1. Cov laj thawj ntawm cov ntsiab lus rau kev sib raug zoo
Cov ntsiab lus muaj roj carbon tsawg: Nws cov ntsiab lus carbon (~ 0.14-0.22%) yog ib nrab, tsis txhob tawg ntawm qhov txiav ntug (tsis zoo li siab- Cov hlau nplaum).
Zoo thermal conductivity: Cov khoom nqus laser lub zog muaj zog, txo cov hauv zos overheating thiab ua kom nruj kev txiav.
Tsawg Tsawg Alloy Kev cuam tshuam: Lw Alloy cov ntsiab lus tsis cuam tshuam ntau yam kev nqus cov laser lossis tsis zoo {{}} alloy alloy steels (piv txwv li cov hlau stainless) uas yuav xav tau laser ntau dua.
2. Raug Laser Txiav Qhov Tsis Muaj (Siv)
Pab roj: Cov pa oxygen yog qhov nyiam tshaj plaws rau feem ntau thicknesses - Nws nrawm sib zog sib txuas ntawm cov khoom siv, nce ceev thiab ua kom huv. Rau daim hlau nyias (<3mm), nitrogen can be used to avoid oxidation (if a rust-free edge is required).
3. Qhov Zoo ntawm Laser Txiav rau Q235NH
Siab Precision: Nqaim Kerf Dav (0.1 -0.3mm) thiab minimal thermal deformation, tsim nyog rau cov duab ua kom zoo nkauj, tshuab sib xyaw).
Du txiav ntug: Qhov txiav saum npoo yog tiaj tus uas tsis muaj burrs; Tshaj tawm {{0- kev (piv txwv li, Deburring) yog tsawg heev lossis tsis tsim nyog.
Ua tau zoo: Ceev tshaj li Plasma txiav rau nyias - - cov khoom siv hauv nruab nrab, nrog cov khoom siv qis dua.
4. Sau ntawv rau kev ua haujlwm
Saib: Tshem cov roj, xeb, lossis khib nyiab los ntawm phaj ua ntej txiav -}}}}}}}}} ens້ອງ tuaj yeem ua rau txiav tawm lossis ua kom lub lens laser.
THICKNESSIONAL QAIB: Laser cutting is most efficient for Q235NH plates ≤25mm. For thicker plates (>25mm), ntshav txiav los yog nplaim taws txiav tej zaum yuav tau tus nqi ntau-}}} ua tau zoo.
Ntug kev tiv thaiv: Tom qab txiav, ntug liab qab (tsis muaj ib txheej xeb) yog nquag rau corrosion. Txiav txim siab thov ib qho kev txwv tsis muaj ib ntus lossis ua kom muaj kev sib txuam ntawm ib txwm txheej (raws li tau tham txog cov lus nug ua ntej) los tiv thaiv tus ntug.
