1. ʻŌwili Wela
ʻO nā papa hoʻolei hoʻomau a i ʻole nā papa ʻōwili mua e like me nā mea maka, i hoʻomehana ʻia e ka umu hoʻomehana ʻanuʻu, dephosphorization wai kiʻekiʻe i loko o ka wili roughing, ka mea roughing ma ke ʻoki ʻana i ke poʻo, huelo, a laila i loko o ka wili hoʻopau, ka hoʻokō ʻana o ka ʻōwili i kāohi ʻia e ke kamepiula, ʻo ka ʻōwili hope loa ma hope o ka hoʻoluʻu ʻana o ke kahe laminar (ka helu hoʻoluʻu i kāohi ʻia e ke kamepiula) a me ka ʻōwili mīkini wili, lilo i ʻōwili lauoho pololei. ʻO ke poʻo a me ka huelo o ka ʻōwili lauoho pololei he ʻano alelo a me ka huelo iʻa, mānoanoa, ʻilihune ka pololei o ka laulā, aia pinepine ka lihi ʻano nalu, ka lihi pelu, ka hale kiaʻi a me nā kīnā ʻē aʻe. He kaumaha kona kaumaha nui, ʻo ke anawaena o loko o ka ʻōwili kila he 760mm. (Makemake ka ʻoihana hana paipu maʻamau e hoʻohana.) ʻO ka ʻōwili lauoho pololei ma ka ʻoki ʻana i ke poʻo, huelo, ka ʻoki ʻana i ka lihi a me ka ʻoi aku ma mua o hoʻokahi hoʻopololei, pae a me nā laina hoʻopau ʻē aʻe, a laila ʻokiʻoki i ka pā a i ʻole ka ʻōwili hou ʻana, ʻo ia hoʻi: papa kila wela i ʻōwili ʻia, nā ʻōwili kila wela pālahalaha, nā ʻāpana ʻoki lōʻihi a me nā huahana ʻē aʻe. Inā ʻo ka pickling e wehe i ka ʻili oxide a poni ʻia i loko o ka ʻōwili pickled wela i ʻōwili ʻia. Hōʻike ka kiʻi ma lalo nei i kaʻōwili wela.
2. ʻŌwili anu
ʻO nā wili kila i ʻōwili wela ʻia e like me nā mea maka, ma hope o ka pickling e wehe i ka ʻili oxide no ka ʻōwili anu, ʻo ka huahana i hoʻopau ʻia no ka nui o ka paʻakikī i ʻōwili ʻia, ma muli o ka deformation anu mau i hoʻokumu ʻia e ka paʻakikī anu o ka nui o ka paʻakikī i ʻōwili ʻia o ka ikaika, paʻakikī, paʻakikī a me nā hōʻailona plastic e emi ana, ka hōʻino ʻana o ka hana stamping, hiki ke hoʻohana wale ʻia no ka deformation maʻalahi o nā ʻāpana. Hiki ke hoʻohana ʻia ka wili paʻakikī i ʻōwili ʻia e like me nā mea maka no ka mea kanu galvanizing wela-dip, no ka mea ua hoʻonohonoho ʻia ka ʻāpana galvanizing wela-dip me ka laina annealing. ʻO ke kaumaha o ka wili paʻakikī i ʻōwili ʻia ma ke ʻano maʻamau he 6 ~ 13.5 tons, ʻo ke anawaena o loko o ka wili he 610mm. ʻO ka papa ʻōwili anu maʻamau, pono e hoʻomau ka annealing coil (CAPL unit) a i ʻole ka hooded furnace de-annealing treatment, e hoʻopau i ka paʻakikī anu a me ke kaumaha ʻōwili, e hoʻokō i nā waiwai mechanical i kuhikuhi ʻia i nā hōʻailona maʻamau. ʻOi aku ka maikaʻi o ka ʻili o ka papa kila i ʻōwili anu, ke ʻano, a me ka pololei o ka dimensional ma mua o ka papa ʻōwili wela. Hōʻike ke kiʻi ma lalo nei i kaʻōwili anu.
