1. Kufotokozera mwachidule za mbale yachitsulo ya S355J0W:
S355J0W ndi chitsulo chokhazikika cha ku Europe chomwe sichikhala ndi dzimbiri, chomwe ndi mbale yachitsulo yolimbana ndi nyengo. Ndi chitsulo chochepa cha alloy chopangidwa mwa kuwonjezera zinthu zina za alloy ku zitsulo wamba. Kukaniza kwa mlengalenga kwa chitsulo chosasunthika ndi 2-8 nthawi ya chitsulo cha kaboni wamba, ndipo imakhala ndi zida zabwino zamakina, zida zowotcherera, ndi zina zambiri, ndipo pakapita nthawi yayitali, zimawonekeranso kuti kukana kwa dzimbiri.
2. S355J0W inapititsa patsogolo chitsulo chosamva dzimbiri mumlengalenga
Kuchuluka kwa zinthu zopangira ma alloying kumawonjezeredwa kuchitsulo, monga P, Cu, Cr, Ni, Mo, kuti awonjezere kukana kwa dzimbiri la mpweya, ndipo chifukwa cha nyengo, oksidi yoteteza yokha idzasinthidwanso. zitsulo zoyambira.
3. Kutumiza kwa S355J0W:
Kuperekedwa otentha adagulung'undisa, normalized kapena normalized adagulung'undisa chikhalidwe.
Zinayi, S355J0W zitsulo mbale mkulu muyezo:
S355J0W zida EN10025-5:2004 muyezo.
5. S355J0W inapititsa patsogolo chitsulo chosapanga dzimbiri mumlengalenga
Kuchuluka kwa zinthu zopangira ma alloying kumawonjezeredwa kuchitsulo, monga P, Cu, Cr, Ni, Mo, kuti awonjezere kukana kwa dzimbiri la mpweya, ndipo chifukwa cha nyengo, oksidi yoteteza yokha idzasinthidwanso. zitsulo zoyambira.
6. Mphamvu zathu zoperekera:
1. Likupezeka zitsulo mbale specifications osiyanasiyana: makulidwe 8-700mm, m'lifupi 1500-4020mm, kutalika 4000mm-17000mm, unit kulemera kwa matani 30.00. Zitsulo zazikulu za gauji zimapezekanso mukapempha.
2. Mitundu ya mbale zazitsulo zomwe zilipo: mbale za carbon structural steel plates, low-alloy high-mphamvu zitsulo mbale, zitsulo zopangira milatho, zitsulo zamatabwa zomangira nyumba, zitsulo zopangira zombo ndi nsanja za m'mphepete mwa nyanja, mbale zachitsulo za boilers ndi zotengera zopanikizika, zitsulo. mbale za nkhungu, mbale zachitsulo zamagulu a aloyi, Pali mitundu 12 ya mbale zazitsulo zamapaipi amafuta ndi gasi, mbale zachitsulo zolimba kwambiri komanso zolimba kwambiri, mbale zachitsulo zosapanga dzimbiri, ndi mbale zachitsulo zophatikiza, zokhala ndi zoweta zopitilira 300. mitundu yakunja.
3. Zopezeka pazofunikira zozindikiritsa zolakwika, Z15-Z35 makulidwe amayendedwe amayendedwe ofunikira, mphamvu zazikulu komanso zofunikira zolimba kwambiri ndi mbale zina zachitsulo.
4. Ikhoza kuperekedwa malinga ndi miyezo ya dziko, zitsulo zazitsulo, miyezo ya ku America AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, ISO yapadziko lonse ndi zina.
Zisanu ndi ziwiri, S355J0W zitsulo zazitsulo zopangidwa ndi mankhwala (kusanthula kwa smelting) ndi S355J0W makina amakina ndi katundu wamakina:
