ʻO ka hana ʻana o 500 x 500 mm ʻĀpana hakahaka huinahā ʻO (SHS) kahi pae hoʻohālikelike o ka hiki ke ʻoihana. ʻOiai he waiwai maʻamau ka paipu kūkulu maʻamau, pili kēia mau ʻāpana nui i kahi papa ʻenekinia "kaumaha" kūikawā. ʻO ke kumu i nele ai nā ʻāina he nui i ke kahua e hana ai i kēia mau paipu e pili ana i ka hui pū ʻana o ka ikaika mechanical, ke komo ʻana i nā mea maka, a me nā kūlana hōʻoia koʻikoʻi.

ʻO ke Kino o ke Anuanu: 3,000 Tons o ke Kaomi

ʻO ke kulou ʻana i kahi papa kila me ka mānoanoa o ka paia he 16 mm a i ʻole 20 mm i loko o kahi ʻaoʻao huinaha ʻoi a pololei hoʻi he pilikia nui ia no ka mīkini. No ka hoʻokō ʻana i ke kūlana R-angle (External Corner Radius) maʻamau he 2.0-3.0t ma muli o ke kūlana, pono i kahi laina hana ke hoʻoikaika ma mua o 2500-3000 tons o ke kaomi hana.

Hoʻopilikia pinepine nā mea hana haʻahaʻa me ka "springback" a i ʻole ka haki kihi. Inā lawa ʻole ke kaomi, lilo ka R-angle i poepoe loa, e hōʻemi ana i ka ʻāpana ʻili pālahalaha i loaʻa no ka hoʻopili ʻana i ke kūkulu ʻana. I nā papahana kiʻekiʻe e hoʻohana ana iā S355J2H a i ʻoleASTM A500Papa C, hiki i kahi kihi-R kūpono ʻole ke alakaʻi koke i ka hōʻole ʻia ʻana o ka pae e nā ʻenekinia kūkulu.

ʻO kaKa Hoʻokūkū Hoʻolako ʻUlula-Wide Coil

ʻO ka palena kino o ka paipu 500 x 500 mm he 2,000 mm. Ke helu ʻoe i ka ʻae ʻia o ke kāwili wili a me ke kaʻina hana, pono ka laulā o ka Wela Rolled Coil hoʻomaka ma ka liʻiliʻi he 2,150 mm a i 2,250 mm.

• Ka Palena Honua:ʻO ka hapa nui o nā hale wili kila ʻāpana (ʻoi aku hoʻi ma Asia Hikina Hema a me ka Hikina Waena) e hana i nā laina ʻōwili i kaupalena ʻia i ka laulā o ka coil 1,500 mm. He helu liʻiliʻi wale nō o nā mea hana kila nui e hiki ke hana i nā coil ultra-wide ma mua o 2,000 mm me ka mālama ʻana i ka haku mele kemika paʻa a me nā waiwai mechanical.
• ʻO ka ʻoiaʻiʻo o ke kaulahao lako:He kakaikahi wale nō o nā "super-mills" ma nā kikowaena ʻoihana nui e hiki ke hana i nā wili ultra-ākea me ke kūlike kemika e pono ai. No nā ʻāina he nui, ʻoi aku ka liʻiliʻi o ke kumukūʻai o ka lawe ʻana mai i ka paipu 500 mm i hoʻopau ʻia ma mua o ka lawe ʻana mai a me ka hoʻāʻo ʻana e hana i kēia mau wili laulā laha ʻole ma kahi kūloko.

Ka Hoʻohālikelike ʻOihana: Yuantai Derun's 500 × 500 SHS

Ma ke ʻano honua onui ke anawaena steel paipu, Yuantai Derunua hoʻokumu iā ia iho ma ke ʻano he loea alakaʻi i ka māhele 500 x 500 mm square a me rectangular. Ma ka hoʻohana ʻana i ka hoʻoheheʻe alapine kiʻekiʻe (ERW) a me ka ʻenehana hoʻokumu anu kūikawā, mālama ʻo Yuantai Derun i nā hoʻomanawanui paʻa i hiki ʻole i nā hale hana kūloko he nui ke hoʻokūkū.

Hoʻohana pinepine ʻia kā lākou 500 x 500 mm SHS i nā papahana ʻoihana koʻikoʻi—mai nā kikowaena mokulele a hiki i nā kākoʻo kahua pāʻani—no ka mea, ʻo ke kaʻina hana e hōʻoiaʻiʻo ana i ka mānoanoa like o ka paia a me kahi kihi R pololei loa. He mea nui kēia kūlike no ka "kūkulu modular," kahi e pono ai nā paipu e kūpono i nā hui i hana mua ʻia ma kahi. Eia kekahi, ʻo ka hiki iā Yuantai Derun ke hoʻolako i kēia mau ʻāpana ma nā papa e like me S355, Q355B steels e hoʻolilo iā lākou i kumu kuhikuhi mua no ke kūʻai ʻana o ka honua.

