I ka honua o ka hana ʻana metala, pāʻani nui nā pā keleawe a me nā pā keleawe ma waena o nā ʻoihana like ʻole, me ke kūkulu ʻana, ka ʻenekini uila, a me ka hydropower. Ma ke ʻano he mea pāʻani nui ma kēia ʻāpana, kū ʻo Jindalai Steel Company i waena o nā mea hana pā keleawe, e hāʻawi ana i nā ʻano huahana like ʻole i hoʻohālikelike ʻia e hoʻokō i nā pono o nā noi like ʻole. E ʻimi ana kēia blog i nā ʻano pā keleawe like ʻole, nā kumukūʻai, a me nā kaʻina hana i kā lākou hana ʻana, me ka hōʻike pū ʻana i ke koʻikoʻi o kēia mau mea i ka ʻenehana hydropower.
ʻO ka hoʻomaopopo ʻana i nā pā keleawe a me ko lākou mau ʻano
ʻO nā pā keleawe he mau mea koʻikoʻi i ʻike ʻia no kā lākou conductivity maikaʻi loa, kūpaʻa corrosion, a me ka malleability. Hoʻohana nui ʻia lākou i nā noi uila, plumbing, a me nā hoʻolālā hale. Ma waena o nā ʻano pā keleawe like ʻole i loaʻa, ʻo ka mea kaulana loa:
H62 Papa keleawe
ʻO ka pā keleawe H62 kahi koho kaulana i waena o nā mea hana ma muli o kāna mau mea mechanical maikaʻi loa a me ka pale ʻana i ka corrosion. Hoʻokumu mua ʻia me ke keleawe a me ka zinc, ʻike ʻia ke keleawe H62 no kona machinability maikaʻi a me ka weldability. Hoʻohana pinepine ʻia i nā noi e koi ana i ka ikaika kiʻekiʻe a me ka lōʻihi, e like me nā mea pono, nā valves, a me nā lako kai. Hiki ke ʻokoʻa ke kumu kūʻai o nā pā keleawe H62 e pili ana i ka mānoanoa, ka nui, a me ka makemake o ka mākeke, no laila he mea nui i ka poʻe kūʻai aku e noho ʻike e pili ana i nā kumukūʻai pā keleawe o kēia manawa.
T2 Papa keleawe
ʻO nā pā keleawe T2 kekahi huahana koʻikoʻi i hāʻawi ʻia e nā mea hana pā keleawe. ʻO kēia keleawe maʻemaʻe kiʻekiʻe, me ka liʻiliʻi o ka maʻi keleawe o 99.9%, kaulana ʻia no kāna hana uila a me ka wela. Hoʻohana pinepine ʻia nā pā keleawe T2 i nā ʻāpana uila, nā mea hoʻololi wela, a me nā noi ʻoihana like ʻole. Ke piʻi aʻe nei ke koi no nā pā keleawe T2, e alakaʻi ana i nā loli i nā kumukūʻai pā keleawe. Pono nā mea kūʻai aku e noʻonoʻo i ka loaʻa ʻana mai nā mea hana kaulana e hōʻoia i ka loaʻa ʻana o nā huahana kiʻekiʻe ma nā kumukūʻai hoʻokūkū.
Papa keleawe ulaula
ʻO nā pā keleawe ʻulaʻula, i hōʻike ʻia e ko lākou ʻulaʻula ʻulaʻula, i hana ʻia mai ke keleawe maʻemaʻe kiʻekiʻe a ua ʻike ʻia no ko lākou maikaʻi wela a me ka uila. Hoʻohana pinepine ʻia kēia mau papa i nā noi e like me nā mea kuke, nā uila uila, a me nā mea hoʻonaninani. ʻO ka hoʻopiʻi aesthetic o nā pā keleawe ʻulaʻula e lilo lākou i koho kaulana i nā hana hana a me nā noi. E like me nā huahana keleawe ʻē aʻe, hiki ke ʻokoʻa nā kumukūʻai ma muli o nā kūlana mākeke a me nā koi kikoʻī o ka mea kūʻai aku.
Pāpā keleawe-ʻole o ka oxygen
Hana ʻia nā pā keleawe ʻole o ka oxygen ma o kahi kaʻina hana kūikawā e hoʻoneʻe i ka oxygen mai ke keleawe, e hopena i kahi mea me ka conductivity kiʻekiʻe a me ke kūpaʻa ʻana i ka embrittlement. He kūpono kēia mau papa no nā noi hana kiʻekiʻe, me nā leo leo a me nā mea wikiō, kahi i mea nui ai ka hōʻailona hōʻailona. ʻOi aku ka paʻakikī o ka hana ʻana o nā pā keleawe ʻole oxygen, hiki ke hoʻololi i kā lākou kumukūʻai. Eia nō naʻe, ʻo nā pōmaikaʻi a lākou e hāʻawi pinepine ai e hōʻoia i ka hoʻopukapuka kālā no nā ʻoihana e koi ana i ka hana kiʻekiʻe.
