Kana vanhu vazhinji vakanzwa 'stainless simbi yekukanda zvikamu zvekudyara,' vanofananidzira chinhu chinopenya zvakakwana, chisina gwapa. Ndiwo mufananidzo wekushambadzira. Chokwadi chiri pauriri hwekutanga kutaurirana nguva dzose pakati pesimbi, geometry, uye mutengo. Ihwo hunyanzvi chaihwo hausi hwekungoita kuti hutaridzike - huri mukufanotaura kuti simbi ichayerera sei mugomba receramic, uko shrinkage ingavanda, uye giredhi ripi re316L rinonyatsoita sezvakatsanangurwa mushure mekupisa kupisa. Ndakaona madhirowa akawandisa apo mugadziri akatsanangura kushivirira kwekudyara kwekudyara achifungidzira kuti kwakafanana nekugadzira, kusaziva kuti maitiro ane mitemo yawo yemutambo.
Iyo Shell Game: Kupfuura Kungofanana Mold
Ngatitaure nezvedeko. Ndiwo moyo wekuita, uye uko zvitoro zvakawanda zvinocheka makona. Goko rakakodzera harisi kungonyudzwa slurry nejecha. Iri nezve layer count, stucco grit kufambira mberi, uye inodzorwa yekuomesa nharaunda. Ndinoyeuka bhechi rezvimwe zvigadziriso zvemugungwa apo takava nekamwe kamwe humidity spike. Makungu ainzwa akaoma kusvika pakubata, asi panguva yekudonha, takawana micro-cracks. Zvakaguma nei? Kupedzwa kusinganzwisisike pamakaseti aingoratidza panguva yekuyedzwa kwekumanikidza. Ndiko kufoira kwausingagone kuona neziso. Yakandidzidzisa kuremekedza gwaro rekudzora mamiriro okunze sezvakaita mushumo wesimbi.
Apa ndipo pane ruzivo nezvinhu zvakaita se Stainless simbi yekukanda mari yekukanda zvikamu yemakemikari pombi impellers inova yakakosha. Iyo goko rinoda kutsungirira kupisa kwekupisa kwe17-4PH yakanyungudutswa, inodururwa pane imwe tembiricha uye inoita zvakasiyana pane, toti, 304. A generic shell recipe inotungamira kune inclusions kana pamusoro pepitting. Iwe unokudziridza kunzwa kwacho - ruzha rwunoitwa negoko kana rakadzvanywa pamatanho akasiyana rinokuudza zvakanyanya kupfuura rimwe bhuku.
Ndakashanda nevatengesi vanozvirumbidza nezve otomatiki muchivakwa chegomba. Yakanakira kuenderana pakumhanya kwepamusoro-vhoriyamu. Asi kune dzakaomarara, dzakaderera-vhoriyamu zvikamu-seyakajairwa vharuvhu muviri ane akabatanidzwa mukati mechenera-hapasati pasisina chinotsiva nyanzvi ine hunyanzvi inosimbisa nemaoko nzvimbo dzisina njodzi nekuwedzera slurry dips. Ndiyo nuance yausingawani mubhurocha.
Material Haisi Ingori Chete Chete
Kutsanangura CF8M kana 316 isina tsvina padhirowa ingori kutanga. The melt practice ndiyo zvese. For corrosion-resistant Stainless simbi yekukanda mari yekukanda zvikamu, kunyanya yekumahombekombe kana yemishonga yekushandisa, unoda kudzora kwakasimba pamusoro pezvinhu zvakaita sekabhoni, sarufa, uye ferrite zvemukati. Kutsauka kudiki pachiyero kunogona kushandura kukanda kwakanaka kuita hutsinye hwekuora mushure mekutambisa kana kuratidzwa kune chlorides.
Isu takanga tine chirongwa kamwe chete che sensor housings mune desalination plant. The spec was standard 316. Takaendesa zvakasangana neASTM standard. Vakakundikana mumunda mukati memwedzi mitanhatu nekuda kwekuora kwemukova. Tinodzidzei? Iyo giredhi yakajairwa yakanga isina kukwana kune iyo chaiyo, yakaoma microenvironment. Isu taifanira kuchinjira kune super duplex giredhi yekutsiva batch. Zvino, pandinoona dhirowa, ndinogara ndichibvunza nezve nharaunda chaiyo yekushanda, kwete kungodaidzira kwezvinhu.
Iri isimba rema foundries anobata akasiyana alloys. Chitoro chinongoita zvakajairwa tsvina chinogona kupotsa izvi. Nzvimbo yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), neruzivo rwavo rwakanyorwa mu special alloys senge nickel-based, ingangove neyakaomesesa kunyungudika uye mhando yekudzora mapuroteni. Kushanda neaya anonyengerera alloys anomanikidza chirango chinobatsira kunyangwe akajairwa magiredhi asina tsvina.
