Xa abantu abaninzi besiva 'iinkonzo zotyalo-mali', baba nomfanekiso wencwadana ecwebezelayo enamalungu abengezelayo, antsokothileyo. Inyani, ukugaya imihla ngemihla, kubi kakhulu kwaye kunomdla ngakumbi. Kukho uluvo olungalunganga oluqhelekileyo lokuba konke kukufikelela kwimilo ekufutshane nenetha kwaye yiyo. Kodwa elona xabiso lokwenyani, inxalenye egcina iinjineli kunye nabaphathi beentengo ebusuku, ayisiyiyo nje imilo-kukunyaniseka kwaloo milo kwizinto ezifanelekileyo, ibhetshi emva kwebhetshi, ngaphandle kwedrama. Kulapho amashumi eminyaka eziva zokusebenza, hayi nje iminyaka yamava, ziqala ukudlala.
Umdlalo weShell: Ingaphezulu kuneSanti nje
Wonke umntu kwishishini uthetha ngenkqubo yokubumba iqokobhe. Yintliziyo ye utyalo mali. Kodwa usathana uku-slurry viscosity, ubungakanani bengqolowa yesanti ye-stucco, kunye nendawo yokomisa. Ndikhumbula iprojekthi yomfuziselo weblade ye-injini apho iqokobhe lalihlala liqhekeka ngexesha lokukhutshwa kwewaxing. Ipateni ye-wax yayigqibelele, ukuyila kwakuvakala, kodwa sasilahlekelwa malunga ne-30% yeegobolondo. Umba wawungeyoyona idyasi yokuqala; yayilulawulo lokufuma ngexesha lokomiswa kweedyasi zokugcina. Inguqu encinci yexesha lonyaka besingekayihlawuleli ngokupheleleyo. Yimiba engathandekiyo, yokusingqongileyo enokuthi iphazamise ishedyuli. Ivenkile esele idlule ngamaxesha aneleyo onyaka, njengeQingdao Qiangsenyuan Technology Co., Ltd.(QSY) ngokubaleka kwayo iminyaka engama-30, kusenokwenzeka ukuba iye yabhaka ezo zifundo kwiinkqubo zazo zokusebenza eziqhelekileyo. Abakhi nje iqokobhe; balawula i-microclimate.
Ukhetho lwezinto eziphathekayo luyadibana nalapha. Awunako ukuqhwaba nje nayiphi na ingxubevange kuyo nayiphi na inkqubo yeqokobhe. Ngokomzekelo, ukugalela i-alloys esekelwe kwi-nickel ephezulu yokushisa kufuna i-shell shell refractory formulation kune-standard 316 yensimbi engenasici. Ukungahambelani kolwandiso lwe-thermal kunokubangela ukubola kweqokobhe okanye ukungena kwentsimbi. Ndikhe ndabona iindawo ziphuma zirhabaxa, umphezulu omdaka ngenxa yokuba iqokobhe lalingalungiselelwanga ubushushu be-alloy. Yingongoma echuliweyo yokusilela eyohlula i-caster yempahla kwingcali.
Apha kulapho isithembiso se-'complex geometries' sidibana nenyani yomgangatho wesiseko. Ela jelo langaphakathi lintsonkothileyo olenzileyo? Isebenza kuphela ukuba i-ceramic core inokubekwa ngokuthembekileyo kwaye emva koko isuswe ngokupheleleyo emva kokuphosa. Sakhe saba nomzimba wevalvu onepaseji yangaphakathi ebuhlungu. Ukuphosa kwakukuhle, kodwa sichithe ngaphezulu kwi-ultrasonic kunye nokususwa kweekhemikhali ezingundoqo kunokuphosa ngokwayo. Ulungile iinkonzo zotyalo-mali Umboneleli uya kufulegi oku kwangethuba, ecebisa uyilo lwe-tweaks kushicilelo oluphambili okanye ukuxoxa ngeendlela ezizezinye zobuchwephesha kwasekuqaleni.
I-alloys: Ayizizo zonke iintsimbi ezenziwe ngokulinganayo
Uluhlu lwezinto eziphathekayo-intsimbi, intsimbi, i-stainless, i-cobalt-based, i-nickel-based-ijonge ngqo kwiwebhusayithi efana ne-https://www.tsingtaocnc.com. Kodwa ukubaphatha akukho nto. Ukuphosa i-17-4 PH engenasici ukufezekisa imeko efunekayo ye-H900 ngumzekelo oqhelekileyo. Akukhona nje malunga ne-chemistry enyibilikayo; kukupholisa okulawulwayo emva kokugalela kunye nomjikelo wonyango wobushushu olandelayo. Fumana iqondo lokupholisa elingalunganga kumngundo, kwaye imvula yokuqina kamva ayizukukunika iimpawu zomatshini ozifunayo. Inxalenye inokuphumelela uhlolo olubonakalayo kodwa ingaphumeleli kuvavanyo lokukhathala.
