Qhov Zoo
Cov Khoom Siv Zoo Tshaj Plaws
Sa662Grb kub - rolled phaj ua kom pom cov khoom ntiag tug. Nws cov txiaj ntsig tsawg kawg yog 622 MPA, uas qhia tau zoo heev siab tiv, ua kom nws muaj lub tsev ruaj khov thaum raug rau siab siab. Lub zog tensile ranges los ntawm 450 txog 585 MPA, qhia tau tias cov phaj steel muaj qhov ruaj khov thaum lub sij hawm ncab zoo thiab tsis yog qhov ua kom tawg. Nyob rau hauv cov nqe lus ntawm elongation, thaum lub ntsuas cua ntev yog 200 hli, elongation yuav loj dua los yog sib npaug rau 20%; Thaum lub ntsuas cua ntev yog 50 hli, elongation yuav tsum loj dua los yog sib npaug rau 23%. Cov ntsuas no kom muaj kev cuam tshuam zoo dua cov yasy thiab ductanced ntawm sa662grb siab rau cov phaj tsim kom haum rau ntau yam yuav tsum tau ua.
Zoo tsawg - kub cuam tshuam tawv tawv
Qhov kev cuam tshuam ntsuas kub ntawm sa662grb yog 20 degree, uas txhais tau tias cov steel phaj tseem tuaj yeem tswj hwm cov khoom siv tsis zoo hauv qhov chaw ib puag ncig. Hauv daim ntawv thov cov xwm txheej ntawm nruab nrab thiab qis {{{{}}} {{{{{{{}}} qhov kev cuam tshuam rau qhov tsis zoo rau cov ntaub ntawv ua haujlwm. Txawm li cas los xij, cia siab rau nws qhov kev ua tau zoo qis}} kub cuam tshuam nyuaj, sa662grb steel phaj tuaj yeem ua rau muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov hlab ntsha ruaj khov hauv qis- tej kev mob kub.