ʻO ka ʻokoʻa nui ma waenakila ʻōwili anu vs kila ʻōwili welaaia i loko o ka ʻenehana hana, ka laulā o ka noi, nā waiwai mechanical a me ka maikaʻi o ka ʻili, a me nā ʻokoʻa kumukūʻai. Eia kahi hoʻolauna kikoʻī:
Ka hana ʻana. Hana ʻia ka ʻōwili wela ma nā mahana kiʻekiʻe, ʻoiai hana ʻia ka ʻōwili anu ma ka mahana o ka lumi. ʻO ka ʻōwili wela ka ʻōwili ʻana ma luna o ka mahana crystallization, ʻoiai ʻo ka ʻōwili anu ka ʻōwili ʻana ma lalo o ka mahana crystallization.
Nā noi. Hoʻohana nui ʻia ke kila ʻōwili wela i nā hale kila a i ʻole nā ʻāpana mīkini, me ke kūkulu ʻana i ke alahaka, ʻoiai ʻoi aku ka hoʻohana ʻia o ke kila ʻōwili anu i ka ʻoihana kaʻa a i ʻole nā mea hana liʻiliʻi, nā mīkini holoi, nā pahu hau, a me nā mea ʻē aʻe, me nā mea kūkulu hale.
Nā ʻano mīkini. ʻOi aku ka maikaʻi o nā ʻano mīkini i ʻōwili anu ʻia ma mua o ka ʻōwili wela, no ka mea, ʻo ke kaʻina hana ʻōwili anu e hoʻopuka i ka hopena paʻakikī a i ʻole ka paʻakikī anu, e hopena ana i ka paʻakikī o ka ʻili o ka pepa i ʻōwili anu ʻia a ʻoi aku ka kiʻekiʻe, akā ʻoi aku ka haʻahaʻa o ka paʻakikī, ʻoiai ʻoi aku ka liʻiliʻi o nā ʻano mīkini o ka pepa i ʻōwili wela ʻia ma mua o ka pepa i ʻōwili anu ʻia, akā ʻoi aku ka maikaʻi o ka paʻakikī a me ka ductility.
ʻAno o ka ʻili. ʻOi aku ka maikaʻi o ke ʻano o ka ʻili o ke kila ʻōwili anu ma mua o ke kila ʻōwili wela, ʻoi aku ka paʻakikī o nā huahana ʻōwili anu a emi iho ka ductile, ʻoiai ʻoi aku ka ʻino o ka ʻili o nā huahana ʻōwili wela.
ʻO ka mānoanoa kikoʻī. ʻOi aku ka lahilahi o nā ʻōwili anu ma mua o nā ʻōwili wela, me ka mānoanoa o nā ʻōwili anu mai 0.3 a 3.5 millimeters, ʻoiai ʻo nā ʻōwili wela mai 1.2 a 25.4 millimeters.
Kumukūʻai: ʻO ka maʻamau, ʻoi aku ke kumukūʻai o ka ʻōwili anu ma mua o ka ʻōwili wela. ʻO kēia no ka mea pono ka ʻōwili anu i ka hoʻohana ʻana i nā lako hana ʻoi aku ka paʻakikī a me ka ʻenehana hana paʻakikī, a hiki i ka hana ʻōwili anu ke loaʻa kahi hopena mālama ʻili maikaʻi aʻe, no laila ʻoi aku ke kiʻekiʻe o ke ʻano o nā huahana ʻōwili anu, ʻoi aku ke kiʻekiʻe o ke kumukūʻai. Eia kekahi, pono ke kila ʻōwili anu i ke kaʻina hana i ka ʻenehana hana ʻoi aku ka paʻakikī a me ka paʻakikī hana kiʻekiʻe, ʻoi aku ke kiʻekiʻe o nā lako hana, nā ʻōwili a me nā koi lako ʻē aʻe, kahi e alakaʻi ai i ka piʻi ʻana o nā kumukūʻai hana.
