ʻO ka hana ʻana i nā flanges kila kalaponama kahihana anu anu is hoʻopunipunii ka haʻahaʻa wela, ka nui o kaflange forgedliʻiliʻi liʻiliʻi. I ka manawake kalai ana ma lalo700 ℃, hoʻokumu ʻia ka pālākiō liʻiliʻi a ʻaʻohe decarbonization ma ka ʻili. No laila, e like me ka lōʻihi o ka deformation hiki i loko o ka hana ikehu laulā, anu forging mea maʻalahi i ka maikai dimensional pololei a me ka ili pau. I ka lōʻihi o ka mālama ʻana i ka mahana a me ka lubrication cooling, hiki ke loaʻa i ka pololei maikaʻi i ka hoʻoulu ʻana i ka mahana a hiki i 700 ℃.Ke anuu make forging, extrusion anu, poʻomanaʻo anu a me nā hana plastik ʻē aʻe i hui pū ʻia. ʻO ka hoʻoheheʻe anuanu ke kaʻina hana ma lalo o ka wela o ka recrystallization o ka mea, a lawe ʻia ka forging ma lalo o ka mahana hoʻihoʻi. I ka hana ana, kake kalaiwa anaʻo ka pāpaʻa ʻole i hoʻomehana ʻia, ua kapa ʻia ʻo cold forging. ʻO nā mea i hoʻoheheʻe ʻia i ke anuanu ka hapa nui o ka aluminika a me kekahi mau ʻāpana, keleawe a me kekahi mau ʻāpana, ke kila kalapona haʻahaʻa, ke kila kalapona liʻiliʻi a me ke kila kila haʻahaʻa haʻahaʻa me ke kūpaʻa deformation haʻahaʻa a me ka plasticity maikaʻi i ke ana wela. He maikaʻi ka maikaʻi o ka ʻili o ka ʻili anu, ka pololei kiʻekiʻe a hiki ke hoʻololi i kekahi ʻoki. Hoʻoikaika ka hana anuanu i ka metala a hoʻonui i ka ikaika o ka flange.
ʻO ka hoʻomohala ʻana i ka ʻenehana forging anuanu ka mea nui e hoʻomohala i nā huahana kiʻekiʻe i hoʻohui ʻia, e hoʻemi i nā kumukūʻai hana, i ka manawa like, ʻo ia hoʻi e ʻoki mau ʻia, pauka metallurgy, hoʻolei ʻana, wela forging, sheet metal forming process a me nā wahi ʻē aʻe o ke komo ʻana a i ʻole. hoʻololi, hiki ke hui pū me kēia mau kaʻina hana e hana i kahi kaʻina hana.

ʻO kahoʻopaʻa ʻana i nā flangesʻo ia: i ka wāhoʻopaʻa wela, nā lehelehe nuime nā ʻano paʻakikī hiki ke hana ʻia no ka mea liʻiliʻi loa ka ikehu deformation a me ke kūpaʻa deformation. No nā flanges kikoʻī kiʻekiʻe, loaʻa ka hoʻoheheʻe wela ma ka pae wela 900-1000 ℃. Eia kekahi, pono e uku ʻia ka nānā ʻana i ka hoʻomaikaʻi ʻana i ke ʻano hana o ka forging wela. Forging make ola (wela forging 2-5 tausani, mehana forging 10-20 tausani, anu forging 20-50 tausani) ua pōkole ma mua o ka wela wahi forging, akā, he nui degere o ke kuokoa, haʻahaʻa kumu kūʻai. ʻO ke kumu o ka wela forging flange ka mea nui e hōʻemi i ke kūpaʻa deformation o ka metala, i mea e hōʻemi ai i ka deformation mea ʻino e pono ai ke kaomi forging, i hoʻemi nui ʻia ka tonnage o nā mea hana forging; I ke kaʻina hana o ka hoʻoulu ʻana i ka wela, ua hoʻololi ʻia ke ʻano koʻikoʻi o ka ingot kila i hale hou me nā hua maikaʻi ma o ka recrystallization, a hoʻemi ʻia nā hemahema o ka hale a hoʻomaikaʻi ʻia nā ʻano mechanical o ke kila.
