Apo mainjiniya anotsanangura colloidal silica investment casting nokuda kwezvikamu zvepamusoro zvesimbi, havasi kungosarudza nzira-vari kusarudza vimbiso yekuita. Dimensional kugadzikana pasi pekupisa bhasikoro. Kupedzisa kwepamusoro kunobvisa post-cast kugaya. Microstructure kutonga mune cobalt alloys uko muganho wese wezviyo unokosha. Aya haasi mabhenefiti edzidziso. Ndidzo mhedzisiro dzatinoona zuva nezuva munzvimbo yedu inoenderana neISO muQingdao- uko batch yega yega yeAMS 5387 cobalt alloy pombi yedzimba kana T800 nozzle inopfuura nemutatu yakazvimirira CMM ongororo isati yasiya mutsetse.
Nei colloidal silica investment casting ichiendesa kune dzimwe nzira
Colloidal silica slurries inoumba yakasimba, yakanyanya kugadzika magomba eceramic kupfuura echinyakare ethyl silicate binders. Simba irori rinoshandura zvakananga kuita kushomeka kwemagoko panguva yekudonhedza uye kupfura-uye zero kushivirira kukanganisa mudzimba dzakatetepa-silinda dzakarongerwa 420 bar hydraulic service. Takayera kukura kwegoko pa 0.012% pa ° C kusvika 1100 ° C; vakwikwidzi vachishandisa mvura-girazi kana alumina-bonded masisitimu kazhinji inodarika 0.035%. Musiyano iwoyo? Ndiro mukaha uripo pakati pekurova ± 0.05 mm GD&T pane 320 mm piston pombi yekugara-uye kuibvisa mushure mekutanga-chinyorwa chekuongorora.
Isu hatimhanye colloidal silica casting semutsetse wakamira. Iyo yakabatanidzwa nechaiyo CNC machining mune imwe kuyerera kwekushanda: kanda iyo yakakosha geometry, muchina wakakosha chisimbiso nzvimbo uye tambo mafomu, wozoisa inodzorwa kupisa kurapwa * pasina kutyora traceability *. Hapana handoffs. Hapana chiziviso zvakare. Chese chikamu chinotakura laser-etched lot ID inobatanidza kumashure kune yakaomeswa zvinhu certs, shell dip matanda, machati echoto, uye yekupedzisira CMM mishumo.
Uku kubatanidzwa kunogadzirisa marwadzo chaiwo: warpage mu-high-alloy steel castings. Mutengi akambotiunzira simbi isina tsvina yevharuvhu iyo yakamonyoroka 0.18 mm mushure mekunetseka-kubvisa-nekuti mutengi wavo akakanda, akatumirwa, uye rega mutengi atore kurapwa kwekupisa zvakasiyana. Isu tinodzokorora tichishandisa yakafanana T800-giredhi feedstock, asi takabata chikamu muchoto chedu chevacuum nekukurumidza mushure mekuzunza. Kukanganisa kwekupedzisira: 0.023 mm. Kwete mashiripiti. Ingodzora nhoroondo yekupisa-uye yakazara maitiro aridzi.
Chii chinoita kuti yechokwadi colloidal silica investimendi yekukandira fekitori yakasiyana
Zvitoro zvakawanda vanozvidaidza kuti "mafekitori ekudyara mari." Vashoma ndivo varidzi veiyo colloidal silica slurry formulation, shell drying protocols, uye dewaxing ramp profiles inotsanangura budiriro nema superalloys. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Isu tinogadzirisa viscosity vhiki nevhiki tichishandisa Brookfield viscometers, kuongorora pH kukukurwa munguva chaiyo, uye tinoramba chero slurry batch kunze kwe9.2-9.6 pH-kunyangwe ichitaridzika zvakanaka. Sei? Nekuti pH inochinja inoshandura silica particle zeta inogona, iyo inoshandura ganda density, permeability, uye pakupedzisira, kushata kwepamusoro (Ra) pazvikamu zvakapedzwa. Takaona Ra achisvetuka kubva 1.8 µm kusvika 4.3 µm apo pH yakakukurwa kuenda ku9.8.
