Kana mainjiniya achitsanangura silica sol investimendi yekukandira chaiyo simbi zvikamu, ivo havasi kungosarudza maitiro-vari kusarudza vimbiso yekudzikama kwedimensional, kutendeka kwepamusoro, uye kuenderana kwesimbi pasi pemamiriro ebasa rakanyanyisa. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takakanda nhamba dzinopfuura 12,000 dzezvikamu zvakasiyana tichishandisa silica sol-yakawanda mucobalt-nickel alloys seAMS 5387 neT800-apo ± 0.05 mm kushivirira hakusi chinangwa; ndiyo yekutanga.
Nei silica sol-kwete girazi remvura kana plaster-inoburitsa zvinodzokororwa nemazvo
Vatengi vazhinji vanofunga kuti "kudyara kwekudyara" inzira imwe chete. Hazvisizvo. Iyo binder system inotsanangura miganhu yekuita. Silica sol inoshandisa colloidal silica (SiO₂ nanoparticles yakamiswa mumvura) seyekutanga binder. Yayo yakaderera viscosity inopinda mune yakanaka ruzivo; refractoriness yayo yakakwirira inomira 1,550°C kudurura tembiricha nokuda superalloys. Magirazi emvura masisitimu anotsemuka pasi pekupisa kwekupisa. Plaster molds inosvibisa pamusoro pe600 ° C-inoparadza microstructure mucobalt-based pump housings.
Isu takaona vatengi vachichinja kubva kugirazi remvura kuenda kusilica sol mushure mekunge matatu akateedzana mabheji atadza kumanikidza kuyedzwa pa420 bar. Root cause? Microcracks mumadziro egoko, isingaonekwe nemaziso asi yakasimbiswa neSEM fractography. Silica sol shells haaratidze zvikanganiso zvakadaro-kunyangwe pa 0.3 mm-makobvu vanes mune turbine nozzle maassemblies. Ndosaka yedu silica sol investimendi yekukandira fekitori inobata ISO 9001: 2015 certification ine yakazara traceability pasi kusvika pakupisa yakawanda, particle size distribution of the slurry, uye dova rekudzora panguva yekuomesa.
Vertical kubatanidzwa hakusi kushambadzira-ndiwo mabatiro atinoita ± 0.03 mm pa 300-mm silinda dzimba
Vamwe vatengesi vanobudisa magomba, kukanda, uye kugadzira. Isu tinoita ese ari matatu mune imwe ISO-inoenderana nzvimbo muQingdao. Nei izvozvo zvine basa? Nekuti piston pombi silinda imba inoda kuenzanisa kuwedzera kwemafuta pakati pegoko, alloy, uye CNC fixture. Kana kukanda uye kugadzira kunoitika pasi pedenga remba, isu tinoyera CMM probes inopesana ne-as-cast datum nzvimbo-kwete dzidziso dzeCAD modhi. Isu tinoyera shrinkage vectors pane alloy batch, tozogadzirisa nzira dzematurusi tisati tacheka.
Semuyenzaniso: AMS 5387 cobalt alloy inodzika 1.82% zvakatevedzana mu silica sol molds — asi chete kana dova richigara pasi -25°C panguva yekuomesa kwekupedzisira. Isu tinonyora nguva yega yega yekuomesa. Kana humidity spikes, isu tinodzokorora goko. Hapana kunze. Chirango ichocho chinotibvumira kubata GD&T callouts sechinzvimbo ⊕ 0.05 mm MMC pamakomba masere akaenzana akaenzana ekukwira-pasina kugaya kwechipiri.
Kusimbiswa kwepasirese-kwete ma-lab specs-inofambisa zvinhu uye sarudzo yemaitiro
Vatengi vanobvunza kuti: "Ungakanda T800 alloy mune isiri-standard winch centre shaft roller?" Hongu-asi chete kana tikasimbisa dhizaini yegedhi kutanga. T800 inoomesa neyakaomarara dendritic segregation. Gedhi risina kuiswa zvakanaka rinokonzera centreline porosity pa 75-mm dhayamita pamapfudzi. Isu tinomhanyisa simulation yekusimbisa (tichishandisa MAGMASOFT®), tobva tasimbisa neX-ray CT scans pamatatu ekuyedzwa. Ipapo ndipo patinobvumira muenzaniso.
Apa ndipo apo ruzivo rwunoparadzanisa dzidziso kubva pakupihwa. Takakanda cobalt alloy nozzles yemapombi ejekiseni repasi pegungwa anoshanda pa120°C uye 350 bar. Kukundikana kunoreva $2M kunonoka. Saka isu tinoyedza batch yega yega: tensile simba ≥1,050 MPa, elongation ≥8%, uye intergranular corrosion resistance paASTM G28A. Hapana chitupa pasina bvunzo data. Hapana kutumirwa pasina kusaina gwaro rekuongorora.
Chii chekutarisira kana uchibatana ne silica sol investment casting fekitori
Kana chikamu chako chine madziro matete (<2 mm), ndima dzemukati dzakaoma, kana zvinoda Rz ≤ 1.6 µm se-cast-cast surface finish-unoda silica sol. Asi kubudirira kunoenderana nekubatana, kwete kugona chete. PaQINGDAO QIANGSENYUAN, ongororo yeinjiniya inotanga tisati tataura mashoko: tinoisa mureza pasi pe 0.5°, tinokurudzira radii yekuzorodza pfungwa, uye tinosimbisa kuti chinhu chinogona kukandwa here—kana kuti chinofanira kugadzirwa mushure mekudirwa.
Hatitengesi macastings. Isu tinoburitsa zvinhu zvinoshanda: mavharuvhu anonamira pa450 bar, pombi nheyo dzinonyorovesa 3,200 rpm vibration, winch shaft rollers inopona 10⁶ cycles mumhepo ine munyu. Kurongeka kwese kunosanganisira zvinhu certs, CMM mishumo, uye kupisa matanda ekurapa. Kutungamira nguva? Masvondo gumi nemana echinyorwa chekutanga, mavhiki masere ekudzokorora-akavimbiswa. Kwete kuvimbiswa. Guaranteed.
Tichitarisa kumberi, yedu silica sol investimendi yekukandira fekitori iri kuwedzera yayo hybrid process line-inobatanidza pedyo-net-shape casting ine akawanda-axis milling mune imwechete setup. Izvo zvinobvisa zvikanganiso zvekugadzirisa zvakare uye zvinocheka yakazara kutenderera nguva ne37% kune zvikamu zvakaita se hydraulic manifold blocks. Precision haina kumira. Nesuwo hatisi.
