1. Ke hana kiola: He hana hana kuʻuna kēia. Pono ia i kahi hoʻonohonoho piha o ka smelting, ka ninini ʻana a me nā pono hana ʻē aʻe. Pono ia i kahi mea kanu nui a nui aku nā limahana. Pono ia i ka hoʻopukapuka nui, nā hana he nui, nā kaʻina hana paʻakikī, a me ka haumia. ʻO ke kaiapuni a me ke kūlana mākau o nā limahana i kēlā me kēia kaʻina hana e hoʻopili pololei i ka maikaʻi o ka huahana. ʻAʻole hiki ke hoʻonā piha i ka pilikia o ka liu ʻana o nā pores o nā ʻāpana kila kila. Eia nō naʻe, nui ka ʻāpana hakahaka hakahaka a nui ka ʻōpala, a ʻike pinepine ʻia ka hana ʻana i nā hemahema hoʻolei iā ia i ka wā o ka hana ʻana. , E like me ka hoʻonui ʻana o ke kumukūʻai huahana a ʻaʻole hiki ke hōʻoia ʻia ka maikaʻi, ʻaʻole kūpono kēia hana no kā mākou hale hana.
2. Ke hana hoʻopunipuni: ʻO kēia kahi hana i hoʻohana ʻia e nā hui kiwikā home he nui. ʻElua ona ʻano hana: hoʻokahi e ʻoki a wela i ka forge i loko o kahi spherical solid blank me ke kila a puni, a laila hana i ka hana mīkini. ʻO ka lua e kāpili i ka pā kila kila pōʻaiapuni ma kahi kaomi nui e loaʻa ai kahi hakahaka hemispherical hollow, a laila hoʻopili ʻia i kahi ākea spherical no ka hana mīkini. ʻOi aku ka kiʻekiʻe o ka hoʻohana ʻana o kēia meahana, akā he mana kiʻekiʻe ʻO ke kaomi, hoʻomehana umu a me nā pono hoʻoheheʻe argon i manaʻo ʻia e koi i kahi hoʻopukapuka o 3 miliona yuan e hana i ka hana. ʻAʻole kūpono kēia hana no kā mākou hale hana.
3. Ke kaʻina wili: ʻO ke kaʻina wili keleawe kahi hana hana mua me ka liʻiliʻi a ʻaʻohe ʻāpana. He lālā hou ia o ka hana kaomi. Hoʻohui ia i nā ʻano o ka forging, extrusion, rolling and rolling, a he mea hoʻohana kiʻekiʻe (Up to 80-90%), e mālama nei i ka manawa hana (1-5 mau minuke e hana ana), hiki ke pāpālua ʻia ka ikaika o nā mea ma hope o ka wili. Ma muli o ka liʻiliʻi o ka pili ma waena o ka huila kaʻapuni a me ka mea hana i ka wā o ka wili, aia nā mea metala i kahi ʻaoʻao ʻelua a i ʻole ʻekolu mau ala compressive stress, kahi maʻalahi e deform. Ma lalo o kahi mana liʻiliʻi, kahi stress contact contact unit (ʻoi aku i ka 2535Mpa) No laila, māmā nā lako i ke kaupaona a me ka nui o ka mana e pono ai (liʻiliʻi ma mua o 1/5 a 1/4 o ka paʻi). I kēia manawa ʻike ʻia e ka ʻoihana kiwikā haole ma ke ʻano he ʻenehana ʻenehana spherical-sphere hana ʻenehana, a he kūpono hoʻi ia no ka hana ʻana i nā ʻāpana hakahaka hollow. Ua hoʻohana ākea ʻia ka ʻenehana wili a hoʻomohala ʻia ma kahi wikiwiki kiʻekiʻe ma nā ʻāina ʻē. ʻO kaʻenehana a me nā lakohana he oʻo loa a paʻa hoʻi, a ʻike ʻia ka kaomi aunoa o ka hoʻohui o ka mīkini, uila a me ka neʻe. I kēia manawa, ua hoʻomohala nui ʻia ka ʻenehana wili i koʻu ʻāina a ua komo i ke kahua o ka hoʻolaha a me ka hana.
