Kovar alloy 4j29

4J29 alloy amadziwikanso kuti Kovar alloy.Aloyi ili ndi mzere wowonjezera wofanana ndi galasi lolimba la borosilicate pa 20 ~ 450 ℃, malo apamwamba a Curie komanso kukhazikika kwa kutentha kwa microstructure.Filimu ya oxide ya alloy ndi wandiweyani ndipo imatha kulowetsedwa bwino ndi galasi.Ndipo sichimalumikizana ndi mercury, yoyenera kugwiritsidwa ntchito mu chida chomwe chili ndi kutulutsa kwa mercury.Ndilo chosindikizira chachikulu cha chipangizo cha vacuum chamagetsi.Amagwiritsidwa ntchito popanga Fe-Ni-Co alloy strip, bar, mbale ndi chitoliro chokhala ndi galasi lolimba / ceramic lofananira kusindikiza, lomwe limagwiritsidwa ntchito kwambiri mumagetsi a vacuum, zamagetsi zamagetsi ndi mafakitale ena.
4J29 Chidule cha ntchito ndi zofunikira zapadera
Aloyi ndi aloyi wamba wa Fe-Ni-Co wosindikiza magalasi olimba omwe amagwiritsidwa ntchito padziko lonse lapansi.Yakhala ikugwiritsidwa ntchito ndi fakitale yoyendetsa ndege kwa nthawi yaitali ndipo ntchito yake ndi yokhazikika.Amagwiritsidwa ntchito kwambiri posindikiza magalasi amagetsi amagetsi monga emission chubu, chubu la oscillation, chubu choyatsira, magnetron, transistor, pulagi yosindikiza, relay, mzere wotsogolera wozungulira, chassis, chipolopolo, bulaketi, etc. Coefficient yowonjezera ya galasi yosankhidwa ndi alloy iyenera kufanana.Kukhazikika kwa minofu yotsika kumayesedwa mosamalitsa malinga ndi kutentha kwa ntchito.Chithandizo choyenera cha kutentha chiyenera kuchitidwa pokonza kuti zitsimikizire kuti zinthuzo zili ndi zojambula zabwino zozama.Mukamagwiritsa ntchito zida zopangira, kulimba kwake kwa mpweya kuyenera kuyang'aniridwa mosamalitsa.
Covar alloy chifukwa cha zomwe zili ndi cobalt, mankhwalawa ndi osamva kuvala.
Itha kusindikizidwa mosavuta ndi galasi la gulu la molybdenum, ndipo mbali zonse za workpiece zimafuna plating ya golide.
4J29 Formability:
Aloyiyo imakhala ndi ntchito yabwino yozizira komanso yotentha, ndipo imatha kupangidwa kukhala magawo osiyanasiyana ovuta.Komabe, kutentha mumlengalenga wokhala ndi sulfure kuyenera kupewedwa.Pakuzizira kozizira, kuzizira kwa mzerewo kukakhala kokulirapo kuposa 70%, anisotropy ya pulasitiki imapangitsidwa pambuyo poyamwa.Kuzizira kukakhala pamlingo wa 10% ~ 15%, njereyo imakula mwachangu ikatha, ndipo ansotropy ya pulasitiki ya alloy imapangidwanso.Pulasitiki anisotropy ndi yochepa pamene kupsyinjika komaliza ndi 60% ~ 65% ndipo kukula kwa tirigu ndi 7 ~ 8.5.
4J29 Welding katundu:
Aloyi akhoza welded ndi mkuwa, zitsulo, faifi tambala ndi zitsulo zina ndi brazing, maphatikizidwe kuwotcherera, kukana kuwotcherera, etc. Pamene zirconium zili mu aloyi ndi wamkulu kuposa 0,06%, izo zimakhudza kuwotcherera khalidwe la mbale ndipo ngakhale kupanga kuphulika kwa weld.Aloyiyo isanayambe kusindikizidwa ndi galasi, iyenera kutsukidwa, ndikutsatiridwa ndi kutentha kwakukulu konyowa mankhwala a hydrogen ndi pre-oxidation mankhwala.
4J29 Njira yochizira pamwamba: Kuchiza pamwamba kumatha kukhala sandblasting, kupukuta, pickling.
Zigawozo zitasindikizidwa ndi galasi, filimu ya oxide yomwe imapangidwa panthawi yosindikiza iyenera kuchotsedwa kuti ikhale yosavuta kuwotcherera.Zigawozo zikhoza kutenthedwa mpaka 70 ℃ mu njira yamadzimadzi ya 10% hydrochloric acid + 10% nitric acid, ndi kuzifutsa kwa 2 ~ 5min.
Aloyi ali ndi ntchito zabwino electroplating, ndipo pamwamba akhoza kukhala golide, siliva, faifi tambala, chromium ndi zitsulo zina.Pofuna kuwongolera kuwotcherera kapena kukanikiza kotentha pakati pa magawo, nthawi zambiri kumakutidwa ndi mkuwa, nickel, golide ndi malata.Kuti apititse patsogolo madulidwe apamwamba pafupipafupi komanso kuchepetsa kukana kukhudzana kuti muwonetsetse kuti mawonekedwe amtundu wa cathode, golide ndi siliva nthawi zambiri zimakutidwa.Pofuna kukonza kukana kwa dzimbiri kwa chipangizocho, faifi tambala kapena golide zimatha kukutidwa.
4J29 Kudula ndikupera ntchito:
Makhalidwe odula a alloy ndi ofanana ndi austenitic zitsulo zosapanga dzimbiri.Kukonza pogwiritsa ntchito chitsulo chothamanga kwambiri kapena chida cha carbide, kudula kwachangu.Kuzizira kungagwiritsidwe ntchito podula.Alloy ali ndi ntchito yabwino yogaya.
4J29 Zofunikira zazikulu:
4J29 chitoliro chosasunthika, 4J29 chitsulo mbale, 4J29 zitsulo zozungulira, 4J29 forgings, 4J29 flange, 4J29 mphete, 4J29 welded chitoliro, 4J29 zitsulo gulu, 4J29 bar molunjika, 4J29 waya ndi mafananidwe kuwotcherera zinthu, 9 × 29 chitsulo chozungulira, 9 × J29 bar, 4J29 kukula mutu, 4J29 chigongono, 4J29 tee, 4J29 4J29 mbali, 4J29 mabawuti ndi mtedza, 4J29 zomangira, etc.
