Ukaona izwi rekutsvaga senge '17 4 ph investimendi yekukandira', zviri nyore kufunga kuti ingori imwe yezvinyorwa spec sheet yekupinda. Muchokwadi, ipfupi yeeseti yezvinetso uye sarudzo pauriri hwechitoro. Vazhinji vanotenga zvinhu kana kunyange mainjiniya madiki vanofunga kutsanangura 17-4 PH, kana 17-4PH simbi isina tsvina, mhinduro yekumira-imwe yekuda simba rakakwirira uye zvine mwero corrosion kuramba. Vanowanzo potsa mamiriro akaoma eH-mamiriro ekurapa kupisa-zvinova zvose. Ndakaona madhindindi achiuya achingoti 17-4 PH kuisa mari, uye ndipo panotangira nhaurirano chaiyo, uye dzimwe nguva kutemwa nemusoro.
The Core Dambudziko: Zvose Nezve Chimiro H900, H1025, kana H1100
Iwe haungokanda 17-4 PH; unoikanda uye wobva waipisa uchiibata kune imwe mamiriro kuti uwane zvivakwa zvaunoda. Iyi ndiyo forogo huru yekutanga mumugwagwa. Iyo as-cast mamiriro ndeye mhinduro annealed (Chimiro A). Yakapfava, inogoneka, asi haina yakakurumbira kunaya-yakaoma simba. Iwo mashiripiti anoitika mushure mekudzika-tembiricha kuchembera kupisa kurapwa. H900 inokupa iyo yekupedzisira kusimba simba, kusunda kupfuura 190 ksi, asi yakanyanya brittle uye bere kumuchina. H1150 inopa kusimba kuri nani uye kuramba kwecorrosion, asi iwe unotengeserana neyakakura chunk yeiyo simba repamusoro.
Kusarudza mamiriro asiri iwo echishandiso ndeyekare, inodhura kukanganisa. Ndinoyeuka purojekiti yechikamu chemugungwa apo mugadziri, akasimbiswa nesimba, akatsanangura H900. Chikamu chakapasa bvunzo dzese dzerabhoritari asi chakakundikana mumunda nekuda kwekunetsekana kwegorosi kupaza mune iyoyo chaiyo-yakaoma mamiriro. Taifanira kukanda zvakare uye kupisa zvakare kubata batch yese kuH1150, iyo yakagadzirisa nyaya yemunda asi yakanonoka chirongwa nemwedzi. Tinodzidzei? Kupokana kwekuora kwe17-4 PH kunoenderana nemamiriro ezvinhu, kwete nhamba yakatarwa.
Apa ndipo panoshanda neakawana anonzwisisa simbi, kwete kungoumba chete, hakugone kutaurirana. Shop like Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore avo Investment casting uye machining, kazhinji anowana izvi. Vaisazongodira simbi yacho voitumira. Maitiro avo anosanganisira post-casting heat treatment protocol, uye vangangoratidzira isina kukwana kumberi. Iwe unogona kuona maitiro avo kune zvigadzirwa, kusanganisira alloys akakosha, pane yavo saiti pa tsngtaocnc.com. Iri ruzivo rwakabatanidzwa rwekukanda uye kunotevera kupisa kwemafuta kunoparadzanisa mutengesi kubva kune injiniya shamwari.
Gating, Kudyisa, uye Hondo yeShrinkage
Kufamba kubva kune simbi kuenda kune mold, 17-4 PH inopa yayo seti yekukanda matambudziko. Iine kukosha kwakasimba kwekusimba shrinkage. Kana yako geting uye riser (feeder) system isina kugadzirwa zvakakwana, unowana shrinkage porosity, kazhinji munzvimbo dzekupedzisira kusimba sezvikamu zvakakora kana makutano. Ichi hachisi chirema chepamusoro chaunogona kugaya; iri mukati uye inouraya chikamu chemagetsi kutendeseka, kunyanya pasi pekuneta kurodha.
