Fabricating Corten steel perforated panels yuav tsum muaj kev sib xyaw ua ke ntawm kev ua kom zoo, cov khoom siv - cov txheej txheem tshwj xeeb, thiab ua tib zoo saib kom meej- tseem ceeb rau kev khaws cov khoom siv tiv thaiv corrosion thiab kev zoo nkauj. Los ntawm kev txiav nkig perforations kom ua tiav cov khoov du thiab txhawb nqa patina, txhua kauj ruam xav tau kev ua raws li Corten cov khoom tshwj xeeb (xws li, alloy muaj pes tsawg leeg, kev ua haujlwm).
Core Fabrication Processes
Txiav Perforations: Laser txiav yog tus qauv kub rau Corten steel (thickness 1-10mm), siv fiber ntau laser (1000-4000W) kom xa ± 0.1mm qhov kam rau ua, cov npoo ntse, thiab cov cua sov tsawg kawg nkaus - thaj chaw cuam tshuam (HAZ)- tiv thaiv warping lossis cov khoom tsis muaj zog. Rau cov vaj huam sib luag tuab (10-25mm), plasma txiav (nrog rau huab cua lossis pa oxygen) tuaj yeem siv tau, txawm tias qhov precision yuav txo qis rau ± 0.5mm. Ob txoj kev xav tau cov ntaub ntawv CAD digital los qhia cov qauv perforation (geometric, kev cai motifs) thiab xyuas kom meej qhov sib txawv (qhov tsawg kawg ntawm qhov chaw nrug=1.5x qhov taub).
Khoov: Corten's ductility sib txawv los ntawm tuab, yog li khoov yuav tsum tau lub vojvoog tuag (tsawg kawg 1.5x cov khoom tuab) kom tsis txhob tawg -tshwj xeeb tshaj yog rau cov vaj huam sib luag loj dua lossis sib npaug li 6 hli. Khoov yuav tsum tau positioned tsawg kawg yog 2x lub qhov taub kom deb ntawm perforation kab kom muaj kev ruaj ntseg zoo; rau cov duab complex, incremental dabtsi yog khoov (10-15℃ib pass) txo kev ntxhov siab. Hydraulic pressbrakes nrog CNC tswj tau pom zoo rau qhov raug, kom ntseeg tau tias cov kaum sab xis ntawm cov vaj huam sib luag loj.
Ua tiav: Kev npaj nto yog qhov tseem ceeb rau kev txhim kho patina. Ua ntej, degrease panels nrog roj av-raws li cov kuab tshuaj (xws li cov ntxhia dej) kom tshem tawm cov roj tsim. Tom ntej no, sandblast nrog 80-120 grit aluminium oxide kom tshem tawm cov nplai zeb thiab tsim kom muaj qhov ntxhib ntxhib ntxhib ntxhib ntxhib los mos- txhawb nqa txawm tias patina adhesion. Rau ua ntej-weathered finishes, panels raug rau tswj cov av noo (80–90%) thiab kub (20–25 degree) rau 1-2 lub lis piam, los yog kho nrog kua qaub-raws li kev daws teeb meem (xws li, phosphoric acid) kom ceev tsim patina. Thaum kawg, yaug nrog dej tshiab thiab huab cua- kom qhuav kom tshem tawm cov khoom seem.
Q: Dab tsi laser txiav tsis ua haujlwm zoo tshaj plaws rau nyias thiab tuab Corten steel?
A: Rau 1-5mm panels: 1000-2000W fiber ntau laser, txiav ceev 3-5m / min, pab roj (nitrogen) los tiv thaiv oxidation. Rau 6-10mm: 3000-4000W laser, ceev 1-2m / min, oxygen pab kom ceev txiav (nrog me ntug oxidation, tshem tau ntawm sandblasting).
Q: Yuav ua li cas kom tsis txhob galvanic corrosion thaum lub sij hawm fabrication?
A: Siv Corten- cov cuab yeej siv tau (stainless hlau lossis Corten tiv tauj qhov chaw) thiab cov khoom txuas (ASTM A485 stainless hlau). Tsis txhob tiv tauj nrog cov cuab yeej carbon steel- cov khoom hlau tuaj yeem ua rau Corten ntog, ua rau tsis sib xws. Ntxuav cov cuab yeej ntawm kev siv los tiv thaiv kev sib kis -.
Q: Corten perforated panels puas tuaj yeem khoov rau hauv cov duab nkhaus?
A: Yog lawm-rau qhov nkhaus me me (lub vojvoog loj dua lossis sib npaug li 500mm), siv lub yob bender nrog cov menyuam roj hmab los tiv thaiv qhov chaw. Rau qhov nkhaus nkhaus, ua kom sov qhov chaw khoov mus rau 300-400℃(tsis txhob tshaj 500 degree, vim nws tsis muaj zog Corten cov khoom siv hlau) thiab siv lub mandrel los tuav lub qhov zoo thaum khoov.
Q: Dab tsi yog qhov siab tshaj plaws vaj huam sib luag rau fabrication yam tsis muaj warping?
A: Optimal vaj huam sib luag loj yog tsawg dua los yog sib npaug rau 3m (ntev) x 1.2m (dav) rau 1-6mm thickness; Cov vaj huam sib luag loj dua tuaj yeem hloov pauv thaum txiav lossis khoov. Rau cov haujlwm loj, tsim cov ntu me me thiab koom nrog Corten- siv cov vuam sib txuas (siv E7018 electrodes) ua raws li sandblasting los muab cov seams.
Q: Yuav ua li cas kom paub meej patina nyob rau hauv tag nrho cov fabricated panels?
A: Ua kom tiav cov txheej txheem tiav: siv tib lub sandblasting grit, degreasing hnyav, thiab ua ntej - huab cua huab cua rau txhua lub vaj huam sib luag. Tsis txhob nthuav tawm ib feem ntawm cov vaj huam sib luag ua tiav rau sab nraum zoov, vim tias qhov tsis sib xws ntawm ya raws / UV raug ua rau tsis sib xws patina. Packing tiav panels nyob rau hauv breathable yas los tiv thaiv los ntawm cov kab mob ua ntej installation.