Kuʻuna Kuʻihao: Ma ʻō aku o ke kūlana ERW

Ma ka pae 500 mm, pono ke kaʻina hana kuʻihao e hoʻoponopono i nā pilikia wela koʻikoʻi.

Kuʻihao Alapine Kiʻekiʻe (ERW):Kūpono no nā mānoanoa a hiki i 16-20 mm, akā koi ʻia ka mana hana kiʻekiʻe e hōʻoia i ka ikaika o ka pilina e like me ke metala kumu.

Kuʻihao Arc i hoʻoheheʻe ʻia (SAW) / JCOE:No nā noi "mānoanoa loa" (20 mm a 50 mm), hoʻohana pinepine ʻia ke kaʻina hana JCOE. Hoʻokumu ʻia ka paipu i ke ʻano "J", a laila "C," a laila "O," hoʻokumu ʻia i paipu poepoe a ma hope hoʻi hoʻololi hou ʻia i ʻāpana huinahā ma o ka hana ʻana i nā pess kaumaha.

He hoʻopukapuka kālā miliona miliona kēia lako e pono ai ke kahe mau o nā kauoha honua e noho kūpono ai i ka hoʻokele waiwai—he nui o ke koi i hiki ʻole i ka hapa nui o nā mākeke kūloko ke hoʻolako ma o lākou iho.

Nā Hoʻohana Maʻamau o nā ʻĀpana Hollow Square 500 × 500

Hoʻohana nui ʻia nā paipu kila huinahā nui i nā papahana kūkulu kaumaha kahi e pono ai ka ikaika kiʻekiʻe a me ke kū'ē torsional.

• ʻO nā noi maʻamau e komo pū me:
• nā kolamu hale kiʻekiʻe
• nā hale kikowaena mokulele
• nā ʻōnaehana kākoʻo o ka hale o ke kahua pāʻani
• nā hale hana ʻoihana nui
• nā papahana alahaka a me nā ʻoihana kūkulu hale
• nā hale kila modular

I loko o nā papahana kila kila i hōʻike ʻia ma ke ʻano he nui, makemake ʻia nā ʻāpana hakahaka huinahā no ka mea hāʻawi lākou i nā laina maʻemaʻe a me nā aesthetics hou me ka mālama ʻana i ka hana kūkulu ikaika.

Nā nīnau i nīnau pinepine ʻia

1. No ke aha e hoʻohana ai i kahi SHS 500 × 500 mm ma kahi o kahi H-Beam? 

ʻOiai he maikaʻi loa nā H-Beams no ke kūlou ʻana i hoʻokahi ʻaoʻao, hāʻawi ʻo SHS (Square Hollow Sections) i ke kū'ē torsional like. I nā kolamu kihi kiʻekiʻe a i ʻole nā ​​​​hale i kau ʻia i nā ukana makani multi-directional, hāʻawi ka 500 x500 mm SHS i kahi lakio ikaika-a-kaumaha kiʻekiʻe loa a me kahi aesthetic maʻemaʻe no nā hoʻolālā kuhikuhipuʻuone i hōʻike ʻia.

2He aha ka ʻokoʻa ma waena o S355J2H a me Q355B no nā ʻāpana nui? 

He kūlana ʻEulopa ʻo S355J2H (EN 10219) e koi ana i ka hoʻāʻo hopena ma -20 ℃, e kūpono ai no nā aniau anuanu a me ka ʻenekinia alahaka. ʻO Q355B ke kūlana Kina (GB/T 6728) i hoʻāʻo pinepine ʻia ma 20 ℃. No nā papahana honua ma ka EU a i ʻole ka Hikina Waena, ʻo S355J2H pinepine ke koi koi no nā lālā lawe ukana 500 mm.

3.ʻAuhea nā paipu huinaha 500x500mm i hoʻohana pinepine ʻia? 

Hoʻohana nui ʻia nā SHS nui ma ke ʻano he mau kolamu amo nui i nā hale kiʻekiʻe, nā kikowaena mokulele, a me nā hale hana ʻoihana nui. Ma muli o ko lākou mau laina maʻemaʻe, he punahele nō hoʻi lākou i nā papahana "Architecturally Exposed Structural Steel" e like me nā kahua pāʻani a me nā kikowaena hālāwai kahi e ʻike ʻia ai ke kiʻi kila e ka lehulehu.

4.No ke aha i ʻoi aku ai ke kumukūʻai no kēlā me kēia tona no nā paipu 500x500mm ma mua o 100x100mm? 

ʻOi aku ke kiʻekiʻe o ka "uku hana" ma muli o ka wikiwiki hana haʻahaʻa o nā wili kaumaha a me ke kumukūʻai kiʻekiʻe loa o nā wili makuahine ākea. Eia kekahi, ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka uila no ka hoʻopili ʻana i ke alapine kiʻekiʻe o nā paia 16 mm+, kahi i hōʻike ʻia ma ke kumukūʻai hope loa o FOB/CIF.
