Mukamva 'opanga zitsulo zotayira,' anthu ambiri amalumphira molunjika ku chithunzi chodziwika bwino cha zitsulo zolemera, zotuwa, zophimba, zomangira injini, ndi anthu omwe amakayikira nthawi zonse. Ndilo lingaliro lolakwika loyamba. Kwenikweni, mphambano ya chitsulo chachitsulo ndi kuponya ndalama Njira, yomwe nthawi zambiri imatchedwa njira yotayika ya sera, ndi malo omwe amafunikira mtundu wina wa kulondola. Sikuti kungothira chitsulo chosungunuka; ndi kulamulira khalidwe lake mkati mwa chipolopolo zadothi kukwaniritsa geometries mchenga kuponyera sangakhoze kukhudza. Mashopu ambiri amadzinenera kuti ali ndi mwayi pano, koma kusiyana pakati pa kunena ndi kupereka mosadukiza ndi komwe kuli nkhani yeniyeni.
Zododometsa Zakuthupi: Chifukwa Chake Ductile Iron Si Yankho Nthawi Zonse
Tiyeni tikambirane kusankha zinthu. Vuto lalikulu ndikungotchula chitsulo cha ductile pazovuta zilizonse kuponya ndalama ntchito, poganiza kuti mawonekedwe ake a graphite amatsimikizira kulimba. Nthawi zambiri zimatero, koma ndawonapo mapulojekiti akusokonekera poyang'ana mawonekedwe a kulimba kwa shrinkage. Kwa mipanda yopyapyala, yowoneka bwino - ganizirani nyumba ya valve yamadzimadzi yovuta yokhala ndi ngalande zamkati-chitsulo chowongolera bwino cha imvi (monga Kalasi 35 kapena 40) nthawi zina chimatha kudzaza nkhungu modalirika, popanda chiopsezo chochepa cha micro-shrinkage porosity mu ngodya zolimba. Chisankhocho chimadalira pa kupsinjika kwa gawoli komanso kukwera kwa ukadaulo wa foundry.
Tinaphunzira izi kupyolera mu kubwereza kopweteka, kwa miyezi yambiri kwa chopopera chopopera. Wothandizira anaumirira pa ductile iron kuti asatope ku dzimbiri. Magulu atatu oyambilira anali ndi zolakwika zokhazikika pamizu ya tsamba. Pambuyo posanthula zitsulo ndi kukambirana kosawerengeka, tinaganiza zosinthira kuchitsulo champhamvu kwambiri cha imvi chokhala ndi zowonjezera zowonjezera. Sinali buku loyamba kusankha, koma linathetsa vuto la chakudya ndikukumana ndi zomwe zimachitika. Wothandizirayo anali wokayikira mpaka kuyezetsa kutopa kunabweranso. Kodi tikuphunzirapo chiyani? Tsamba lazinthu ndi poyambira, osati mapu omaliza.
Apa ndipamene zomwe wopanga amapanga nthawi yayitali zimawonekera. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zake 30 zomwe zakhala zikusewera, zikanakumana ndi mphambanozi mobwerezabwereza. mbiri yawo kuphatikizapo chitsulo chachitsulo, zitsulo, ndi zosakaniza zapadera zimasonyeza kuti amayenera kupanga ndondomeko yosiyana ya banja lililonse. Kugwiritsa ntchito ma aloyi opangidwa ndi faifi tambala kumakuphunzitsani za kuwongolera kutentha, maphunziro omwe amawongolera momwe mumayendera kutentha kothira ndi mapindikidwe ozizira achitsulo.
Njira Tightrope: Kuchokera Pachitsanzo kupita ku Shell Kutsanulira
The sera chitsanzo siteji ndi mwachinyengo yosavuta. Za chitsulo chachitsulo, yomwe imakhala ndi kutentha kwakukulu kothira kuposa aluminiyamu koma yocheperapo kuposa ma superalloys ena, mapangidwe a sera ndi jekeseni ayenera kulinganiza kukhazikika kwa dimensional ndikuchotsa mosavuta. Chitsanzo chomwe chimasokonekera pang'ono m'nyumba yosungiramo zinthu zachilimwe chikhoza kusokoneza kulolerana komaliza. Nthawi ina tinataya kupanga kwa sabata chifukwa sera yatsopano imachita mosiyana ndi chinyezi, zomwe zimapangitsa kuti zowotcherera pamisonkhano zovuta zilephereke pogwira.
Kenako pamabwera nyumba ya zipolopolo. Dongosolo la ceramic slurry ndi stucco lachitsulo liyenera kupirira kugwedezeka kwa kutentha ndi kukakamizidwa kwa ferrostatic popanda kumanga kapena kupanga mitsempha. Ndimakonda chovala choyambirira cha silika chosakanikirana kuti chikhale chokhazikika, koma ndi cholimba kwambiri. Masitolo ena amalumbirira ufa wa zircon. Palibe njira yabwino koposa zonse; ndi kugwirizana pakati pa crack resistance, collapsibility post-cast, ndi mtengo. Wopanga wabwino wakonza izi pakukula kwa gawo lawo komanso kuchuluka kwa kulemera kwake.
Gawo la dewaxing ndi kuwombera ndikofunikira. Steam autoclave dewaxing ndiyofulumira, koma pophatikiza sera yolemera, kuwotcha kwamoto kungakhale bwino kupewa ming'alu ya zipolopolo. Chigoba chowotchedwa chimayenera kukhala ndi zero yotsalira kaboni chitsulo chikachigunda, kapena kuwonongeka kwapamtunda kumatsimikizika. Ichi ndi chipata chabata, chosawoneka bwino. Mumangodziwa kuti munalephera mutatha kuwomberedwa, chifukwa chake ndondomeko zoyendetsera mbiri ya kutentha kwa ng'anjo ndizofunikira monga chemistry yosungunuka yokha.
