Dab tsi yog cov thickness ntau ntawm Q355 steel phaj hauv kev tsim kho?
Cov qauv hlau tsis zoo: Cov kab teeb thiab kab feem ntau siv 12-30mm; txuas txuas ntev thiab cov khoom hnyav feem ntau siv 20-50mm; curtain phab ntsa embedded qhov chaw thiab purlins feem ntau siv 8-16mm.
7. Lub tsev twg yuav tsum siv Q355 steel phaj?
Siab -nce lub tsev ncej kab, steel beams, thiab core tube Cheebtsam.
Loj -span spatial structures (gymnasiums, airport terminals) main beams thiab trusses.
Load-cov khoom siv bearing nyob rau hauv cov cheeb tsam nrog seismic fortification siv ntawm 8 degrees los yog siab dua.
Cov qauv hlau raug rau cov khoom hnyav thiab qis - qhov kub thiab txias.
8. Thaum twg thiaj li tsim nyog xaiv Z-kev taw qhia Q355 steel daim hlau (Z15/Z25/Z35)?
Thaum cov hlau phaj thickness ntau dua los yog sib npaug li 40 hli thiab raug rau tensile quab yuam raws lub phaj thickness kev taw qhia (xws li tuab - phab ntsa kem kab thiab hloov txheej txheej), Z- kev taw qhia steel yuav tsum raug xaiv. Rau cov nodes tseem ceeb nyob rau hauv siab -nce vaj tse, Z25 / Z35 steel yog pom zoo, nrog rau seem txo tus nqi siab tshaj los yog sib npaug rau 25% thiab 35% raws li.
9. Cov ntaub ntawv dab tsi yuav tsum tau kuaj xyuas thaum lub sijhawm lees paub ntawm Q355 steel daim hlau thaum tuaj txog?
Hoobkas zoo daim ntawv pov thawj thiab daim ntawv pov thawj ntawm conformity. Lub cub tawg batch tooj, tshuaj muaj pes tsawg leeg, txhua yam khoom, Z-cov khoom taw qhia (yog tias tsim nyog), thiab cov ntaub ntawv cuam tshuam toughness yuav tsum raug txheeb xyuas.
10. Dab tsi yog cov batch faib thiab cov khoom rau kev rov- tshuaj xyuas Q355 steel phaj thaum tuaj txog?
Kev soj ntsuam batch: Rau tib qib, rauv batch tooj, thiab specification, txhua txhua 60 tons yog ib batch; tsawg dua 60 tons yog suav tias yog ib pawg.
Re-cov khoom tshuaj xyuas: Cov khoom muaj zog, lub zog tensile, elongation, txias dabtsi yog khoov, cuam tshuam toughness; rau Z-kev taw qhia steel, ntu txo tus nqi kuj ntsuas.
