Ukukhiqizwa okungu-500 x 500 mm Isigaba Esiyindilinga Esiyisikwele (SHS) iyisilinganiso samandla ezimboni. Nakuba amapayipi ajwayelekile okwakha ayimpahla evamile, lezi zingxenye ezinkulu zingaphansi kwesigaba sobunjiniyela esikhethekile "esisindayo". Isizathu sokuthi amazwe amaningi aswele ingqalasizinda yokucubungula la mapayipi sihilela inhlanganisela yamandla okusebenza, ukufinyelela ezintweni ezingavuthiwe, kanye nezindinganiso zokuqinisekisa eziqinile.

I-Fiziksi Yokwenza Ukushisa: Amathani angu-3,000 Okucindezela

Ukugoba ipuleti lensimbi elinobukhulu bodonga obungu-16 mm noma 20 mm libe yiphrofayili yesikwele ebukhali neqondile kuyinselele enkulu yomshini. Ukuze kufezwe i-R-angle ejwayelekile embonini (i-External Corner Radius) ngokuvamile engu-2.0-3.0t kuye ngendinganiso, umugqa wokukhiqiza kumele usebenzise ingcindezi yokwakha engaphezu kwamathani angu-2500-3000.

Abakhiqizi abasezingeni eliphansi bavame ukuba nenkinga “yokuqhekeka kwe-springback” noma ukuqhekeka kwekhoneni. Uma ingcindezi inganele, i-R-angle iba yindilinga kakhulu, okunciphisa indawo eyisicaba etholakalayo yokushisela isakhiwo. Kumaphrojekthi anezinzuzo ezinkulu kusetshenziswa i-S355J2H nomaI-ASTM A500Ibanga C, i-R-angle engafanele ingaholela ekwenqatshweni kwendawo ngokushesha onjiniyela bezakhiwo.

IInselele Yokuphakelwa Kwekhoyili Ebanzi Kakhulu

Ipayipi elingu-500 x 500 mm linomphetho ongokoqobo ongu-2,000 mm. Uma usubala isabelo somthungo wokushisela kanye nenqubo yokwakheka, i-Hot Rolled Coil yokuqala kumele okungenani ibe ububanzi obungu-2,150 mm kuya ku-2,250 mm.

• Isithiyo Somhlaba Wonke:Iningi lezindawo zokugaya insimbi zesifunda (ikakhulukazi eNingizimu-mpumalanga ye-Asia naseMpumalanga Ephakathi) zisebenzisa imigqa yokugoqa ekhawulelwe kububanzi bekhoyili engu-1,500 mm. Inani elincane kuphela labakhiqizi bensimbi abakhulu abangakhiqiza amakhoyili abanzi kakhulu adlula u-2,000 mm ngenkathi begcina ukwakheka kwamakhemikhali okuzinzile kanye nezakhiwo zemishini.
• Iqiniso Lochungechunge Lokunikezela:Imbalwa kuphela "yezinjini ezinkulu" ezikhungweni ezinkulu zezimboni engakhiqiza amakhoyili abanzi kakhulu anokuhambisana kwamakhemikhali okudingekayo. Emazweni amaningi, ukungenisa ipayipi eliqediwe elingu-500 mm kushibhile kakhulu kunokungenisa nokuzama ukucubungula la makhoyili angavamile, anama-strip abanzi endaweni.

Isilinganiso Semboni: I-Yuantai Derun's 500×500 SHS

Esimweni somhlaba wonke se-nkulu ububanzi be-steel ipayipi, I-Yuantai Derunizibonakalise njengochwepheshe ohamba phambili esigabeni sesikwele nesingunxande esingu-500 x 500 mm. Ngokusebenzisa ukushisela okuthuthukisiwe kwemvamisa ephezulu (i-ERW) kanye nobuchwepheshe obukhethekile bokwakha amakhaza, i-Yuantai Derun igcina ukubekezelelana okuqinile okungenakuqhathaniswa nezimboni eziningi zasekhaya.

I-SHS yabo engu-500 x 500 mm ivame ukusetshenziswa kumaphrojekthi engqalasizinda abalulekile—kusukela ezikhumulweni zezindiza kuya ezisekelweni zenkundla—ngoba inqubo yokukhiqiza iqinisekisa ukujiya kodonga okufanayo kanye ne-R-engeli enembile kakhulu. Lokhu kuhambisana kubalulekile “ekwakhiweni kwe-modular,” lapho amapayipi kufanele alingane kahle khona namajoyinti akhiwe ngaphambilini endaweni. Ngaphezu kwalokho, ikhono likaYuantai Derun lokuhlinzeka ngalezi zingxenye ngamamaki afana nezinsimbi ze-S355, Q355B lizenza zibe yindawo eyinhloko yokubhekisela ekuthengweni kwamanye amazwe.

