Ipayipi Elingenamthungo Lensimbi Yesakhiwo i-EN 10210 S275J2H: Umhlahlandlela Ophelele Wezobuchwepheshe

Isingeniso

Ipayipi elingenamthungo lensimbi yesakhiwo i-EN 10210 S275J2H liyizinga lensimbi yesakhiwo elijwayelekile elingaxutshwe nalutho ngaphansi kwe-EN 10210-1 ejwayelekile yaseYurophu, elisetshenziswa kabanzi ezakhiweni zokwakha, ubunjiniyela bamabhuloho, ukukhiqizwa kwemishini, kanye namaphrojekthi engqalasizinda emhlabeni jikelele.

Onjiniyela kanye nochwepheshe bokuthenga bavame ukubuza: "Iyini impahla ye-S275J2H?", "Iyini i-S275J2H yesiShayina?", kanye "Iyini intengo yepayipi elingenamthungo le-EN 10210 S275J2H ngethani?" Lesi sihloko sinikeza umhlahlandlela wobuchwepheshe ophelele ohlanganisa ukuqokwa kwebanga, ukwakheka kwamakhemikhali, izakhiwo zemishini, izinhlelo zokusebenza, kanye nokucatshangelwa kokuthenga.

01 Kuyini Izinto ze-S275J2H?

Incazelo Yokuqokwa KwamaBanga

I-S275J2H iyibanga lensimbi yesakhiwo elingeyona i-alloy ngaphansi kwe-EN 10210-1 standard, eyenzelwe ngqo izingxenye zesakhiwo ezingenalutho eziqediwe ngokushisa. Uhlamvu ngalunye olusesigabeni lunencazelo ethile yobuchwepheshe:

Umlingiswa Incazelo
S Insimbi Yesakhiwo
275 Amandla okukhiqiza amancane angu-275 MPa ukuze ubukhulu bodonga bube ≤ 16mm
J2 Amandla omthelela ≥ 27J ku--20°C (ukuqina kwezinga lokushisa eliphansi)
H Ifanelekela izingxenye ezingenalutho (eziqediwe ngokushisa)

Inombolo yezinto ezibonakalayo ze-S275J2H yile1.0138, futhi ikhiqizwa njengensimbi ebulewe ngokuphelele (FF) ukuqinisekisa izakhiwo ezifanayo kanye nokushibilika okuhle kakhulu.

Izinga Elisebenzayo

Ipayipi elingenamthungo le-S275J2H lenziwa ngokuhambisana ne-EN 10210-1:2006– “Izingxenye ezingenalutho ezakhiweni eziqediwe ezishisayo zensimbi ezingezona i-alloy kanye nezinsimbi ezincane - Izimo zokulethwa kobuchwepheshe”.

Izidingo ezibalulekile ezihlanganiswa yile nqubo:

  • Imikhawulo yokwakheka kwamakhemikhali (ukuhlaziywa kweladle)
  • Izakhiwo zemishini ngobukhulu bodonga
  • Ukubekezelelana okulinganiselwe
  • Izidingo zekhwalithi ephezulu
  • Izinqubo zokuhlola nokuhlola

Uma kuqhathaniswa nezingxenye ezakhiwe kubanda ngaphansi kwe-EN 10219, izingxenye eziqediwe ngokushisa ze-EN 10210-1 zibonisa ukucindezeleka kwangaphakathi okuphansi kanye nokuqina okungcono kakhulu komthelela wokushisa okuphansi ngenxa yenqubo yokwakha eshisayo.

