Pehea e koho ai i nā hoʻomaʻamaʻa kaumaha?

Na apo apoʻo ka ʻōwili ʻana i kanā kalaiwai loko o ka pōʻai, hiki ke hoʻomalu i ka dimensional tolerance o ka huahana, hoʻemi i ka nui o ka mīkini. Eia nō naʻe, i ke koho ʻana i nā forging apo, pono mākou e makaʻala ʻaʻole e koho i nā forgings apo hemahema. Inā koho nui ʻia ka hoʻohana ʻana o ka papahana i ke koho ʻana i nā apo apo hewa, e loaʻa pū kekahi mau pilikia. A laila, pehea e koho ainā kalaiwa kaumaha?

ʻO ka mea mua, e nānā i ka ʻili o ka hoʻoheheʻe ʻana: inā he mau māwae ka ʻili, peʻa, ʻili, nā lua kaomi, ʻili ʻalani, ʻūhū, nā kiko, nā lua ʻino, nā ʻōpala, nā mea haole, ʻaʻole piha, lua, nele i ka ʻiʻo, ʻōpala. a me nā hemahema ʻē aʻe, ʻōlelo ʻia ʻaʻole ʻoe e kūʻai.

ʻO ka ʻimi ʻana i ka nui o ka ʻae mīkininā kalaiwa kaumahaloaʻa nō hoʻi nā koi kūpono no ka mea o nā forgings kaumaha. ʻAʻole hiki ke hoʻohana ʻia nā bila e like me ka forgings no ka forging and processing. Pono e hoʻopaʻa ʻia ka ratio forging o nā ʻāpana me nā ʻano like ʻole, a ʻo ka hana ʻana o ke kila pōʻai me ka nui like ʻaʻole pono e hoʻokō i nā koi koʻikoʻi i ke kaʻina hana forging, e like me ka mahana, ka hoʻoulu pinepine ʻana a me ke kaomi. ʻO nā kristal metala i lokonā kalaiwa kaumahaʻoi aku ka maikaʻi a ʻoi aku ka paʻa o ka ʻoki ʻia, a ua hana ʻia nā forgings me ka ʻole o ka hōʻino ʻana i nā fiber metala o ka mea maka a hiki ke hoʻomāmā i nā laina metala.

ʻO kēia mau pono onā kalaiwa kaumahaʻaʻole e kamaʻilio ʻia, akā ma muli o kā lākou koi ʻenehana koʻikoʻi. Ka nui kaawale oapo kaumaha forgingse kūlike me nā kūlana palekana honua, a pono e kūlike ka mea me nā mea o nā ʻāpana. E kū like ka haku mele ʻana me nā kūlana hoʻohui aupuni a e hoʻopuka ʻia ka papa inoa mea. ʻO ke ala nui e hōʻemi ai i ka ʻike hydrogen i loko o ke kila ʻo ka hoʻoheheʻe ʻana a i ʻole ka ninini ʻana o ke kila wai i ka wā o ka hana kila. No kekahi mau forgings me nā koi kiʻekiʻe, hiki ke hoʻohana ʻia ke kaʻina hana electroslag remelting e hoʻomaikaʻi hou i ka maʻemaʻe o ke kila. Hoʻomaʻamaʻa wela ma hope o ka hana ʻana: Dehydrogenation annealing e hoʻoheheʻe ʻia ka hydrogen mai ke kila.