ʻO ke kuleana o nā pā keleawe i ka ʻenekinia hydropower
Hoʻohana nui ʻia nā pā keleawe i ka ʻenehana hydropower ma muli o kā lākou conductivity maikaʻi loa a me ke kū ʻana i ka corrosion. I loko o nā mea kanu hydropower, hoʻohana pinepine ʻia nā pā keleawe i nā ʻāpana uila, e like me nā mea hana a me nā mea hoʻololi, kahi mea koʻikoʻi ka hoʻololi ʻana i ka ikehu. ʻO ka lōʻihi a me ka hilinaʻi o nā pā keleawe e hoʻolilo iā lākou i koho kūpono no ia mau ʻano koi.
Ke hoʻomau nei ka noi no nā kumu ikehu hou, ke manaʻo nei e hoʻonui ka hana o nā pā keleawe i ka ʻenehana hydropower. Hoʻokumu nā mea hana e like me Jindalai Steel Company i ka hāʻawi ʻana i nā pā keleawe kiʻekiʻe e kū ana i nā kūlana koʻikoʻi i koi ʻia no kēia mau noi.
Ke Kaʻina Hana Hana ʻana i nā pā keleawe
ʻO ka hana ʻana o nā pā keleawe e pili ana i nā kaʻina hana koʻikoʻi, e hōʻoia ana e hoʻokō ka huahana hope i nā kikoʻī e pono ai no nā noi like ʻole. Eia kahi ʻike pōkole o ke kaʻina hana maʻamau:
1. Hehee: Hoʻoheheʻe ʻia nā ʻōpala keleawe a i ʻole nā ingots i loko o ka umu e hoʻokō ai i ka maʻemaʻe a me ka haku mele.
2. Ka hoʻolei ʻana: Ua ninini ʻia ke keleawe i hoʻoheheʻe ʻia i loko o nā mole e hana i nā papa a i ʻole nā billet, a ma hope e hana ʻia i mau papa.
3. Rolling: Hoʻomaʻamaʻa ʻia nā papa i hoʻolei ʻia a hele ma waena o nā wili e hoʻokō ai i ka mānoanoa a me nā ana i makemake ʻia. ʻO kēia kaʻina hana hoʻi e hoʻonui i nā pono mechanical o ke keleawe.
4. Annealing: Hoʻopili ʻia nā papa i ʻōwili ʻia i ka mālama wela e hoʻomaha i nā koʻikoʻi o loko a hoʻomaikaʻi i ka ductility.
5. Hoʻopau: ʻO ka hope, e hoʻomaʻamaʻa ʻia nā papa e wehe i nā haumia a hoʻokō i ka hopena i makemake ʻia.
Ka hopena
I ka hopena, ʻo nā pā keleawe he mau mea pono i nā ʻoihana like ʻole, a ʻo ka hoʻomaopopo ʻana i nā ʻano like ʻole i loaʻa he mea koʻikoʻi no ka hoʻoholo ʻana i nā hoʻoholo kūʻai. ʻO Jindalai Steel Company, ma ke ʻano he mea hana nui o ka pā keleawe, ke hāʻawi aku nei i ka nui o nā huahana, me nā pā keleawe H62, nā pā keleawe T2, nā pā keleawe ʻulaʻula, a me nā pā keleawe ʻole oxygen, nā mea āpau ma nā kumukūʻai hoʻokūkū.
Ke hoʻomau nei ka piʻi ʻana o ka noi no nā pā keleawe kiʻekiʻe, ʻoi aku hoʻi i nā ʻāpana e like me ka ʻenehana hydropower, pono ia i nā mea kūʻai aku e hoʻomau hou i nā ʻano mākeke a me nā kumukūʻai. Ma ka launa pū ʻana me nā mea hana kaulana, hiki i nā ʻoihana ke hōʻoia e loaʻa iā lākou nā huahana maikaʻi loa e hoʻokō i kā lākou mau pono kikoʻī. Inā makemake ʻoe i nā pā keleawe no nā noi uila a i ʻole nā papahana hydropower, ʻo Jindalai Steel Company kāu kumu hilinaʻi no ka maikaʻi a me ka hilinaʻi.