Izicelo Eziyinhloko

I-S275J2H inikeza ibhalansi enhle kakhulu yamandla, ukushibilika, kanye nokuqina kwezinga lokushisa eliphansi, okwenza ifaneleke ku:

  • Ukwakhiwa Kwesakhiwo:Izinhlaka zensimbi zezakhiwo eziphakeme, ama-trusses, izitebhisi, kanye nezinsimbi zokubambelela
  • Ubunjiniyela bebhuloho:Izinsika zamabhuloho, ama-abutment, ama-arches, kanye nezinhlelo ze-truss
  • Izakhiwo Zezimboni:Izisekelo zemishini esindayo, amabheringi okushelela, amapulatifomu okuphakamisa
  • Izakhiwo Zesimo Sezulu Esibandayo:Amaphrojekthi angaphandle eNyakatho Yurophu nasezindaweni eziphakeme lapho kudingeka khona izimo zesevisi -20°C

02 Ukwakheka Kwamakhemikhali kwe-EN 10210 S275J2H Ipayipi Elingenamthungo

Ukwakheka kwamakhemikhali kwe-S275J2H kumele kuhambisane ngokuqinile nezidingo ze-EN 10210-1. Amanani okuhlaziywa kweladle achazwe kanje:

Isici Isidingo se-EN 10210-1 (ubuningi %) Ukulawulwa Okuvamile Kwabesifazane
Ikhabhoni (C) 0.20 0.14 – 0.18
I-Silicon (Si) – 0.20 – 0.35
I-Manganese (Mn) 1.50 1.10 – 1.40

≤ 16 275
16 < t ≤ 40 265
40 < t ≤ 65 255

Amandla Okudonsa:
Ubukhulu Bodonga (mm) Amandla Okudonsa (i-MPa)
t ≤ 40 410 – 560
40 < t ≤ 65 400 – 540

Ukwelulwa (Okungenani):
Ubukhulu Bodonga (mm) Ukwelulwa (%)
t ≤ 40 22
40 < t ≤ 65 21

Ukuqina Komthelela:
Izinga Lokushisa Lokuhlola:-20°C
Amandla Aphansi Amuncwayo (KV₂):27J(i-longitudinal)

Okuvelele Kokusebenza Okubalulekile:
Amandla Okukhiqiza:≥ 275 MPa yobukhulu bodonga ≤ 16mm, ngokunciphisa kancane kancane izingxenye ezijiyile, ukugcina ≥ 255 MPa kufika ku-65mm
Amandla Okudonsa:Ibanga le-410-560 MPa, elihlinzeka ngomthamo omuhle kakhulu wokuthwala umthwalo
Ukwelulwa:≥ 22% iqinisekisa amandla okwanele okuguqulwa kwepulasitiki ukuze kugoqwe futhi kuqalwe ngokubandayo
Ukuqina Komthelela:Isiqinisekiso sokushisa okungenani esingu-27J ku--20°C, sihlangabezana nezidingo zesevisi yokushisa okuphansi kwezicelo zesimo sezulu esibandayo

04 Intengo ye-EN 10210 S275J2H Ipayipi Elingenamthungo

Intengo yepayipi elingenamthungo le-S275J2H iyahlukahluka kuye ngezimo zemakethe kanye nezidingo ezithile. Njengesithenjwa esijwayelekile:

Imakethe Yomhlaba Wonke ye-FOB:Cishe u-$600 – $850 ngethani (kuye ngokuthi usayizi, ubuningi, kanye nezidingo zesitifiketi)
Imakethe Yasekhaya YaseShayina (Kufakiwe Intela):Cishe i-RMB 4,500 – 5,500 ngethani (kuya ngokuguquguquka okusekelwe ezindleleni zezinto zokusetshenziswa kanye nomthamo we-oda)

Izici Eziyinhloko Ezithonya Amanani:

