Izvo hazvina kukanganisa, asi iwo maonero epamusoro-soro anopenya pamusoro pechokwadi chechokwadi chekuvagadzira. Iyo chaiyo nyaya haingori pamusoro pezvinhu zvinokatyamadza zvezvinhu-yepamusoro-tembiricha simba, corrosion resistance-iri pamusoro pemukana wakakura uri pakati pekuva neCAD modhi uye kubata chakapedzwa, chinoshanda chikamu chisingakundikane mukushushikana. Zvikwata zvakawanda zvekutenga zvinhu zvinoona giredhi realloy, seInconel 718 kana Hastelloy C-276, uye vanofunga kuti basa rinonyanya kuitwa. Chokwadi ndechekuti, ndipo panotangira basa chairo, nemusoro chaiwo.
The Casting Conundrum: Zvose zviri muFeed
Ngatitaurei nezve kukanda mari, nzira yakajairika kune yakaoma geometries. Ne nickel alloys, haisi yekungodira simbi yakanyungudutswa mugomba receramic. Maitiro ekusimbisa inhamo kana ukasaidzora zvine hungwaru. Shrinkage muvengi. Iwe haugone kungowedzera mafeeder makuru kwese kwese; uri kubata nezvinhu zvinodhura, uye huremu hwakawandisa kazhinji dhizaini yakakosha. Ndakaona zvikamu uko yekutanga gating system dhizaini, iyo yakashanda zvakanaka yesimbi isina tsvina, yakatungamira kune njodzi yepakati shrinkage muchikamu chakakora che nickel based alloy vharafu muviri. Icho chikamu chaitaridzika chakanaka kunze, asi kuongororwa kweultrasonic kwakaratidza porous core iyo ingadai yakatsemuka pasi pekumanikidzwa. Kugadzirisa kwanga kusiri nyore tweak; zvaisanganisira kugadziridzwa patsva kwehurongwa hwekudyisa, uchishandisa simulation software kuenzanisira magradients ekupisa, uye wozoisimbisa nenhevedzano yemuyedzo inodhura inodurura.
Apa ndipo panobhadhara ruzivo kubva kune foundry yanga yakatenderedza block. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore ekukanda, vangave nemukati maprotocol eizvi. Vaisazongovimba nekuenzanisa; vangave neraibhurari yenhoroondo data kubva kune akafanana geometries, vachiziva kuti kune chaiyo madziro ukobvu shanduko mune a nickel yakavakirwa alloy chikamu, unoda chinodyisa chechiyero chedhayamita-kusvika-urefu, chakaiswa pakona chaiyo. Rudzi urwu rweruzivo rwechinyararire harwumo mune chero bhuku; inovakwa kubva kune vakakundikana uye vakabudirira kwemakore.
Iyo shell mold process pachayo yakakosha. Kuwedzera kwemafuta eceramic kunofanirwa kuenderana nealloy kudzivirira kubvarura kupisa kana kuremara kwepamusoro. Kune yakakwirira-gamma-prime alloys seIN-738, anoshandiswa muturbine blades, mold preheat tembiricha uye tembiricha yekudira ine hwindo ringangoita makumi matatu madhigirii. Zvipotsa, uye iwe unowana misruns kana yakanyanyisa kukura kwezviyo. Iyo ballet yekupisa kwakanyanya uye chaiyo nguva.
Machining: Kupi Kwekushandisa Kunofa
Kana kukanda kuri kupisa kunodzorwa, machining nickel alloys ihondo yekurwisa. Mwero wekuomesera basa unotyisa. Iwe unotora kucheka, uye zvinhu zviri pasi pechombo zvinoomesa pakarepo. Pinda nemaparamendi asiri iwo, uye hausi kucheka-urikungokwiza nekugadzira kupisa kwakakwana kuti weld workpiece kune chishandiso. Ndakadzidza izvi nenzira yakaoma pakutanga, ndichiedza kudzika dhayamita paInconel 625 shaft. Yakashandiswa yakanaka-rake chishandiso, kumhanya kwakajairwa uye mafidhi esimbi yakaoma. Mumaminiti mashoma, chokuisa chakanga chapera, uye chikamu chacho chakanga chaoma, chakapenya chaida maawa okukuya kuti chiponeswe.
Iyo nzira inopikisa-intuitive. Unoda zvakapinza, zvisina kunaka-rake maturusi, kazhinji carbide kana ceramic, ine yakaomesesa setup. Kudzika kwepasi kumhanya, kudya kwakakwira, uye kudzika kwakadzikama kwekucheka. Chinangwa ndechekupinda pasi pebasa-rakaomeswa layer kubva kune yapfuura pfuura uye kugera zvinhu zvisati zvaoma kupikisa chishandiso. Inotonhodza haisi yekutonhodza chete; iyo lubricant yekudzivirira yakavakirwa-kumusoro uye inofanirwa kuendeswa kune yakanyanya kudzvanywa ipapo pane yekucheka interface. Kunyange zvakadaro, upenyu hwematurusi hunoyerwa nemaminiti, kwete maawa. Kune yakaoma nickel based alloy impeller ichigadzirwa pa5-axis CNC, mutengo wekushandisa unogona kuva chikamu chakakosha chebasa rese.
Ichi ndicho chikonzero iyo machining kugona yakanyorwa pawebhusaiti senge QSY haisi bhokisi rekutarisa.
