Dab tsi yog qhov tuab tuab ntawm cov ntawv txias -rolled steel ntawv?
Txheem thickness yog 0.1mm-3.0mm. Cov ntawv nyias nyias lossis cov ntawv tuab tuaj yeem ua raws li cov cai tshwj xeeb.
Dab tsi yog cov qauv siv zog thiab tensile lub zog rau txias- dov steel ntawv?
Rau cov khoom siv sib xws (xws li SPCC), lub zog tawm los yog ≥130MPa, thiab lub zog tensile yog 300-400MPa. Cov nqi no txawv nyob ntawm cov khoom siv.
Dab tsi yog qhov kev xav tau ntawm qhov roughness rau txias -cov ntawv hlau dov?
Feem ntau nto roughness yog Ra 0.1-0.8μm. Cov qib roughness sib txawv tuaj yeem xaiv nyob ntawm daim ntawv thov.
Dab tsi yog qhov kev faib tawm ntawm hardness rau txias -rolled steel ntawv?
Lawv raug faib ua mos (HRB 60-80), ib nrab nyuaj (HRB 80-100), thiab nyuaj (HRB 100 thiab siab dua). Qhov tsim nyog hardness yuav tsum raug xaiv raws li kev thov tshwj xeeb.
Yuav ua li cas corrosion kuj ntawm txias - dov steel ntawv?
Lawv qhov kev tiv thaiv corrosion feem ntau yog nruab nrab. Kev kho deg xws li galvanizing thiab pleev xim yog xav tau los txhim kho corrosion kuj.
