Pamene mainjiniya afotokoza fakitale yopanga zitsulo zopangira chitsulo mayankho, sikuti amangogula magawo-akuteteza kukhazikika kwapang'onopang'ono pakuyenda kwapang'onopang'ono, kusasinthika kwapang'onopang'ono pamagulu 500 a mayunitsi, komanso kulolerana ziro kwa porosity m'matupi othamanga kwambiri. Tawona ma projekiti ambiri akuchedwa ndi ogulitsa omwe amawona kuponya ndalama ngati njira imodzi-makamaka ndi imvi ndi ductile cast irons, komwe kuwongolera kofanana ndi mpweya, mitengo yamitengo ya nkhungu, komanso kasamalidwe ka mame pomanga zipolopolo zimatsogolera mwachindunji machinability ndi moyo wotopa.
Chifukwa Chake Cast Iron Imafuna Zambiri Kuposa Kungopeza Malo
Chitsulo chachitsulo sicho "chosavuta kuponya" chifukwa chimayenda bwino. Maonekedwe ake a graphite - flakes mu iron imvi, tinthu tating'onoting'ono mu ductile - amayankha kwambiri kuzizira, nthawi yothira, komanso chinyezi chozungulira panthawi yosonkhanitsa sera. Pamalo athu ogwirizana ndi ISO ku Qingdao, timachita chilichonse ngati kuyesa kwazitsulo: ziphaso zakuthupi zomwe zimatsimikiziridwa musanalowetse, ng'anjo imasungunuka ndikutsata mawonekedwe a nthawi yeniyeni, ndi nkhungu za zipolopolo zophikidwa pa 1,100 ° C ndi nthawi yokhala ndi mphindi 30-osati chifukwa muyezo umanena choncho, koma chifukwa timachepetsa kuchepetsedwa kwa micro2% 1,050°C kwa>25 mphindi.
Tapereka ma valve opitilira 470 opangira ma hydraulic system omwe amagwira ntchito pa bar 420 - palibe yomwe idalephera. Chifukwa chiyani? Chifukwa sitimayima pa ASTM A536 kapena GB/T 1348. Timatsimikizira nodularity pogwiritsa ntchito kusanthula kwazithunzi pagawo lachitatu lililonse, timayendetsa mipiringidzo yokhazikika kuchokera pakuthira komweko monga gawo lopangira, ndi mapu kuuma ma gradients kudutsa makoma a silinda nyumba pogwiritsa ntchito 12-point Rockwell C scans. Umu ndi momwe mumagwirira malo ozizirira bwino omwe amasintha khoma la 30-mm kukhala mawonekedwe osalimba.
Kumene Kutaya Ndalama Kumamenya Mchenga-ndipo Pamene Sichitero
Kuponyera ndalama kumapereka ± 0.05 mm kulolerana kwa mzere ndi Ra 1.6 µm ngati-cast pamwamba - yofunikira panyumba za silinda za pampu ya piston pomwe geometry yosindikizira imawonetsa kutayikira. Koma timauza makasitomala patsogolo: ngati gawo lanu likulemera kuposa 45 kg kapena lili ndi ndime zamkati zokulirapo kuposa 8 mm, kuponyera mchenga nthawi zambiri kumapereka kukhazikika kwapakati komanso mtengo wotsika pa kilogalamu. Tachoka ku mawu omwe mchenga umapereka kukhazikika kwa khoma - chifukwa kuwona mtima kumalepheretsa kulephera kwamunda.
Mayendedwe athu a haibridi amawongolera kusiyana. Mwachitsanzo: zodzigudubuza za winch center shaft zimayamba ngati chitsulo choponyera chitsulo (ASTM A), kenako ndikuyatsa CNC kuyatsa 5-axis lathes kupita ku magazini enieni okhala mkati mwa 0.015 mm TIR. Kuchiza kutentha kumatsatira-kuzimitsa pa 890 ° C, kutentha pa 620 ° C-kenako kuwombera peening kuti apangitse + 280 MPa pamwamba compressive stress. Chotsatira? Moyo wa shaft unatalikitsidwa 3.7 × pamagalimoto opangira uinjiniya wakunyanja komwe grit yokhala ndi mchere imafulumizitsa kuponyera.
