Mukuwona zofananira ngati N08028 zikubwera pa desiki, ndipo chibadwa choyamba m'masitolo ambiri ndikuchichita ngati china chilichonse chosapanga dzimbiri cha austenitic. Ndipamene vuto limayambira. Si bwino 316L. Ndi chilombo chosiyana kwathunthu, chomangidwira malo owopsa a chloride, ndipo ngati simulemekeza zovuta zake - makamaka panthawi yopangira makina ndi kuponyera - mukudzipangira ntchito yokwera mtengo kapena, choyipa, kulephera kwamunda. Ine ndaziwona izo zikuchitika. Izi ndizochepa tanthauzo labukhu komanso mndandanda wazowonera kuchokera pakupanga magawo nawo.
Aloyi Yekha: Kuposa Manambala Okha
Papepala, N08028 (kapena Aloyi 28, ngati mukufuna dzina lodziwika bwino) ndi faifi tambala, high-chromium, low carbon stainless ndi molybdenum yofunika kwambiri ndi zowonjezera zamkuwa. Mkuwa ndiye chinsinsi - ndizomwe zimakankhira kukana kwa dzimbiri mu ntchito za sulfuric ndi phosphoric acid kuposa zomwe 904L imapereka. Koma pepalalo silikuwuzani za zingwe, tchipisi tolimba chomwe chimatulutsa potembenuka, kapena momwe kutsika kwake kumatanthawuza kuti kutentha kumangofika kumapeto kwenikweni. Simungathe kuyendetsa zida mwachangu ngati 316, ndipo kusankha kozizira kumakhala kofunikira. Sitolo yomwe yakhalapo, ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zawo makumi atatu akujambula ndi kupanga makina, zikanakulitsa chidziwitso chodabwitsachi. Mumaphunzira kumvera makina, penyani mtundu wa chip.
Vuto limodzi lodziwika bwino ndikulingalira kuti kuwotcherera kwake ndikosavuta. Sizowopsa, koma zimafuna mpweya woteteza kwambiri komanso kuwongolera kutentha kwapakati kuti mupewe kusweka kotentha. Nthawi ina tinali ndi matupi akuluakulu a valve, oponyedwa kudzera mwawo chipolopolo nkhungu kuponyera ndondomeko, kuti anapanga microfissures zabwino mu HAZ pambuyo kuwotcherera. Chifukwa chake? Mawonekedwe a chinyezi mumzere wa argon. Kanthu kakang'ono, zotsatira zowononga. Zinakakamiza kuwunikiranso mzere uliwonse wa gasi ndi silinda yowotcherera.
Kumene aloyiyi imawaladi ndi malo omwe angadye zitsulo zina zosapanga dzimbiri zamoyo. Ganizirani za flue gas desulfurization scrubber internals, kapena mapaipi a m'mphepete mwa nyanja kumene ma chlorides ndi CO2 onse alipo. Ndi njira yothetsera vuto linalake, loyipa. Simukuzifotokoza chifukwa ndizofunika kwambiri, mumazitchula chifukwa palibe chomwe chingakhalepo.
Zovuta Zoponya: Kuyambira Chitsulo Chosungunula mpaka Kutulutsa Phokoso
Kuyika ndalama nthawi zambiri kumakhala kovutirapo N08028 zida zapadera zachitsulo zosapanga dzimbiri, makamaka amene ali ndi ndime zocholoŵana za mkati. Kulondola kwa dimensional ndikofunikira. Koma N08028 ili ndi kuchuluka kwamafuta owonjezera komanso chizolowezi chocheperako. Mapangidwe a khomo ndi okwera ayenera kukhala owonekera kuti adyetse kuponya bwino ndikupewa porosity yapakati. Ndi luso lothandizidwa ndi pulogalamu yoyeserera masiku ano, koma zokumana nazo sizingalowe m'malo. A foundry's pattern library ndi mbiri yakale yofananira ndi ma geometries ndizofunika kulemera kwake mugolide.