Ukusebenza ngee-alloys ezikhethekileyo ezifana ne-cobalt-based Stellite okanye i-Inconel ezahlukeneyo ngomnye umdlalo webhola. Zihlala zikhankanywa ngokugqithisileyo okanye ukuxhathisa umhlwa. Ucelomngeni kukungabi namanzi—okanye ukungabikho kwawo. Azihambi njenge-aluminiyam. Udinga ukushisa okuphezulu okuphezulu, okugxininisa iqokobhe, kwaye ihlala ifuna amazinga okugalela ngokukhawuleza ukunqanda umkhenkce ongaphambi kwexesha kumacandelo amancinci. Uyilo lokungena luba lubaluleke kakhulu. Inkqubo yokungena engalunganga kwinxalenye yentsimbi yekhabhoni esemgangathweni inokukunika nje umngxuma wokushwabana. Kwinxalenye yealloyi ye-cobalt eyi-$500/kg, yilahleko eyintlekele. Apha kulapho ubuchwephesha be-metallurgical be foundry, hayi nje isakhono sayo sokuphosa, bubaluleke kakhulu.
Ndicinga ukuba uninzi lwabaphathi abafumana uncedo bajongela phantsi ixabiso lesiseko esibuqonda ngokunyanisekileyo ubugcisa. QSY ukukhankanya CNC Machining ngokuhambelana nokuphosa ayisiyonkonzo nje yokongeza ixabiso; luphawu lokucinga okuhlangeneyo. Bayazi ukuba bangasishiya phi isitokhwe ukuze bacoceke, ukuba uxinzelelo lokuphosa lunokuchaphazela njani ukugqwethwa komatshini, kwaye yeyiphi imiphezulu ebalulekileyo ukubamba unyamezelo. Ukuphosa inxenye yemilo ekufutshane nenethi engenakufikelelwa yinkunkuma epheleleyo. Ivenkile edibeneyo ifunda kumacala omabini enkqubo.
I-Handoff: Ukusuka kwi-Casation ukuya kwiNdawo egqityiweyo
Esi sisigaba esibhentsisa iinkqubo ezingekho mgangathweni. Inxalenye ephoswe ngokugqibeleleyo inokonakala ngokuqhushumba kwesibhamu okanye ukusika okungafanelekanga kwenkqubo yokugaya. Ndikhumbula ibhetshi yezifakelo zentsimbi engatyiwayo apho amandla okuqina kwisiphunzi sesango ayengaphantsi kwe-spec. I-casting ngokwayo yayisandi, kodwa inkqubo ye-cutoff manual yayivelise ukushisa okwaneleyo kwendawo ukuchaphazela i-microstructure. Ukulungiswa kwakuya kwi-waterjet e-abrasive okanye inkqubo ye-saw-band elawulwayo kunye nokupholisa okufanelekileyo. Yinkcukacha yokugqiba engenzi i-pitch yokuthengisa, kodwa ibulala iinxalenye.
Ukuhlolwa komgangatho yenye indawo yemigodi. Ujongene neendawo eziye zadlula kwimijikelo ye-thermal ukusuka ~ 1500 ° C ukuhla ukuya kwiqondo lobushushu begumbi. Bayashukuma. Ingxelo yokuhlola inqaku lokuqala elibanzi (FAIR) elibandakanya idatha yeCMM ayinakuxoxisana kumacandelo abalulekileyo. Kodwa nangona kunjalo, kufuneka uyazi ukuba ulinganisa ntoni. Ulwakhiwo lweDatum kumzobo wokuphosa kufuneka lusebenze. Ukulindela umphezulu ophosiweyo ukuba ube yi-datum esebenzayo yokunyamezela ukunyamezela kudla ngokucela ingxaki. Ngamanye amaxesha, kufuneka utshise i-datum yokuqala, emva koko ujonge ezinye izinto. Umboneleli otyhalela emva kwimizobo engafanelekanga uyakwenzela inceba.
