Kupanga kwa 500 x 500 mm Gawo Lopanda Mphepo (SHS) ndi muyezo wa luso la mafakitale. Ngakhale kuti mapaipi okhazikika ndi chinthu chofala, magawo akuluakuluwa ndi a gulu laukadaulo lapadera la "olemera kwambiri". Chifukwa chomwe mayiko ambiri alibe zomangamanga zogwirira ntchito pokonza mapaipi awa ndi kuphatikiza mphamvu yamakina, mwayi wopeza zinthu zopangira, ndi miyezo yokhwima ya satifiketi.

Fiziki ya Kupanga Zinthu Zozizira: Matani 3,000 a Kupanikizika

Kupinda mbale yachitsulo yokhala ndi khoma lolimba la 16 mm kapena 20 mm kukhala malo ozungulira olunjika bwino ndi vuto lalikulu la makina. Kuti mukwaniritse R-angle yokhazikika (External Corner Radius) yomwe nthawi zambiri imakhala 2.0-3.0t kutengera muyezo, mzere wopanga uyenera kugwiritsa ntchito mphamvu yoposa matani 2500-3000.

Opanga makina otsika nthawi zambiri amavutika ndi "kusweka kwa ma springback" kapena kusweka kwa ngodya. Ngati kupanikizika sikukwanira, ngodya ya R imakhala yozungulira kwambiri, zomwe zimachepetsa malo athyathyathya omwe alipo kuti agwiritsidwe ntchito powotcherera. Mu mapulojekiti akuluakulu pogwiritsa ntchito S355J2H kapenaASTM A500Giredi C, R-angle yolakwika ingayambitse kukanidwa kwa malo nthawi yomweyo ndi mainjiniya omanga.

TheVuto Lopereka Ma Coil Ochuluka Kwambiri

Chitoliro cha 500 x 500 mm chili ndi m'lifupi mwake wa 2,000 mm. Mukangoganizira za njira yolumikizirana ndi njira yopangira, Hot Rolled Coil yoyambira iyenera kukhala ndi mulifupi wa 2,150 mm mpaka 2,250 mm.

• Choletsa Padziko Lonse:Makampani ambiri opanga zitsulo m'madera osiyanasiyana (makamaka ku Southeast Asia ndi Middle East) amagwiritsa ntchito mizere yozungulira yomwe ili ndi m'lifupi wa coil wa 1,500 mm. Ndi opanga ochepa okha achitsulo omwe amatha kupanga coils zazikulu kwambiri zopitilira 2,000 mm pomwe akusunga kapangidwe ka mankhwala kokhazikika komanso mphamvu zamakanika.
• Zoona za Unyolo Wopereka:Ma "super-mills" ochepa okha m'mafakitale akuluakulu ndi omwe angapange ma coil otakata kwambiri okhala ndi kusinthasintha kofunikira kwa mankhwala. Kwa mayiko ambiri, kuitanitsa chitoliro chomalizidwa cha 500 mm ndikotsika mtengo kwambiri kuposa kuitanitsa ndikuyesera kukonza ma coil osowa, otakata awa m'deralo.

Chizindikiro cha Makampani: Yuantai Derun's 500×500 SHS

Mu dziko lonse lapansi lachachikulu m'mimba mwakeeel chitoliro, Yuantai DerunYadzikhazikitsa ngati katswiri wotsogola mu gulu la 500 x 500 mm lalikulu ndi lamakona anayi. Pogwiritsa ntchito makina apamwamba olumikizirana ndi mafunde (ERW) komanso ukadaulo wapadera wopanga zinthu zozizira, Yuantai Derun amasunga kulekerera kokhwima komwe mafakitale ambiri am'nyumba sangagwirizane nako.

SHS yawo ya 500 x 500 mm imagwiritsidwa ntchito nthawi zambiri m'mapulojekiti odziwika bwino—kuyambira pa malo oimikapo magalimoto a eyapoti mpaka pothandizira mabwalo amasewera—chifukwa njira yopangira imatsimikizira makulidwe ofanana a khoma komanso ngodya yolondola kwambiri ya R. Kugwirizana kumeneku ndikofunikira kwambiri pa "mapulani omangira modular," komwe mapaipi ayenera kulowa bwino m'malo olumikizirana omwe adapangidwa kale pamalopo. Kuphatikiza apo, kuthekera kwa Yuantai Derun kupereka magawo awa m'magawo monga zitsulo za S355, Q355B kumawapangitsa kukhala malo ofunikira kwambiri pogula zinthu padziko lonse lapansi.

Umphumphu wa Kuwotcherera: Kupitilira Muyeso wa ERW

Pa sikelo ya 500 mm, njira yowotcherera iyenera kuthana ndi kutentha kwambiri.

