Hahi i nā ʻāpana 5
Ke noi ʻana i nā ʻāpana hahi
1. Nā ʻāpana uila uila hahi. ʻO kēia ʻano hale hana he ʻoihana hou, e hoʻomohala me ka hoʻomohala ʻana i nā mīkini uila. Hoʻokomo nui ʻia kēia mau hale hana i ka hema.
2. ʻO nā ʻāpana kaʻa a me nā ʻāpana ʻē aʻe i hahi. Hoʻokumu ʻia ia e ka paʻi ʻana a me ka hoʻopaʻa ʻana. ʻO ka hapa nui o kēia mau ʻoihana i nā hale hana maʻamau a me nā mea kanu huki kūʻokoʻa. I kēia manawa, nui nā hale hana liʻiliʻi e pili ana i nā hale hana kaʻa a i ʻole nā mīkini tractor.
3. Hahi ʻana i ka ʻoihana kaʻa. ʻO ke kaha kiʻi ke ʻano nui. I Kina, hoʻohui pinepine ʻia kēia ʻāpana i nā hale hana kaʻa, nā hale hana kaʻa kaʻa, nā mea hana mokulele a me nā hale hana nui ʻē aʻe, a kākaʻawale ka huki nui ʻana a me nā kiʻi ʻana i nā mea kanu.
4. Hina pono kēlā me kēia lā hahi. ʻO kekahi mau hana lima, nā papa ʻaina a pēlā aku, ua ulu nui kēia mau hale hana i nā makahiki i hala iho nei.
5. Nā hana hahi kūikawā. ʻO kahi laʻana, ʻo ka hahi ʻana o nā ʻāpana mokulele no kēia ʻano ʻoihana, akā ua hoʻopili pū ʻia kēia mau hale hana i kekahi o nā hale hana nui.
6. Hahi hahi no nā ʻāpana uila o ka home. Ua ʻike ʻia kēia mau hale hana ma hope o ka hoʻomohala ʻana o nā mīkini home ma Kina, a hāʻawi ʻia ka hapa nui o lākou i nā ʻoihana mīkini home.
Nā ʻenehana pono no nā ʻāpana hahi hao
1. Hoʻohana ʻia ka hoʻomākala kemika a me nā hoʻokolohua metallographic e kālailai i nā ʻike o nā mea kemika i nā mea, hoʻoholo i ka papa a me ka lōkahi o ka nui o ka palaoa, loiloi i ka papa o ka semite manuahi, nā hana i hoʻopaʻa ʻia a me nā mea hao ʻole i loko o nā mea, a nānā i ka nā kīnā e like me ka shrinkage lua a me ka porosity. 2. Nānā i nā mea hana o nā wahi hahi i ka nui-i ʻōwili ʻia a i ʻōwili ʻia (anuanu ʻia) i pepa a me nā mea ʻili. E hoʻolako ʻia nā mea hana o nā wahi hahi metala me nā palapala hōʻoia maikaʻi e hōʻoia i ka hoʻokō ʻana o nā pono i nā koi ʻenehana i ʻōlelo ʻia. Ke ʻaʻohe palapala maikaʻi a no nā kumu ʻē aʻe paha, hiki i ka mea hana hahi i nā ʻāpana hana ke koho i nā mea maka no ka nānā hou ʻana e like me nā pono. ʻAno o
3. ʻO ka hoʻāʻo formability komo pūlou hoʻokolohua, kīʻaha kīʻaha, hoʻoholo o ka hana ʻoʻoleʻa papa kuhikuhi n a me ka pīlali kānana lākiō R. me ka hoʻohui, ka formability hōʻike hana o ke kila kuina hiki ke hoʻokō 'ia e like me nā rula o ka formability a me ka hoao hana o ka pepa kila . ʻAno o
4. Hōʻike ka paʻakikī i ka paʻakikī o nā ʻāpana hahi metala e hoʻāʻo ʻia e Rockwell hardness tester. Hiki ke hoʻohana ʻia i nā ʻāpana hahi liʻiliʻi e hoʻāʻo ai i ka mokulele he liʻiliʻi loa, ʻaʻole hiki ke hoʻāʻo ʻia ma ka papa ʻaina ʻo Rockwell hardness tester.
