Phosphorus / Sulfur: Tsawg dua lossis sib npaug rau 0.04% txhua
(Hlau ua kom muaj kev sib npaug).
2. HRC Hollow Sect: Cov Lus Txhais
Hrc: Sawv rauKub Tsav Kev Lag Luam Zoo, Txias - muaj tsim.
Puab: Hollow cov ntu (hss) tsim los ntawm txias {{} {} {}}}}}}}} pa taws, lossis cov duab plaub.
Cov txheej txheem tsim khoom:
Kub - rolled steel coils yog ib qho.
Txias - tsim rau hauv cov duab ntawm yob txoj kev ua lossis nias braking.
Welded longitudinally (leeg welded).
Sizing / xov rau zaum kawg.
3. Neeg Kho Tshuab & Tshuaj Kho Mob
Lub zog: Ntais ntawv Astm A36 xav tau:
Tos: ntau dua lossis sib npaug nrog 250 mpa|Tensile: 400-550 mpa.
Kev ua siab loj: Haum rau dabtsi yog khoov / vuam.
Kev ua tshuaj: Zoo ib yam li cov paib / cov tuav tab sis zoo rau kev muaj peev xwm. Tsawg cov pa roj carbon yeej weldability.
4. Qhov ntau thiab tsawg
Pias: Square (shs), duab plaub (RHS), puag ncig (As).
Loj npaum li cas:
Square: OD: 20mm × 20mm - 1200mm × 1200mm WT: 1.2-60mm
Daim Ntawv Sib Tw: Od: 20mm × 30mm - 1200mm × 1500mm WT: 1.2-60mm
Vacular: ERW: 1/2 nti-24inch
LSAWW: 406mm-1420mm
SSAW: 219mm-4020mm
SMLS: 1 / 2inch-1060mm
Kev thev: Tswj hwm los ntawm ASTM A1085 lossis A500 rau qhov ntev, ncaj, thiab suraress.
5. Cov Tseem Ceeb Distintions & Kev Txom Nyem
HRC ≠ ERW:
ERW (hluav taws xob tiv thaiv welded) yog cov txheej txheem siv rau weld lub seam.
HRC yog hais txogKub -} rolled coilCov khoom siv hauv paus.
"HRC" vs. Hardness (Rockwell C):
Kev meej pem ceeb toom: "HRC" ntawm no ≠ rockwell hardness nplai.
A36 vs. A500 / A1085:
A36: Cov qauv txheem (chemistry / lub zog).
A500 / A1085: Cov qauv khoom lag luam rau HSS (kev thev naus laus zis / kev sim).
A36 HRC HSS Raws A36 Cov Khoom Siv A36 Cov Khoom Siv tab sis siv A500 / A1085 rau kev tsim.
6. Cov Ntawv Thov
Cov txheej txheem txheej txheem: Beams, txhua yam hauv cov tuam tsev.
Txhawb cov qauv: Racks, thav ntawv, conveyors.
Kev Tsim Kho: Cov tsheb ciav hlau, rooj tog zaum, kev ua kom zoo nkauj.
Lub tshuab: Thav ntawv, tiv thaiv, cov cuab yeej siv khoom siv.
7. Qhov zoo ntawm A36 HRC hss
Nqi -}}}}: Pheej yig dua li alloy hlau.
Hwj txwv: Cov ntsiab lus carbon qis tiv thaiv kev tawg.
Muaj meej: Yooj yim txiav, drilling, welded.
Kev yuav tau: Dav stocked thoob ntiaj teb.
8. Txwv & txiav txim siab
Kev ua cev tub: Tsis corrosion - tsis kam; yuav tsum tau pleev xim / galvanizing.
Kev txwv lub zog: Tsis haum rau siab - kev siv ntxhov siab (piv txwv li, tawm tsam).
Txias - kev sib haum xeeb: Ua haujlwm hnyav yuav ua rau cov cuab yeej hloov kho me me nyob ze cov ces kaum.
9. Ntawv pov thawj & kev xeem
Zeb Cov Ntawv: Xyuas kom muaj kev sib tw mus rau A36 / A500 / A1085.
Kev Ntsuam Xyuas Tseem Ceeb:
Tensile zog, tawm los lub zog, elongation.
Khoov xeem (rau ductility).
Hydrostatic lossis ultrasonic weld kev ntsuam xyuas.
10. Cov lus qhia tswv yim
Tsim cov hau: Txhim kho kom zoo los ntawm kev txiav txim siab A1085 (muaj zog dua / tawm lub zog).
Qaub: Qhia meej ob qho khoom siv (A36) thiab cov qauv qauv (A500 lossis A1085).
Yam pauv chaw: A500 gr c lossis A1085 muaj kev ua kom muaj zog dua yog tias xav tau.
Ntsiab lus:
ASTM A36 HollC Hollow seem muab cov nqi ntawm cov roj carbon hlau ua tau zoo ntawm cov hlau nrog cov neeg tuaj ntawm no- tsim hss. Nws yog qhov zoo tagnrho rau cov ntawv thov cov kev thov uas xav tau ncaj ncaj Fabrication thiab vuam. Nco ntsoov paub meej tias koj tus neeg xa khoom txhais tau tias "HRC" thiab thov ua raws li ASTM A500 lossis A1085 rau kev sib xyaw ua ke rau cov qauv tsim. Rau kev ua tau zoo dua, tshawb txog 185-raws seem.
