Ama-Raw material
Insimbi engahlanganisiwe necolekileyo yokusanhlamvu.
Insimbi engafakwanga izimfanelo ezine ezithi JR, JO, J2, kanye ne-K2 zicacisiwe.
Izinsimbi zokusanhlamvu ezinhle: izimfanelo ezine ze-N ne-NL zicacisiwe.
Izinsimbi zokusanhlamvu ezinhle ziyizinsimbi ezinesakhiwo sokusanhlamvu esihle, ezinosayizi wezinhlamvu ze-ferrite ≥ 6.
I-BS EN 10210 Igama Lensimbi
Ezingxenyeni ezingenalutho zensimbi engeyona i-alloy igama lensimbi liqukethe
Isibonelo: BS EN 10210-S275J0H
iqukethe izingxenye ezine:S, 275, J0, kanye no-H.
1.S: kukhombisa ukuthi insimbi yesakhiwo.
2.Inani lenombolo(275): ukujiya ≤ 16mm kobuncane bamandla esivuno ashiwo, ku-MPa.
3.JR: ikhombisa ukuthi kumazinga okushisa asekamelweni anezici ezithile zomthelela;
J0: ikhombisa ukuthi ku-0 ℃ enezici ezithile zomthelela;
J2 noma K2: kukhonjiswe ku -20 ℃ ngezici ezithile zomthelela;

5.H: ichaza isigaba esingenalutho.
Izimo Zokulethwa kwe-BS EN 10210
JR, J0, J2 kanye ne-K2 - ukushisa kuphelile.
I-N ne-NL - ijwayelekile.Okujwayelekile kufaka phakathi ukugoqwa okujwayelekile.
I-JR, J0, J2 kanye ne-K2 - iyasebenza kakhulu
I-N kanye ne-NL - Ukulinganisa.Ukwejwayelekile kuhlanganisa ukugoqa okujwayelekile.
Kungase kudingeke ukuthi izingxenye ezingenalutho ezingenamthungo ezinogqinsi olungaphezulu kuka-10 mm, noma lapho i-T/D ingaphezu kuka-0,1, ukusebenzisa ukupholisa okusheshisiwe ngemva kokuqinisa ukuze kufezwe isakhiwo esihlosiwe, noma ukucisha uketshezi kanye nokushisa ukuze kuzuzwe ukupholisa okucacisiwe. izakhiwo.
Ezingxenyeni ezingenalutho ezingenamthungo ezinobukhulu bodonga obudlula u-10 mm, noma uma i-T/D ingaphezu kuka-0.1, ukupholisa okusheshisiwe ngemva kokwenza i-austenitization kungase kudingeke ukuze kuzuzwe isakhiwo esifiswayo, noma ukucisha uketshezi nokufudumeza ukuze kuzuzwe izici zomshini ezishiwo.
Ukwakhiwa Kwekhemikhali kwe-BS EN 10210
Izinsimbi ezingezona i-alloy - Ukwakheka kwamakhemikhali
Fine Grain Steels - Ukwakheka kwamakhemikhali
Lapho kunqunywa i-CEV ifomula elandelayo izosetshenziswa:
CEV=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
Ukuchezuka Ekubunjweni Kwamakhemikhali
Izakhiwo Zemishini ye-BS EN 10210
Ukunciphisa ingcindezi ngaphezu kuka-580 °C noma isikhathi esingaphezu kwehora elilodwa kungase kuholele ekuwohlokeni kwezakhiwo zemishini.
Izinsimbi ezingezona i-alloy - Izakhiwo Zemishini
Fine Grain Steels - Mechanical Properties
Izivivinyo Zomthelela
Ukuhlolwa komthelela akudingekile uma ubukhulu obucacisiwe < bungu-6 mm.
Izibonelo ezijwayelekile ezinophawu lwe-V ngokuya nge-EN 10045-1 zizosetshenziswa.
Uma ukushuba komkhiqizo okuzisholo kunganele ukulungiselela ama-specimens ajwayelekile, ukuhlolwa kuzokwenziwa kusetshenziswa izibonelo ezinobubanzi obungaphansi kuka-10 mm, kodwa bungabi ngaphansi kuka-5 mm.
Ukushisela
Izinsimbi ku-BS EN 10210 ziyakwazi ukushisela.
I-EN 1011-1 kanye ne-EN 1011-2 icacisa izidingo ezijwayelekile zemikhiqizo eshiselwe.
