Imveliso ye-500 x 500 mm Icandelo Elingenanto Elisikwere (SHS) luphawu lobuchule bemizi-mveliso. Nangona iityhubhu ezisemgangathweni zesakhiwo ziyimpahla eqhelekileyo, ezi candelo zinkulu zikwiklasi ekhethekileyo yobunjineli "obunzima". Isizathu sokuba amazwe amaninzi angabi naziseko zophuhliso zokucubungula ezi payipi sibandakanya indibaniselwano yamandla oomatshini, ukufikelela kwizinto eziluhlaza, kunye nemigangatho yoqinisekiso oluqinileyo.

Ifiziksi Yokwenza Ubushushu: Iitoni Eziyi-3,000 Zoxinzelelo

Ukugoba ipleyiti yentsimbi enobukhulu bodonga obuyi-16 mm okanye i-20 mm kwiprofayili yesikwere ebukhali nechanekileyo ngumceli mngeni omkhulu woomatshini. Ukufezekisa i-R-angle esemgangathweni weshishini (i-External Corner Radius) edla ngokuba yi-2.0-3.0t kuxhomekeke kumgangatho, umgca wokuvelisa kufuneka usebenzise uxinzelelo olungaphezulu kweetoni ezingama-2500-3000.

Abavelisi abakumgangatho ophantsi badla ngokuba neengxaki "zokubuyela umva" okanye ukuqhekeka kwekona. Ukuba uxinzelelo alwanelanga, i-R-angle iba yingqukuva kakhulu, nto leyo enciphisa indawo ethe tyaba ekhoyo yokuwelda kwesakhiwo. Kwiiprojekthi ezixabisa kakhulu kusetyenziswa i-S355J2H okanyeI-ASTM A500Ibanga C, i-R-angle engafanelekanga inokukhokelela ekungavunywa kwangoko kwendawo ziinjineli zezakhiwo.

IUmngeni woNikezelo lweeKhoyili eziBanzi kakhulu

Umbhobho we-500 x 500 mm unomda obonakalayo we-2,000 mm. Wakuba uchaze isibonelelo somthungo we-weld kunye nenkqubo yokuyila, i-Hot Rolled Coil yokuqala kufuneka ibe nobubanzi obuyi-2,150 mm ukuya kwi-2,250 mm.

• Umqobo weHlabathi:Uninzi lweefektri zentsimbi zengingqi (ingakumbi eMzantsi-mpuma Asia naseMbindi Mpuma) zisebenzisa imigca yokuqengqeleka elinganiselwe kububanzi bekhoyili eyi-1,500 mm. Linani elincinci kuphela labavelisi abakhulu bentsimbi abanokuvelisa iikhoyili ezibanzi kakhulu ezidlula i-2,000 mm ngelixa begcina ukwakheka kweekhemikhali okuzinzileyo kunye neempawu zoomatshini.
• Inyani yeCandelo loNikezelo:Zimbalwa kuphela "ii-super-mills" kwiindawo ezinkulu zoshishino ezinokuvelisa ii-coils ezibanzi kakhulu ezinobungqingqwa beekhemikhali obufunekayo. Kumazwe amaninzi, ukungenisa umbhobho ogqityiweyo we-500 mm kubiza kakhulu kunokungenisa nokuzama ukucubungula ezi coils zinqabileyo, ezibanzi apha ekhaya.

Uphawu lweShishini: I-Yuantai Derun's 500×500 SHS

Kwimeko yehlabathi jikelelenkulu ububanzi be-steel umbhobho, Yuantai DerunIzakhele igama njengengcali ephambili kudidi lwesikwere nolwengxande oluyi-500 x 500 mm. Ngokusebenzisa i-welding ephezulu ephindaphindayo (ERW) kunye netekhnoloji ekhethekileyo yokwenza ubushushu, iYuantai Derun igcina ukunyamezelana okungqongqo okungenakufikelelwa ziifektri ezininzi zasekhaya.

I-SHS yabo engama-500 x 500 mm isetyenziswa rhoqo kwiiprojekthi zeziseko zophuhliso ezibalulekileyo—ukusuka kwizitishi zeenqwelo moya ukuya kwizixhaso zenkundla—kuba inkqubo yemveliso iqinisekisa ubukhulu bodonga obufanayo kunye ne-R-engile echanekileyo kakhulu. Olu lungelelwaniso lubalulekile “kulwakhiwo lwemodyuli,” apho imibhobho kufuneka ilingane ngokugqibeleleyo kwiindawo ezidityanisiweyo esele zenziwe kwindawo. Ngaphezu koko, amandla kaYuantai Derun okubonelela la macandelo kwiindidi ezifana neentsimbi ze-S355, Q355B azenza zibe yindawo ephambili yokujonga ukuthengwa kwamanye amazwe.

