Xa iinjineli zichaza colloidal silica investment casting kwiindawo zetsimbi eziphezulu, abakhethi nje inkqubo-bakhetha isiqinisekiso sokusebenza. Uzinzo lweDimensional phantsi kwebhayisekile eshushu. Ukugqitywa komphezulu okuphelisa ukucola okusemva. Ulawulo lweMicrostructure kwi-cobalt alloys apho yonke imida yeenkozo ibalulekile. Ezi ayizizo iinzuzo zethiyori. Ziziziphumo esizibona imihla ngemihla kwiziko lethu elithobela i-ISO eQingdao-apho yonke ibhetshi ye-AMS 5387 cobalt alloy pump yezindlu okanye i-T800 nozzle idlula uhlolo oluzimeleyo lweCMM ngaphambi kokushiya umgca.
Kutheni i-colloidal silica investment casting ihambisa apho ezinye iindlela zizinzile
I-Colloidal silica slurries yenza amaqokobhe e-ceramic omelele ngakumbi, azinzileyo ngokushushu ngakumbi kunezibophelelo ze-ethyl silicate zesintu. Loo mandla aguqulela ngokuthe ngqo kwiintanda ezimbalwa zeqokobhe ngexesha le-waxing kunye nokudubula-kwaye zero ukunyamezela ukugqwetheka kwizindlu ze-cylinder ezinqabileyo ezilinganiselwe kwi-420 bar yenkonzo ye-hydraulic. Silinganise ukwanda kweqokobhe nge-0.012% nge °C ukuya kutsho kwi-1100°C; abakhuphisanayo abasebenzisa i-water-glass okanye i-alumina-bond systems badla ngokudlula i-0.035%. Loo mahluko? Ingumsantsa phakathi kokubetha i-± 0.05 mm GD & T kwi-320 mm yezindlu zepiston yepiston-kwaye uyichithe emva kokuhlolwa kwenqaku lokuqala.
Asiyibalekisi i-colloidal silica casting njengomgca ozimeleyo. Idityaniswe nobuchwephesha be-CNC obuchanekileyo kwindlela yokusebenza enye: phosa ijiyometri engundoqo, umatshini wokutywina obalulekileyo kunye neefom zentambo, emva koko usebenzise unyango lobushushu obulawulwayo *ngaphandle kokulandela umkhondo *. Akukho handoffs. Akukho kuchongwa kwakhona kwezinto. Inxalenye nganye iphethe i-ID ye-laser-etched lot edibanisa umva kwiicerts zemathiriyeli ekrwada, ii-shell dip logs, iitshathi zesithando somlilo, kunye neengxelo zokugqibela zeCMM.
Oku kudityaniswa kusombulula ingxaki yangempela yentlungu: i-warpage kwi-high-alloy steel castings. Umthengi wake wasizisela i-valve yensimbi engenasici ejikeleza i-0.18 mm emva kokunciphisa uxinzelelo-kuba umthengisi wabo uphonswe, uthunyelwe, kwaye uvumele umthengi ukuba aphathe unyango lobushushu ngokwahlukileyo. Siphinda sisebenzisa i-T800-grade feedstock, kodwa sibambe indawo kwiziko lethu lokucoca ngokukhawuleza emva kokushukunyiswa. Ukugqwethwa kokugqibela: 0.023 mm. Hayi umlingo. Imbali elawulwayo ye-thermal-kunye nobunini benkqubo epheleleyo.
Yintoni eyenza imveliso yotyalo-mali ye-colloidal yokwenyani yahluke
Iivenkile ezininzi zizibiza ngokuba "ziifektri zotyalo-mali." Bambalwa abangabanini be-colloidal silica slurry formulation, iiprotocol zokomisa iqokobhe, kunye neeprofayile zeendlela ezikhupha i-waxing ezichaza impumelelo nge-superalloys. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Silinganisa i-viscosity ngeveki sisebenzisa i-Brookfield viscometers, sibeke iliso kwi-pH drift ngexesha lokwenyani, kwaye sikhabe nayiphi na ibhetshi eludaka ngaphandle kwe-9.2–9.6 pH-nokuba ikhangeleka igqibelele. Ngoba? Ngenxa yokuba i-pH itshintsha i-silica particle i-zeta enokubakho, etshintsha ukuxinana kweqokobhe, ukufikeleleka, kwaye ekugqibeleni, uburhabaxa bomphezulu (Ra) kwiindawo ezigqityiweyo. Siye sabona uRa etsiba ukusuka kwi-1.8 µm ukuya kwi-4.3 µm xa i-pH ikhukuliseka ukuya kwi-9.8.
