Hazvisi zvekudira simbi chete; ndezvekutonga nhanho dzakapfava, dzakabatana apo kukanganisa mune imwe kunogona kubvisa batch yese. Matengi mazhinji anouya akagadziriswa chete pagiredhi yekupedzisira alloy-senge 316L kana 17-4 PH-izvo zvakakosha, chokwadi, asi ndicho chingori chekutanga. Mutengo chaiwo uye mhando yakatemwa kare.
Iyo Yepakati Yekuita: Kupfuura Kungodurura Simbi
Kukanda mari kwechokwadi, kunyanya yesimbi isina tsvina, kutamba kwehunyanzvi nesainzi ine hutsinye. Iyo shell mold process ndipo painotangira zvese. Ndakaona zvitoro umo mhoteredzo yekamuri ine tsvina—mwando, tembiricha—isingadzorwi, uye vanoshamisika kuti nei simba rawo regoko richisiyana. Pamusoro pezvikamu zvepamusoro-soro, taura kune marine kana chemikemikari yekugadzirisa zvikumbiro, izvo zvisinganzwisisiki muurayi. Goko harisi mudziyo chete; ndizvo zvinotsanangura kupera kwepamusoro uye kurongeka kwedimensional. Goko rakashata rinotungamira mukutsva-mukati, kupinda kwesimbi, uye kunotyisa kupedzisa mitengo inogona kupeta mutengo wechikamu.
Apa ndipo panoratidza hudzamu hwekambani. Ini ndinorangarira chirongwa chepombi impeller inoda CF8M isina tsvina. Iwo ekutanga prototypes kubva kumutengesi aitaridzika akakwana, asi akakundikana mukumanikidza bvunzo. Nyaya yacho? Micro-shrinkage. Mutengesi aishandisa yakajairika gating uye inosimuka sisitimu yesimbi isina tsvina, asi austenitic mamakisi seCF8M ane chaiyo yekusimbisa pateni. Kugadzirisa kwanga kusiri kwakanaka; yakanga iri pamusoro pekugadzirisa zvakare zvikwiriso uye kugadzirisa tembiricha yekudira zvichienderana nekupisa chaiko kwezvinhu. Iro rudzi rwe tweak rinobva kune ruzivo, kwete bhuku rekushandisa.
Vazhinji Stainless simbi yekukanda mari yekukanda makambani ichave kunze kwekugadzira maitiro avo kana chivakwa cheganda. Vanonyatsokwanisa, zvisinei, vanochengeta zvose mumba. Zvinovapa kutonga. Paunoshanyira nzvimbo, usangotarisa pachoto. Kumbira kuona majekiseni ejekiseni rewakisi, matangi anotsvedza, zviteshi zvekushandisa zvestucco. Hutsanana uye kurongeka (kana kushaikwa kwayo) ikoko kunokuudza kupfuura chero chitupa chemhando pamadziro.
Material Nuances uye Special Alloys Factor
Simbi isina tsvina imhuri, kwete chinhu chimwe chete. Iyo machining uye kupisa kurapwa mhinduro ye304 inyika kunze kwe15-5 PH. Musungo wakajairika kuvabata vese zvakafanana mumashure ekukanda maoparesheni. Ndakashanda na Stainless simbi yekukandira mari mutengesi pane muviri wevharuvhu mu duplex simbi 2205. Kukandira kwaive kwakanzwika, asi vakashandisa mhinduro annealing cycle yaireva 316. Yakaparadza chiyero cheferrite-austenite uye kusagadzikana kwekuora. Taifanira kubvisa zvakawanda. Icho chaive $40,000 chidzidzo chemetallurgical chaiyo.
Ichi ndicho chikonzero kutaurwa kweakakosha alloys senge nickel-based kana cobalt-based ari mupotifolio yekambani chiratidzo chakakosha. Zvinoratidza kuti vakafanirwa kutarisana nezvimwe zvinonetsa kunyungudika, kudurura, uye kupisa-isostatic-pressing (HIP) zvinodiwa. Kana vachikwanisa kubata Hastelloy C-276, ipapo kukanda 316L kufamba mupaki kwavari. Midziyo uye kuziva-sei kukwira kumusoro, kwete pasi.
