Zopangira zitsulo zosapanga dzimbiri pafakitale ya zida zamagetsi zimafuna zambiri kuposa kukana dzimbiri - zimafunikira kukhazikika kwapang'onopang'ono panjinga yotentha, kukhulupirika kwa microstructural pa 400 ° C +, ndi zero kulolerana kwa porosity m'malo opanikizika kwambiri. Tawonapo nyumba zitatu zolephera za ma valve opangira magetsi akubwerera kuchokera ku fakitale yamagetsi yaku Southeast Asia chifukwa chopezacho chidalumpha kuyesa kwa ultrasonic pachipata chowotcherera. Ichi ndichifukwa chake kutchula zitsulo zosapanga dzimbiri za fakitale ya zida zamagetsi kumatanthauza kugwirizanitsa sayansi ya zinthu, kuwongolera njira, ndi kutsimikizira magwiridwe antchito - osati kungoyika bokosi ngati "CF8M".
Chifukwa chiyani Investment Casting Imamenya Kuponya Mchenga kwa Zida Zamphamvu Zofunikira
Sizinthu zonse zoponyera zitsulo zosapanga dzimbiri zimagwira ntchito mofanana pansi pa kupsinjika kwa cyclic matenthedwe. M'miyezi yathu yapitayi 18 yopanga nyumba zapampu zamakasitomala amafuta & gasi, zida za 316L zoponyera ndalama zidawonetsa 42% ma microcracks ochepa pambuyo pa kukakamiza kwa 5,000 motsutsana ndi magawo ofanana ndi mchenga. Chifukwa chiyani? Kuyika ndalama kumapereka kulolerana kolimba (± 0.3 mm vs ± 1.2 mm), kutsirizika kwapamwamba (Ra 3.2 µm vs Ra 12.5 µm), ndi kufanana kwambewu kwapamwamba-ndikofunikira kwambiri pamene gawo lanu lizimitsa mpope wopatsa chakudya chamutu wapamwamba womwe ukuyenda pa bar 220.
Kuponyera mchenga kumakhalabe kotheka pamaziko akulu, osapsinjika pang'ono-monga zoyambira pampu kapena mafelemu othandizira ma turbine-kumene kulemera ndi mtengo zimachulukira. Koma pamisonkhano yozungulira, matupi a valve, kapena nyumba zomangira nthunzi, kuponya ndalama sikungakambirane. Timatsimikizira gulu lililonse ndi kusanthula kwa spectral, kuyesa kwamphamvu pa ASTM A743, ndikuwunika kwa radiographic ku ASME BPVC Gawo V. Palibe kupatula.
Kusankha Zinthu Sizimangokhudza Nambala Yamagiredi
"316 zosapanga dzimbiri" sizikukuuzani chilichonse chokhudza zochitika zenizeni padziko lapansi. Timafunsa mafunso atatu tisanatchule: Kodi kutentha kwapamwamba kwambiri ndi kotani? Kodi kloridi ilipo-ngakhale pa 5 ppm? Kodi gawoli limakhala ndi kutopa kwamakina kapena kungolemetsa?
- Kwa mavavu a condenser okhazikika m'madzi a m'nyanja: Timatchula F44 (UNS S32750) super duplex-osati 316-chifukwa PREN yake> 40 imakana kuponya kumene ma chloride amakhazikika muming'alu.
- Kwa mapampu a geothermal brine: Chithunzi cha ASTM A995 6A (CD4MCu) imayendetsa H₂S + CO₂ bwino kuposa magiredi awiri owirikiza kawiri chifukwa cha kuwongolera kwa ferrite/austenite.
- Za ntchito za nyukiliya: CF3M castings amakumana ndi yankho lonse annealing + quenching pa ASTM A351, ndiye intergranular dzimbiri kuyezetsa pa ASTM A262 Practice E.
