Kuchita kwa ma forging ndikofunikira pamafakitale osiyanasiyana, kuyambira pamagalimoto mpaka magawo apamlengalenga. Kuphatikizika kwa zinthu zosiyanasiyana za alloy kumatha kukhudza kwambiri zida zopangira, kukulitsa mphamvu, kulimba, komanso kukana zinthu zachilengedwe. Nkhaniyi ikuwonetsa zina mwazinthu zazikulu za alloying komanso momwe zimakhudzira magwiridwe antchito a forgings.
Key Alloying Elements ndi Zotsatira Zake
Mpweya (C):
Mpweya ndi chimodzi mwazinthu zofunika kwambiri za alloying muzitsulo. Zimakhudza mwachindunji kuuma ndi mphamvu zakuthupi. Mpweya wochuluka wa carbon umawonjezera kuuma ndi kulimba kwamphamvu kwa kupanga, kupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kukana kuvala kwambiri, monga zida zodulira ndi zida zamagalimoto. Komabe, mpweya wochuluka ukhoza kupangitsa kuti zinthuzo zisawonongeke, zimachepetsa kukana kwake.
Chromium (Cr):
Chromium imadziwika chifukwa cha kuthekera kwake kolimbikitsa kukana kwa dzimbiri komanso kuuma kwake. Zimapanga chromium oxide pamwamba, zomwe zimateteza kutsekemera kwa okosijeni ndi dzimbiri. Izi zimapangitsa zitsulo zopangidwa ndi chromium kukhala zoyenera kugwiritsidwa ntchito m'malo ovuta, monga mafakitale apanyanja ndi mankhwala. Kuphatikiza apo, chromium imakulitsa kuuma kwa chitsulo, ndikupangitsa kuti ikhale yamphamvu komanso yolimba pambuyo pa chithandizo cha kutentha.
Nickel (Ni):
Nickel amawonjezedwa ku forgings kuti apititse patsogolo kulimba kwawo ndi ductility, makamaka pa kutentha kochepa. Komanso kumawonjezera chuma kukana dzimbiri ndi makutidwe ndi okosijeni. Zitsulo za nickel zimagwiritsidwa ntchito kwambiri m'mafakitale amlengalenga ndi mafuta ndi gasi, komwe kumafunikira mphamvu zambiri komanso kukana malo ovuta. Kukhalapo kwa nickel kumatsitsimutsanso gawo la austenitic, kupanga chitsulo chosapanga maginito ndikuwongolera magwiridwe antchito ake.
Zotsatira Zophatikizana ndi Ntchito Zamakampani
Kuphatikiza kwa zinthu izi ndi zinthu zina zophatikizika, monga molybdenum (Mo), vanadium (V), ndi manganese (Mn), zitha kupanga zida zokhala ndi zida zofananira kuti zigwiritsidwe ntchito mwapadera. Mwachitsanzo, molybdenum imawonjezera kutentha kwamphamvu komanso kukana kwachitsulo, ndikupangitsa kuti ikhale yoyenera masamba a turbine ndi zotengera zopanikizika. Vanadium imayeretsa kamangidwe kambewu, kumapangitsanso mphamvu ndi kulimba kwa kupanga. Manganese amagwira ntchito ngati deoxidizer ndipo amawongolera kuuma komanso kulimba kwazinthuzo.
M'makampani opanga magalimoto, zopanga zokhala ndi mpweya wabwino, chromium, ndi manganese zimagwiritsidwa ntchito kupanga zida zamphamvu kwambiri, zosavala ngati ma crankshafts ndi magiya. M'gawo lazamlengalenga, ma aloyi a nickel ndi titaniyamu ndizofunikira popanga zida zopepuka koma zolimba zomwe zimatha kupirira kutentha kwambiri komanso kupsinjika.
Mapeto
Kuchita kwa forgings kumakhudzidwa kwambiri ndi kuwonjezera kwa ma alloying, chilichonse chimathandizira kuti zinthu ziziyenda bwino. Kumvetsetsa ntchito ya zinthu monga kaboni, chromium, ndi faifi tambala kumathandiza akatswiri a metallurgists ndi mainjiniya kupanga ma forging omwe amakwaniritsa zofunikira pamafakitale osiyanasiyana. Posankha mosamala ndikuphatikiza zinthuzi, opanga amatha kupanga zopanga zapamwamba kwambiri zokhala ndi mphamvu zapamwamba, zolimba, komanso kukana zinthu zachilengedwe, kuwonetsetsa kudalirika komanso moyo wautali pazogwiritsa ntchito.