Kuwotcherera kwa Ma Frequency Ambiri (ERW):Yogwira ntchito bwino pa makulidwe mpaka 16-20 mm, koma imafuna kulamulira kwapamwamba kwambiri kuti iwonetsetse kuti chomangiracho chili cholimba ngati chitsulo choyambira.

Kuwotcherera kwa Arc Yoviikidwa M'madzi (SAW) / JCOE:Pa ntchito "zokhuthala kwambiri" (20 mm mpaka 50 mm), njira ya JCOE nthawi zambiri imagwiritsidwa ntchito. Chitolirocho chimapangidwa kukhala mawonekedwe a "J", kenako "C," kenako "O," chimapangidwa kukhala chitoliro chozungulira kenako nkusinthidwa kukhala gawo lalikulu kudzera mukupanga mafinya olemera.

Zipangizozi ndi ndalama zambiri zomwe zimafuna ndalama zambiri zomwe zimafunika kuti zinthu zizigwiritsidwa ntchito padziko lonse lapansi kuti zikhalebe ndi phindu pazachuma—chinthu chomwe misika yambiri yakunyumba singathe kupereka yokha.

Kugwiritsa Ntchito Kawirikawiri kwa Magawo a 500 × 500 Square Hollow

Mapaipi akuluakulu achitsulo amagwiritsidwa ntchito kwambiri m'mapulojekiti olemera a zomangamanga komwe kumafunika mphamvu zambiri komanso kukana kugwedezeka.

• Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:
• zipilala zazitali za nyumba
• nyumba zomangira ndege
• makina othandizira denga la bwalo lamasewera
• malo ochitira misonkhano ikuluikulu yamakampani
• mapulojekiti a milatho ndi zomangamanga
• nyumba zachitsulo zokhazikika

Mu mapulojekiti ambiri a Architecturally Exposed Structural Steel, zigawo za malo ozungulira ndi malo otseguka zimakondedwa chifukwa zimapereka mizere yoyera komanso kukongola kwamakono pomwe zimasunga magwiridwe antchito amphamvu.

FAQ

1. N’chifukwa chiyani mugwiritse ntchito 500×500 mm SHS m’malo mwa H-Beam? 

Ngakhale kuti ma H-Beams ndi abwino kwambiri popindika mbali imodzi, SHS (Square Hollow Sections) imapereka kukana kofanana kwa torsional. Mu mizati yayitali kapena nyumba zomwe zimayendetsedwa ndi mphepo ya mbali zambiri, SHS ya 500 x 500 mm imapereka chiŵerengero champhamvu kwambiri poyerekeza ndi kulemera komanso kukongola koyera kwa mapangidwe owonekera.

2Kodi pali kusiyana kotani pakati pa S355J2H ndi Q355B pazigawo zazikulu? 

S355J2H ndi muyezo wa ku Europe (EN 10219) womwe umafuna mayeso a mphamvu pa -20℃, zomwe zimapangitsa kuti ikhale yoyenera nyengo yozizira komanso mainjiniya a mlatho. Q355B ndi muyezo waku China (GB/T 6728) womwe nthawi zambiri umayesedwa pa 20℃. Pa mapulojekiti apadziko lonse ku EU kapena Middle East, S355J2H nthawi zambiri imakhala chofunikira kwa mamembala onyamula katundu a 500 mm.

3.Kodi mapaipi a sikweya a 500x500mm amagwiritsidwa ntchito kwambiri kuti? 

Ma SHS akuluakulu amagwiritsidwa ntchito makamaka ngati zipilala zonyamula katundu m'nyumba zazitali, malo okwerera ndege, ndi malo akuluakulu ogwirira ntchito zamafakitale. Chifukwa cha mizere yawo yoyera, ndi omwe amakondedwa kwambiri mu mapulojekiti a "Architecturally Exposed Structural Steel" monga mabwalo amasewera ndi malo ochitira misonkhano komwe chimango chachitsulo chimawonekera kwa anthu onse.

4.N’chifukwa chiyani mtengo pa tani imodzi wa mapaipi a 500x500mm ndi wapamwamba kuposa 100x100mm? 

"Kukonza zinthu zapamwamba" kuli kokwera chifukwa cha liwiro lochepa la kupanga kwa mphero zolemera komanso mtengo wokwera kwambiri wa ma coil ang'onoang'ono. Kuphatikiza apo, magetsi omwe amagwiritsidwa ntchito powotcherera makoma a 16 mm+ pafupipafupi ndi okwera kwambiri, zomwe zimawonekera pamtengo womaliza wa FOB/CIF.