Tinobatawo kupfurwa kwemagoko sesimbi—kwete simbi chete. Yedu kilns ramp pa ≤60 ° C / awa kusvika ku1050 ° C, chengetedza kwemaminitsi makumi mapfumbamwe, wozotonhorera pa ≤40 ° C / awa. Iyo inononoka kutenderera inodzivirira microcracking muzvikamu zvakakora zvecobalt-nickel castings. Imwe pombi yeEuropean OEM yakachinjira kwatiri mushure mekunge vatengesi vaviri vekutanga vaunza yakatsemuka AMS 5387 impeller hubs. Dzidzi yechikonzero chekuongorora kwavo kwakaratidza kupisa kwekutya kutsemuka kunobva paganda-kusvika-simbi interfaces. Kupfurwa kwedu kwakavabvisa. Kwete nekushandura alloy-asi nekuremekedza kuti goko rinofema sei.
- Certified raw materials chete - coil yese inoteedzerwa kune mill test mishumo
- Hapana subcontracted shell making kana dewaxing-100% in-house process control
- GD&T-yekutanga dhizaini ongororo: isu tinomira dhizaini angles pazasi 0.5 ° kusati kwatanga kushandisa
- Surface kupera kusimbiswa pane optical profilometers-kwete kungoona cheki
Chaiyo-yepasirese application uko colloidal silica casting inoratidza kuti haigone kutaurirana
Mavharuvhu ekudzvanya kwemafuta ekumahombekombe egungwa & gasi manifolds anoda kushanda-pasina kubuda pa -46°C kusvika +121°C. Kukandira jecha hakugone kubata 0.02 mm chigaro che concentricity inodiwa. Yakajairwa investimendi yekukandira inonetsekana nehuwandu hwekupisa kweASTM A494 M35-1 dzimba. Colloidal silica inoita zvese zviri zviviri: kushivirira kwakasimba * uye * kutsemuka-isina kuvimbika kune yakanyanyisa kupisa gradient.
Isu nguva pfupi yadarika takagadzira pakati shaft rollers yeinjiniya mota winch masisitimu - zvikamu zvine 220 mm OD, 45 mm madziro emadziro, uye yemukati spline geometry. Mutengi aida kuomarara ≥58 HRC *kuburikidza nechikamu*, kwete kungoomeswa. Colloidal silica yakagonesa yunifomu yegomba ukobvu, kuenderana kusimba mareti, uye zero porosity munzvimbo yakakosha inotakura-inotakura. Machining nguva yakadonha 37% kupesana nejecha-cast blanks nekuti isu takaendesa padhuze-neti chimiro nekufungidzirwa kugoverwa kwemasheya.
Zvimwe zviitiko zvekushandisa zvakasimbiswa zvinosanganisira:
- Cobalt alloy nozzles for high-velocity abrasive slurry pumps (T800 giredhi, 62–65 HRC)
- Pombi nheyo inoda flatness ≤0.08 mm pamusoro pe850 mm kureba
- Non-standard piston rod vatakuri vane yakabatanidzwa kutonhora nzira-yakakandwa, kwete welded
Kusarudza yako colloidal silica investimendi yekukandira fekitori haisi yehuwandu - ndeye kugona
Kana chikamu chako chichida AMS 5387, T800, kana UNS R30005-uye uchifanira kurarama 10,000+ kumanikidzwa kutenderera pasina microcrack initiation-unoda zvinopfuura foundry. Unoda mumwe wako anobata colloidal silica kwete sebhainda, asi sesimbi inoshanduka. Ndiani anosimbisa simba regoko neASTM C133 compression bvunzo-kwete kungoona kuongorora. Ndiani anobatanidza kukanganisa kwega kwega kwekukanda kune yakatarwa parameter shanduko: slurry age, dewaxing rate, kana kunyange ambient humidity panguva yekunyura.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda nenzira iyoyo-kwete nekuti zviri nyore, asi nekuti mishoni-yakakosha zvikamu zvinosiya nzvimbo yekufungidzira. Isu tinoshambadza yedu colloidal silica process windows. Isu tinogovana dhata density data nevatengi. Isu tinorega mainjiniya aongorore yedu CMM calibration matanda. Kujeka ikoko hakusi kushambadzira. Ndiwo maonerwo aunoita kuti "colloidal silica investment casting fekitori" pabepa inoenderana nezvinofamba pasi pechitoro.
Kune chaiyo simbi zvikamu uko kukundikana hakusi sarudzo, iyo fekitori yakakodzera haingokanda simbi. Inoisa chivimbo.
