Cov Qauv Steel Sections
1. Yam yuav tsum tau muaj
- Txuj: Phaj / profile dav 20mm
- Txo qhov profile: 12.5mm dav rau kev xav tau ntau dua
- Thickness: Raws li cov khoom siv niam txiv
- Nto tiav: Machined rau 3.2 µm Ra
2. Test raws tu qauv
-Txoj kev tswj tus nqi:
* Elastic cheeb tsam: 0.5 mm/min
* cheeb tsam yas: 2.0 mm/min
- Cov ntaub ntawv sampling: Yam tsawg kawg 100 ntsiab lus ua ntej yield
3. Kev ua haujlwm tsis zoo
- Young tus modulus (E)
-Yield point/yield stress
- Qhov kawg tensile zog
- Elongation thaum so
- Kev ntxhov siab piv xav tau
