ʻO ka ʻōwili anu

ʻO ka'ōwili anuanu: me ka'ōwili kila wela e like me ka mea maka, ma hope o ka pickling e wehe i kaʻili oxide no ka'ōwili mauʻana, ua'ōwiliʻia ka huahana i hoʻopauʻia, no ka paʻakikī anuanu i hanaʻia e ka hoʻololi mauʻana o ka ikaika o ka'ōwili paʻakikī, ka paʻakikī, ka paʻakikī a me ka emiʻana o ka'ilika, no laila e emi iho ka hana stamping, hiki ke hoʻohana waleʻia no nā'āpana deformation maʻalahi. Hiki ke hoʻohana ʻia ka ʻōwili paʻa e like me ka mea maka i ka mea kanu wela wela no ka mea ua hoʻolako ʻia nā ʻāpana galvanizing wela me ka laina annealing. ʻO ke kaumaha o ka wili paʻakikī i ʻōwili ʻia ma ke ʻano he 6 ~ 13.5 tons, coil kila ma ke ana wela, wela ʻōwili pickling coil e holo mau ana. ʻO 610mm ka anawaena o loko.

Nā hiʻohiʻona huahana: No ka mea ʻaʻole i hoʻopili ʻia, ua kiʻekiʻe loa kona paʻakikī (ʻoi aku ka nui o ka HRB ma mua o 90), ʻilihune loa ka hana ʻana o ka mīkini, hiki ke maʻalahi i ka hoʻoheheʻe ʻana ma lalo o 90 degere (perpendicular to the direction of coiling).

No ka ma'alahi'ana, ua hana'ia ka'ōwili anuanu a'ōwili'ia ma ke kumu o ka'ōwili wela a me ka'ōwili. ʻO ka ʻōlelo maʻamau, ʻo ia ke kaʻina o ka ʻōwili wela - pickling - ʻōwili anu.

Hana ʻia ka ʻōwili anuanu e ka pā ʻōwili wela i ka mahana maʻamau, ʻoiai e hoʻomehana ʻia ka pā kila i ka wā o ke kaʻina hana no ka ʻōwili ʻana, akā ua kapa ʻia ʻo ka ʻōwili anuanu. ʻO ka hopena o ka ʻōwili wela ma o ka hoʻololi mau ʻana o ke anuanu o ka ʻōwili anuanu, ʻilihune nā waiwai mechanical, kiʻekiʻe loa ka paʻakikī. Pono e hoʻopili ʻia no ka hoʻihoʻi ʻana i kona mau waiwai mechanical, ʻaʻole i hoʻopili ʻia i kapa ʻia ʻo rolled hard roll. Hoʻohana pinepine ʻia ka ʻōwili paʻa paʻa ʻole e hana me ka ʻole o ka piko ʻana a me nā huahana kikoo.