Kuponyera nkhungu ya Shell, njira ina yomwe yatchulidwa ndi QSY, ikhoza kukhala yabwino kwambiri pazigawo zocheperako koma zovuta kwambiri. Chinsinsi apa ndi nkhungu ndi kuyanjana kwachitsulo ndi nkhungu. Ndi nickel ya N08028 yapamwamba, sulfure iliyonse mumchenga wa nkhungu imatha kung'ambika koopsa. Mufunika mchenga waukhondo, womangidwa ndi mankhwala. Ndi tsatanetsatane yomwe imalekanitsa sitolo yomwe imatha kutsanulira kuchokera ku imodzi yomwe ingathe kutulutsa phokoso lodalirika, lokonzekera makina.
Chithandizo cha kutentha sikungakambirane: njira yothetsera vutoli imatsatiridwa ndi kuzimitsa mwamsanga. Cholinga chake ndikubwezeretsa ma alloying amtundu wa chromium, molybdenum, mkuwa kuti akhale olimba ndikusunga momwemo. Kuziziritsa pang'onopang'ono kapena, kumwamba sikuletsa, kuziziritsa kwa mpweya kuchokera ku kutentha kwapakati kumatha kubweretsa magawo achiwiri m'malire a tirigu, kuwonongeratu kukana kwa dzimbiri komwe munalipira. Ndawonapo magawo akulephera kuyesa kosavuta kwa ferric chloride chifukwa wina akuganiza kuti atha kulumpha kuzimitsa madzi pagawo lakuda kuti achepetse kupsinjika. Anachepetsa moyo wautumiki wa gawolo kukhala miyezi mmalo mwa zaka.
Machining: Kumene Chiphunzitso Chimakumana ndi Toolbit
Apa ndi pomwe mphira umakumana ndi msewu. Monga tafotokozera, N08028 imagwira ntchito molimbika kwambiri. Zakudya zanu ndi liwiro lanu liyenera kukhala lolimba kwambiri kuti mulowe pansi pa gawo lolimba la ntchitoyo kuchokera pamadulidwe am'mbuyomu. Kupanga kopepuka, kwamanyazi ndi chinthu choyipa kwambiri chomwe mungachite - kumangomenya pamwamba ndikuwotcha zida. Positive rake geometry, zida zakuthwa, ndi kukhazikika kolimba ndizofunikira. Tidalinganiza magiredi enaake a carbide okhala ndi ma chipbreaker olimbitsa kuti apangitse roughing ndi kumaliza.
Kuziziritsa sikungoziziritsa; ndi zokometsera pa mawonekedwe odulira ndi kuthamangitsa tchipisi tazingwe tisanayambe kuziwotcherera ku workpiece kapena chida. Kuphatikizika kwakukulu, kudzera pazida zoziziritsa kuzizira kunakhala chofunikira pa malo athu opangira makina a CNC omwe amagwiritsa ntchito izi. A shopu CNC makina kuthekera sikungokhudza mtundu wa makinawo; ndi za machitidwe othandizira awa ndi ma database omwe apanga pa ntchito.
Kujambula ndi kugogoda ndi ntchito zovuta kwambiri. Kulimba kwazinthu zimakonda kugwira ndi ndulu. Kwa ulusi wovuta, nthawi zambiri tinkasunthira ku mphero m'malo mogogoda, zomwe zimapereka kuwongolera bwino ndikuphwanya tchipisi bwino. Pamabowo, matepi a spiral-flute okhala ndi kupanikizika kwambiri (EP) mu choziziritsa ndi chinthu chokhacho chomwe chinkagwira ntchito mosadukiza popanda kutsitsa chitoliro kapena kuchigwira mu dzenje.
