Fabricators, designers, thiab project managers feem ntau ua qhov tseem ceeb ntawm cov khoom siv ua haujlwm tau zoo -tshwj xeeb tshaj yog thaum ua haujlwm rau kev cai sab nraum zoov lossis cov haujlwm ua haujlwm. Q310NH Corten Steel yog qhov nrov nruab nrab- txoj haujlwm xaiv (yield Ntau dua lossis sib npaug rau 310MPa), tab sis ntau tus xav tsis thoob yog tias nws lub zog thiab corrosion kuj tuaj ntawm tus nqi ntawm kev nyuaj rau vuam lossis daim ntawv. Nws puas tuaj yeem yooj yim zoo li tus qauv tsim? Puas yog vuam xav tau kev txawj tshwj xeeb lossis khoom siv? Lub ntsiab lus teb yog qhov tseeb:Q310NH Corten Steel yog ib qho yooj yim rau vuam thiab tsim, tshwj xeeb tshaj yog rau lub teeb - mus rau - nruab nrab thicknesses - nws cov ductility thiab weldability ua rau nws siv tau rau cov txheej txheem fabrication, nrog rau cov lus qhia me me los xyuas kom meej qhov zoo.. Hauv qab no yog cov lus qhia yooj yim, cov tswv yim.
Weldability ntawm Q310NH Corten Steel (Yooj Yim & Siv tau)
Q310NH yog tsim los rau kev yooj yim ntawm vuam, sib xws nrog cov txheej txheem siv rau cov zoo tib yam thiab Corten Steels - tsis muaj cov cuab yeej tshwj xeeb xav tau:
Tau tshaj Vuam Txoj Kev: Ua haujlwm zoo nrog cov txheej txheem ntau: arc vuam (SMAW), MIG vuam (GMAW), thiab TIG vuam (GTAW). Cov no tau siv dav hauv khw muag khoom, ua Q310NH yooj yim ua haujlwm nrog rau feem ntau pab pawg.
Preheating yuav tsum tau: Rau cov phaj nyias (＜20mm), tsis xav tau preheating -txuag lub sijhawm thiab kev ua haujlwm. Rau cov phaj tuab (20-40mm), lub teeb preheat (80-100 degree) pab tiv thaiv kab mob khaub thuas, tshwj xeeb tshaj yog nyob rau hauv qhov chaw txias.
Weld Quality Tip: Siv Corten- siv vuam electrodes (piv txwv li, E7018 rau arc vuam) kom phim cov hlau tsis muaj zog corrosion- xyuas kom cov welds tsim tib yam kev tiv thaiv patina raws li cov khoom siv hauv paus, zam cov ntsiab lus tsis muaj zog.
Formability ntawm Q310NH Corten Steel (Flexible rau Custom Designs)
Nws qhov nruab nrab - lub luag haujlwm lub zog tsis cuam tshuam qhov yooj yim ntawm -Q310NH tuaj yeem ua rau ntau hom, zoo tagnrho rau cov haujlwm kev cai:
Tsim cov txheej txheem tsim: Yooj yim khoov, folded, dov, thiab xuas nrig ntaus. Nws yog qhov zoo tshaj plaws rau nkhaus facades, hniav panels, guardrails, thiab kev cai vaj vaj tse.
Thickness cuam tshuam: Nyias daim hlau (3-15mm) yog ib qho yooj yim heev rau daim ntawv - tuaj yeem khoov nrog cov qauv ntawv los yog hydraulic benders. Cov phaj tuab (15–40mm) yuav tsum muaj zog ntau dua tab sis tseem ua haujlwm tau nrog cov khoom siv hnyav -.
Tsim Kev Ua Zoo Tshaj Plaws: Ua kom muaj qhov tsawg kawg nkaus khoov vojvoog (Ntau dua lossis sib npaug ntawm 2.5x phaj tuab) kom tsis txhob muaj qhov tawg. Slow forming speeds txo kev ntxhov siab, khaws cia cov hlau kev ruaj ntseg thiab corrosion kuj.
Cov lus qhia tseem ceeb kom tsis txhob vuam / tsim qhov tsis xws luag
Ua raws li cov kauj ruam yooj yim no hauv siab kom ntseeg tau tias kev tsim khoom du thiab siab - tau zoo:
Ntxuav lub ntsej muag ua ntej: Tshem tawm cov av, roj, los yog xeb xeb ua ntej vuam / tsim- cov kab mob tuaj yeem ua rau cov vuam tsis sib xws lossis qhov chaw puas.
Tsis txhob overheating: Tshaj 150℃thaum preheating lossis vuam tuaj yeem ua rau Q310NH lub zog tawm los thiab cuam tshuam rau kev tsim patina.
Tom qab-weld tu: Rau cov haujlwm tseem ceeb, maj mam txhuam cov welds kom du du -pab patina daim ntawv sib npaug ntawm tag nrho cov khoom.
Yuav ua li cas Q310NH piv rau lwm yam Corten Steels
Rau cov ntsiab lus, Q310NH yooj yim dua rau vuam thiab tsim dua siab dua - lub zog Corten variants (xws li, Q355GNH), uas yuav tsum tau ua kom sov dua thiab cov khoom hnyav dua. Nws yog me ntsis hloov tau yooj yim dua li lub teeb-lub luag haujlwm Q265GNH tab sis muaj zog ntau dua- tawm tsam qhov sib npaug zoo rau feem ntau cov haujlwm tsim khoom.
Hauv luv luv, Q310NH Corten Steel yog ib qho yooj yim rau welding thiab daim ntawv, ua rau nws yog ib tug tswv yim xaiv rau kev cai sab nraum zoov thiab structural tej yaam num. Nws compatibility nrog tus qauv fabrication txoj kev thiab yooj rau shaping kom ib tug du txheej txheem, txawm rau pab pawg uas tsis muaj kev txawj ntse tshwj xeeb.
