Pamene wina anena za Hastelloy, ambiri amaganiza za chipolopolo chamatsenga cha dzimbiri. Ziwerengero zama data ndizochititsa chidwi, zedi, koma ndipamene kukambirana kwenikweni kumayambira, osatha. Ndawona mapangidwe ambiri akulephera chifukwa amachitira Hastelloy C-276 kapena C-22 ngati chinthu chosapanga dzimbiri. Si. Kusiyana pakati pa kuthekera kwa aloyi ndi gawo logwira ntchito, lodalirika ndipamene ntchito yeniyeni imachitika-pamalo opangira makina komanso pansi pa malo ogulitsira makina.
Kuthamangitsa Conundrum: Zonse Zili mu Chakudya
Investment casting ndiye kupita ku zovuta Hastelloy alloy mbali, makamaka zooneka ngati zipupa zopyapyala, zocholoŵana zomwe timaziwona nthawi zambiri muzamlengalenga kapena pamilomo yamankhwala. Kuchuluka kwa faifi ya alloy ndi molybdenum kumapangitsa kukana kodziwika bwino, komanso kumapangitsa kuti ikhale chilombo choponyedwa bwino. Mtundu wa solidification ndi wovuta. Mumapeza misozi yotentha ngati khomo lanu ndi njira yokwerera ilibe mawonekedwe. Si chinachake chimene inu mukuchilingalira; ndi zaka za chitsanzo.
Tinaphunzira izi movutikira kale. Gulu la matupi a valve kwa kasitomala, wopangidwira ntchito yowopsa ya chloride. Ma prototypes adadutsa PT, adawoneka bwino. Koma poyesedwa ndi hydro-mayeso, ochepa adapanga kutayikira kwatsitsi pamphambano. Vutolo? Micro-shrinkage. Zosawoneka bwino, osati pamwamba, koma chilema chakupha. Njira yothetsera vutoli sikunali kungogwiritsa ntchito zitsulo zabwinoko. Iwo anali redesigning kudyetsa mitu, kusintha kutsanulira kutentha pamapindikira, ndipo ngakhale lathu la gawo mu nkhungu tsango. Ndilo mbali yosasangalatsa ya ma aloyi apadera.
Sitolo yomwe ikudziwa izi, monga Qingdao Qiangsenyuan Technology (QSY), ali ndi malire. Ndi zaka makumi atatu mu zipolopolo ndi kuponya ndalama, iwo ayenera kuti anathira aloyi wamba wamba ndi wosadziwika bwino wa faifi tambala kunja uko. Kukumbukira kwamabungwe momwe, titi, Hastelloy X amachitira motsutsana ndi Hastelloy B-3 panthawi yozizirira ndi yamtengo wapatali. Simungathe kutsitsa izi kuchokera ku database ya zida.
Machining: Kumene Mabajeti Ogwiritsa Ntchito Zida Amafa
Ngati kuponyera kuli pafupi kunyengerera chitsulo kuti chiwoneke, kukonza ndi nkhondo yolamulidwa. Hastelloy amagwira ntchito molimbika. Mwamakani. Kuyika kosawoneka bwino pang'ono kapena kuchuluka kwabwino kwa chakudya, ndipo mwangopanga malo amderali molimba kuposa chodulira chanu. Simukungodulanso; Mukugaya ndi kutulutsa kutentha kwamisala, zomwe zimawononganso chidacho ndipo zingakhudze zitsulo za gawolo.
Njirayi ndi yochepa komanso yochedwa. Zozizira kwambiri, zokhazikika zokhazikika, ndi ma premium, ma geometries a zida zapadera sizingakambirane. Carbide ndiyokhazikika, koma nthawi zina mumaviika mu ceramic kapena CBN kuti mumalize kupita. Mtengo wa gawo lililonse suli mu chipika cha zinthu; ili mukugwiritsa ntchito zida komanso nthawi yamakina. Ndikukumbukira pulojekiti yosindikizira mphete yayikulu kuchokera ku Hastelloy C-2000. Ntchito yotembenuza inali yowongoka mpaka tidagunda poyambira mkati. Standard grooving oyika anadulidwa mkati mphindi. Tidamaliza kugwiritsa ntchito chida chopangira makonda, ndikuchepetsa chakudya ndi 40%. Zinamveka pang'onopang'ono, koma inali njira yokhayo yomaliza yoyera popanda zigawo zobwerezabwereza.
Apa ndipamene zida zophatikizika zimawonetsa kufunika kwake. Kampani yosamalira zonse zoponya ndi CNC makina m'nyumba, monga QSY yotchulidwa, imatha kukhathamiritsa ntchito yonseyo. Atha kusiya zida zopangira zida zopangira, akudziwa ndendende kuchuluka kwa zinthu zomwe dipatimenti yawo ya CNC imafunikira kuyeretsa khungu ndikukwaniritsa kulolerana. Imathetsa vuto lamasewera pakati pa opanga osiyana ndi ogulitsa makina.