Tora kambani yakafanana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Vanonyora Stainless simbi yekukandira mari padivi pegoko rekukanda kukanda uye CNC machining, uye kunyanya kudaidza cobalt uye nickel alloys. Ndiko mubatanidzwa unoshanda. Zvinondiudza kuti vangangonzwisisa kuti chikamu chakakandwa kazhinji chingori chigadzirwa chakapedzwa. Kuve nemachining mukati-mumba mukana wakakura wekudzora dimensional uye nguva yekutungamira. Iwe unodzivirira munwe-kunongedza pakati peiyo yekutanga uye chitoro chemuchina kana kushivirira kwapotsa. Kudai kwavo kwemakore makumi matatu mukukanda nekugadzira kunoratidza kuti vangangoona mazhinji emusoro wemusoro unoenderana nezvinhu uye (netariro) vakadzidza kunzvenga.
The Integration Machining Advantage
Izvi zvinotungamira kune yangu inotevera pfungwa: iyo isina musono handoff pakati pekukanda uye machining. Ihombe, kazhinji isingakoshesi kukosha. Ndakambotora imwe Stainless simbi yekuisa mari yekukanda flanges kubva kune yakatsaurirwa foundry. Kukandwa kwacho kwaive kwakanaka, asi nzvimbo dzedhamu dzemachining dzakanga dzisina kugadzirwa zvakanaka. Iyo yakaparadzana muchina shopu yakanetseka kubata iyo perpendicularity callout, zvichitungamira kune 30% yekurambwa. Dambudziko rakanga riri nyaya yekugadzira iyo yaifanira kunge yakabatwa panguva yekukanda maitiro ekuronga.
Apo iyo makambani ekukanda mari zvakare mhanyisa madhipatimendi eCNC, mainjiniya avo anofunga nezve chikamu zvachose. Ivo vanozopa zano rakapusa dhizaini shanduko kana kukurudzira kushandura mutsara wekuparadzanisa kuti ugadzire iri nani machining datum kubva pakutanga. Ivo vanogadzira gating system kwete yesimbi inonzwika chete asiwo kuti ichabviswa sei uye pachange paine maclamp marks. QSY's modhi yekupa ese ari maviri shell mold/investment casting uye CNC machining pasi pedenga remba ndiyo chaiyo mhando yesevhisi yakabatanidzwa inogadzirisa aya matambudziko akadzikama. Hazvisi zvekungorerutsira; ndezvekuvakwa-mukati simbisiro yemhando.
Iyo machining ye cast stainless ine matipi ayo. Izvo zvinhu zvinogona kunge zviri gummy, kushanda-kuomesa mamakisi senge 304 kunogona kuve nehutsinye pamidziyo, uye kuomarara kusingawirirani kwese-kukandwa nzvimbo kunogona kutungamira kune chishandiso chatter. Mutengesi akabatanidzwa anogona kunge akagadzira midziyo yekudyira, kumhanya, uye nzira dzematurusi ezvavanokandira. Irwo ruzivo rwemasangano harupo kana zvikamu zvatumirwa kune generic muchina shopu.
Quality Perception vs. On-the-Ground Reality
Zvitupa zviteki zvetafura. ISO 9001, PED, AD2000—iwo anodiwa pakuita bhizinesi muzvikamu zvakawanda, asi haavimbisi kukanda kwakanaka. Vanovimbisa hurongwa hwakanyorwa. Hunhu chaihwo huri mumaprotocol asiri ekuparadza (NDT) uye kuda kuasimbisa. Iyo kambani inoita zana muzana yedhayi yekupinda bvunzo pane ese akakosha kirasi zvikamu? Vane-mumba X-ray kana ultrasound, kana kuti vanoiburitsa kunze? Outsourcing inogona kuwedzera mazuva uye kuderedza mhinduro loop yekugadziriswa kwemaitiro.
