Iyo ba injeniyeri bagaragaje colloidal silica ishoramari kubice byubunyangamugayo buhanitse, ntabwo bahisemo inzira-bahitamo garanti yimikorere. Ihagarikwa ryimiterere munsi yumukino wo gusiganwa ku magare. Kurangiza isura ikuraho gusya nyuma. Igenzura rya microstructure muri cobalt alloys aho imbibi zose zingana. Ibi ntabwo aribyiza byo kwigisha. Nibisubizo tubona burimunsi mubigo byacu byubahiriza ISO muri Qingdao-aho buri cyiciro cya AMS 5387 cobalt alloy pompe amazu cyangwa T800 nozzle inyura mubugenzuzi butatu bwa CMM mbere yo kuva kumurongo.
Kuberiki colloidal silica ishoramari itanga aho ubundi buryo buhagaze
Silloidal silica slurries ikora imbaraga, nyinshi zumubumbe wa ceramic zihamye kuruta gakondo ya Ethyl silicate binders. Izo mbaraga zihindurwamo ibice bike byigikonoshwa mugihe cyo guta no kurasa - no kutihanganira na gato kugoreka amazu ya silindari yometseho uruzitiro ruteganijwe kuri 420 ya hydraulic. Twapimye kwaguka kw'igikonoshwa kuri 0.012% kuri ° C kugeza kuri 1100 ° C; abanywanyi bakoresha amazi-ibirahuri cyangwa sisitemu ya alumina ikunze kurenga 0.035%. Itandukaniro? Ni ikinyuranyo cyo gukubita ± 0,05 mm GD&T ku nzu ya pompe ya piston ya mm 320 - no kuyisiba nyuma yo kugenzura ingingo ya mbere.
Ntabwo dukoresha siloidal silika casting nkumurongo wihariye. Yinjijwe hamwe na CNC itunganijwe neza mumurimo umwe wakazi: shyira geometrie yibanze, imashini ikomeye yo gufunga imashini hamwe nudushusho, hanyuma ushyireho uburyo bwo kuvura ubushyuhe bugenzurwa * utabanje guca ukubiri *. Nta ntoki. Nta bikoresho byongeye kumenyekana. Igice cyose gitwara indangamuntu ya laser ihuza gusubira mubikoresho fatizo, ibishishwa by'ibishishwa, ibicanwa by'itanura, na raporo ya nyuma ya CMM.
Uku kwishyira hamwe gukemura ikibazo cyububabare nyabwo: warpage mumashanyarazi menshi. Umukiriya yigeze kutuzanira umubiri wibyuma bitagira umuyonga wapimye mm 0,18 nyuma yo kugabanya ibibazo - kuberako uwabitanze yateje, yohereza, kandi areka umukiriya akora imiti itandukanye. Twongeye gusubiramo dukoresheje ibiryo byo mu rwego rwa T800, ariko twagize uruhare mu itanura ryacu rya vacuum ako kanya nyuma yo kunyeganyega. Kugoreka kwanyuma: 0,023 mm. Ntabwo ari amarozi. Kugenzura gusa amateka yubushyuhe-hamwe nuburyo bwuzuye nyirubwite.
Niki gituma uruganda rwukuri rwa silika rwishoramari rutera uruganda rutandukanye
Amaduka menshi yiyita “inganda zishoramari.” Bake mubyukuri bafite siloidal silica slurry formulaire, protocole yumisha shell, hamwe na dewaxing imyirondoro isobanura intsinzi hamwe na superalloys. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Turasuzuma buri cyumweru dukoresheje viscometer ya Brookfield, tugakurikirana umuvuduko wa pH mugihe nyacyo, kandi tukanga icyiciro icyo ari cyo cyose cyihuta hanze ya 9.2-9.6 pH - nubwo cyaba cyiza. Kubera iki? Kuberako pH ihindura silika agace ka zeta ubushobozi, buhindura ubwinshi bwikigero, ubworoherane, kandi amaherezo, uburinganire bwubutaka (Ra) kubice byarangiye. Twabonye Ra gusimbuka kuva 1.8 µm kugeza kuri 4.3 µm mugihe pH yatembye ikagera kuri 9.8.
