Fabricators feem ntau xav tsis thoob uas cov txheej txheem tsim ua haujlwm zoo tshaj plaws rau Q355GNH Corten Steel- siv txoj kev tsis ncaj ncees tuaj yeem ua rau muaj qhov tawg, txo cov tawv nqaij, lossis cuam tshuam corrosion. Raws li qhov siab -kev ua tau zoo Corten Steel nrog kev txhim kho qis- kub ductility thiab nruab nrab lub zog, Q355GNH yog sib xws nrog feem ntau cov txheej txheem hlau tsim, tab sis yuav tsum tau hloov maj mam hloov kho kom zoo, tshwj xeeb tshaj yog rau cov phaj tuab lossis cov duab nyuaj. Yog li, cov txheej txheem tsim twg haum Q355GNH, thiab cov lus qhia tseem ceeb dab tsi ua kom muaj kev sib raug zoo? Raws li kev lag luam tsim kev xyaum thiab cov khoom siv, cov lus teb tseem ceeb yog qhov tseeb:Q355GNH Corten Steel yog qhov zoo- haum rau kev khoov, dov, txiav, thiab xuas nrig ntaus- cov txheej txheem tseem ceeb no ua haujlwm tau zoo nrog kev ceev faj yooj yim, thaum kev sib sau hnyav yuav xav tau preheating. Hauv qab no yog cov lus qhia yooj yim, ua tau zoo.
Qhov Tseem Ceeb: Q355GNH's Formability Advantage
Q355GNH kev sib raug zoo nrog ntau yam txheej txheem tsim los ntawm nws cov kev ua kom zoo dua qub - taug qab Ni thiab Mn ntxiv txhim kho ductility, ua rau nws hloov tau ntau dua li cov qauv Corten qib:
Ductility: Nws elongation tus nqi (Ntau dua los yog sib npaug li 21%) tso cai rau nruab nrab bending thiab dov yam tsis muaj cracking, txawm rau nyias daim hlau (tsawg dua los yog sib npaug rau 10mm).
Tsawg-Tsub Formability: Tswj kev hloov pauv ntawm -20 degree, yog li kev tsim tuaj yeem ua tiav hauv qhov chaw txias yam tsis muaj pob tawg.
Surface Sensitivity: Qhov chaw tsis muaj patinated yog qhov tawv, tab sis zam kev sib txhuam ntau dhau los tiv thaiv khawb uas cuam tshuam kev tsim patina tom qab.
Cov Txheej Txheem Tseem Ceeb rau Q355GNH (Cov Lus Qhia Qhia)
Cov txheej txheem no tau siv dav rau Q355GNH, nrog rau kev hloov me me uas xav tau rau feem ntau cov xwm txheej:
1. Khoov (Cov Txheej Txheem Feem Ntau)
Kev tsim nyog: Zoo tagnrho rau kev tsim cov kaum sab xis, cov kab, lossis cov khoom nkhaus (xws li, guardrails, hniav cladding).
Tswv yim tswv yim: Siv ib tug dabtsi yog khoov vojvoog Ntau tshaj los yog sib npaug zos rau 3 × phaj thickness (Ntau tshaj los yog sib npaug rau 4 × rau thicknesses ＞16mm) kom tsis txhob nto tawg; tsis txhob ntse tuag uas khawb qhov chaw.
Cold vs. Kub dabtsi yog khoov: Txias dabtsi yog khoov ua haujlwm rau daim hlau Tsawg dua lossis sib npaug li 20mm; Kub dabtsi yog khoov (150-200 degree) yog pom zoo rau daim hlau tuab (＞20mm) kom txo tau kev ntxhov siab.
2. Rolling (Rau Curved Shapes)
Kev tsim nyog: Zoo meej rau kev tsim cov cylindrical lossis 弧形 cov khoom (xws li, cov yeeb nkab txhawb nqa, nkhaus cladding).
Tswv yim tswv yim: Siv peb lub - yob dabtsi yog khoov tshuab kom haum siab; dov maj mam kom tsis txhob deformation tsis sib xws -tshwj xeeb tshaj yog rau cov phaj tuab (10-40mm).
Ncej - Rolling: Tsis xav tau kev kho cua sov; Tsuas yog tshawb xyuas qhov khawb ntawm qhov chaw thiab du lawv maj mam yog tias muaj.
3. Txiav (Pre-Fabrication Step)
Txoj Kev Pom Zoo: Laser txiav (zoo tshaj plaws rau kev txiav txim siab, daim hlau nyias tsawg dua lossis sib npaug li 12 hli), plasma txiav (rau cov phaj tuab ＞ 12 hli), thiab shearing (rau kev txiav ncaj ntawm daim hlau nyias tsawg dua lossis sib npaug li 8 hli).
Tswv yim tswv yim: Tsis txhob oxy- txiav acetylene yog tias ua tau- nws tawm ntawm ntug ntxhib uas yuav tsum tau sib tsoo; ntxuav cov npoo kom tshem tawm slag ua ntej sib sau ua ke.
4. Punching (Rau qhov thiab qhib)
Kev tsim nyog: Siv los tsim cov qhov hauv cov khoom siv (piv txwv li, ntsia liaj qhov rooj qhov rau thav duab, guardrails).
Tswv yim tswv yim: Siv cov xuas nrig ntaus thiab tuag; lub qhov taub yuav tsum siab dua los yog sib npaug rau 1.5 × phaj thickness los tiv thaiv ntug tawg; punch maj mam rau cov phaj tuab (＞ 10mm).
Cov txheej txheem kom zam los yog siv ceev faj
Kev kos duab sib sib zog nqus: Q355GNH's ductility tsis zoo tagnrho rau kev kos duab sib sib zog nqus (xws li, tsim cov khob nyuaj lossis plhaub)- nws tuaj yeem tawg thaum lub sijhawm ua haujlwm; siv qhov tshwj xeeb sib sib zog nqus- kos duab hlau hloov.
Extrusion: Kub extrusion yog ua tau tab sis yuav tsum muaj qhov kub thiab txias thiab cov cuab yeej tshwj xeeb - tsuas yog siv rau cov khoom siv tuab nrog kev taw qhia kev tshaj lij.
Tseem ceeb tsim yuam kev kom zam
Siv lub vojvoog me me dhau lawm: Ua rau cov kab tawg thiab ua rau cov hlau tsis muaj zog.
Kev tsim yam tsis muaj kev ntxuav: Cov plua plav, roj, lossis xeb xoob ntawm qhov chaw ua rau khawb thiab deformation tsis sib xws.
Kev sib sau nrawm: nrawm nrawm / dov ua rau muaj kev ntxhov siab ntau dhau, ua rau muaj kev pheej hmoo ntawm kev tawg, tshwj xeeb tshaj yog rau cov phaj tuab.
Hauv cov ntsiab lus, Q355GNH Corten Steel yog qhov sib xws nrog kev khoov, dov, txiav, thiab xuas nrig ntaus - cov txheej txheem tseem ceeb no ua haujlwm tau zoo nrog kev ceev faj yooj yim. Los ntawm kev sib piv cov txheej txheem rau koj cov phaj tuab thiab cov khoom zoo, koj tuaj yeem ua kom cov ntaub du, khaws cov hlau ua haujlwm, thiab ua kom nws lub neej ua haujlwm siab tshaj plaws hauv kev siv zaum kawg.
