Gukora ifu yicyuma cyiza cyane nintambwe yambere yingenzi mubikorwa byose byifu ya metallurgie-kandi ihuriro ridakomeye mumurongo rishobora guhungabanya inzira zose zo hasi. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twatunganije ibiro birenga 12.000 bya cobalt-nikel hamwe nifu ya feri itagira umuyonga kumibiri ya hydraulic, amazu ya pompe, hamwe na AMS 5387 yujuje ubuziranenge kuva 2021. Ibyo twize ntabwo byari bihuye no gukwirakwiza ibice bya T800; Ubushuhe buri hejuru ya 0.08% bwateje hejuru yubutaka mugihe cyo gukanda isostatike; nabatanga isoko batabigenzuye batch traceability yatinze kugenzura abakiriya batatu. Umusaruro w'ifu-nyayo usaba ibirenze ibikoresho-bisaba disipuline ya metallurgjiya, protocole isubirwamo, no kwihanganira zeru kubitandukanye.
Atomisation: Aho Chimie Ihurira na Kinematics
Gazi ya atomisiyasi ikomeje kuba uburyo bwo gukoresha amavuta ashingiye kuri cobalt nka T800 na AMS 5387 - cyane cyane iyo umutekano muke uri munsi ya 200 MPa hydraulic imitwaro idashoboka. Dukoresha azote kumuvuduko wa 7.2 MPa hamwe na 45 ° gushonga-imigezi inging kugirango tugere kuri D.50 = 28-32 mm hamwe na <5% birenze (>106 μ m) ibice. Amazi atomisiyoneri akora kumashanyarazi yicyuma (urugero, SS316L kumfatiro za pompe), ariko nyuma yo gukomera nyuma ya atomisiyonike kuri 950 ° C muri hydrogen kugirango igabanye umwuka wa ogisijeni uri munsi ya 0.15%. Icy'ingenzi, ntituzigera dusiba ikizamini cyo gukwirakwiza ultrasonic mbere yo gushungura: niba ibice byongeye guterana mu masegonda 90 muri alcool ya isopropyl, twanze ubufindo - nubwo isesengura rya sikeri ryanyuze. Ibyo ni ukubera ko agglomerates ivunika bitateganijwe mugihe cyo guhuzagurika, ikora gradients ya density itangiza micro-crack mugihe cyo gucumura.
Rotary Electrode Inzira: Kuberako Mugihe udashobora kugura Oxide
Kuri cobalt-nikel nozzles ikora hejuru ya 650 ° C mubikoresho byo kumanura peteroli na gaze, kwinjiza okiside birateye ubwoba. Hano, itunganywa rya electrode itunganya (REP) itanga icyo atomisiyasi ya gaz idashobora: hafi-zero ogisijeni (<0.02 wt%), morphologie spherical, hamwe no kugenzura ingano nini (D.10–D90 span <1.8). Tuzunguruka AMS 5387 electrode kuri 12.500 rpm imbere mubyumba bya vacuum yabereye kuri 1 × 10−2 mbar. Ifu yavuyemo itemba kuri 22 s / 50g (Hall Flowmeter), igapakira kuri 62% yubucucike bugaragara, hamwe na sinters kuri> 99.2% yubucucike bwa HIP nta HIP. Ariko REP ntabwo ari rusange-turayirinda kumyuma isaba ibibanza bya nucleation. Ahubwo, dukoresha ifu-atomize ya Fe-2.5C ifu hamwe no gutandukanya karubone igenzurwa, hanyuma ukongeramo 0.8% flake grafite mugihe cyo kuvanga kugirango tumenye grafitike imwe nyuma ya sinter-anneal.
Amarembo meza: Nta poro yamababi atanyuze kuri Bane
Dushyira mubikorwa bine zidashobora kuganirwaho mbere yuko ifu yifu yimuka:
- Kugenzura imiti: ICP-OES kurwanya ibikoresho byemewe (CRM NIST SRM 1262a kuri Co, CRM NIST SRM 3125a kuri Ni); gutandukana> 0,15% bikurura retest yuzuye
- Ingano nini & imiterere: Gutandukanya Laser (Malvern Mastersizer 3000) + SEM amashusho; igipimo cya aspect> 1.8 cyangwa umuzenguruko <0.7 ntizemewe
- Urujya n'uruza: Hall Flowmeter + Ubunini bwa Scott; umuvuduko utemba ugomba kuba 18-24 s / 50g, ubwinshi bwa 2.8-3.1 g / cm³
- Kugaragaza umwanda: Ferrography yo kwambara imyanda ya ferrous; XRF gusikana kuri Cr, Mo, cyangwa Ti kuva kumurongo wabanjirije
Twandika ibisubizo byose muri sisitemu ya MES yemewe na ISO 9001-hamwe nibikoresho byuzuye bigaruka kumubare wubushyuhe mbisi. Niba itsinda ryananiwe n'irembo rimwe, rirasubirwamo-ntirimanurwa.
Kuki "Bikora" Bisobanura Kugenzura Itandukaniro, Ntabwo Umuvuduko
Inganda zimwe zirukana tonnage kumasaha. Twirukanye gutandukana bisanzwe. Mu musaruro w'ifu yacu mubikorwa by'ifu ya metallurgie, gukora bisobanura gufata D.50 gutandukana kuri ± 0.9 μ m mubice 10 bikurikiranye - ntibigabanya igihe cya atomisation 12%. Kubera iki? Kuberako inzu ya piston pompe yamashanyarazi ikozwe mubifu hamwe na ± 3.2 μ m D.50 itandukaniro ryerekanye 22% byikigereranyo cyo kumeneka mugupima igitutu kuri 350 bar. Dushora imari mugihe gikwiye cyo kugenzura ubushyuhe bwa plasma, kugenzura gazi ifunze-kugenzura, hamwe na kalibrasi ya sikeri ikora buri masaha 4. ROI ntabwo isohoka vuba-ikuraho rework ku $ 4.200 cobalt alloy valve imyanya.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ifata ifu ntabwo ari ibikoresho bibisi ahubwo nka ADN shingiro ya buri kintu. Umusaruro w'ifu mu ruganda rukora ifu ya metallurgie itangirana no kwemeza imiti ya chimie, ikomeza binyuze muri atome ya kinematike, kandi ikarangira nyuma y amarembo ane yigenga yemeza ko asubirwamo - atari rimwe gusa, ariko kuri kilo yose muri lot. Nuburyo igitutu cyumuvuduko kirokoka amasaha 15,000 yubuzima bwa pompe zo mumazi. Nuburyo winch center shaft rollers ikomeza kwiruka munsi ya 8 mm nyuma ya 500 yumuriro. Igihe kizaza ni icy'abakora ifu bapima intsinzi ntabwo ari kilo kuri buri mwanya - ahubwo ni microstructures kuri micrometero.
