Zitsulo zozungulira

Zitsulo zozungulira ndi mtundu wa zitsulo zopangidwa powonjezera gawo lina la zinthu zina zoyatsira kaboni. Zinthu zoyatsirazi zimaphatikizaponso koma sizimangokhala ndi silicon (si), manganese (Mn), Tungsten (W), Cangdium (V). ) Titanium (ti), chromium (cr), nickel (ni), molybdenum (molbdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenum (molybdenu, etc. Malinga ndi zomwe zili pazinthu za Alloy, zitsulo zozungulira zimatha kugawidwa m'magulu atatu: zitsulo zotsika, sing'anga ya chitsulo ndi chitsulo chachikulu. Chosangalatsa chonse cha zitsulo zotsika nthawi zambiri chimakhala zosakwana 5%, zomwe zimapezeka pakati pa 5% ndi 10%, komanso zokongola za zitsulo zapamwamba zimapitilira 10%.

Mu mafakitale othandizira, alloy mozungulira zitsulo zimatha kutumizidwa m'mitundu yambiri malinga ndi zosowa zosiyana ndikugwiritsa ntchito. Mwachitsanzo, zolimbitsa thupi zotsika kwambiri nthawi zambiri zimagwiritsidwa ntchito popanga zida zambiri monga magalimoto, zombo, ndi milatho; Zitsulo zosefukira ndizoyenera kupanga magawo osiyanasiyana ovala monga magiya ndi magiriki chifukwa cha kuuma kwake; Chitsulo chaulere chifukwa cha ntchito yake yabwino kwambiri, nthawi zambiri imagwiritsidwa ntchito pokonza makina osakhalitsa; Chifukwa champhamvu kwambiri komanso kulimba mtima komanso chipilala, chipilala chodzazidwa ndi kukwiya ndi choyenera kupanga magawo ofunikira, monga ma cell a injini ndi ndodo zolumikizira; Chitsulo cha masika chimagwiritsidwa ntchito popanga akasupe osiyanasiyana ndi zinthu zina zotanuka; Kugwedeza chitsulo kumagwiritsidwa ntchito popanga mapepala apamwamba.

Zitsulo zozungulira zimathanso kutchulidwanso malinga ndi kapangidwe kake ndi kutentha kwa kutentha. Mwachitsanzo, malinga ndi zomwe zakhala za kaboni, zimatha kugawidwa kukhala chitsulo chochepa cha kaboni, pakati pa kaboni ndi chitsulo chamoto. Zitsulo zotsika nthawi zambiri zimakhala zosakwana 0,2%%, ili ndi pulasitiki yabwino, ndi yosavuta, ndipo imagwiritsidwa ntchito kwambiri pakupanga unyolo, ma rivets, etc.; Pakatikati-kaboni pamapulogalamu amakhala ndi zokhudzana ndi 0,25% -0.6% ndipo ili ndi mpweya wabwino. Kusintha kwa mafuta ndi kudula magwiridwe antchito, koma osauka owuma, oyenera kupanga magawo azigawo ndi zida zomangira; Zithunzi zapamwamba za carbon zimakhala ndi kaboni pakati pa 0,6% -1.7%, ndipo imatha kuvuta kwambiri ndikugwiritsa ntchito mankhwala oyenera kutentha, zomwe nthawi zambiri zimagwiritsidwa ntchito popanga zida ndi nkhungu.

Kuphatikiza apo, gulu la zitsulo zozungulira zimatha kugawanika malinga ndi mtundu wa chitsulo, monga chitsulo cha kaboni wamba. Zitsulo wamba za kaboni wamba zimakhala ndi zitsulo zambiri zomwe phosphorous ndi sulfure, pomwe panali malire okhwima kwambiri pazinthu izi, ndikuwonetsetsa kuti mphamvu zake zimakhala zabwino.

Ku China, njira zotsatila ndi zida za zitsulo zozungulira zimafotokozedwa bwino. Mwachitsanzo, GB / T 699-2015 imatulutsa ukadaulo wamakhalidwe abwino kwambiri kaboni kwambiri, pomwe gb / t 3077-2015 imatulutsa ukadaulo wa zitsulo zojambula. mkhalidwe. Miyezo iyi imathandizira kuwonetsetsa kuti ndi mawonekedwe a ziwonetsero zozungulira kuti mukwaniritse zosowa za magawo osiyanasiyana osiyanasiyana.

Basi yachitsulo yozungulira imapangidwa ndi mitundu yosiyanasiyana monga A-182, F5, F9, F11, F12 & F91. Izi zimapangidwa ndi zitsulo zosiyanasiyana zachitsulo zomwe zimagonjetsedwa komanso zolimba. Navistar Steel ndi otsogolera ndi opanga zitsulo zozungulirazi.

Zitsulo zozungulira kuzungulira zimathandizanso m'magulu amakono, ndipo mitundu yake ndi zida zake zimathandizira kuti zikwaniritse zovuta zosiyanasiyana komanso zothandizirana. Kaya m'magawo omanga, magalimoto, Aerospace kapena kupanga makina opanga, chitsulo chozungulira ndi zinthu zofunika kwambiri. Kumvetsetsa gulu lazoyimira chachitsulo ndilofunika kwambiri posankha chitsulo choyenera ndikuwonetsetsa kuti ikuyenda bwino.