Dufata kandi kurasa ibisasu nka metallurgie - ntabwo ari ububumbyi gusa. Amatanura yacu arazamuka kuri ≤60 ° C / isaha kugeza kuri 1050 ° C, fata iminota 90, hanyuma ukonje kuri ≤40 ° C / isaha. Uku kuzenguruka gahoro kurinda microcracking mubice byimbitse bya cobalt-nikel. Pompe imwe yu Burayi OEM yaraduhinduye nyuma yuko abatanga ibicuruzwa bibiri babanje gutanga AMS 5387 yamenetse. Isesengura ryintandaro yabyo yerekanaga ibice byamashyanyarazi bituruka kumasaka-yicyuma. Umwirondoro wo kurasa wabikuyeho. Ntabwo ari uguhindura amavuta - ahubwo nukubaha uburyo igikonoshwa gihumeka.
- Ibikoresho fatizo byemewe gusa - buri coil ikurikiranwa na raporo yikizamini
- Ntabwo igishishwa gikora cyangwa gukora dewaxing - 100% mugikorwa cyo kugenzura murugo
- GD & T-ibishushanyo mbonera byambere: dushyira ibendera kumurongo munsi ya 0.5 ° mbere yuko ibikoresho bitangira
- Ubuso burangiza kwemeza kuri optique ya profilometero - ntabwo ari kugenzura gusa
Porogaramu nyayo yisi aho colloidal silica casting yerekana ko bidashoboka
Umuvuduko ukabije wamavuta ya gazi yo hanze no gazi arasaba gukora ubusa -46 ° C kugeza + 121 ° C. Gutera umucanga ntibishobora gufata intebe ya mm 0,02 isabwa. Igishoro gisanzwe cyo gushora urugamba hamwe nubushyuhe bwamazu ya ASTM A494 M35-1. Siloidal silika ikora byombi: kwihanganira gukomeye * na * kutagira ubunyangamugayo hejuru yubushyuhe bukabije.
Duheruka gukora imashini ya shitingi ya sisitemu yo gutwara ibinyabiziga - ibice bifite mm 220 OD, uburebure bwa mm 45, hamwe na geometrie y'imbere. Umukiriya yari akeneye gukomera ≥58 HRC * binyuze mu gice *, ntabwo ari ikibazo gusa. Siloidal silika yatumaga igishishwa kimwe, igipimo gihamye, hamwe na zeru zeru muri zone itwara imitwaro ikomeye. Igihe cyo gukora cyagabanutseho 37% ugereranije numusenyi watewe kuko twatanze hafi-net ishusho hamwe nogusaranganya ibicuruzwa.
Izindi manza zagaragaye zikoreshwa zirimo:
- Cobalt alloy nozzles ya pompe yihuta cyane (pompe ya T800, 62-65 HRC)
- Urufatiro rwa pompe rusaba ubunini ≤0.08 mm hejuru ya 850 mm z'uburebure
- Abatwara piston idasanzwe isanzwe ifite imiyoboro ikonje-ikozwe, ntabwo isudwa
Guhitamo uruganda rwa siloidal silika ishoramari ntirureba ubushobozi-bijyanye n'ubushobozi
Niba igice cyawe gisaba AMS 5387, T800, cyangwa UNS R30005 - kandi kigomba kurokoka 10,000+ cyumuvuduko utabanje gutangiza microcrack - ukeneye ibirenze gushinga. Ukeneye umufatanyabikorwa ufata silika ya colloidal ntabwo ari binder, ahubwo nkimpinduka ya metallurgical. Ninde wemeza igishishwa imbaraga hamwe na ASTM C133 ibizamini byo kwikuramo - ntabwo ari ubugenzuzi gusa. Ninde uhuza inenge zose ziterwa no guhinduranya ibintu: imyaka itinda, igipimo cyo kugabanuka, cyangwa nubushuhe bwibidukikije mugihe cyo kwibiza.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora muri ubwo buryo - ntabwo ari ukubera ko byoroshye, ariko kubera ko ibice byingenzi byubutumwa bidasiga umwanya wo gutekereza. Dutangaza ibyerekezo bya silika ya silika. Twasangiye amakuru yubucucike bwabakiriya. Twemerera injeniyeri kugenzura ibiti bya Calibibasi ya CMM. Ukwo gukorera mu mucyo ntabwo ari kwamamaza. Nuburyo ugenzura ko "colloidal silica Investment casting uruganda" kumpapuro zihuye nibiri kumaduka.
Kubice byicyuma neza aho kunanirwa atari amahitamo, uruganda rukwiye ntirutera ibyuma gusa. Bitera icyizere.
