Uma uzwa 'ukusakazwa kwesihlabathi sesethi yomoya', isithombe esiseduze ngokuvamile singesinye nje esihlukile sokusakaza isihlabathi, mhlawumbe ukuhlanzeka kancane. Lowo umbono oyiphutha wokuqala. Akukhona nje ukusebenzisa umoya ukwelapha i-binder. I-nuance yangempela, kanye nokungagwegwesi lapho izitolo eziningi zikhubeka khona, isekuxhumaneni phakathi kokusebenza kabusha kwengxube yesihlabathi, umswakamo wasendaweni esitezi sesitolo ngalolo suku, kanye nesikhathi esikhethekile se-binder catalyst. Kuyinqubo ezwakala ithethelela kuze kube ingekho ngokuphelele.
I-Core Mechanism kanye Nokugaya Kwayo Kwansuku zonke
Umgomo uqondile: i-synthetic resin binder ixutshwe nesihlabathi esomile se-silica, bese kwethulwa i-catalyst ewuketshezi ukuze kuqalwe inqubo yokwelapha. Igama elithi 'isethi yomoya' livela eqinisweni lokuthi lilapha ekamelweni lokushisa uma selifakwe umoya. Kodwa nakhu okubambekayo—isikhathi somsebenzi, noma 'impilo yasebhentshini', izwela ngesihluku. Ehlobo, ngokuswakama okuphezulu, imiksi yakho ingase iqale ukumisa emizuzwini emi-4 isicaba, iguqule iqoqo eliphelele libe yizigaxa, elingenakusebenziseka ngaphambi kokuthi lifinyelele ngisho kufulaski wesikhunta. Ukomisa kwasebusika kunganwebeka ngaleso sikhathi, kubeke engcupheni isikhunta esibuthakathaka uma uphuthuma ukuhlubula iphethini. Uhlala ulungisa ama-catalyst ratios ngomuzwa nolwazi, hhayi nje ngeshidi ledatha.
Sifunde lokhu kabuhlungu ekuqhutshweni kwezindlu zamaphampu zeklayenti. I-spec idinga ukuqedwa okuhle kwendawo emigwaqweni yamanzi yangaphakathi, ukwenza air set isihlabathi cast ukukhetha ekahle phezu bendabuko isihlabathi green. Usuku lokuqala lwahamba kahle. Ngosuku lwesibili, kwangena indawo engaphambili, umswakama wanda, futhi asizange sikunxephezele. Umphumela? Uchungechunge lwesikhunta esinezindawo ezintekenteke, eziphukayo ezidluliselwe ngqo kuma-castings. Ngamunye kwaba yizicucu. Izindleko zazingekho nje ngensimbi; bekusesikhathini esilahlekile kanye nokuhlela kabusha okushubile komugqa wokukhiqiza.
Yilapho ikhono langempela lilele khona. Kuyinqubo ethinta inhliziyo. Umbumbi ovuthiwe uzobamba inhlabathi exubile egcwele isandla, ayikhame, futhi ahlulele ukuqala kokwelapha ngokushisa okukhiqizwa kanye nendlela okuphuka ngayo. Alikho ithuluzi elingabuyisela lelo ngesivinini phansi. Inzuzo, uma uyihlaba esikhonkosini, iwukunemba okukhethekile kobukhulu kanye nokuqedwa okungaphezulu okuvamise ukudinga ukwenziwa kwemishini okuncane, okuyi-godsend yamajiyometri ayinkimbinkimbi.
Ukuhambisana Kwezinto ezibonakalayo kanye ne-QSY's Niche
Le nqubo akuyona eyazo zonke izinsimbi. Ikhanya ngama-alloys athambekele ekuphenduleni kwegesi noma adinga ama-gradient anembile ashisayo. Sibe nempumelelo enkulu ngensimbi eyi-ductile nezinsimbi ezine-alloy ephansi. Isihlabathi esomile, esiboshwe ngamakhemikhali sinciphisa ukukhiqizwa kwegesi emswakameni, sinciphise amaphutha e-pinholing. Kodwa-ke, kuma-high-chromium stainless steels noma ama-superalloy, umdlalo uyashintsha. Ukugcina ukushisa kwesikhunta kuhlukile, futhi ukuhlukana kwe-binder ngezinye izikhathi kungase kuholele ku-carburization yangaphezulu uma ungaqapheli ukubunjwa kwesihlabathi esibheke.
Lokhu kuhlangana ngqo nobungcweti be-Foundry efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngeminyaka yabo engamashumi amathathu ekulingiseni nasekukhiqizeni imishini, bayaqonda ukuthi le nqubo iyingxenye yempi. Inkampani efana ne-QSY, ebala ukubumba igobolondo, ukutshala izimali, nokusebenza ngama-alloys akhethekile afana nalawo asekelwe ku-nickel, ingasondela. air set isihlabathi cast ngokuqonda okucacile kwemikhawulo yayo kanye nama-synergies. Isibonelo, i-valve eyinkimbinkimbi yensimbi engagqwali e-duplex ingase iqale njengokusakazwa kwesihlabathi sesethi yomoya ukuze ihlanganise umnyombo wayo kanye nokuma okuyinhloko, bese ithuthela ezitolo zabo ze-CNC ukuze zibheke ngokunemba okuyisicefe nokubhekela phansi. Inqubo yokusetha umoya ibanika isimo esiseduze nenetha ngobuqotho obuhle, ukunciphisa imfucuza ebizayo ye-alloy ngesikhathi somshini.
