Pamene mainjiniya afotokoza Icoloy800 chifukwa cha kutentha kwambiri, ntchito zowononga kwambiri-monga machubu osintha nthunzi, zipolopolo zowotcha kutentha, kapena ma hydrocarbon processing manifolds-samangosankha aloyi. Akubetcherana pa kusinthasintha kwazitsulo, kukhulupirika kwapang'onopang'ono pansi pa njinga yamoto yotentha, komanso kulekerera kusagwirizana kwapang'onopang'ono. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni Inoloy800 fakitale nkhani—osati wotsatsa malonda, osati malo opangira zinthu zonse, koma malo okhala ndi zolembedwa zowongolera zowongolera njira, kukhazikika kwakukula kwambewu, ndi magawo ogwirira ntchito otentha okhudza Fe-Ni–Cr superalloys.
Tawona ma projekiti ambiri akuyimitsidwa chifukwa wogulitsa adatchula Incoloy800-koma adapereka zinthu zokhala ndi 0.02% ya sulfure wochulukirapo, zomwe zimayambitsa kusweka kwa intergranular panthawi yotchinga. Kapena choyipirapo: magawo opangidwa kuchokera ku billet ndi mbiri ya kutentha kosatsimikizika, zomwe zimatsogolera kuphulika msanga mu ntchito ya 750 ° C. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., dongosolo lililonse la Incoloy800 limayamba ndi malipoti oyesa mphero otsimikiziridwa ndi ASTM B407 ndi ASME SB-407. Timangochokera ku mphero zotsimikizika kupita ku NADCAP AC7108 pokonza nickel-alloy-ndipo timakhalabe ndi traceability: nambala yochuluka, ID yosungunuka, chipika chamankhwala a thermomechanical, ndi kutsimikizira kuuma kwa pambuyo pa anneal. Palibe kuchotserapo.
Zomwe zimasiyanitsa wokhoza Inoloy800 fakitale kuchokera kwa wogulitsa katundu sikungotsimikizira-ndimo momwe alloy amachitira * pambuyo * kupanga. Incoloy800 imagwira ntchito mwachangu. Matenthedwe ake matenthedwe ndi otsika. Mphamvu zake zotentha zimafuna njira zoyendetsera bwino za zida komanso kuwongolera koziziritsa kukhosi. Timayendetsa mapulogalamu onse a Incoloy800 CNC pamakina a 5-axis okhala ndi nthawi yeniyeni yowunikira katundu wa spindle. Mitengo ya chakudya imasintha kutengera kulimba kwa mapu - chifukwa batchi imodzi imatha kusiyanasiyana ± 15 HB kudutsa gawo lonselo. Sitimangosindikiza makina; timapanga makina kuti *agwire ntchito*. Pampu yanyumba si yozungulira yokha-iyenera kusunga ≤0.015 mm pa kutentha kwa ntchito, kuti chisindikizo cha piston sichimayankhula. Izi zimafuna kuti muchepetse kupsinjika * musanayambe * kukonza komaliza, osati pambuyo.
- Dimensional bata pansi pa katundu wotentha: Zigawo zonse za Inkoloy800 zimapeza mpumulo wa kupsinjika kawiri-choyamba pa 900 ° C kwa maola a 2 mu ng'anjo yotsuka nayitrogeni, kenako pa 760 ° C kwa maola 4 ndikuzizira pang'onopang'ono (≤20 ° C / ola)
- Kukhulupirika kwapamtunda kwa kukana dzimbiri: Palibe mphesa akupera. Palibe ma microcracks apansi panthaka. Chigawo chilichonse chimadutsa kuyan'anila kolowera kwa fulorosenti (ASTM E1417) ndikutsimikizira kuuma kwa pamwamba (Ra ≤ 0.8 µm pankhope zosindikizidwa)
- Kukonzekera kwa weld: Zopangira zonse zimathiridwa yankho ndikuzifutsa pa ASTM A959, zomwe zili ndi ferrite zotsimikizika pansipa 0.5% - ndizofunika kwambiri kupewa kutsekeka kwa sigma-phase mu ma welds ambiri
Ena angatsutse kuti kuponyera Incoloy800 sikungatheke-kumakonda kwambiri kuchepa kwa porosity, kovuta kwambiri kudyetsa. Koma mzere wathu woponyera mchenga umakhala ndi machitidwe opangira ma gating omwe amapangidwira ma aloyi a Fe-Ni-Cr: matabwa okhala ndi ceramic, omwe amatenthedwa mpaka 350 ° C, ndikukhazikika kokhazikika komwe kumayendetsedwa ndi kuzizira komanso kuyika kokwera komwe kumatsimikiziridwa ndi MAGMAsoft simulation. Timaponyera ma valve a Incoloy800 mpaka 120 kg-osati ngati ma prototypes, koma monga zigawo zopanga zoyenerera ku API 6A PR2. Mfungulo yake? Kuwongolera liwiro lolimba mpaka ± 0.3 mm / s kudutsa gawolo. Izo sizongopeka. Ndi ndondomeko yoyendetsedwa ndi physics.
Funso lathu lamakasitomala lomwe nthawi zambiri si "Kodi mungathe?" -ndi "Kodi ndingapewe bwanji msampha womwe udapha gulu lathu lomaliza?" Chifukwa chake tidaphatikizira kuunikanso kwauinjiniya koyambirira: kutsimikizika kwa GD&T motsutsana ndi cholinga chogwira ntchito (osati kungotengera kutsata), mafanizidwe okulitsa matenthedwe a mating a flange, komanso malingaliro a bolt-torque kutengera mphamvu yokolola yeniyeni ya kutentha komwe kwaperekedwa. Kotala lapitalo, tidayika chizindikiro chomwe makulidwe akhoma omwe adanenedwawo angadutse chiwopsezo chozizira kwambiri cha mpweya wa carbide-tikuwonetsa kusintha kwa geometry m'malo mwamankhwala okwera mtengo a pambuyo pa weld. Izi zidapulumutsa milungu itatu ndi $ 18,000 pakukonzanso.
Ngati mukufuna zida za Incoloy800 zomwe zimapulumuka maola 30,000 pa 800 ° C popanda makulitsidwe, kutsika, kapena kupotoza - ndiye kuti mufunika zambiri kuposa kutsata zakuthupi. Mukufunikira mnzanu yemwe amachitira chemistry ya alloy monga poyambira, osati mzere womaliza. Ndani amamvetsetsa kuti ma nozzles a AMS 5387 cobalt ndi nyumba zapampopi za Incoloy800 zimagawana njira yofananira: kuwongolera ma microstructure kudzera munjira iliyonse. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito tsiku ndi tsiku - osati monga chiphunzitso, koma monga machitidwe ovomerezeka. Kwa magwiridwe antchito ofunikira, palibe choloweza m'malo mwazochitikira zomwe zidapangidwa m'njira zolephera zenizeni. Ndicho chimene chimatanthawuza chowona Inoloy800 fakitale.
