1. Cov Khoom Siv Khoom Raw
Hlau Chev / Sawb Xaiv:
Feem ntau siv tsawg -} cov hlau (qib nyiam Q195, Q235 lossis A335 lossis A335 lossis A36)
Dav thiab tuab txiav txim siab los ntawm cov yeeb nkab kawg
Nto yuav tsum yog huv thiab tsis muaj xeb / paug
2. Yeeb nkab tswj
Uncoiling: Steel chev yog pub rau hauv cov kab ntau lawm
Leving: Dhau los ntawm kev tswj cov chais kom tshem kom tshem tawm coil curvature
Kev sib sau: Kev ua kom nruj dhau los ntawm yob txoj kev sib tw sawv ntsug rau hauv ib puag kab hla {}}}}}}}}}}}}}}}}}}}}}
Vuam:
Siab - zaus induction induction induction induction (HFIW) feem ntau
Welds ntawm 1000-1300 Degree tsis muaj tub lim hlau
Weld Seam yog tam sim ntawd cua sov -}} kho rau cov qauv qub
3. Sizing & txiav
Sizing yob: Lub taub tsib lub taub uas muaj qhov tsis raug: 0.5mm)
Txiav:
Flying pom kev txiav cov kav dej yuav tsum tau ntev (feem ntau 6m qauv)
Tuaj yeem tsim kev cai ntev li ntev tau
4. Nto npaj rau galvanizing
Ncab: Alkaline Da Dej Tshem Tawm Roj
Pickling: Hydrochloric / sulfuric acid da dej (15-20% concentration) tshem tawm oxides
Yws: Zinc ammonium chloride daim ntawv thov los tiv thaiv rov - oxidation
5. Kub - dip galvanizing
Galvanizing da dej:
Molten zinc ntawm 445-465℃(ntshiab zinc lossis zn-0.2% al alloy)
Lub sijhawm nqus dej kawm tiav 30-60 vib nas this nyob ntawm Thickness
Cua rab:
High - Siab} Siab Cua Jets Tswj Zinc Txheej Thickness
Raug txheej: 50-600 g / m² (Z60-z600)
6. Post - kev kho
Cua txias: Dej quenching lossis cua txias
Passivation: Chromate lossis tsis - chromate kev kho kom tiv thaiv kom dawb
Kev kuaj xyuas: Txheej thickness ntsuas ntsuas (cov koob yees duab sib nqus) thiab cov tshev pom
7. Ua haujlwm tiav
Ncaj: Rashary straightener ensures qhov tseeb qhov tseeb
Hydrostatic Kuaj: Kev ntsuam xyuas siab rau kev txi -} ntawv pov thawj
Kawg ntsib: Square - txiav lossis beveled xaus raws li yuav tsum tau ua
Thi: Rau cov kav dej (xaiv tau)
8. Tswjhwm & ntim khoom
Kev kuaj:
Txheej Txheej (Rauj Kev Xeem)
Zinc Thickness (Sib Nqus Induction)
Kev Ntsuam Xyuas Sab
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab (Tensile, Zeev Zeev Ntsuas)
Kev cim: Stamped nrog loj, qib, txheem
Ntim: Bundled nrog steel straps, yas kaus mom nyob rau xaus
Cov Qauv Tseem Ceeb
ASTM A53: Cov Qauv Qhia Tshwj Xeeb rau Galvanized Cov Yeeb Nkab
BS 1387: British tus qauv rau cov kav xa ntawv
AS 10240: European Txuj Ci rau kub - dip galvanizing
JIS G3442: Japanese muaj cov qauv muaj kev lag luam
Muaj peev xwm ntau lawm
Cov kab ceev ceev: 20-60 m / min
Cov diam uas ua diameters: 1/2 "txog 8" (15-200mm)
Phab Ntsa Thickness: 1.0-6.0 hli