Ngikhumbula iphrojekthi yokufakwa kwebanga lasolwandle lapho okokusebenza bekuyingxube ye-nickel yethusi ecacisiwe. Isihlabathi esiluhlaza besiphumile ngenxa yokukhathazeka komswakama. Ukufakwa kwezimali ezitshaliwe kuye kwanda kakhulu futhi kubiza usayizi wengxenye. I-air set yayiyindawo emaphakathi ekahle. Ukhiye kwakuwukwenza isihlabathi esibheke ngokwezifiso-ingxube esekwe ku-zirconia-ngokumelene nephethini ukuvimbela ukusebenzisana kwesikhunta sensimbi, kuyilapho kusetshenziswa i-silica evamile yesihlabathi esisekelayo. Kwakuyindlela ehlanganisiwe eyakhelwe ukusebenza okuhlukahlukene.
Umthwalo Womenzi Wephethini
Le nqubo ayinasihawu ngekhwalithi yephethini. Noma iyiphi i-undercut, noma iyiphi i-backdraft encane ongayithola esihlabathini esiluhlaza, izokhiya iphethini kusikhunta sesethi yomoya. Isibopho se-resin siqinile. Sisebenzisa ama-engeli asalungiswa azwakala edlula kakhulu iso likachwepheshe—ngokuvamile ama-degree angu-3 ubuncane endaweni eqondile. Impahla yephethini nayo ibalulekile. Ukhuni lungasonteka ngokusabela kwe-exothermic kwe-resin ephilisayo ngokuhamba kwesikhathi. Sishintshele ku-high-density polyurethane noma amaphethini ensimbi kunoma yikuphi ukukhiqiza okungaphezu kwezingcezu ezingu-50. Izindleko zokuqala ziphakeme, kodwa ukungaguquguquki kanye nesikhathi esincishisiwe sokulungisa iphethini kuyayikhokhela.
Ukukhipha umoya kungobunye ubuciko obucashile. Isikhunta siqinile. Awukwazi ukuthembela ekungeneni kwesihlabathi kuphela ukuze udedele amagesi ngesikhathi sokuthela. Sengeza iziteshi zokungenisa ingcaca eziqoshwe endaweni ehlukanisayo noma sisebenzisa ama-wax okukhipha umoya kuphethini eshile. Ukuthola lokhu okungalungile kuholela ekulahlekeni noma ekuvuvukeni kobukhulu bokuphonsa, amaphutha atholakala kuphela ekuhlolweni kokugcina.
Okungokoqobo Kwezomnotho Nokukhethwa Kwenqubo
Ngakho ukhetha nini? Akukona okuzenzakalelayo. Ezingxenyeni zensimbi ezimpunga ezilula, ezinomthamo ophezulu, isihlabathi esiluhlaza siyashesha futhi sishibhile. Ngobucwebe obuyinkimbinkimbi noma ama-turbine blades, uzotshala imali. Ukusakaza isihlabathi sesethi yomoya ithatha indawo ephakathi nendawo ebalulekile: izingxenye eziphansi kuya kwezimaphakathi zezingxenye ezidinga ukuqedwa okungcono nokubekezelelana kunesihlabathi esiluhlaza, kodwa zikhulu kakhulu noma zilula ngokwejometri ukuze kuthethelelwe umzila ogcwele wokutshala imali. Cabanga ngobakaki benjini, amakesi egiya, imizimba emikhulu yamavalvu, noma ihadiwe yezakhiwo.
Isibalo sezomnotho sihlanganisa izindleko zokuhlanganisa, eziphawulekayo, kodwa zisisusa ngokunciphisa abasebenzi begumbi lokuhlanza kanye nezibonelelo eziphansi zomshini. Ukonga u-2mm wesitoko nxazonke ekufakweni kwensimbi engu-100kg kuhumusha kube amahora amancane esikhungweni sokugaya. Kumkhiqizi ohlanganisiwe ofana ne-QSY, lokhu kubuka okuphelele—kusuka ku-Foundry kuya engxenyeni eqediwe yomshini—ilapho inani langempela lenqubo lithathwa khona. Ibavumela ukuthi bacaphune ngokuncintisana engxenyeni eqediwe, hhayi nje ukulingisa okungahluziwe.
I-takeway? Kuyithuluzi lochwepheshe. Idinga ukuhlonishwa kwamakhemikhali kanye nezici zemvelo. Ngeke kuthethelele ukunganaki. Kodwa uma isetshenziswa engxenyeni efanele, ngokusekelwa okufanele kusukela ekwenzeni iphethini ukuya emisebenzini yokusakazwa kwangemuva, ikhiqiza imiphumela okunzima ukuyihlula. Kumayelana nokuhlanganisa inqubo kumjikelezo wokuphila womkhiqizo, hhayi ukuphoqelela umkhiqizo enqubweni evamile. Lokho ukwahlulela okuvela ekuboneni kokubili impumelelo yayo ekhazimulayo kanye nokwehluleka kwayo okungcolile, okubizayo phansi kwesitolo.