Kutsimikizira Kwabwino: Si Mfuti ya PMI Yokha
Positive Material Identification (PMI) ndiye osachepera. Mumasanthula billet kapena kuponya ndikutsimikizira kuti zinthu zazikulu zili mgulu. Koma ndicho chiyambi chabe. Pazigawo zofunika kwambiri zautumiki, muyenera kutsimikizira microstructure. Etch yokhazikika iwonetsa ngati mwapeza mawonekedwe amtundu wa austenitic wopanda mafunde owopsa. Njira zotsogola kwambiri monga kuyesa kwa electrochemical potentiokinetic reactivation (EPR) kumatha kuwerengera kuchuluka kwa chidziwitso, chomwe ndi chofunikira pazigawo zomwe zimapangidwira misonkhano yowotcherera.
Kuyesa kosawononga kumakhala kofunikira kwambiri. Kuyezetsa kolowera kwa utoto ndikwabwino pakuwonongeka kwapamtunda, koma pakumveka bwino kwamkati komwe mukuda nkhawa ndi momwe mukupangira, ma radiography (X-ray) nthawi zambiri amatchulidwa. Njira zovomerezera nthawi zambiri zimakhala zokhwima kuposa zitsulo zosapanga dzimbiri. Gulu limodzi la porosity lomwe lingakhale lovomerezeka mu gawo la 304 litha kukhala kukanidwa kwa gawo la N08028 mu ntchito ya chloride, chifukwa ndi malo oyambira poyambira.
Pomaliza, kuyezetsa ntchito. Pazigawo za ma valve kapena zida za pampu, izi zingaphatikizepo kuyesa kwa msonkhano ndi kuyang'ana pakutuluka kwa mipando. Kuchita kwa zinthuzo kumangofunika ngati gawo lomaliza likugwira ntchito yake. Kuwongolera kotsirizaku, kuyambira kusungunuka mpaka kuwunika komaliza, ndizomwe wopereka wokhoza amapereka. Ndi kusiyana pakati pa kugula zitsulo ndi kugula chigawo chogwira ntchito.
Kupeza Zothandiza ndi Kugwirizana
Simumangoyitanitsa magawo a N08028 kuchokera pamndandanda. Ndi njira yogwirizana. Kukambirana koyambirira kwamapangidwe ndikofunikira. Kodi utali wozungulira pang'ono ungakwezedwe pano kuti upewe gawo lopyapyala lomwe ndi lovuta kudyetsa posewera? Kodi mbali yamkatiyi ingathe kupezedwa kudzera mu makina osati kuponya, kuti zisawonongeke? Wogwirizana ndi Integrated kuponya chipolopolo nkhungu, kuponyera ndalama, ndi CNC Machining pansi pa denga limodzi, monga momwe zasonyezedwera https://www.tsingtaocnc.com, ali ndi mwayi pano. The Machining timu akhoza kulankhula ndi gulu foundry pamaso pa chitsanzo ngakhale anapanga, optimizing ndondomeko unyolo.
Prototyping ndi nzeru. Kupanga gawo limodzi kapena kagulu kakang'ono koyamba kutsimikizira njira yopangira, zida, ndi zinthu zomaliza zimatha kupulumutsa ndalama zambiri komanso nthawi pakupanga kwathunthu. Ndi ndalama zochotsera chiwopsezo cha polojekitiyi.
Pamapeto pake, kugwira ntchito ndi ma alloys apadera ngati awa ndi za mgwirizano ndikugawana chidziwitso. Woperekayo akuyenera kumvetsetsa kupsinjika kwa pulogalamu yomaliza kuti alangize zatsatanetsatane monga kumaliza kwapamwamba (kumaliza kopukutidwa kungapangitse kuti zisawonongeke) kapena chithandizo chamankhwala. Wogula akuyenera kumvetsetsa zoperewera za zinthuzo kuti akhazikitse ziyembekezo zenizeni pa mtengo ndi nthawi yotsogolera. Si malonda ogulitsa. Zikachitika bwino, mumapeza gawo lomwe limathetsa vuto lalikulu la uinjiniya. Zikalakwa, mumapeza phunziro lodula kwambiri.