Isu takadzidza izvi kuburikidza neanorwadza, diki-batch kugadzirwa kumhanya kune aerospace actuator bracket. Iyo geometry yaive yakaoma, isina kuenzana madziro ukobvu. Mienzaniso yekutanga-yakatarisa yakatarisa yakakwana. Kuongororwa kweX-ray, zvisinei, kwakaratidza network ye micro-shrinkage mukati mepakati hub. Iyo tensile mabara akachekwa kubva munzvimbo iyoyo akatadza zvinoshamisa pazasi spec. Nyaya yacho? Yedu yakajairwa kudya kwekuverenga, iyo yakashanda zvakanaka kune 316 isina tsvina, yakanga isina kukwana kune yekusimba maitiro e17-4. Isu taifanira kugadziridza iyo yese yemiti dhizaini, tichiwedzera mamwe makuru ekusimuka uye kushandisa exothermic padding kuchengetedza simbi ichipisa kwenguva yakareba munzvimbo dzakaoma. Yakawedzera kurasikirwa kwegoho pamuti asi yakachengetedza zvikamu.
Iyi ndiyo imwe nharaunda umo ruzivo nezve chaiwo zvinhu zvine basa. A foundry's standard shell mold mold system ingangoda tweaking-pamwe imwe yakasiyana slurry magadzirirwo kana stucco-kubata zvinopisa zvinodikanwa zveiyi alloy. A generic shell mold casting nzira haina kukwana; inoda kuve nzira yakagadziridzwa kune kunaya-kuomesa simbi.
Iyo Machining Interlude: Usazvirerutsa
Heino chokwadi chinoshanda chingangoita 17-4 PH yekudyara kukanda ichasangana: inoda machining. Zvikamu zvishoma zvine mambure. Iwe une kubviswa kwegedhi, kupedzisa kwepamusoro, uye yakakosha datum machining. Uye sezvakataurwa, kuoma kwekugadzira kunosiyana zvakanyanya nemamiriro. Machining iyo yakapfava Mamiriro A yakatwasuka, asi ipapo iwe unopisa kubata, uye chikamu chinozokanganisa. Dzimwe nguva kufanotaura, dzimwe nguva kwete.
Imwe nzira ndeyemuchina mune yakaomeswa mamiriro (semuenzaniso, H900). Izvi zvinodhura, zvinononoka, uye zvine hutsinye pakushandisa. Iwe uri kutarisa kuomarara kweCNC setups, premium carbide kana kunyange maturusi eCBN, uye mitengo yakaderera yekudyisa. Mutengo wemutengo unoshanduka zvachose. Ichi ndicho chikonzero QSY yakabatanidzwa mupiro we Investment casting uye CNC machining pasi pedenga remba pane zvine musoro. Vanogona kuronga kutevedzana kwese kwekugadzira zvakazara. Ivo rough muchina muCondition A, vanosiya stock, kupisa kurapwa, vozopedzisa muchina? Kana kuti vanokanda kune yakaomesesa padyo-neti chimiro uye muchina iyo yese mushure mekuomesa? Sarudzo iyoyo inokanganisa mutengo, nguva yekutungamira, uye zvakanyanya kukosha, chikamu chekupedzisira geometry kushivirira.
Ndakapinda muzvirongwa uko machining akarimwa kune yechitatu-bato shopu isingazivikanwe yakaoma 17-4. Mhedzisiro yacho yakaraswa zvikamu nekuda kwekushata kwepamusoro pekupedzisira, madiki-akatsemuka anokonzerwa nehukasha machining, uye dimensional kusarongeka. Kuunza iyo yose kukosha ketani, kana kanenge yakakosha yekukanda-kupisa kurapa-machining nhanho, pasi pehutongi hwakarongeka ihombe yekuderedza njodzi.