Isici Umthelela
Usayizi kanye nobukhulu bodonga Ububanzi obukhulu kanye nezindonga ezisindayo kwandisa izindleko zokugingqa, okunyusa intengo yeyunithi
Izidingo Zesitifiketi Ukumakwa kwe-CE, izitifiketi ze-EN 10204 Uhlobo 3.2, kanye nezindleko zokuhlola zenkampani yangaphandle
Isimo Sokulethwa Ukulethwa okujwayelekile kanye nokuqeda okulinganiselwe kubiza kakhulu kunokuqeda okushisayo
Izindleko Zezinto Ezingavuthiwe Ukuguquguquka kwentengo ye-billet yensimbi kanye ne-alloy kuthinta ngqo amanani epayipi aqediwe
Ubuningi be-oda Amavolumu amakhulu ngokuvamile afanelekela intengo engcono yamayunithi
Ukuze uthole amanani amanje kakhulu, sicela uxhumane ne-Womic Steel ngqo mayelana nosayizi wakho kanye nezidingo zakho zobuningi.

05 S275J2H Amabanga Alinganayo: Iyini I-Chinese Equivalent?

Umbuzo ovame ukubuzwa ngobunjiniyela uthi: "Iyini i-S275J2H yesiShayina elingana ne-S275J2H?" Ngokusekelwe ekuhlaziyweni okuphelele kokwakheka kwamakhemikhali kanye nezakhiwo zemishini, i-equivalent yesiShayina eseduze kakhulu yi-Q275D(GB/T 700).

Ukuqhathaniswa Kokwakheka Kwamakhemikhali

Imibuzo Evame Ukubuzwa 08

Q: Uyini umehluko phakathi kwe-S275J2H ne-S275J0H?
A:Womabili amazinga anezinga elifanayo lamandla (isivuno esingu-275 MPa), kodwa ahlukile ekushiseni kokuqina komthelela: I-S275J2H ivivinywa ngomthelela ku--20°C (27J), kuyilapho i-S275J0H ivivinywa ku-0°C (27J). I-S275J2H ikhethwa kakhulu ezindaweni ezibandayo.

Q: Uyini umehluko phakathi kwe-EN 10210 ne-EN 10219?
A:I-EN 10210 ihlanganisa izingxenye ezingenalutho ezakhiweni eziqediwe ngokushisa (ezakhiwe futhi zaqediwe emazingeni okushisa aphezulu), kuyilapho i-EN 10219 ihlanganisa izingxenye ezakhiwe zibandayo (ezakhiwe emazingeni okushisa asekamelweni). Izingxenye eziqediwe ngokushisa ngokuvamile zinikeza ukucindezeleka okuphansi kwangaphakathi, ukuzinza okungcono kobukhulu, kanye nokuqina okuphezulu kwezinga lokushisa eliphansi.

Q: Ingabe i-S275J2H ifanelekile ukushisela?
A:Yebo. Uma i-CEV iphansi (≤ 0.41%), i-S275J2H ibonisa ukushiselwa okuhle kakhulu. Ukushisa ngokuvamile akudingeki uma ubukhulu bungaphansi kuka-20mm. Ezigabeni ezijiyile, kusebenza izinqubo zokushiselwa ezijwayelekile.

Q: Lingakanani izinga lokushisa eliphansi lomklamo we-S275J2H?
A:Ngokwe-EN 1993 (i-Eurocode 3), i-S275J2H ingasetshenziswa phansi ku--20°C ngokuhlolwa komthelela we-Charpy okuqinisekiswe ku--20°C (ubuncane obungu-27J).

Q: Lingakanani izinga lokushisa eliphezulu lesevisi ye-S275J2H?
A:Izinhlelo zokusebenza zesakhiwo ngokuvamile zisebenzisa i-S275J2H kuze kufike cishe ku-350-400°C. Ukuze uthole isevisi eqhubekayo yokushisa okuphezulu, bheka isiqondiso sokuklama se-EN 1993.

Q: Ingabe i-S275J2H inganikezwa isitifiketi se-EN 10204 Type 3.2?
A:Yebo. I-Womic Steel ihlinzeka njalo nge-S275J2H ngezitifiketi zohlobo 3.2 eziqinisekiswe yizinhlangano ezigunyaziwe yi-EU okuhlanganisa i-TÜV, i-BV, i-SGS, kanye ne-LR.