Kwakhona ukudutyulwa koonokrwece sikuphatha njengesinyithi—kungekhona nje izinto ezenziwe ngodongwe. I-kilns yethu i-ramp kwi-≤60 ° C / iyure ukuya kwi-1050 ° C, ibambe imizuzu ye-90, emva koko ipholile kwi-≤40 ° C / iyure. Lo mjikelo ucothayo unqanda ukukrala kancinci kumacandelo ashinyeneyo e-cobalt-nickel castings. Ipompo enye yaseYurophu iOEM yatshintshela kuthi emva kokuba ababoneleli ababini bangaphambili bezise i-AMS 5387 impeller hubs. Uhlalutyo lwesizathu esisisiseko sawo lubonise ukothuka kobushushu obuvela kwigobolondo ukuya kujongano lwentsimbi. Iprofayile yethu yokudubula yaziphelisa. Akunjalo ngokutshintsha ingxubevange—kodwa ngokuhlonela indlela iqokobhe eliphefumla ngayo.
- Imathiriyeli ekrwada eqinisekisiweyo kuphela-yonke ikhoyili elandelekayo kwiingxelo zovavanyo lokusila
- Akukho ukwenza iqokobhe elingaphantsi kwekontraka okanye ukuthotywa kwewaxisi-100% yolawulo lwenkqubo yangaphakathi
- Uphononongo loyilo lokuqala lwe-GD&T: sifaka iflegi yedrafti yee-engile ngaphantsi kwe-0.5 ° phambi kokuba isixhobo siqale
- Ukuqinisekiswa kokugqitywa komphezulu kwiiprofilometers zamehlo-hayi nje ukujonga okubonakalayo
Usetyenziso lwehlabathi lokwenyani apho i-colloidal silica casting ingqina ukuba ayinakuthethwa
Iivalvu zoxinzelelo lweoyile ekude nonxweme kunye nobuninzi berhasi zifuna ukusebenza okungavuziyo ku -46°C ukuya +121°C. Ukugalelwa kwesanti akukwazi ukubamba i-0.02 mm yokugxila kwesitulo esifunekayo. Umzabalazo wotyalo-mali osemgangathweni kunye nobunzima bobushushu bezindlu ze-ASTM A494 M35-1. I-silica ye-Colloidal yenza zombini: ukunyamezela okuqinileyo *kunye* nengqibelelo engenantandabuzo kuzo zonke izithambiso ezishushu ezigqithisileyo.
Kutshanje sivelise iirola eziziko leshaft yeenkqubo zobunjineli bewinch yemoto-amacandelo ane-220 mm OD, 45 mm ubukhulu bodonga, kunye nejometri ye-spline yangaphakathi. Umthengi wayefuna ubulukhuni ≥58 HRC *ngecandelo*, hayi nje ukuqina. I-silica ye-Colloidal yenza ukuba ubukhulu beqokobhe obufanayo bufane, amazinga okuqina angaguqukiyo, kunye ne-zero porosity kwindawo ebalulekileyo ethwele umthwalo. Ixesha lomatshini lehle nge-37% xa kuthelekiswa nezithuba zesanti kuba sihambise imilo ekufutshane nenetha enokuxelwa kwangaphambili.
Ezinye iimeko zokusetyenziswa eziqinisekisiweyo ziquka:
- Imilomo yengxubevange yeCobalt yeempompo zodaka oluludaka lwesantya esiphezulu (i-T800 grade, 62–65 HRC)
- Iziseko zempompo ezifuna ukucaba ≤0.08 mm ngaphezu kobude be-850 mm
- Abathwali beentonga zepiston ezingekho mgangathweni ezinamashaneli okupholisa adibeneyo-aphoswe, angenawo i-welded
Ukukhetha i-colloidal silica investment casting factory yakho ayithethi ngomthamo-imalunga nobuchule
Ukuba inxalenye yakho ifuna i-AMS 5387, T800, okanye i-UNS R30005-kwaye kufuneka uphile 10,000+ imijikelezo yoxinzelelo ngaphandle kokuqaliswa kwe-microcrack-udinga ngaphezu kwe-Foundry. Ufuna iqabane eliphatha i-silica ye-colloidal kungekhona njengesibophelelo, kodwa njenge-metallurgical variable. Ngubani oqinisekisa amandla egobolondo nge-ASTM C133 yovavanyo loxinzelelo-kungekhona nje ukujonga okubonakalayo. Ngubani odibanisa zonke iziphene zokuphosa kutshintsho lweparameter ethile: iminyaka eludaka, isantya sokuthotywa, okanye nokufuma okujikeleze ngexesha lokudipha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngaloo ndlela-hayi ngenxa yokuba ilungile, kodwa ngenxa yokuba izinto ezibalulekileyo zobuthunywa zishiya indawo yokucinga. Sipapasha iifestile zethu ze-colloidal silica process. Sabelana ngedatha yoxinaniso lweqokobhe kunye nabathengi. Sivumela iinjineli ukuba ziphicothe iilog zethu zokulinganisa iCMM. Oko kungafihlwayo akuthengisi. Yindlela oqinisekisa ngayo ukuba "i-colloidal silica investment casting factory" ephepheni ihambelana nento esebenza kumgangatho wevenkile.
Kwiindawo ezichanekileyo zetsimbi apho ukungaphumeleli akusiyo inketho, i-factory efanelekileyo ayigcini nje ukuphosa isinyithi. Ikhupha ukuzithemba.