Ukunyaniseka kweWelding: Ngaphaya kwe-ERW esemgangathweni

Kwisikali se-500 mm, inkqubo yokudibanisa kufuneka ijongane noxinzelelo oluphezulu lobushushu.

Ukuwelda Okuphindaphindwayo (ERW):Isebenza kakuhle kwiingqiniba ezifikelela kwi-16-20 mm, kodwa ifuna ulawulo oluzenzekelayo oluphezulu ukuqinisekisa ukuba i-bond iqinile njenge-base metal.

Ukuwelda kwe-Arc efakwe emanzini (i-SAW) / i-JCOE:Kwizicelo "ezinobukhulu obugqithisileyo" (20 mm ukuya kwi-50 mm), inkqubo ye-JCOE idla ngokusetyenziswa. Umbhobho wenziwa ube yimo "J", uze ube "C," uze ube "O," wenziwe ube yipayipi engqukuva uze kamva uguqulwe ube yicandelo lesikwere ngokusebenzisa ukwakheka kwe-pess enzima.

Esi sixhobo sityalo-mali oluxabisa izigidi zeerandi olufuna uthotho oluqhubekayo lwee-odolo zehlabathi ukuze zihlale zisebenza kakuhle ngokwezoqoqosho—umlinganiselo wemfuno uninzi lweemarike zasekhaya olungenakukwazi ukuyibonelela zodwa.

FAQ

1. Kutheni usebenzisa i-500×500 mm SHS endaweni ye-H-Beam? 

Nangona ii-H-Beams zilungile kakhulu ekugobeni kwicala elinye, i-SHS (iiSquare Hollow Sections) zibonelela ngokumelana okufanayo kokujika. Kwiikholamu eziphakamileyo okanye izakhiwo ezikwikona eziphantsi kwemithwalo yomoya ekhokelela kwicala elinye, i-500 x 500 mm SHS inika umlinganiselo ophezulu kakhulu wamandla nobunzima kunye nobuhle obucocekileyo kwiindlela zoyilo lwezakhiwo eziveziweyo.

2.Yintoni umahluko phakathi kwe-S355J2H kunye ne-Q355B kwiindawo ezinkulu? 

I-S355J2H ngumgangatho waseYurophu (EN 10219) ofuna uvavanyo lwempembelelo kwi -20℃, nto leyo eyenza ukuba ifaneleke kwiimeko ezibandayo kunye nobunjineli beebhulorho. I-Q355B ngumgangatho waseTshayina (GB/T 6728) ovavanywa rhoqo kwi-20℃. Kwiiprojekthi zamazwe ngamazwe kwi-EU okanye kuMbindi Mpuma, i-S355J2H idla ngokuba yimfuneko enyanzelekileyo kumalungu athwala umthwalo angama-500 mm.

3.Ziphi iipayipi zesikwere ezingama-500x500mm ezisetyenziswa kakhulu? 

Ii-SHS ezinkulu zisetyenziswa kakhulu njengeentsika eziphambili ezithwala umthwalo kwizakhiwo eziphakamileyo, kwiindawo zokubeka izikhululo zeenqwelo moya, nakwiindawo zokusebenzela ezinkulu zoshishino. Ngenxa yemigca yazo ecocekileyo, zikwathandwa kakhulu kwiiprojekthi ze-"Architecturally Exposed Structural Steel" ezifana neenkundla zemidlalo kunye neendawo zendibano apho isakhelo sentsimbi sibonakala khona kuluntu.

4.Kutheni ixabiso ngetoni nganye leepayipi ezingama-500x500mm liphezulu kune-100x100mm? 

"I-premium yokucubungula" iphezulu ngenxa yesantya esiphantsi semveliso yee-mills ezisebenza nzima kunye nexabiso eliphezulu kakhulu lee-wide-strip mother coils. Ukongeza, ukusetyenziswa kombane kwi-high-frequency welding yeendonga ze-16 mm+ kuphezulu kakhulu, nto leyo ebonakala kwixabiso lokugqibela le-FOB/CIF.
