China OEM makonda ductile chitsulo castings mankhwala ndimchenga nkhungu kuponyera ndondomekondiCNC makina.
Ductile cast iron, yomwe imayimira gulu lachitsulo choponyedwa, chomwe chimatchedwanso nodular iron, spheroidal graphite cast iron kapena SG iron. Nodular kuponyedwa chitsulo amapeza nodular graphite kudzera spheroidization ndi inoculation mankhwala, amene bwino bwino makina katundu wa chitsulo chotayidwa, makamaka plasticity ndi kulimba, kuti apeze mphamvu apamwamba kuposa mpweya zitsulo.
Chitsulo chachitsulo sichinthu chimodzi koma ndi gawo la gulu la zipangizo zomwe zingathe kupangidwa kuti zikhale ndi katundu wambiri pogwiritsa ntchito microstructure. Chikhalidwe chodziwika bwino cha gulu ili la zipangizo ndi mawonekedwe a graphite. Muzitsulo za ductile, graphite imakhala ngati tinthu tating'onoting'ono osati ma flakes monga momwe ili muchitsulo chotuwa. Mawonekedwe akuthwa a ma flakes a graphite amapangitsa kuti pakhale kupanikizika mkati mwazitsulo zachitsulo komanso mawonekedwe ozungulira a tinthu tating'onoting'ono tochepa, motero amalepheretsa kupanga ming'alu ndikupereka ductility yowonjezera yomwe imapatsa aloyi dzina lake.
Nodular cast iron yakula mwachangu kukhala chitsulo choponyedwa chachiwiri ku chitsulo chotuwira ndipo chimagwiritsidwa ntchito kwambiri. Zomwe zimatchedwa "chitsulo cholowa m'malo mwachitsulo" makamaka zimatanthawuza chitsulo cha ductile. Chitsulo chachitsulo nthawi zambiri chimagwiritsidwa ntchito popanga zida za crankshafts ndi camshafts zamagalimoto, mathirakitala, ndi injini zoyatsira mkati, komanso ma valve opanikizika apakati pamakina ambiri.
Pamapangidwe azinthu zopangira chitsulo cha ductile, gulu lapadera la projekiti liyenera kukhazikitsidwa kuti lichite "Kulephera Kupanga Njira ndi Kusanthula Zotsatira" (DFMEA). Gulu la polojekitiyi nthawi zambiri limakhala ndi opanga zinthu, opanga makina opangira zinthu, komanso akatswiri oteteza zachilengedwe. Zomwe zili mu kusanthula kwa DFMEA ziyenera kuphatikizapo ngati zofunikira za khalidwe la kuponyedwa kwa gawolo, ndondomeko yoponyera kamangidwe kake, ndi ndondomeko yoponyera zofunikira zotetezera chilengedwe zonse zakwaniritsidwa.
Kachitidwe ka Ductile Iron Castings:
• Kuchuluka kwa madzi ndi kuchepa kwa mizere kwa chitsulo cha ductile ndizofanana kwambiri ndi chitsulo chotuwira
• Chizoloŵezi cha kuchepa kwa voliyumu ndi kupsinjika maganizo kwamkati ndi kwakukulu kuposa chitsulo chachitsulo chotuwa, chomwe chimakonda kuchepa ndi kusweka.
• Mphamvu, pulasitiki, ndi zotanuka modulus za ductile iron ndizokulirapo kuposa zachitsulo chotuwa, zolimba kuti zipse.
• Mayamwidwe owopsa ndi oyipa kuposa chitsulo chotuwira
Mawonekedwe a Ductile Iron Castings:
• Nthawi zambiri amapangidwa kukhala yunifolomu khoma makulidwe, ndipo yesani wandiweyani gawo ayenera kupewa ngati n'kotheka
• Pazigawo zina zochindikala ndi zazikulu, payenera kukhazikitsidwa kabowo kapena kamangidwe ka nthiti zolimba
Ubwino Wakuponya Mchenga:
• Mtengo Wotsika chifukwa cha nkhungu zotsika mtengo komanso zobwezeretsedwanso komanso zida zosavuta kupanga.
Kulemera kwa mayunitsi osiyanasiyana kuchokera ku 0.10 kg mpaka 500 kgs kapena kupitilira apo.
• Mapangidwe Osiyanasiyana kuchokera ku mtundu wosavuta kupita ku mtundu wovuta.
• Oyenera kupanga zofunika zosiyanasiyana kuchuluka.