Kuphatikiza Machining: The Make-or-Break Handoff
Ichi mwina ndiye chosiyanitsa chachikulu cha wopereka mayankho owona. A wopanga zitsulo zoponyera ndalama zomwe zimaperekanso m'nyumba CNC makina, monga zowunikira za QSY patsamba lawo https://www.tsingtaocnc.com, amathetsa mutu waukulu wogwirizana. Chitsulo choponyera, makamaka magiredi okhala ndi ma graphite ambiri, makina osiyanasiyana kuposa chitsulo. graphite imagwira ntchito ngati mafuta, koma imapanganso fumbi lopweteka lomwe limavala zida.
Kukhala ndi magulu oponya ndi kupanga pansi pa denga limodzi kumatanthauza kuti okonza makinawo atha kubwereranso kumalo oyambira. Atha kunena kuti, Flange iyi imakhala yokulirapo ndi 0.5mm mbali imodzi, mutha kusintha mawonekedwe kapena kutsanulira? Kapena, Kuuma kwa gululi ndikusiyana, kupangitsa moyo wa chida kukhala wosadziwikiratu. Ndemanga zachidulezi ndizofunika kwambiri pakuwongolera mosalekeza. Imasintha ubale wa ogulitsa kukhala mgwirizano.
Ndikukumbukira projekiti yomanga magiya pomwe ma as-cast datum anali ongokwanira kugwedeza, koma ma bore omaliza adapangidwa. Chifukwa makinawa amachitidwa kunja, pamakhala mikangano yosalekeza ngati kusalinganiza bwino ndi vuto losokoneza kapena vuto la makina. Anali masewera apamwamba olakwa. Kubweretsa njira zonse mkati kumathetsa izi. Mtengo wa malo opangira makina ndiwokwera, koma mtengo wa mikangano yosathetsedwa nthawi zambiri imakhala yokwera.
Pamene Ma Aloyi Apadera Amadziwitsa Zochita Zachitsulo
Ndizofunikira pamene maziko ngati QSY amalemba zopangidwa ndi cobalt ndi zitsulo zopangidwa ndi nickel pambali chitsulo chachitsulo. Kugwira ntchito ndi zinthu zachilendozi kumapangitsa kuti pakhale kuwongolera mopambanitsa pakuwongolera njira - kusungunula kutentha kwambiri, kutentha kwa zipolopolo, kuthamanga kwachangu, kuzizirira kwapambuyo poponyedwa mumlengalenga woteteza. Chilango chimenecho chimabwereranso ku dipatimenti yachitsulo. Ndondomeko zoyendetsera crucible, kuchuluka kwa kutentha kwa kutentha, kukhwima pakuchotsa slag - zonsezi zimakwezedwa.
Mumayamba kugwiritsa ntchito statistical process control (SPC) kuti chitsulo chanu chisungunuke osati chifukwa kasitomala akufuna, koma chifukwa mukuchita kale madongosolo a aerospace alloy. Izi mtanda pollination wa miyezo ndi zobisika mwayi. Kuponyedwa kwachitsulo sikungafune mpweya wophimba argon, koma malingaliro olembera mozama kusintha kulikonse amakhazikika mu chikhalidwe cha gulu. Imakweza pansi pazinthu zonse.
Zowona Zazaka Zoposa 30
Ulamuliro ngati zaka 30, monga tafotokozera m'mawu oyambilira a QSY, sikungotengera malonda. M'nkhaniyi, zikutanthauza kuti alimbana ndi mabizinesi angapo, awona zitsulo zikubwera ndikupita, ndipo ali ndi chidziwitso chakuya chachinsinsi. Zimatanthawuza kuti ali ndi zida zamapateni zomwe zasinthidwa kangapo, kusinthidwa kulikonse ndi phunziro lomwe aphunzira. Zikutanthauza kuti mwina atsanulira mamiliyoni a mapaundi achitsulo, ndipo awona chiwonetsero chilichonse chotheka.
Izi zikutanthawuza kufulumira kuthetsa mavuto. Choyambitsa chatsopano chikhoza kuwona cholakwika ndikudutsa pamndandanda wamabuku. Munthu wodziwa zambiri amatha kuyang'ana mawonekedwe a macro-structure, kumva zotsalira za zipolopolo, ndipo nthawi yomweyo amakayikira, mwachitsanzo, kusagwirizana kwa kuzizira kwapakati pa nthiti ndi kukoka zigawo za nkhungu. Chidziwitso chimenecho, chobadwa mwa kubwerezabwereza, chimapulumutsa nthawi ya kasitomala ndi ndalama. Ndilo chuma chosawerengeka.
Pomaliza, kusankha a wopanga zitsulo zoponyera ndalama ndi za kudalira chiweruzo chawo monga zida zawo. Ndizokhudza kupeza bwenzi lomwe limamvetsetsa kuti mawuwa akuphatikiza zisankho zingapo zovuta, kuyambira kusankha aloyi ndi kapangidwe kake mpaka ku chemistry yachipolopolo ndi kukonza pambuyo poponya. Cholinga si gawo chabe lomwe limakumana ndi zosindikizidwa; ndi gawo lomwe limachita modalirika, batch after batch, ndi sewero laling'ono pakati. Ndiko kutulutsa kwenikweni kwa opareshoni yanthawi yake.
