Q: Cov kev kho deg twg tuaj yeem siv rau Q355 phaj?
A: Cov kev kho saum npoo feem ntau suav nrog: tiv thaiv- xeb roj txheej (rau luv- lub sijhawm cia), tua blasting thiab pleev xim (rau ntev-} siv sijhawm), galvanizing (rau corrosion kuj), thiab epoxy resin txheej (rau qhov chaw hnyav).
Q: Puas yuav tsum tau preheating rau vuam Q355 phaj?
A: Rau daim hlau nrog thickness tsawg dua los yog sib npaug rau 20mm thiab ambient kub Ntau tshaj los yog sib npaug rau 5 degree, preheating tsis tas yuav tsum tau. Rau daim hlau nrog thickness> 20mm, los yog tsis tshua muaj ambient kub, los yog siab ceev welding, preheating rau 80-150℃yog pom zoo kom tiv thaiv kom txhob txias tawg.
Q: Cov khoom siv vuam zoo li cas rau Q355 phaj?
A: Cov khoom siv vuam pom zoo: E5015 (J507), E5016 (J506) rau phau ntawv arc vuam; ER50-6 rau roj hlau arc vuam; H08Mn2Si rau submerged arc vuam.
Q: Dab tsi yog daim ntawv thov tseem ceeb ntawm Q355 phaj?
A: Nws yog dav siv nyob rau hauv: kev tsim kho engineering (steel qauv vaj tse, txuas hniav, scaffolds), mechanical manufacturing (machinery thav duab, siab hlab ntsha, cranes), kev thauj mus los (nkoj hulls, tsheb ciav hlau carriages, tsheb thav duab), thiab zog engineering (cua turbine yees, fais fab kis tau tus yees, roj pipelines).
Q: Q355 puas siv tau rau cov hlab ntsha siab?
A: Yog, Q355 phaj tuaj yeem siv rau cov hlab ntsha qis thiab nruab nrab (ua haujlwm siab tsawg dua lossis sib npaug li 4MPa) tom qab dhau qhov kev tshuaj xyuas ultrasonic. Rau siab - cov hlab ntsha siab, peb pom zoo kom siv cov hlab ntsha tshwj xeeb xws li Q345R.