Ndinoyeuka ndichiongorora vimbiso yakavimbiswa Stainless simbi yekukandira mari mutengesi. Mapepa avo akanga asina kunaka. Asi pasi, ndakaona mushandi ave kuda kukuya chirema pavharuvhu asina kutanga anyora kana kuwana mvumo yeQA. Chiito chimwechete ichocho chakavharisa yavo yese traceability system. Tsika yemhando yepamusoro pasi pechitoro, kupihwa simba kwevashandi kumisa mutsara, zvine basa kupfuura chitupa mukamuri yekutandarira.
Hupenyu hurefu mubhizinesi, senge QSY yemakore makumi matatu, inowanzoenderana neyakakura mhando tsika. Vakapona nekuti vanogona kunge vakagadzirisa nyaya dzehurongwa dzinoisa makambani matsva kunze kwebhizinesi. Vangangove vakaisa mari mumidziyo yakaita sema spectrometers ekuongorora chemistry uye vakamisa wakisi yavo nemabhainda kuti vaderedze zvinosiyana. Izvi hazvina kunaka, asi ndizvo zvinoita kuti kambani ivimbike.
Mafungiro Anoshanda Pakupfimbana
Saka, unoshanda sei nemakambani aya zvinobudirira? Kutanga, ipa mufananidzo wakakwana. Usangotumira mufananidzo. Taura nharaunda yekushandisa-tembiricha, kudzvanywa, midhiya, cyclic kurodha. Izvi zvinozivisa zvese kubva pakusarudzwa kwealloy kusvika pakudiwa kweHIP. Chechipiri, vhurika kune Dhizaini Yekugadzira (DFM) mhinduro. Injiniya yakanaka yekuvamba inogona kupa gadziriso kudiki kwemadziro kana shanduko yeradius iyo inovandudza zvakanyanya kukanda uye kuderedza mutengo, pasina kurasikirwa kwebasa.
Chechitatu, gadzirisa zvinotarisirwa pamusoro pekupedzisira. As-cast surface roughness (Ra) yekukandira mari yakanaka, asi haisi girazi rakagadzirwa. Kana iwe uchida Ra 1.6 pachibhorani, tsanangura iyo seyakagadzirwa pamusoro. Iyo foundry inozosiya stock zvinoenderana. Kujeka pano kunodzivirira kuora mwoyo.
Pakupedzisira, ona hukama sehukama. Mhedzisiro yakanakisa yandakawana kubva mukubatana kugadzirisa matambudziko. Paiva neimba yakaoma yataida mu17-4 PH mamiriro H1150. Makwikwi ekutanga aive nekutsemuka. Kuburikidza nekuferefeta kwakabatana — metallurgist wavo nainjiniya wedu — takaitsvaga kusvika pamubatanidzwa wekutonhodza mwero mushure mekudira uye dhizaini yekona yemukati yakapinza. Isu takagadzirisa dhizaini (kuwedzera fillet) uye ivo vakagadzirisa maitiro avo ekuzunza. Chikamu chave chiri mukugadzirwa kwemakore ikozvino. Ndiko kukosha kwekubatana nevanokwanisa Stainless simbi yekukanda mari yekukanda makambani-ivo vanova kuwedzera kwechikwata chako cheinjiniya.
Munda wakazara vanhu, asi vanokunda havasi ivo vane mawebhusaiti akanyanya. Ndivo vane matangi anodzorwa slurry matangi, in-house metallurgist, iyo yakabatanidzwa CNC maseru, uye pragmatic, kugadzirisa dambudziko pfungwa dzakakudzwa kwemakumi emakore, senge nhoroondo yekushanda inotaurwa nekambani yakaita seQSY. Iyo mhizha iri mumashoko, uye simbi inogara ichitaura chokwadi.
