Hoʻohana nā mea huahana i ke kūlana aupuni, e like me ka pā kila.Hoʻonohonoho ʻia nā kūlana maikaʻi a me nā ʻenehana a hana ʻia e like me ka maʻamau YB/T4212-2010 (Q345B/Q235B e nānā iā GB/T1591-94, kēlā me kēia.
1. He kila lō'ihi i 'ōwili 'ia me ka 'ao'ao 'ehā no ka ho'ohana ma'amau.Hōʻike ʻia kāna mau kikoʻī i nā millimeters o ka mānoanoa * ākea.Hiki ke hoʻopau ʻia ke kila pālahalaha, hoʻohana ʻia no nā ʻāpana, nā alapiʻi, nā alahaka a me nā pā, a me nā mea ʻē aʻe.(Material: Q215, Q235), hoʻokō maʻamau: GB704-1988 ma kahi o GB704-83, pili kēia maʻamau i ka mānoanoa o 3 ~ 60mm, laula o 10 ~ 200mm, rectangular cross-section o ke kumu nui wela-rolled kila pālahalaha. .Ke kūlana hoʻouna: Hāʻawi ʻia ke kila pālahalaha ma nā kaola pololei.Ana: Hāʻawi ʻia ke kila pālahalaha o ka lōʻihi paʻa a me ka lōʻihi o nā kāne e ke kaumaha theoretical.
2. ʻO ke kila paʻa paʻa i hoʻopaʻa ʻia he pā kila lōʻihi me ka ʻāpana kea ʻehā.ʻAʻole hiki i ka Forging ke loaʻa i kahi ʻano a me ka nui o ka forgings, akā hiki nō hoʻi ke hoʻomaikaʻi maikaʻi i ka hui kila kila, hoʻomaikaʻi i ka nui o ke kila;hiki ke hoʻololi i ka mahele o ka hui fiber, wehe i ka anisotropy, hoʻomaikaʻi i nā waiwai mechanical o ka metala, i hoʻomaikaʻi ʻia ka ikaika a me ka paʻakikī o ke kila;a hiki ke hana i ka plasticity ka haʻahaʻa i ke kila kiʻekiʻe a me ke kila kila kiʻekiʻe.ʻO ke kila paʻa paʻa paʻa ke kila kila kiʻekiʻe, hoʻohana nui ʻia no nā pūnāwai, nā mea hana a me nā ʻāpana mechanical koʻikoʻi.Hōʻike ʻia ka kikoʻī o ke kila pālahalaha i hoʻopaʻa ʻia i ka mm o ka mānoanoa * ākea, a ʻo ka kikoʻī he 20mm * 40mm ~ 160mm * 300mm.kūlana hoʻokō: GB/T16761-1
ʻO ka ʻāpana kila kekahi o nā ʻano kila nui ʻehā (pā, paipu, ʻano, uea).Wahi a ke ʻano o ka ʻāpana, ua hoʻokaʻawale ʻia ka ʻāpana kila i ke kila ʻāpana maʻalahi a me ke kila ʻāpana paʻakikī (section steel).ʻO ka mea mua e pili ana i ke kila square, ke kila poepoe, ke kila pālahalaha, ke kila kihi, ke kila hexagonal, etc.;ʻO ka mea hope e pili ana i ka I-beam, ke kila awāwa, ke kila kila, ke kila pukaaniani, ke kila piko, etc.
Ke kila square - ʻāpana ʻāpana kila, ʻōwili wela a me ke anuanu;ka lōʻihi o ka ʻaoʻao ʻaoʻao kila 5-250mm;ʻO ka lōʻihi ʻaoʻao ʻaoʻao kila 3-100mm.
Ke kila poepoe - poepoe pauku o ke kila, maheleia i wela-owili, forged a me anu-kauo ekolu, wela-owili poepoe kila anawaena 5-250mm, o ka 5-9mm mea maʻamau hoʻohana 'ia e like me maka kumu no ke kaha kila uea, i kapaia uea koʻokoʻo. ;e like me ka hoʻolako ʻana i ka pā i kapa ʻia ʻo hot-rolled coil.ʻOi aku ka mānoanoa o ke kila poepoe i hoʻopaʻa ʻia, i hoʻohana ʻia e like me ka billet kumu.ʻO ke anawaena kila poepoe 3-100mm, pololei ka nui.
Ke kila angle - māhele ʻia i ʻelua ʻano like a me ke kila kihi ʻole.Hōʻike ʻia ka kikoʻī o ke kila kihi e ka nui o ka lōʻihi ʻaoʻao a me ka mānoanoa ʻaoʻao.ʻO ka maʻamau o nā kikoʻī o ke kila kihi i hana ʻia ʻo No. 2-20, ʻo ia ka helu o nā kenimika o ka lōʻihi ʻaoʻao.E like me No. 5 equilateral angle kila e pili ana i ka aoao lōʻihi o 5cm (50mm) huina kila.He 2-7 mau mānoanoa ʻaoʻao like ʻole ka helu like o nā kihi.
Keʻano helu kaumaha kila palahalaha
Paʻa kila: kaumaha no ka mika = 0.00785 * mānoanoa * ākea ʻaoʻao