Ekugqibeleni, kukho i-logistics yokuhambelana. Ngaba banokugcina ikhowudi yobushushu yentsimbi efanayo kwimveliso eqhutywayo? Ngaba banokulandeleka ukusuka kwingot ukuya kwindawo ethunyelwe ngenqanawa? Kumashishini afana ne-oyile negesi okanye i-aerospace, oku akukhethi. Yongeza iindleko kunye nobunzima, kodwa isiseko esisebenze kwelo nqanaba, mhlawumbi siyakha kwinkqubo yabo kwiminyaka, kungekhona njengengcamango yamva.
Xa ingahambi kakuhle (kwaye iya)
Ukusilela ngoyena titshala ubalaseleyo. Kwangoko ngexesha lam lokujongana nokuphosa, siye saqhuba izindlu zempompo kwi-duplex stainless eyaphuhlisa ukuqhekeka kancinci. I-chemistry yayikwi-spec, inkqubo ibonakala ingatshintshi. Emva kophando oluxabisa imali eninzi olubandakanya uhlalutyo lwelebhu yangaphandle, umoni uye walandwa kungcoliseko olungephi kwimathiriyeli yeqokobhe leceramic ehlaziyiweyo echaphazela isantya sokupholisa sasekhaya. Isisombululo yaba lulawulo olungqongqo ekufumaneni izinto zeqokobhe kunye nomjikelo wokudubula olungisiweyo. Ingongoma kukuba, umboneleli onamava unethala leencwadi loku kusilela kunye nezisombululo zabo. Baye batyala imali kwizixhobo zokuxilonga-i-spectrometers, uhlalutyo lwe-thermal, izixhobo ze-radiographic-ukuba bangafumani nje ingxaki, kodwa baqonde unobangela wayo.
Omnye umgibe oxhaphakileyo bubuxoki 'bekopi ngqo'. Uthumela isampuli egqibeleleyo kwaye ucele isicatshulwa ukuze uyiphindaphinde. Ngaphandle kweeparamitha zenkqubo yantlandlolo-ezona mathiriyeli iqokobhe, ubushushu obuthululwayo, uyilo lokungena-ucela ubunjineli obubuyela umva, hayi ukuveliswa kwakhona. Isicatshulwa sinokuba siphantsi, kodwa umjikelo wophuhliso ukuhambelana nesampulu iya kuba yinde kwaye ibiza. Kuhlala kungcono ukuqala kushicilelo kunye neemfuno zokusebenza.
Ukusonga: Izinto eziNgaphathekiyo zeNkonzo
Ngoko ke, uthenga ngantoni ngokwenene iinkonzo zotyalo-mali? Uthenga ukuqikelela. Uthenga iqabane eliye labona iipateni zewax zidilika, amaqokobhe aqhekeka, ii-alloys ziziphatha kakubi, kwaye zineenkqubo zokuthintela oko. Uthenga isigwebo ukuze wazi xa uyilo lunokuphoswa njengoko lunjalo, xa lufuna i-tweak, kwaye xa kufuneka lwenziwe ngenye indlela ngokupheleleyo.
Ayikokuba nesona sithando somlilo sikhulu okanye iirobhothi ezininzi. Imalunga nememori edibeneyo kwi-Foundry. Xa inkampani efana ne-QSY ikhankanya iminyaka engama-30, loo nkumbulo yeyona asethi yokwenyani. Kuthetha ukuba mhlawumbi bagalele i-alloy engacacanga oyifunayo ngaphambili, bayilungisile loo jiyometri ifanayo, kwaye bayazi ukuba zeziphi iikona ezingenakunqunyulwa ngokupheleleyo. Loo mbali iguqulela ngokuthe ngqo kumngcipheko ophantsi weprojekthi yakho, ii-odolo zotshintsho zobunjineli ezimbalwa, kunye nethuba eliphezulu lokuba ibhetshi yokuqala yamalungu iyasebenziseka, ingeyiyo nje inkunkuma ekhangeleka ngathi ngumzobo.
Ekugqibeleni, eyona nkonzo ingcono iziva ingenangxaki. Uthumela ushicilelo, ufumana isicatshulwa, iinxalenye zifika ngexesha, ziyalingana, ziyasebenza. Oko kuhamba ngokungenamthungo luphawu lomboneleli oye wahamba ngaphaya kokuthengisa inkqubo yokuhambisa isisombululo esithembekileyo, esinobunjineli. Ngumahluko phakathi kokuthenga i-casting kunye nokuthenga isiphumo.