Material Sourcing uye Traceability: Kwete Yese 17-4 yakaenzana
Izvi zvinogona kunzwika sechinhu chakakosha, asi mhando inotanga nekunyungudika. 17-4 PH izita reUNS (S17400), asi iwo chaiwo chemistry mitsara mukati meiyo spec inogona kukanganisa castability, kuoma, uye yekupedzisira zvivakwa. Zvinhu zvakaita semhangura, niobium, uye chiyero chechromium uye nickel zvinoda kudzorwa zvakasimba. Imba inonyungudutsa yayo yakasimbiswa bar stock kana kudzoreredza pasi pemhepo inodzorwa yakasiyana neyekutenga zvisina tsarukano ingots pamusika.
Kune chero yakakosha application, iwe unoda yakazara chemistry mishumo uye mechanic test mishumo kubva kune chaiyo kupisa yakawanda. Iyi ndiyo tsika yakajairika yekushanda kwehunyanzvi. Iko kugona kupa iyi nhanho yezvinyorwa chiratidzo chinyararire chekukosha kweiyo foundry. Kana uchiongorora mutengesi senge ataurwa, kushanda kwavo kwenguva refu kunoratidza kuti vakagadzira masisitimu eizvi. Anopfuura makore makumi matatu, unogona kuona kuenderana kwezvinhu zvekutsvaga uye kutonga kwakawanda, kana iwe haugare mubhizinesi uchishandira maindasitiri vatengi.
Uyezve, kune zvikamu zveaerospace, kudzivirira, kana yepamusoro-inoshanda mota, chinodiwa chinowanzo svika pakuongororwa saizi yezviyo, kuongororwa neradiographic kune yakatarwa zviyero (seASTM E192), uye kunyangwe corrosion bvunzo. Kutsanangura 17-4 PH yekudyara kukanda ingori mutsara wekuvhura weakareba tekinoroji yedhizaini inotonga zvese izvi.
Nguva Yokuishandisa, uye Nguva Yokutarira kumwe Kumwe
Saka, mushure mezvose izvi, kupi 17-4 PH yekukandira mari inoita zvine musoro? Yakanyanya kunaka kune zvikamu zvinoda yakakura simba-ku-huremu reshiyo, yakanaka kuneta simba, uye yakanaka corrosion kuramba munzvimbo dzakanyanya kusimba pane izvo zvingada super austenitic kana nickel-based alloy. Funga mashizha eturbine, mapombi epombi, miviri yevharuvhu, zvikamu zvepfuti, uye zvikamu zvekuvhiya. Iyo inozadza niche pakati peyakajairwa 300-yakatevedzana isina tsvina uye inodhura zvakanyanya cobalt-based kana nickel-based alloys.
Asi hakusi kukwidziridzwa kwepasi rose. Kana chikamu chako chiine ngura yakanyanyisa zvinodiwa (semuenzaniso, kugara uchinyudzwa mumvura yemunyu), duplex simbi isina tsvina kana yepamusoro nickel alloy inogona kunge iri nani. Kana iwe uchida kuomarara kwakanyanya pane tembiricha ye cryogenic, tarisa kumwe kunhu. Kana iyo geometry yakaoma zvekuti kupisa kurapwa kunokanganisa kusingagadzirike, unogona kumanikidzwa kushandisa mechanically work-hardened austenitic stainless panzvimbo.
Chinhu chakakosha chekutora kubva kumakore ekubata neizvi ndechekuti 17-4 PH yekudyara kukanda iketani yemaitiro, kwete chinhu. Inoda kuremekedzwa kwekudyidzana pakati pesimbi, yekutanga engineering, sainzi yekurapa kupisa, uye machining chaiwo. Kuigadzirisa kunonzwa sekukunda kudiki nguva dzese. Kuzvikanganisa idzidzo inodhura. Musiyano unowanzo rara mukusarudza vadyidzani vanoona iyo ketani yese, kwete chete yavo yekubatanidza mairi.
