Dab tsi yog txias -rolled DC06?
DC06 yog ib qho ultra-cov pa roj carbon tsawg uas muaj qhov ua tau zoo heev. Cov tshuaj muaj pes tsawg leeg ntawm DC06 yog txhais tau meej los xyuas kom meej tias cov khoom muaj cov khoom siv kho tshuab uas xav tau. Feem ntau, DC06 muaj qhov siab tshaj plaws ntawm 0.01% carbon, qhov siab tshaj plaws ntawm 0.20% manganese thiab tsuas yog qhov tsawg kawg nkaus ntawm phosphorus thiab sulfur. Qhov me me ntawm cov ntsiab lus alloying no ua rau cov hlau tshwj xeeb formability thiab weldability.
Cov khoom siv kho tshuab ntawm DC06 kuj tau hais meej meej. Cov khoom muaj lub zog siab tshaj plaws ntawm 120 MPa thiab lub zog tensile ntawm 270 thiab 350 MPa. Tsis tas li ntawd, DC06 muaj qhov elongation ntawm kev tawg ntawm yam tsawg kawg 40%, uas qhia txog nws cov formability zoo heev. Cov khoom no ua rau DC06 tshwj xeeb tshaj yog tsim nyog rau kev tsim cov khoom sib txawv thiab meej uas yuav tsum tau muaj kev ua haujlwm siab, xws li sib sib zog nqus- rub lub cev hauv kev lag luam tsheb lossis cov khoom siv hauv tsev hauv kev lag luam.
Tshuaj muaj pes tsawg leeg - EN 10130 siv txwv
Hauv qab no yog cov lus sib sau ua ke ntawm cov tshuaj lom neeg ntau tshaj plaws uas feem ntau siv thaum xaj DC01-DC06 ib EN 10130 (tus nqi yog qhov siab tshaj plaws tshwj tsis yog qhia lwm yam). Cov no yog cov qauv qab nthab; mills feem ntau tshaj tawm cov kev txheeb xyuas tseeb ntawm daim ntawv pov thawj zeb xeem (MTC).

FAQs
Q: DC01 puas tuaj yeem welded?
A: Yog - DC01 thiab lwm qib DC yog weldable los ntawm cov txheej txheem txheej txheem (MIG/MAG, TIG, qhov chaw tiv thaiv), tab sis tswj cov cua sov thiab khiav cov kev kho mob ua ntej / tom qab yog tias cov xim los yog galvanizing koom nrog. Rau cov pa roj carbon tsawg heev DC06, vuam tsis yuav tsum tsis txhob embrittlement ntawm ntug.
Q: DC qib twg muab qhov zoo tshaj plaws sib sib zog nqus nqus?
A: DC05 / DC06 muab qhov siab tshaj plaws ductility thiab qis tshaj tawm qab nthab hauv cov tsev neeg DC; DC06 feem ntau xaiv qhov twg qhov siab tshaj plaws elongation thiab qhov tsawg kawg nkaus springback yog qhov tseem ceeb. Kev ntsuam xyuas tus qauv tseem yog qhov tseem ceeb.
Q: Dab tsi saum npoo tiav kuv yuav tsum qhia kom pom cov panels?
A: Order DC01-A (ntau dua saum npoo zoo) lossis thov kom muaj Ra roughness thiab tawv nqaij- dhau qhov kawg; kuj nug txog kev tiv thaiv roj lossis tshuaj tiv thaiv tus ntiv tes thaum xav tau.
Q: Cov qib DC puas tuaj ua ntej-galvanized?
A: EN 10130 npog cov khoom tsis muaj coated; Galvanized variants yog muab raws li EN 10152 (DC + ZE). Qhia kom meej txheej txheej thiab tom qab- kho thaum yuav tsum tau muaj kev tiv thaiv corrosion.
