Xa umntu ebuza ngexabiso elilahlekileyo lokuphosa iwax, uninzi lwababoneleli, kuquka nathi, ngokwethuku bacinga ngokunika ireyithi yekhilolo nganye. Leyo yi-shorthand yoshishino, kodwa kulapho ukungaqondi kakuhle kokuqala kwenzeka. Ixabiso alikho malunga nobunzima bentsimbi; imalunga nayo yonke into ongayiboniyo kwifayile yeCAD. Ndichithe iminyaka eQSY (Qingdao Qiangsenyuan Technology Co., Ltd.), kwaye isifundo sokuqala sesokuba umothuko womxhasi kwisicatshulwa sokugqibela uhlala uvela kolu kwenziwa lula kakhulu. Babona inxalenye ye-5kg yensimbi engenasici kwaye balindele iindleko zomgca. Inyaniso kukuba, i ixabiso lokuphosa wax elilahlekileyo kuba elo candelo lingajiwuzisa i-300% ngokusekelwe kwizinto abangaziqwalaselanga okwangoku.
Apho Iindleko Zokwenyani Zifihla KwiNkqubo
Masichithe abaqhubi beendleko ezingabonakaliyo. Isigaba sepateni ye-wax siyakhohlisa. Ijiyometri entsonkothileyo yangaphakathi inokufuna i-wax cores enamacandelo amaninzi okanye i-wax cores enyibilikayo, enyusa ixabiso lesixhobo phambi kokuba kugalelwe intsimbi enye. Oku asikokwenza umatshini apho udwelisa nje umendo; Apha, lonke udonga olusezantsi kunye nolubhityileyo lufuna isicwangciso se-wax, indibano, kunye nokwakhiwa kweqokobhe. Ndikhumbula iprojekthi ye-pump impeller apho isicatshulwa sokuqala sasisekelwe kwisixhobo esiqhelekileyo se-wax. I-tweak yomthengi kwiprofayili ye-blade ithetha ukuba kufuneka sitshintshele kwi-silicone i-rubber mold kwiipateni ze-wax. Iyunithi ixabiso lokuphosa wax elilahlekileyo phantse iphindwe kabini, hayi kwintsimbi, kodwa ukusuka kwinkqubo yewax enemveliso ephantsi.
Emva koko kuza iqokobhe. Iqokobhe leceramic esemgangathweni yentsimbi yekhabhoni inokufuna iileya ezisi-7. Nge-alloy esekelwe kwi-nickel ephezulu yobushushu? Ujonge kwi-9-11 umaleko, kunye nezixhobo ezithile eziphikisayo kunye namaxesha omisa alawulwayo. Umaleko ngamnye ngumsebenzi, imathiriyeli, kunye nexesha lokutshisa. Ukuba inxalenye inemingxuma enzulu, emxinwa, eqinisekisa ukuba iqokobhe eligqibeleleyo ngaphandle kwe-voids okanye iintanda liba yinto yobugcisa. Sineendawo apho ixabiso leqokobhe kwiyunithi nganye ligqithise ixabiso lezinto eziphathekayo ze-17-4PH yensimbi engenasici ngaphakathi. Oko akukhe kubonakale kwikhaltyhuleyitha elula ye-intanethi ye-kg.
I-de-waxing kunye nokudubula kubonakala ngathi ngamanyathelo acacileyo, kodwa zihagu zamandla. I-autoclave ye-steam de-waxing kunye neziko lobushushu obuphezulu bokutshisa iqokobhe libaleka iiyure. Ngamaxabiso ehlabathi jikelele amandla aguquguqukayo, oku kukubetha ngokuthe ngqo kwaye kuhlala kungalindelekanga ukuya ekugqibeleni ixabiso lokuphosa utyalo-mali. Umjikelo wesithando somlilo webhetshi yamacandelo e-cobalt alloy unokuba liziko leendleko ezinkulu, into umthengi oodola iziqwenga ezingama-50 unokungangeni ngaphakathi.
Izinto eziphathekayo: Impembelelo ecacileyo nengacacanga
Ewe, i-316L i-stainless ibiza kakhulu ngekhilogram kune-carbon steel. Nantso inxalenye elula. Inxalenye enzima yindlela izinto eziphathekayo eziziphatha ngayo. I-alloys ye-aluminiyam inexabiso eliphantsi kodwa ingaba negesi, ekhokelela kumazinga aphezulu e-scrap. I-alloys esekwe kwi-nickel njenge-Inconel 718 inobuqhetseba obubi kodwa intsebenzo entle kakhulu yobushushu obuphezulu. Iindleko azikho nje ingot; lithuba leenyembezi ezishushu ngexesha lokuqiniswa, imfuno yokupholisa okulawulwayo, kunye nesibonelelo somatshini esongezelelweyo kufuneka usishiye ngenxa yokuba awukwazi ukuqikelela ukugqwetheka ngokugqibeleleyo.
Sisebenza ngokubanzi ngeealloyi ezikhethekileyo kwi-QSY. Iprojekthi yecandelo leinjini yomoya yayifuna ialloyi esekwe kwicobalt. Impahla ekrwada yayiyindleko, kodwa umqhubi wexabiso lokwenene yayiyi-post-casting heat treatment. Kwakufuneka umjikelo okhethekileyo wokufunxa isisombululo kwiziko lokufunxa ukuphumeza ulwakhiwo olufunekayo lweenkozo. Elo nyathelo elinye lokuphatha ubushushu longeze i-40% kwiindleko zokusetyenzwa. Xa ujongene nayo iqokobhe ngundo ukuphosa of superalloys, ixabiso kakhulu kwi-post-processing protocol njengoko kuphosa ngokwayo.
Izinga le-Scrap ngumbulali othuleyo walo naluphi na uhlahlo lwabiwo-mali. Kwiimilo ezilula kwi-iron ductile, sinokubetha isivuno se-95%. Ngodonga oluncinci, oluyinkimbinkimbi, i-stainless steel stainless, isivuno se-70% siyimpumelelo. Loo nto ilahlekileyo 30% ayikho nje isinyithi; yiyo yonke iwax, iqokobhe, abasebenzi, kunye namandla angena kwezo ziqwenga zingaphumeleliyo, zihlawulelwe kwixabiso lezo zilungileyo. Kulapho amava abalulekileyo. Injineli elungileyo iya kujonga uyilo kwaye iqikelele iindawo ezinengxaki-ezo ziphambuka ezibukhali ze-thermal eziya kubangela i-shrinkage porosity-kunye nomngcipheko wokowuthi kwi-QSY.
