Q: Qhov tsawg kawg nkaus txiav loj ntawm Q355 phaj yog dab tsi?
A: Qhov tsawg kawg nkaus txiav loj nyob ntawm txoj kev txiav thiab phaj thickness:
Nplaim txiav: yam tsawg kawg nkaus ntev / dav Ntau dua lossis sib npaug li 100mm
Plasma txiav: yam tsawg kawg nkaus ntev / dav Ntau dua lossis sib npaug li 50mm
Laser txiav: yam tsawg kawg nkaus ntev / dav Ntau dua lossis sib npaug rau 10mmRau qhov yuav tsum tau ua me me, peb tuaj yeem muab cov kev pabcuam txiav npluav lossis pom zoo rau lwm txoj kev ua haujlwm.**
Q: Q355 puas tuaj yeem khoov rau hauv lub voj voog ncig?
A: Yes. Q355 plate has good plasticity and can be bent into circular arcs of various radii. The minimum bending radius is related to the plate thickness and grade: for plates with thickness ≤10mm, the minimum bending radius is about 2 times the plate thickness; for plates with thickness >10mm, qhov tsawg tshaj plaws khoov vojvoog yog li 3-5 npaug ntawm lub phaj thickness. Rau cov phaj tuab, kub dabtsi yog khoov yog pom zoo kom tsis txhob tawg.
Q: Lub xeev xa khoom ntawm Q355 phaj yog dab tsi?
A: Cov kev xa khoom zoo tshaj plaws yog:
Kub-rolled xeev (HR): lub xeev xa khoom ntau tshaj plaws, tus nqi qis, tsim nyog rau feem ntau cov qauv.
Lub xeev zoo li qub (N): lub phaj yog rhuab mus rau 900-950℃thiab tom qab ntawd cua txias, nrog cov nplej loj, zoo dua toughness thiab weldability, haum rau cov khoom siv nrog kev ua haujlwm siab dua.
Tempered lub xeev (T): lub phaj yog rhuab mus rau ib tug tej yam kub thiab txias, nrog rau sab hauv kev nyuaj siab, haum rau precision structural qhov chaw.**
Q: Dab tsi yog qhov kam rau ntawm Q355 phaj thickness?
A: Raws li GB / T 3274-2017, lub thickness kam rau ua ntawm Q355 phaj yog muab faib ua ib txwm kam rau ua thiab meej kam rau ua:
Normal tolerance: for plates with thickness ≤16mm, the tolerance is ±0.5mm; for plates with thickness 16-40mm, the tolerance is ±0.8mm; for plates with thickness >40mm, qhov kam rau ua yog ± 1.0mm.
Precise tolerance: for plates with thickness ≤16mm, the tolerance is ±0.3mm; for plates with thickness 16-40mm, the tolerance is ±0.5mm; for plates with thickness >40mm, qhov kam rau ua yog ± 0.8mm.Peb tuaj yeem muab cov phaj nrog kev ua siab ntev raws li cov neeg siv khoom xav tau.**
Q: Qhov ntsuas qhov hnyav ntawm Q355 phaj yog dab tsi?
A: Cov qauv ntsuas qhov hnyav ntawm Q355 phaj yog: Nyhav (kg)=Thickness (mm) × Dav (m) × Length (m) × ntom (7.85 g / cm³) Piv txwv: A Q355 phaj nrog tuab 10mm, dav 2m, ntev 6m, nws qhov hnyav yog 10 × 2.
