I ka honua o ka hana kila, hoʻohana pinepine ʻia nā huaʻōlelo "hot rolled" a me "cold rolled" e wehewehe i nā kaʻina hana a me nā huahana like ʻole. Ma Jindalai Steel Company, haʻaheo mākou iā mākou iho i ka hāʻawi ʻana i nā mea hoʻonā kila kiʻekiʻe, ʻo ia hoʻi nā pā kila wela, nā pā kila i ʻōwili ʻia, nā pā kila kalapona i ʻōwili ʻia, nā pā kila kila i ʻōwili ʻia, a me nā wili ʻili anu. He mea nui ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau huahana no ka hoʻoholo ʻana i kāu mau papahana.
“Papa kila i olokaa wela vs. pa kila i owiliia”
ʻO ka ʻokoʻa mua ma waena o nā papa kila i ʻōwili ʻia a me ke anuanu aia ma ke kaʻina hana. Hana ʻia nā pā kila ʻōwili wela e ka ʻōwili kila ma nā wela kiʻekiʻe, ʻoi aku ma mua o 1,700°F. ʻO kēia kaʻina hana e hiki ai i ke kila ke hana maʻalahi a hoʻokumu ʻia, e hopena i kahi huahana i emi ke kumukūʻai a ʻoi aku ka paʻa o ka ʻili. He mea kūpono nā pā kila wela no nā noi kahi ʻaʻole koʻikoʻi nā ana kikoʻī, e like me nā mea hana a me nā mīkini kaumaha.
ʻO ka ʻokoʻa, hana ʻia nā papa kila i ʻōwili ʻia i ka lumi wela, kahi e hoʻopau ai i ka hoʻopau ʻana o ka ʻili a ʻoi aku ka paʻa. ʻO ke kaʻina hana anuanu e hoʻonui i ka ikaika a me ka paʻakikī o ke kila, e kūpono i nā noi e pono ai ka pololei a me ka lōʻihi. Hoʻohana pinepine ʻia nā papa kila i ʻōwili ʻia i nā ʻāpana kaʻa, nā mea hana, a me nā huahana ʻē aʻe kahi i ʻoi aku ka maikaʻi a me ka hana.
“Papa kila kabone i ʻōwili ʻia ma mua o nā pā kila kuhili ʻole.
I ka wā e pili ana i ke kila ʻōwili anuanu, ʻelua ʻano kumu mua: nā papa kila kalapona i ʻōwili ʻia a me nā pā kila kuhili. ʻIke ʻia nā papa kila kalapona ʻōwili anuanu no ko lākou ikaika maikaʻi loa a me ka hoʻohālikelike ʻana, e hana ana iā lākou i koho kaulana no ke kūkulu ʻana a me nā noi hana. ʻOi aku ka maʻalahi o lākou ma mua o kā lākou mau mea kila kila, e lilo ai lākou i koho maikaʻi no nā papahana ʻike kālā.
Ma ka ʻaoʻao ʻē aʻe, hāʻawi nā papa kila kuʻikuʻu i ʻōwili ʻia i ke kūpaʻa maikaʻi a me ka hoʻopiʻi nani. He mea maikaʻi kēia mau papa no nā noi i loko o nā wahi paʻakikī, e like me ka hana kemika a me ka hana ʻana i ka meaʻai, kahi e hopohopo ai ka ʻike ʻana i ka makū a me nā kemika. ʻO ke koho ʻana ma waena o ke kila kila a me ke kila kila ʻili anuanu ma muli o nā koi kikoʻī o kāu papahana.
"ʻO nā pono o ke kaʻina hana ʻo Cold Rolling"
Hāʻawi ke kaʻina ʻōwili anu i nā mea maikaʻi ma mua o ka ʻōwili wela. ʻO ka mea mua, loaʻa ia i kahi hoʻopau maʻemaʻe o ka ʻili, pono ia no nā noi kahi e pono ai ke ʻano. ʻO ka lua, hōʻike nā huahana ʻōwili anu i nā waiwai mechanical i hoʻonui ʻia, me ka hoʻonui ʻana i ka ikaika a me ka paʻakikī. ʻO kēia ka mea i kūpono i nā pā kila a me nā wili anuanu no nā noi koi.
Hoʻohui ʻia, hoʻolako pinepine ʻia nā coils ʻōwili anuanu e nā mea hana e like me Jindalai Steel Company, e hōʻoia ana e loaʻa iā ʻoe nā huahana kiʻekiʻe i kūpono i kāu mau pono. ʻO kā mākou kūpaʻa i ka maikaʻi, ʻo ia ka mea hiki iā ʻoe ke hilinaʻi i kā mākou mau makana kila ʻōwili anuanu e hoʻokō i nā kūlana ʻoihana kiʻekiʻe.
“Hoʻopau”
I ka hōʻuluʻulu manaʻo, ʻo ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o nā pā kila i ʻōwili ʻia a me ke anuanu he mea koʻikoʻi no ke koho ʻana i nā mea kūpono no kāu papahana. Ua hoʻolaʻa ʻia ʻo Jindalai Steel Company i ka hoʻolako ʻana i ka laulā o nā huahana kila, e komo pū ana me nā pā kila wela, nā pā kila kalapona i ʻōwili ʻia, nā ʻāpana kila i hoʻoheheʻe ʻia, a me nā wili ʻōwili anuanu. Ma ke koho ʻana i kā mākou huahana, hiki iā ʻoe ke hilinaʻi i ka maikaʻi a me ka hana o kāu mau hoʻonā kila. No ka ʻike hou aku e pili ana i kā mākou hāʻawi, e kipa i kā mākou pūnaewele a i ʻole e kelepona i kā mākou hui kūʻai i kēia lā.