Timakana zinthu zopangira popanda malipoti oyesa mphero owonetsa zinthu zotsatsira makamaka sulfure (<0.015%) ndi mpweya (<0.002%). Kupuma kwa kasitomala kwa miyezi 12 kunabwerera ku sulfure wokwezeka yemwe amachititsa kung'ambika kotentha pomaliza kukonza. Phunziro limenelo linasintha ndondomeko yathu yoyendera - ndi yawo.
Kuphatikizana Kokhazikika Kumathetsa Zowawa Zopanga Zenizeni
Zolephera zambiri sizimachitika pakuponya-koma pamawonekedwe apakati pa kuponyera ndi makina. Thupi la valve loponyera mchenga limatha kudutsa NDT, komabe limazungulira 0.15 mm pa CNC mphero chifukwa cha kupsinjika kotsalira. Timachotsa chiwopsezochi poyang'anira unyolo wonse: kuponyera → chithandizo cha kutentha kwapang'onopang'ono → makina ovuta → kukalamba → kumaliza kukonza → kutsimikizira kwa CMM.
Malo athu ogwirizana ndi ISO amayendetsa izi pansi pa denga limodzi. Timapima chiboliboli chilichonse ndi makina oyezera mpweya omwe amawunikidwa tsiku ndi tsiku; kutsimikizira kukhazikika kwa zibowo za tsinde za ma valve pogwiritsa ntchito zofananira zowonera; ndi kuuma kwa mapu pamwamba pazigawo zotenthedwa ndi zoyesa za Rockwell. Pamene kasitomala wa ku Ulaya ankafuna nyumba 48 zofananira za turbine zoperekedwa m'milungu 11, tinapanga mapatani, kuthira, kuyika makina, ndi kuyesa-zonse m'nyumba. Palibe ma handoffs. Palibe kulumikizana molakwika. Palibe ndandanda zotsalira.
Izi sizothandiza - ndi physics. Kupanga makina oponya popanda kudziwa momwe amagawira kupsinjika kuli ngati kukonza injini yotseka m'maso.
Zomwe Mumafunikira Musanayambe Kuyitanitsa Choyamba
Musatitumizire fayilo ya CAD ndikuyembekeza mtengo. Bweretsani zinthu zinayi izi kuunikanso kwaukadaulo:
- Chojambula chojambulidwa chowunikira ma callout a GD&T omwe akukhudza ntchito, osati kukongola kokha.
- Deta ya malo ogwirira ntchito: kutentha kwapamwamba kwambiri/mphindi, chemistry yamadzimadzi (yokhala ndi pH, kloridi, milingo ya H₂S), ndi kayendedwe kantchito (yopitilira vs intermittent).
- Zofunikira pakuyesa: kuthamanga kwa hydrotest, njira ya NDT (RT/UT/PT), ndi njira zovomerezera (mwachitsanzo, "palibe zizindikiro> 1.5 mm kutalika").
- Zofunikira pakutsata: Kodi mumafunikira kufufuza kwathunthu kwa chiwerengero cha kutentha? Ziphaso zakuthupi pa EN 10204 3.1 kapena 3.2?
Tiyankha mkati mwa maola 48 ndi mayankho opangira - kuphatikiza malingaliro monga kusamutsa gawo lakhoma lopyapyala kuti tipewe kuchepa kapena kuwonjezera ngodya kuti tichepetse mphamvu yotulutsa nkhungu. Umu ndi momwe zopangira zitsulo zosapanga dzimbiri za fakitale ya zida zamagetsi zimasunthika kuchoka pamalingaliro kupita ku ntchito yodalirika.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga mbali zomwe zimakhalapo - osati kungokumana ndi zina. Cholinga chathu chimakhalabe chocheperako: kuponyedwa mwatsatanetsatane kwa ma hydraulic system, zida zamafuta & gasi, ndi makina apampu opangidwa ndi injiniya pomwe kulephera sikungatheke. Sitithamangitsa volume. Timathetsa mavuto a dimensional, metallurgical, ndi magwiridwe antchito-kuyambira ndi kutsanulira koyamba.
