E pili ana i Hot rolled

ʻO ka ʻōwili wela e pili ana i ka ʻōwili anu, ʻo ka ʻōwili anu ma lalo o ka mahana crystallization, a ʻo ka ʻōwili wela ke ʻōwili ʻia ma luna o ka mahana crystallization.

ʻIke ʻia hoʻi, ka pā wela, ka pā ʻōwili wela.Hoʻohana ʻia nā pāpaʻi wela i ka hoʻoheheʻe ʻia ʻana a i ʻole nā ​​​​palapala mohala ma ke ʻano he mea maka, i hoʻomehana ʻia e ka umu hoʻomehana hele, hoʻohaʻahaʻa i ka wai kiʻekiʻe, a laila e komo i ka wili wili.ʻOki ʻia ke poʻo, huelo, a laila komo i ka wili wili hoʻopau no ka mana kamepiula.ʻO ka ʻōwili ʻana, ma hope o ka ʻōwili hope ʻana, e loaʻa iā ia ka hoʻoluʻu laminar (ka helu hoʻoluʻu i hoʻomalu ʻia e ka kamepiula a me ka wili ʻana e ka coiler e lilo i wili lauoho pololei.
Pōmaikaʻi

□ Pono
(1) Hiki i ka ʻōwili wela ke hōʻemi nui i ka hoʻohana ʻana i ka ikehu a hoʻemi i nā kumukūʻai.I ka wā wela, he kiʻekiʻe ka plasticity o ka metala a me ke kūpaʻa deformation haʻahaʻa, e hōʻemi nui ana i ka hoʻohana ʻana i ka ikehu o ka deformation metala.

(2) Hiki i ka ʻōwili wela ke hoʻomaikaʻi i ka hana hana ʻana o nā metala a me nā ʻāpana, ʻo ia hoʻi, ua haki nā ʻōpala i loko o ke kūlana as-cast, ua hoʻōla nui ʻia nā māwae, ua hoʻemi ʻia a hoʻopau ʻia nā hemahema o ka hoʻolei ʻana, hoʻololi ʻia i loko o ka hale deformed, a hoʻomaikaʻi ʻia ka hana ʻana o ka alloy.

(3) Hoʻohana maʻamau ka ʻōwili wela i nā ingots nui a me ka hoʻohaʻahaʻa nui ʻana, ʻaʻole ia e hoʻomaikaʻi wale i ka hana hana, akā hana pū kekahi i nā kūlana no ka hoʻonui ʻana i ka wikiwiki o ka ʻōwili a ʻike i ka hoʻomau a me ka automation o ke kaʻina hana.

□ Hoʻokaʻawale
Hoʻokaʻawale ʻia nā papa kila i ʻōwili ʻia i ke kila kila, ke kila kalapona haʻahaʻa a me ke kila ʻōmole welded.ʻO ka pepa kila i'ōwiliʻia he haʻahaʻa paʻakikī, hana maʻalahi a me ka ductility maikaʻi.He haʻahaʻa ka ikaika o ka pā kila wela, a ʻilihune ka maikaʻi o ka ʻili (oxidation\low finish), akā maikaʻi ka plasticity.ʻO ka mea maʻamau, ʻo ia ka pā waena a me ka mānoanoa, ka pā anuanu, ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka hoʻopau ʻana i ka ʻili kiʻekiʻe, a me ka pā lahilahi maʻamau, hiki ke hoʻohana ʻia e like me ka hoʻohana ʻana i ka papa.

Ka nui kiko'ī

Pono ka nui o ka pā kila e hoʻokō i nā koi o ka papa "Dimensions and Specifications of Hot Rolled Steel Plates (Excerpted from GB / T709-2006)".
Hiki i ka laulā o ka pā kila ke nui o 50mm a i ʻole ka nui o 10mm, a ʻo ka lōʻihi o ka pā kila he 100mm ka nui a i ʻole ka nui o 50mm, akā ʻo ka liʻiliʻi loa o ka pā kila o ka mānoanoa ma lalo o a i ʻole. e like me 4mm ʻaʻole e emi iho ma mua o 1.2m, a ʻo ka lōʻihi haʻahaʻa loa o kahi pā kila o ka mānoanoa ʻoi aku ma mua o 4mm ʻaʻole ia e emi iho ma mua o 2m.E like me nā koi, ʻoi aku ka mānoanoa o ka pā kila ma lalo o 30mm, hiki ke 0.5mm ka mānoanoa.E like me nā pono, ma hope o ke kūkākūkā ʻana ma waena o ka mea hoʻolako a me ka mea kūʻai aku, hiki ke hāʻawi ʻia i nā pā kila a me nā ʻāpana o nā nui ʻē aʻe.
