikorwa byibicuruzwa. Namasezerano ya metallurgical hagati yubushake bwo gushushanya nukuri kugaragara. Gutandukana kwose - haba muri chimie, imiterere yubushyuhe, cyangwa igihe cyo gupima - gisiga igikumwe mubikorwa. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata gutora nikel nk'ubuhanga bukomeye, ntabwo ari ugusuka ibyuma. Kuberako iyo pompe yawe ikora kuri 4000 psi cyangwa valve yawe ifunga gaze isharira, ntamwanya wo "gufunga bihagije."
