Q235 Hlau Chev yog ib qho kev ua kom zoo ntawm cov khoom siv hlau
1. Cov Khoom Yooj Yim
Cov Qauv Txheem: Q235 yog cov hlau qauv hlau teev nyob rau hauv Suav GB / T 700 tus qauv, coj mus rau International Standard A36 (tab sis tsis zoo ib yam).
Tshuaj lom neeg muaj pes tsawg leeg (muaj nuj nqis):
Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0.22%
Silicon (si): tsawg dua los yog sib npaug rau 0.35%
Manganese (MN): Tsawg dua lossis sib npaug rau 1.4%
Phosphorus (p), leej faj (s): tsawg dua los yog sib npaug rau 0.045% (impurities, cuam tshuam rau weldability thiab kev nruj).
2. Cov Khoom Siv Neeg Kho Tshuab
Tos lub zog: ntau dua los yog sib luag rau 235 MPa ("235" hauv "Q235" yog hais txog kom muaj zog zog).
Tensile lub zog: 375-500 mpa.
Txiaj: ntau dua los yog sib npaug rau 26% (rau thicknesses tsawg dua los yog sib npaug nrog 16 hli), nrog cov yas zoo thiab muaj txiaj ntsig zoo.
3. Cov lus qhia txog cov roj
Thickness: feem ntau 0.3mm rau 6.0mm (txias- rolled coils yog thinner, kub} polls yog thicker). Dav: Feem ntau 1000mm-2000mm, customizable.
Chev Nyhav: Feem ntau 10-30 tons, nyob ntawm cov chaw tsim khoom.
4. Nto Kho
Kub -}}}} rolled steel chev: nplaim nplai yog feem ntau tshem tawm pickling (piv txwv li, sphc chev).
Txias -}} rolled steel chev: nto du, npaj rau kev ua tiav xws li galvanizing thiab xim txheej.
5. Kev thov
Kev Tsim Kho: Hlau qauv ntas, ru tsev, thiab phab ntsa (yuav tsum muaj xeb ntsug kev tiv thaiv).
Kev tsim khoom: ntu automotive, tshuab tshuab, thiab ntim khoom.
Cov Khoom Siv Hauv Tsev: Housings thiab nkhaus (feem ntau txias - rolled chev).
Cov kav dej: Welded kav thiab kauv kav dej (feem ntau kub - rolled chev).
6. Ua cov kev ceev faj
Vuam: Yooj yim rau weld, tab sis kev tawm tswv yim tshav kub yuav tsum tau tswj kom tsis txhob muaj khaub thuas txias.
Corrosion tiv thaiv: Galvanizing lossis cov xim yuav tsum muaj rau cov chaw nthuav tawm (Q235 muaj huab cua tsis kam).
Stamping: Txias - rolled chev yog haum rau kev sib sib zog nqus duab, thaum kub {1} {rolled coil yuav tsum tau muaj kev txhawb nqa kom txhim kho kev sib txuas.
7. Kev ua lag luam thiab kev yuav khoom
Tus Nqi Siv Khoom Siv: Kev hloov pauv hauv kev lag luam steel, kub-}} rolled chev yog kwv yees li 4,000-5,000 yuan / 2).
Kev yuav cov ntsiab lus tseem ceeb: Nco ntsoov hais meej cov tuab tuab, cov qauv kev ua tiav (piv txwv li, GB / T 3274).
8. Piv ntawm cov qhab nia zoo sib xws
Q345: Muaj lub zog siab dua tab sis tus nqi siab dua, thiab yog siv rau cov khoom loj dua .. {} cov kabmob chaw.
Spcc: Txias -}} daim ntawv, ua ntej ua haujlwm zoo thiab yog siv rau kev ntsuas tshuab.
