Chitsulo cha ASTM SA283GrC/Z25 choperekedwa chili mu mawonekedwe otentha opindidwa SA283GrC mawonekedwe otumizira:
Mkhalidwe wa kutumiza wa SA283GrC: Kawirikawiri pamene kutumiza kukutentha kwambiri, mkhalidwe weniweni wa kutumiza uyenera kufotokozedwa mu chitsimikizo.
Mtengo wa SA283GrC wa kapangidwe ka mankhwala: Zindikirani: Kapangidwe ka mankhwala enieni mu chitsimikizo cha fakitale yachitsulo ndi komwe kudzapambana.
Kaboni C: ≤0.24 Si: (mbale yachitsulo ≤40) ≤0.40 (mbale yachitsulo > 40) 0.15-0.40
Manganese Mn: ≤0.90 Sulfure S: ≤0.040 Phosphorus P: ≤0.035
Mkuwa Cu: 0.20 kapena kuchepera
Mbale yachitsulo ya SA283GrC ndi yoyenera kupangira ma riveting, bolting ndi welding pa milatho ndi nyumba. Ndi chitsulo chopangidwa ndi kaboni chomwe chimagwiritsidwa ntchito kwambiri komanso chopangidwa ndi chitsulo chopangidwa ndi kaboni.
Mkhalidwe wotumizira mbale yachitsulo ya SA283GrC: kugwedezeka kotentha, kugwedezeka kolamulidwa, mkhalidwe wabwinobwino wotumizira
Zipangizo zomangira ng'anjo yophulika ya SM400ZL mbale yachitsulo:
SM400ZL ndi mbale yachitsulo yolimba kwambiri ya ku Japan yopangidwa ndi chipolopolo chosinthira. Muyezo uwu umatchula kukula, mawonekedwe, zofunikira zaukadaulo, njira zoyesera, malamulo owunikira, kulongedza, zizindikiro ndi satifiketi yaubwino wa mbale zachitsulo za ng'anjo yophulika, chosinthira ndi zipolopolo za ng'anjo yotentha. Imagwira ntchito pa mbale yachitsulo ya chipolopolo cha ng'anjo yokhala ndi makulidwe a 8mm ~ 200mm. Kupatuka kwa makulidwe koyipa kwa mbale yachitsulo ya SM400ZL kumangokhala -0.25mm, ndipo malo olekerera makulidwe ayenera kutsatira GB/T709.
Mbale yachitsulo ya S355NL [yokhuthala 8-200] kapangidwe ka kudula, mndandanda wa zinthu:
Muyezo waukulu wa S355NL: EN10025-3: dzina lonse: normalizing/normalizing rolled weldable fine grain structural steel plate. Muyezo uwu ndi EN10025-1 pamodzi zimalowa m'malo mwa EN 10113-1:1993 hot-rolled weldable fine grain structural steel products Part I: General conditions and EN 10113-2:1993 hot-rolled fine grain structural steel products Part II: normalizing/normalizing rolled steel conditions. Pamene kutentha kwa giredi sikuli kotsika kuposa - 20 ° C, mtengo wocheperako wa mphamvu yokhudza yomwe yatchulidwa umafotokozedwa mu NL; pamene kutentha sikuli kotsika kuposa - 50 ° C, mtengo wocheperako wa mphamvu yokhudza yomwe yatchulidwa umafotokozedwa mu NL.
2. Tanthauzo lofanana la kalata ya S355NL yachitsulo:
S: chitsulo chomangira, N: boma, likulu L: mulingo wa mphamvu yocheperako yomwe yatchulidwa pamene kutentha sikuli kotsika kuposa - 50 ° C
Mbale yachitsulo ya S355ML [yokhuthala 8-200mm] yozungulira ndi thermomechanical
Mbale yachitsulo ya S355ML imaperekedwa mu thermomechanical rolling state
Zofunikira pa Kupanga Mankhwala a S355ML
C: ≤0.14,Si: ≤0.5,Mn: ≤1.6，P:≤0.025，S:≤0.02,Nb:≤0.05,V:≤0.1,A 1
Mbale yachitsulo ya S355ML ndi chitsulo chopangidwa ndi tirigu wofewa chopindidwa ndi kutentha, chomwe chili m'gulu la mbale zachitsulo zolimba kwambiri. Ndi chinthu chopindidwa chosalala chomwe chili ndi makulidwe osapitirira 120mm ndi chinthu chachitali chomwe chili ndi makulidwe osapitirira 150mm. S amatanthauza chitsulo chopangidwa ndi nyumba, 355 akusonyeza kuti phindu laling'ono la makulidwe oyenera osapitirira 16mm ndi 355MPa, ndipo M ikuyimira kutumiza kwake, ndiko kuti, kugwedezeka kotentha. Lamulo ndilakuti kugwedezeka pa kutentha kosachepera madigiri 50 kumawonetsedwa ndi chilembo chachikulu L. S355 ndi chitsulo chopangidwa ndi nyumba chosakhala ndi alloy.
Kugwiritsa ntchito mbale yachitsulo ya S355ML
Kuwonjezera pa chitsulo cha EN10,025-1, pulani yachitsulo yomwe yatchulidwa mwapadera mu muyezo uwu imagwiritsidwanso ntchito pazinthu zonyamula katundu za nyumba zolumikizidwa zomwe zimagwiritsidwa ntchito mozungulira milatho, malo otsetsereka, matanki osungiramo zinthu, matanki operekera madzi, ndi zina zotero komanso ndi kutentha kochepa.