Ma Special mu Special Alloys
Makasitomala nthawi zambiri amabwera ndi pempho la Hastelloy osatchula kalasi. Zili ngati kupempha chitsulo. Kusankha pakati pa B-2 pochepetsa ma acid, C-276 kwa oxidizer osakanikirana, kapena G-30 kwa malo a phosphoric acid ndikofunikira. Ndi chithunzi chofananira ndi mankhwala. Koma pali wosanjikiza wina: fabricability. C-276 ndiye kavalo wantchito pazifukwa zake - ndi yowotcherera kwambiri komanso yokhazikika pamitundu yambiri. B-2 ndi yodziwika bwino kwambiri panthawi yowotcherera ngati siyikugwiridwa bwino.
Ndiye pali kufufuzidwa kwa zopangira zokha. Satifiketi ya Mill ndiyofunika, koma kutsatira ndi mfumu. Pazigawo zofunika kwambiri, muyenera kudziwa kuchuluka kwa kutentha, kusanthula kwamankhwala, komanso kukhala ndi makuponi oyeserera kuchokera kutentha komweko kuti mupeze ziyeneretso. Izi sizongokambirana m'mafakitale monga mafuta akunyanja & gasi kapena mankhwala.
Kutha kupeza ndi kutsimikizira ma alloys apaderawa ndi luso lofunikira. Netiweki ya ogulitsa ndi kukhulupirika wokhala ndi mphero zazikulu ndizofunikira. Pamene kampani ikulemba zitsulo zopangidwa ndi nickel monga mwapadera, zikutanthawuza kuti ali ndi njira yotsimikizira ndi yotsimikizira. Sikuti kukhala ndi mndandanda wazinthu; ndi za kukhala ndi ma tchanelo odalirika.
Pamene Kukwanira Kwabwino Kulibe: The Inspection Gauntlet
Kumaliza gawo ndi chinthu chimodzi. Kutsimikizira kuti ndiyoyenera kugwiritsidwa ntchito ndi zina. Za Hastelloy alloy mbali, macheke owoneka ndi mawonekedwe ndi gawo lotsegulira. Dye penetrant test (PT) ndi muyezo wa zolakwika zapamtunda. Koma pazovuta kwambiri, mukuyang'ana ma radiography (RT) kusaka porosity yamkati kapena kuchepa, ndi kuyesa kwa ultrasonic (UT) kuti mugwirizane ndi kukhulupirika pamisonkhano yowotcherera.
Mayeso enieni, kwenikweni, nthawi zambiri amayesa dzimbiri. ASTM G28 Njira A yowotchera ndi kutentha kwapang'onopang'ono ndiyofala kwa magiredi ambiri a Hastelloy kuti afufuze kukhudzidwa kwa kuwotcherera kapena kutentha kosayenera. Izi sizofulumira. Zimaphatikizapo kuwiritsa chitsanzo mu ferric sulfate-sulfuric acid solution kwa maola 24, kenako kuyeza kulemera kwake. Ndi mayeso owononga, kotero mufunika makuponi a mboni kuchokera pagulu lomwelo. Sitepe iyi imalekanitsa opanga magawo kuchokera kwa ena ogulitsa.
Kuwongolera gauntlet yonseyi kumafuna dongosolo. Ndi zolemba, zolemba za calibration, oyendera ovomerezeka, ndi chikhalidwe chomwe sichimadula mbali. Kampani ina yazaka 30 m'derali yapulumuka chifukwa adapanga dongosololi. Webusaiti yawo ikhoza kungonena kuti makina, koma chinthu chenichenicho ndi phukusi la certification lomwe limabwera ndi gawolo.
The Pragmatic Takeaway
Ndiye, kodi izi zikutanthauza chiyani kwa munthu amene amapeza zigawozi? Choyamba, pitani kupyola kalasi yazinthu. Tchulani malo ogwiritsira ntchito-kutentha, zofalitsa, kuyika, kupanikizika. Chachiwiri, ikani patsogolo kuthekera kwazinthu kuposa mtengo. Kutulutsa kotsika mtengo kwambiri kapena kupanga makina nthawi zambiri ndiko kulakwitsa kokwera mtengo kwambiri. Funsani za zomwe akumana nazo ndi giredi yomwe mwasankha, pemphani kuti muwone zochitika zofananira kapena kukaona malo.
Yang'anani kuphatikiza koyima. Wogulitsa yemwe amawongolera ulendo kuchokera kuzitsulo zosungunuka kupita kumalizidwa, zowunikiridwa, monga zophatikiza kuponya ndalama ndi CNC maluso, mwachibadwa amakhala ndi zochepa zolephera. Ndiwo eni ake tcheni chonse chaubwino. Pomaliza, lemekezani ukatswiri. Mashopu abwino amathetsa mavuto omwe simumadziwa kuti muli nawo. Adzakayikira mwatsatanetsatane chojambula chomwe chimapangitsa kuti pakhale kupsinjika mu alloy iyi, kapena kuwonetsa kusintha pang'ono kwa radius kuti azitha kutulutsa bwino.
Pamapeto pake, wopambana Hastelloy alloy mbali samagulidwa pa alumali. Ndi zotsatira za mgwirizano pakati pa mapangidwe opangidwa mwanzeru ndi kupanga kwanthawi yayitali, pomwe zodziwika bwino za zinthuzo zimamasuliridwa mokhulupilika kukhala chigawo chomwe sichimangokumana ndi zinthu zina, koma chimakhalabe m'dziko lenileni. Ndilo kusiyana pakati pa gawo lomwe linapangidwa ndi Hastelloy ndi lomwe limachitadi monga ilo.
