Mea wili pā lahilahiʻo ia ka ʻōwili (0.3 ~ 4.0) mm × (600 ~ 1000) mm ʻāpana ʻāpana ʻāpana ʻōwili.ʻO ka nui hāʻawi maʻamau o ka pepa wela wela i hoʻopau ʻia ʻo (0.5 ~ 2.0) × 1000 × 2000mm (mānoanoa × ākea × lōʻihi), i ʻōwili ʻia e ka papa kuhikuhi e pili ana me ka wili pepa 1200.Ma muli o ka hoʻomehana wela kiʻekiʻe o ka papa i ka multi-pass rolling.Ma hope o ka deformation nui, ʻaʻole pololei nā ʻaoʻao, no laila ua ʻoki ʻia nā ʻaoʻao ʻehā.I mea e hoʻokō ai i ka nui hāʻawi maʻamau, ʻo ka ʻōwili maoli e waiho i kahi palena kūpono.
ʻO ka maʻamau, ʻo ka nui o ka papa ʻōpala ma hope o ka ʻōwili ʻia ʻana ma kahi o 1040 × 2320mm (ākea × lōʻihi), a ʻo ka nui kūpono o 1000 × 2000mm e ʻoki ʻia e ka ʻāpana diski, ʻo ka shear rate (shear rate) o ka papa ʻōpala ma hope o ka ʻako ʻana: 1000 × 2000 / 1040 × 2320 = 82.89% ʻO ka poho i hana ʻia e ka ʻoki ʻoki a me ke poʻo a hiki i 17.11%, a lilo ia i ka bottleneck nui e hoʻomaikaʻi i ka helu.Hiki i ka hoʻohana ʻana i ke kaʻina hana pālua ʻelua ke hoʻohaʻahaʻa maikaʻi i ka pohō poʻo ʻoki.
ʻO ka loina lola
ʻO ke kumu kumu o ka ʻōwili pālua ʻelua ʻo ia ka loaʻa ʻana o ʻelua pūʻulu o nā huahana i hoʻopau ʻia ma hope o ka ʻako ʻana i ka lōʻihi o nā ʻaoʻao ʻelua o nā papa ʻōpala i ka manawa hoʻokahi.ʻO ka pōmaikaʻi, ʻo nā papa ʻelua o nā papa e pono e ʻoki i ʻelua mau poʻo a me nā huelo, ʻehā mau ʻāpana, ʻoiai ʻo ka ʻōnaehana ʻōwili pālua e pono e ʻoki i hoʻokahi poʻo a me nā huelo, ke hoʻohālikelike ʻia me ka hōʻemi ʻana o hoʻokahi set nā poʻo a me nā huelo, pēlā e hoʻomaikaʻi ai i ka hua.
Hiki ke helu ʻia ka nui o ka ʻako penei: (1000 × 2000) × 2 / 1040 × 4500 = 85.47%, no laila hiki ke ʻike ʻia ua hiki ke hoʻonui ʻia ka nui o ka ʻako e 2.58 mau helu pākēneka i hoʻohālikelike ʻia me ka ʻōwili pālua ma o ka hoʻohana ʻana i ka pālua. peʻa kaʻa.
Pūnaehana hoʻomehana
ʻAʻole pono e ʻoi aku ka nui o ke kaumaha ma mua o 35%, no ka mea, ʻo ka ʻōwili pālua ʻelua ma mua o ka ʻōwili pākahi hoʻokahi e hoʻonui pinepine ʻia i 2 a 3 mau manawa, e hopena i ka wahi wela a me ka manawa hoʻomaha wela, i mea e hōʻoia ai i ka wela o ka ʻōwili ʻana, ka puka ākea. Ua hoʻonui ʻia ka mahana o ka kikoʻī like ma mua o ka ʻōwili pākahi pākahi e 30 a 50 ℃.