Kunyengedza kweAs-Cast Kupera
Pane imwe pfungwa isiriyo yekuti kuisa mari pakudyara kunopa kupera kwekugadzirira-kushandisa. Iyo as-cast surface inogona kuve yakanaka, kazhinji yakatenderedza 125 Ra, asi kashoma iyo yekupedzisira nzvimbo. Chero nzvimbo yekuisa chisimbiso, kumeso kwekubatana, kana dhayamita yakaoma inoda machining. Iko kukosha chaiko kuri pedyo-net-shape. Iwe uri kuderedza machining nguva uye kutambisa zvinhu.
Dambudziko nderekupa zvakakwana machining stock munzvimbo dzakakodzera pasina kuita kuti kukanda kuwedzere kurema kana kugadzira nyaya dzehuremu panguva yekusimba. Ndakagadzira machina uko stock yanga isina kuenzana zvekuti chishandiso chakataura pane yekutanga kucheka, chichiratidza nzvimbo yakaoma pazasi. Izvozvo zvinowanzonongedza kusingaenderane kutonhora kweyero muchikamu ichocho cheforoma. Iyo inyaya yekukanda inoratidza kumusoro kwemuchina nhanho, kudzima mutsara pakati pemaitiro maviri aya.
Ichi ndicho chikonzero kubatanidzwa kwekukanda uye CNC machining pasi pedenga remba, sekuratidzwa kwekuita kweQSY, mukana mukuru. Chikwata chekugadzira chinogona kudyisa zvakananga kune yekutanga: Isu tinogara tichirova nzvimbo yakaoma pano, kana Iyi flange iri kukanganisa panguva yekurovera. Iyo foundry inogona ipapo kugadzirisa gating kana kutonhora maitiro. Inoshandura ketani yekugovera kuita loop yemhinduro.
Apo Kuoma Kunoruma shure
Investment casting inotengeswa pakukwanisa kwayo kugadzira maumbirwo akaomarara. Ichokwadi, asi hazvisi zvese zvakaoma kunzwisisa zvakaenzana. Kwakadzika, kwakamanikana idambudziko. Vanogona kuteya slurry, zvichitungamira kune shell inclusions, kana kudzivirira kwakaringana kuyerera kwesimbi. Ndinoyeuka chimwe chikamu chaitaridzika zvakanaka pamuenzaniso weCAD-chivako chereti mukati meimba. Runako. Asi chaive chinotyisa chemugadziri wemagoko. Ceramic core yaidiwa yaive isina kusimba zvisingaite. Mutengo wegoho wakaipa.
Dzimwe nguva, iyo yakangwara kufamba ndeye kurerutsa kukanda uye muchina iyo yakaoma yemukati chimiro. Kana kuti patsanura chikamu muzvikamu zviviri kuti zvisungirwe. Izvi zvinoda kumashure-uye-mberi nemugadziri, izvo zvisingatarisirwe nevatengi vakawanda. Ivo vanoda iyo CAD faira yakatorwa se-iri. Iyo yakanaka foundry ichatanga iyo hurukuro, kunyangwe ingagona kurasikirwa nekotesheni. Inoponesa munhu wese kubva mukukundikana pasi pemutsara.
Iyi dhizaini yekugadzira-yekugadzira (DFM) nhaurirano yakakosha. Ndiko kwaunoona kana mutengesi achingotora-odha kana shamwari yechokwadi. Kambani ine makore makumi matatu mukukanda uye kugadzira, seyataurwa QSY, ingangove yakavaka iyi kuraira kugona. Vakaona zvinoshanda uye izvo zvinoputsika, mune zvemari uye zvesimbi.
Mutengo Wechokwadi: Goho ndiMambo
Mutengo weyuniti pakukasa ivanity metric. Mutengo chaiwo uri mumutengo wakazara weprojekiti, iyo inodzorwa negoho. Mutengo wakachipa weyuniti ine 50% goho nekuda kweporosity kana kukanganisa igomba remari. Unobhadhara zvimedu, gungano rakanonoka, uye kutakura mhepo yekukurumidzira kuti utsive.
Kuvaka chiyero chegoho chakavimbika che Stainless simbi yekukanda mari yekukanda zvikamu inobva pakudzora zana diki diki: tembiricha yejekiseni yewakisi, nguva yekubika goko, kumhanya kwekudira, dhizaini yekugezera. Hazvina kunaka. Iwo logbooks, process control charts, uye dzimwe nguva, intuition. Iwe unotanga kuziva kunhuwa kwegoko rakabikwa zvakanaka rinopesana nerinenge richiri kubata unyoro.
Goho repamusoro nderokutaurawo nekuvimbika. Inyanzvi inowanikwa inokuudza kana chimiro chiri panjodzi huru yemaitiro avo. Ndoda kunzwa kuti tinogona kuita izvozvo, asi isu tinokurudzira kuwedzera 0.5mm radius yekuvandudza kuzadza padanho rekutora pane kunzwa kuti tine 30% chirahwe chiyero pachinhu ichi mushure mekushandisa. Kutendeseka ikoko, kwakazvarwa kubva mumakumi emakore ekushanda, ndiko kunoparadzanisa mubatsiri wehunyanzvi kubva kune mutengesi wezvigadzirwa. Inoshandura maitiro kubva mubhokisi dema kuita yekudyidzana engineering kuedza, uko uko ukoshi chaihwo mukukanda mari.