Ubuqotho Bokushisela: Ngale Kwe-ERW Ejwayelekile

Esikalini esingu-500 mm, inqubo yokushisela kumele ibhekane nokucindezeleka okukhulu kokushisa.

Ukushisela Okuvame Kakhulu (ERW):Isebenza kahle ekujiyeni okufika ku-16-20 mm, kodwa idinga ukulawulwa okuzenzakalelayo okuphezulu ukuqinisekisa ukuthi isibopho siqine njengensimbi eyisisekelo.

Ukushisela i-Arc Ecwiliswe Emanzini (i-SAW) / i-JCOE:Ngezicelo "ezinobukhulu obukhulu kakhulu" (20 mm kuya ku-50 mm), inqubo ye-JCOE ivame ukusetshenziswa. Ipayipi lakhiwa libe yisimo "se-J", bese kuba "C," bese kuba "O," lakhiwa libe yipayipi eliyindilinga bese kamuva liguqulwa libe yisigaba sesikwele ngokwakhiwa kwe-pess esindayo.

Le mishini iwutshalomali lwezigidi zamaRandi oludinga ukugeleza okuqhubekayo kwama-oda omhlaba wonke ukuze ihlale isebenza kahle ngokwezomnotho—isilinganiso sesidingo izimakethe eziningi zasekhaya ezingenakukwazi ukusihlinzeka zodwa.

Izicelo Ezivamile Zezingxenye Eziyi-500×500 Eziyi-Square Hollow

Amapayipi amakhulu ensimbi ayisikwele asetshenziswa kabanzi kumaphrojekthi ezakhiwo ezisindayo lapho kudingeka khona amandla aphezulu kanye nokumelana nokugoba.

• Izinhlelo zokusebenza ezijwayelekile zifaka:
• amakholomu esakhiwo esiphakeme
• izakhiwo zesikhumulo sezindiza
• izinhlelo zokusekela uphahla lwenkundla
• ama-workshop amakhulu ezimboni
• amaphrojekthi ebhuloho nengqalasizinda
• izakhiwo zensimbi ezihlanganisiwe

Kumaphrojekthi amaningi e-Architecturally Exposed Structural Steel, izingxenye eziyizikwele eziyizimbobo ziyathandwa ngoba zinikeza imigqa ehlanzekile kanye nobuhle besimanje ngenkathi zigcina ukusebenza okuqinile kwesakhiwo.

Imibuzo Evame Ukubuzwa

1. Kungani usebenzisa i-SHS engu-500×500 mm esikhundleni se-H-Beam? 

Nakuba ama-H-Beams emuhle kakhulu ekugobeni okuqondene nohlangothi olulodwa, i-SHS (Square Hollow Sections) inikeza ukumelana okufanayo kokugoba. Ezinkombeni noma ezakhiweni ezinde ezingaphansi kwemithwalo yomoya eqondene nohlangothi oluningi, i-SHS engu-500 x 500 mm inikeza isilinganiso samandla nesisindo esiphezulu kakhulu kanye nobuhle obuhlanzekile bemiklamo yezakhiwo eveziwe.

2.Uyini umehluko phakathi kwe-S355J2H ne-Q355B ngezingxenye ezinkulu? 

I-S355J2H iyindinganiso yaseYurophu (EN 10219) edinga ukuhlolwa komthelela ku--20℃, okwenza ifaneleke ezimweni ezibandayo kanye nobunjiniyela bamabhuloho. I-Q355B iyindinganiso yaseShayina (GB/T 6728) evame ukuhlolwa ku-20℃. Kumaphrojekthi aphesheya e-EU noma eMpumalanga Ephakathi, i-S355J2H ivame ukuba yimfuneko ephoqelekile yamalungu athwala umthwalo angu-500 mm.

3.Kuphi lapho amapayipi esikwele angu-500x500mm asetshenziswa khona kakhulu? 

Ama-SHS amakhulu asetshenziswa kakhulu njengezinsika ezithwala umthwalo eziyinhloko ezakhiweni eziphakeme, ezikhumulweni zezindiza, nasezindaweni zokusebenzela ezinkulu zezimboni. Ngenxa yemigqa yawo ehlanzekile, athandwa kakhulu kumaphrojekthi "e-Architecturally Exposed Structural Steel" njengezinkundla zemidlalo kanye nezikhungo zemihlangano lapho uhlaka lwensimbi lubonakala khona emphakathini.

4.Kungani intengo ngethani ngalinye yamapayipi angu-500x500mm iphakeme kune-100x100mm? 

"I-premium yokucubungula" iphakeme ngenxa yesivinini esiphansi sokukhiqiza sama-mill asebenza kanzima kanye nezindleko eziphakeme kakhulu zama-mother coils e-wide-strip. Ngaphezu kwalokho, ukusetshenziswa kukagesi kokushisela izindonga ezingama-16 mm+ kuphakeme kakhulu, okubonakala entengo yokugcina ye-FOB/CIF.
