ʻŌwili Wela
ʻO ke kaula wili wela kahi mea kumu i ka ʻoihana kila. Hana ʻia ia ma o ke kaʻina hana wili wela kiʻekiʻe a he mau ʻano o ke kumukūʻai haʻahaʻa, ikaika kiʻekiʻe, a me ka hana hana maikaʻi. Hoʻohana nui ʻia ia i ke kūkulu ʻana, nā mīkini, nā kaʻa, ke kūkulu moku a me nā ʻoihana ʻē aʻe.
Ka wehewehe kumu
ʻO ka ʻōwili wela (HRC) e pili ana i nā huahana kila i ʻōwili mau ʻia ma luna o ka mahana recrystallization (maʻamau >900°C) e nā billets (e like me nā slabs a i ʻole billets) a laila ʻōwili ʻia.
ʻOkoʻa mai ka ʻōwili anu: ʻAʻole ʻōwili anu ka ʻōwili wela, ʻaʻole ʻōniʻoniʻo ka ʻili, haʻahaʻa ka pololei o ke ana, akā kiʻekiʻe ka ikaika a maikaʻi ka ductility, kūpono no ka hana ʻana i nā ʻāpana kūkulu.
Nā hiʻohiʻona nui
| Nā ʻano | ʻŌwili wela | ʻōwili anu |
| Kaʻina hana | Ka ʻōwili ʻana i ka mahana kiʻekiʻe (>900°C) | Ka ʻōwili mahana maʻamau (hana anu) |
| ʻAno o ka ʻili | ʻAʻole like ka unahi ʻokikene, ʻāwiliwili | Laumania, pololei kiʻekiʻe |
| Ikaika | Haʻahaʻa (akā maikaʻi ka paʻakikī) | Kiʻekiʻe (paʻakikī o ka hana) |
| Kumukūʻai | Haʻahaʻa | Kiʻekiʻe |
| Nā noi | Nā ʻāpana kūkulu, nā paipu, nā mōlina kaʻa | Nā ʻāpana kikoʻī, nā mīkini home, nā panela kaʻa |
3. Kaʻina hana
Hoʻomehana: Hoʻomehana ʻia ka ʻāpana kila i 1100 ~ 1250 ° C e palupalu ai.
ʻŌwili ʻino: Ke hana mua ʻana ma o kahi wili ʻōwili kiʻekiʻe.
Hoʻopau i ka ʻōwili ʻana: E kāohi i ka mānoanoa i ka nui i manaʻo ʻia (e like me 1.2 ~ 20mm).
Ka wili ʻana: Ma hope o ka ʻōwili ʻana, ua ʻōwili ʻia i loko o kahi wili kila (ʻo ka maʻamau he 1 ~ 2 mika ke anawaena o waho).
Hoʻomaʻalili: Hoʻomaʻalili kūlohelohe a i ʻole ka hoʻomaʻalili i kāohi ʻia (e like me ke kaʻina hana TMCP).
Nā kikoʻī maʻamau
Mānoanoa: 1.2~25mm (maʻamau 2.0~6.0mm).
Laulā: 600 ~ 2200mm (maʻamau 1250mm, 1500mm).
Mea Hana: Q235B (kila kalapona maʻemaʻe), SS400 (maʻamau Kepanī), A36 (maʻamau ʻAmelika), S355JR (maʻamau ʻEulopa).
Nā waiwai mechanical: ikaika tensile 300 ~ 500MPa, ikaika hua 200 ~ 400MPa.
Nā wahi noi nui
ʻOihana kūkulu hale: H-beam, ʻano kila, alahaka, ʻaukā kila.
Hana ʻana i nā mīkini: nā mīkini ʻenekinia, nā lako hana mining, ka ipu kaomi.
ʻOihana kaʻa: mōlina, kikowaena huila, ʻano chassis.
ʻOihana paipu: paipu i hoʻopaʻa ʻia, paipu ʻōwili (e like me ke kila paipu API 5L).
ʻOihana kūkulu moku: pā moku, kūkulu bulkhead.
Hoʻopili ka ʻoihana i kahi mea nui i ka maikaʻi o nā huahana, hoʻopukapuka nui i ka hoʻolauna ʻana i nā lako holomua a me nā poʻe loea, a hele i waho e hoʻokō i nā pono o nā mea kūʻai aku ma ka home a ma waho.
Hiki ke hoʻokaʻawale ʻia ka ʻike i loko o: ka haku mele kemika, ka ikaika hua, ka ikaika tensile, ka waiwai hopena, a pēlā aku
I ka manawa like, hiki i ka ʻoihana ke hana i ka ʻike ʻana i nā kīnā pūnaewele a me ka annealing a me nā kaʻina hana wela ʻē aʻe e like me nā pono o ka mea kūʻai aku.

ʻO Tianjin YuantaiDerun Steel Tube Manufacturing Group Co., Ltd.he hale hana paipu kila i hōʻoia ʻia eEN/ASTM/ JIShana kūikawā ana i ka hana ʻana a me ka hoʻokuʻu aku i nā ʻano paipu huinahā like ʻole, paipu galvanized, paipu welded ERW, paipu wili, paipu welded arc i hoʻopaʻa ʻia, paipu humuhumu pololei, paipu humuhumu ʻole, wili kila i uhi ʻia i ke kala, wili kila galvanized a me nā huahana kila ʻē aʻe. Me ka halihali kūpono, he 190 kilomita ka mamao mai ke kahua mokulele ʻo Beijing Capital International a me 80 kilomita ka mamao mai Tianjin Xingang.