Zinayi Zosakambirana mu High-Performance Cast Iron Production
Aliyense fakitale yopanga zitsulo zopangira chitsulo Kudzinenera kudalirika kuyenera kuwonetsa zowongolera zinayi izi:
- Kufufuza kwazinthu mpaka kutentha nambala-osati ma certs a mphero, koma malipoti obwerezabwereza a Si, Mn, P, S, ndi Cu/Ni/Cr otsalira mugulu lililonse;
- Kutsimikizira kukhulupirika kwa zipolopolo-Timagwiritsa ntchito kuyesa kwa helium pakutulutsa kofunikira, osati kungoyang'ana;
- Mu-ntchito yoyang'anira zipata-CMM imayang'ana pambuyo pochotsa phula, itatha kuwombera, ndikuwombera pambuyo-kuphulika-makina asanayambe;
- Kutsimikizika kogwira ntchito pazoyeserera zoyeserera- matupi a valve othamanga-oyesedwa pa 1.5 × ovotera kuthamanga; mpope nyumba zozungulira molingana ndi giredi ya G2.5.
Timakana 8.3% ya zolemba zoyambirira - osati chifukwa cha zolakwika zodzikongoletsera, koma chifukwa ma callouts a GD&T pamawonekedwe a flange adapitilira kulolerana kwa 0.03 mm. Chilango chimenecho chimapitilira mpaka pamlingo wapakatikati: dongosolo lathu lowonda limagawa nthawi yosinthira zipolopolo zowuma pamene chinyontho cha monsoon chikukwera pamwamba pa 75% RH. Chifukwa kuponya sikukhudzana ndi nyengo yabwino - ndizokhudza kuwongolera zomwe mungayesere.
Zimene Amayinjiniya Amafunikira—Osati Zimene Timabuku Amalonjeza
Mufunika kumveka bwino pakusinthana kwanthawi yotsogolera: kuyika ndalama kumawonjezera masabata 2-3 kuti mupange zida ndi kupanga zipolopolo, koma kumachotsa makina achiwiri pa 68% yazinthu pamapangidwe athu apampu. Mufunika kuwonekera poyang'anizana ndi cobalt-aloyi - timaponyera nthawi zonse AMS 5387 pambali pa chitsulo cha ductile pamageti ogawana, koma pokhapokha titatsimikizira kusagwirizana kwa kukulitsa kwamafuta pogwiritsa ntchito kayeseleledwe komaliza kakutsogolo kolimba. Mukufuna wina amene adzayimitse mikangano ya GD&T msanga: tidagwira kulolerana kwa 0.02 mm pa dzenje la 12-mm lomwe limafuna kusamutsa dongosolo lonse la data-kupulumutsa $24k m'mipando yopanda kanthu.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. samagulitsa castings. Timathetsa njira zolephereka - njira zotayikira, kupotoza kwa kutentha, kuvala kwa abrasive-pogwirizanitsa zitsulo, ndondomeko ya fizikiki, ndi zolinga zamakina. Mphamvu zathu zagona pakuchita zinthu zochepa, koma kuzichita ndi kubwereza zolembedwa: kuchokera ku T800 cobalt nozzles yonyamula 650 ° C yosungunula mpaka pazipampu zachitsulo zomwe zidapulumuka zaka 15 zakunyanja popanda kuwonongeka.
Ngati polojekiti yanu yotsatira ikufuna fakitale yopanga zitsulo zopangira chitsulo Kuthekera kokhazikika pakuyezera-osati kutsatsa-kuyamba ndi kujambula. Tikuwuzani zomwe zimatha kupanga, zomwe zikufunika kukonzanso, komanso komwe kuli pachiwopsezo. Osati m'mawu osadziwika bwino. Mu ma microns, megapascals, ndi manambala a kutentha kwakuthupi.
