Taw qhia
Corten Qib A steel phaj, kuj huCorten steel phajlos yoghuab cua steel, yog dav siv nyob rau hauv txuas hniav, architectural facades, thiab industrial lug rau nws ua ke ntawm durability thiab corrosion kuj.
Raws li ib tugxeb-resistant steel phaj, kev vuam thiab kev tsim khoom tsim nyog yog qhov tseem ceeb los tswj nws cov khoom siv kho tshuab thiab ntev - lub sij hawm patina tsim.
1. Cov txheej txheem vuam
| Txoj kev | Siv Thickness | Qhov zoo | Sau ntawv |
|---|---|---|---|
| SMAW (Shielded Hlau Arc Vuam) | 6-25 hli | Portable, teb -tus phooj ywg | Siv tsawg-hydrogen electrodes los txo qhov tawg |
| GMAW (MIG Welding) | 2-20 hli | Ntxuav welds, siab deposition npaum li cas | CO₂/Ar shielding gas pom zoo |
| FCAW (Flux{0}}Cored Arc Vuam) | 4-25 hli | High productivity | Xaiv cov flux sib xws nrog Corten alloy |
| SAW (Submerged Arc Welding) | >10 mm | Ua haujlwm zoo rau cov phaj tuab | Preheat tej zaum yuav xav tau los tiv thaiv micro- tawg |
Kev soj ntsuam:Kev tuav cov cua kub tsawg yog qhov tseem ceeb rau kev khaws ciahuab cua steelcov khoom hauv weld aav.
2. Welding Parameters
Preheating: For plates >20 hli, preheat rau 100-150℃kom txo cov kev ntxhov siab seem.
Interpass Kub:Khaws qis dua 300℃kom tsis txhob muaj cov qoob loo ntau dhau.
Electrodes:Siv Ni-Cu alloy electrodes los xyuas kom meej corrosion-welds resistant.
Thaum tshav kub kub input Control:Pom zoo <2 kJ/mm rau kev pom lub zog thiab kev txuag patina.
Cov ntaub ntawv ua haujlwm:
Welds khaws cia90-95% ntawm lub hauv paus hlau yield zograu Corten Qib A steel daim hlau.
Patina tsim nyob rau hauv weld aav yog me ntsis sai dua pib tab sis stabilizes nyob rau hauv 6-12 lub hlis.
3. Cov Lus Qhia Fabrication
| Txheej txheem | Kev xyaum zoo tshaj plaws | Sau ntawv |
|---|---|---|
| Khoov | Yam tsawg kawg nkaus hauv vojvoog=1.5 × phaj thickness | Tiv thaiv kev tawg |
| Txiav | Cov hniav ntse; zam burrs | Burrs tuaj yeem ua kom muaj zog hauv zos corrosion |
| Drilling / Punching | Siv cov khoom coated; nruab nrab ceev | Txo cov cua sov thiab tiv thaiv corrosion |
| Rolling | Tswj ceev thiab kub | Ua kom flatness thiab txo cov kev ntxhov siab seem |
Kev pom zoo:Kev tsim kho kom raug tuav cov txheej txheem thiab kev zoo nkauj ntawmxeb-resistant steel daim hlau.
4. Tshaj tawm -Kev txiav txim siab ntawm Fabrication
Patina Development:Weld aav thiab txiav npoo yuav tsim xeb sai dua; natural patina evens tawm lub sijhawm.
Tsis xav tau txheej:Tsis txhob pleev xim los yog sealants tso cai rau cov txheej txheem corrosion ntawm ntuj tsim.
Kev tshuaj xyuas:Kev kuaj pom ib ntus kom paub meej txawm tias patina thiab kev ncaj ncees ntawm cov qauv.
5. Cov lus xaus
Corten Qib A steel phaj / Corten steel phaj / weathering steel / xeb -resistant steel phajyuav tsum tau ua tib zoo vuam thiab fabrication rau kev ua tau zoo.
Siv cov khoom siv hluav taws xob kom zoo, tswj cov khoom siv hluav taws xob, thiab ua raws li cov lus qhia khoov / tho kev khaws cia lub zog thiab kev tiv thaiv corrosion.
Cov txheej txheem raug ua kom ruaj khov, zoo nkauj txaus nyiam, thiabqis- steel tucov qauv tsim nyog rau kev txuas hniav, architecture, thiab kev siv hauv kev lag luam.
