Paunenge uchikanda cobalt alloy pombi yekugara ye-high-pressure hydraulic service-kana AMS 5387 nozzle iyo inofanirwa kurarama 650 ° C uye cyclic thermal stress-iyo ceramic core haingori chinhu chinoraswa mold. Ndiyo mugadziri akanyarara wemukati geometry, mutsigiri wemadziro ukobvu kudzora, mutsara wekutanga wedziviriro kurwisa dimensional kudonha mukukanda mari. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Takaona maceramic cores achitadza pakati pekudururwa paT800-based impeller shrouds-kwete nekuda kwekuneta kwebhainda, asi nekuti iyo coefficient yekuwedzera kwekushisa (CTE) kusapindirana negoko haina kusimbiswa pazere 25°C ramp0-1111. Ndosaka "ceramic musimboti wekudyara fekitori yekukanda" haisi chinhu chekutsvaga chekutsvaga kwatiri. Iyo chaiyo yakatarwa nemhedzisiro yenyika chaiyo.
Isu tinogadzira anopfuura zviuru gumi nezviviri zveceramic cores pagore - imwe neimwe yakagadzirirwa imwe alloy system, gating dhizaini, uye post-cast machining envelopu. Yedu yakajairwa cores inoshandisa fused silica-alumina blends neCTEs yakarongedzwa kusvika ± 0.2 × 10⁻⁶/°C kupesana neCoCr alloys; maumbirwo echivanhu anosanganisira zirconia-reinforced variants for>1200°C titanium aluminide miedzo. Kusiyana ne-off-the-sherufu cores inotengeswa nevegeneral refractory suppliers, yedu inoitwa matatu isingagone kutaurirana isati yaburitswa: XRD chikamu kugadzikana pa1000 ° C, kutonhora kupwanya simba ≥18 MPa mushure mekudonha, uye dimensional kudzokororwa kunosimbiswa kuburikidza neCT scanning-kwete chete macalipers. Isu takayera musimboti-kune-musimboti kusiyanisa pasi pe0.015 mm pa80 mm-kureba kwemukati ndima, yakakosha kana yekupedzisira machining mvumo ingori 0.15 mm padivi.
Vamwe vanogona kukakavara kuti jecha-kukanda kana kuti machined-in-place cores inoderedza nguva yekutungamirira. Asi mune yedu ruzivo nepiston pombi silinda dzimba, idzo dzimwe nzira dzinodhura zvakanyanya kudzika. Majecha ejecha anosiya kushata pamusoro peRa 12.5 µm-hazvigamuchirwe kune hydraulic sealing nzvimbo inoda Ra ≤1.6 µm mushure mekupedza machining. Machina macores anounza ma microcracks kubva kumudziyo wekushandisa, ayo anopararira panguva yekupfurwa kwegoko uye kukonzera kusimudzwa kwegomba. Isu takatsvaga 23% yepamusoro zvimedu zvimedu pazvikamu zvakadaro kupesana neceramic cores ine yakagadziridzwa girinhi simba uye inodzorwa sintering profiles. Mhinduro haina kukurumidza - ine hungwaru: pre-yakasimbiswa musimboti geometry, inofananidzwa nemafuta ekupisa, uye anoteedzera batch marekodhi akasungirirwa kune yega yega yekukanda.
Chii chinoparadzanisa akavimbika ceramic musimboti mutengesi kubva kune mutengesi wekutengesa? Zvinhu zvina zvatinoongorora zuva nezuva:
- Raw material certification: Yese silica batch inotakura ASTM C704 bvunzo mishumo-kwete chete zviziviso zvemupi.
- Process mapping: Core kuomeswa kunotevera ISO 9001-inodzorwa humidity ramps (kwete yakatarwa-nguva masheti), kudzivirira micro-kutsemuka mu 3.2 mm-makobvu vanes
- Dimensional kuzvidavirira: Isu tinoyera ese musimboti neZeiss CONTURA G2 RDS CMM, kwete yekuona inofananidzira-yakakosha kune GD&T-inodzorwa maficha senge chinzvimbo kushivirira Ø0.05 mm
- Alloy-specific validation: Co-based cores inoedzwa mune chaiyo investment shell masisitimu uchishandisa yako chaiyo slurry viscosity uye dip cycle, kwete generic plaster molds.
Iyi nhanho yekudzora inotitendera kuti tiunze ceramic cores inobata chokwadi kuburikidza nekudonhedza, kupfura, uye kudira simbi-kunyangwe kune akaomarara majometri semiviri-yevharuvhu miviri ine intersecting 2.5 mm-dhiyamita yekutonhodza nzira. Vatengi muNorth America neEurope vanogara vachishuma 15-20% mashoma ekugadzirisa zviitiko pamitambo inoda kushivirira kwemukati (± 0.08 mm). Hapana mashiripiti. Ingo nyorwa maparamendi ehurongwa, yakagadziriswa metrology, uye metallurgical alignment yakavakirwa mukati mepakati-isina kuwedzerwa sekufunga kwekupedzisira.
Kana iwe uchitsvaga a ceramic musimboti wekudyara kukanda fekitori Chishandiso uko mashandiro anoshanda anoenderana nemukati contour kutendeka-kwete chete "inokwana"-ipapo mapepa edatha data uye nguva yekuendesa zvine basa shoma pane kupisa kuenderana matanda uye CMM yekuongorora mishumo. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Tinobata core yega yega sechinhu chinoshanda, kwete chinodyiwa. Isu tinogovana yakazara bvunzo data nevatengi pamberi pekutanga chinyorwa kubvumidzwa. Isu tinogadzirisa mabinder ratios zvichienderana nekukwanisa kwegoko rako - kwete yedu yakasarudzika formula. Uye isu tinochengeta batch marekodhi kwemakore gumi, kwete kungotevedzera, asi kuti iwe ugone kuteedzera chero kusarudzika kumashure kune chaiyo kiln run, raw lot, uye opareta shift.
Ramangwana rekukanda chaiko harisi remavira mahombe kana kukurumidza maCNC. Izvo ndezvekubvisa kusiyanisa pamavambo-kutanga nepakati. Sezvo kudiwa kuri kukura kune matete madziro, migero yakaoma, uye yakakwirira-tembiricha alloys seT800 neCMSX-4, ceramic cores inosimuka kubva mukugonesa tekinoroji kuenda kugedhi remhando yepamusoro. Iko kushanduka kunotanga nekubvunza kwete "Ingaitwe here?" asi "Mafambiro ayo anogona kufanotaurwa nenzira kwayo-uye kuratidzwa?" Isu takavaka nzvimbo yedu, maprotocol edu, uye kudyidzana kwedu kutenderedza mubvunzo iwoyo. Nekuti kana chikamu chako chichishanda pabhawa mazana matatu nemakumi mashanu mukati memusangano wepombi yekumahombekombe, hapana nzvimbo yekufungidzira munzvimbo isina hoko.