Ukuqhekeka okubandayo endaweni yokushisela kuyingozi enkulu njengoba ukushuba komkhiqizo, izinga lamandla, kanye nokukhuphuka kwe-CEV.
Ukubekezelela Dimensional
Ukubekezelela Isimo, UkuQopha kanye NeMisa
Ukubekezelela Ubude
Ukuphakama Kwe-Seam ye-SAW Weld
Ukubekezelela ukuphakama kwe-weld seam yangaphakathi nangaphandle yezingxenye ezingenalutho ze-arc ezishiselwe.
| Ubukhulu, T | Ubukhulu bobude be-weld bead, mm |
| ≤14,2 | 3.5 |
| >14,2 | 4.8 |
Izinga le-BS EN 10210 limboza yomibili imikhiqizo yengxenye engenamthungo neshiselwe eshiselwe okushisayo eqediwe.Izinqubo zokushisela eziyinhloko yi-resistance welding (ERW) kanye ne-submerged arc welding (SAW).Amapayipi ensimbi e-ERW awabonakali, kuyilapho ama-SAW evamise ukuba mabi futhi abonakale kakhulu ngenxa ye-SAW.
Ukubukeka Kobuso
Ingaphezulu lizoba nesiphetho esibushelelezi esihambisana nendlela yokukhiqiza esetshenzisiwe;
Uma ukujiya kungaphakathi kokubekezelelana, amaqhuqhuva, ama-grooves, noma ama-longitudinal grooves angajulile abangelwa inqubo yokukhiqiza avunyelwe.
Kufakwe amagalani
Imikhiqizo eku-BS EN 10210 ilungele ukwelashwa kwe-dip galvanizing eshisayo.
I-EN ISO 1461 kufanele isetshenziselwe ukucacisa izidingo zokumboza.
Izingubo ze-Zinc zisetshenziswa ngokucwiliswa esixazululweni esincibilikisiwe esiqukethe okungenani i-98% yokuqukethwe kwe-zinc.
Ukulungiswa Kweziphambeko Zobuso
Ukulimala okungaphezulu kungase kususwe ngokugaya umkhiqizi, inqobo nje uma ukujiya okulungisiwe kungengaphansi kobukhulu obuncane obuvunyelwe.
Uma kukhiqizwa inqubo yokushisela, ukulungiswa kwama-welds akuvunyelwe ngaphandle kwe-arc welding engaphansi kwamanzi.
Ipayipi lensimbi elingelona ingxubevange lingalungiswa ngokushisela umzimba wepayipi.Ipayipi lensimbi ye-alloy angeke lilungiswe ngokushisela umzimba.
I-BS EN 10210 Ukumaka
Okuqukethwe kokumaka ipayipi lensimbi kufanele kuqukathe:
igama lensimbi, isb EN 10210-S275JOH.
igama noma uphawu lokuhweba lomkhiqizi.
inombolo kamazisi, isb inombolo ye-oda.
I-BS EN 10210 amashubhu ensimbi angamakwa ngezindlela ezahlukahlukene zokuqinisekisa ukukhonjwa kalula nokulandeleka, kungaba ngokudweba, ukugxiviza, amalebula okunamathela, noma amalebula engeziwe, angasetshenziswa ngawodwana noma ahlanganiswe.
Izinhlelo zokusebenza
Ngenxa yamandla ayo aphezulu, ukuqina okuhle, kanye nokushisela, i-BS EN 10210 iyakwazi ukumelana nenhlobonhlobo yendawo nezimo zokulayisha futhi isetshenziswa kabanzi ezinhlelweni ezihlukene zesakhiwo.
Izakhiwo zokwakha: isb. amathambo ezakhiwo eziphakeme, izakhiwo zophahla ezinkundleni zemidlalo, nezinto ezisekela amabhuloho.
Onjiniyela bamakhemikhali: amafreyimu nezisekelo zemishini nemishini esindayo.
I-Civil Engineering: njengezisekelo zomhubhe, amakholomu ebhuloho, nezinye izakhiwo ezithwala umthwalo.
Ingqalasizinda yezokuthutha: kufaka phakathi izingxenye zemigwaqo namabhuloho wesitimela.
Umkhakha wezamandla: isb. imibhoshongo yenjini yomoya kanye nezinye izingxenye zesakhiwo sezinsiza zamandla.
Singabakhiqizi nabahlinzeki bepayipi lensimbi yensimbi esezingeni eliphezulu abavela eChina, futhi siphinde sibe nesitoko sepayipi sensimbi esingenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
