galvanized steel kauj
Nrhiav kev ntseeg siab S550GD galvanized steel kauj manufacturers hauv Suav teb? Koj twb tuaj rau qhov zoo lawm. Raws li lub Hoobkas ncaj qha nrog 20 xyoo ntawm kev tsim steel hlau, GNEE Steel khoom siv EN 10346 rawsS550GD galvanized steel kaujntawm Hoobkas nqi. Hauv phau ntawv qhia no, peb yuav piav qhia txog cov txheej txheem tsim khoom thiab pab koj nkag siab txog kev tswj xyuas zoo rau koj cov haujlwm.
Galvanized steel yog hlau coated nrog zinc los tiv thaiv corrosion. Nws yog dav siv hauv kev tsim kho, tsheb, thiab hluav taws xob kev lag luam. Cov qib feem ntau suav nrog DX51D (kev siv dav dav), S350GD (lub zog nruab nrab), thiab S550GD (lub zog siab), txhua qhov tshwj xeeb yuav tsum tau ua.

Raw Khoom Npaj rau S550GD Coils
Thawj kauj ruam hauv S550GD ntau lawm yog xaiv cov khoom zoo - zoo raw khoom.
- Base Hlau: Tsawg- carbon steel nrog cov tshuaj muaj pes tsawg leeg (1.0531 cov qauv khoom)
- Zinc Ingot: High-purity zinc (99.995% ntshiab) los xyuas kom meej txheej zoo
- Alloy Additives: Manganese, silicon, thiab txhuas kom tau raws li S550GD txhua yam khoom
Hauv qab no yog cov tshuaj muaj pes tsawg leeg rau S550GD puag steel:
| Element | Cov ntsiab lus (Max.%) | Lub luag haujlwm |
|---|---|---|
| C | 0.12 | Txhim kho lub zog |
| Si | 0.50 | Txhim kho oxidation tsis kam |
| Mn | 1.60 | Boosts lub zog tensile |
| P | 0.030 | Tiv thaiv kom txias brittleness |
| S | 0.025 | Txo kub tawg |
| Al | Ntau dua lossis sib npaug rau 0.015 | Refines grain qauv |
Kub Rolling txheej txheem rau S550GD hlau
Kub dov transforms raw steel rau hauv thawj kauj daim ntawv rau S550GD ntau lawm.
Cua sov: Steel billets rhuab mus rau 1200-1250℃nyob rau hauv ib tug taug kev beam rauv
Rough Rolling: Txo qhov tuab tuab rau 20-30mm ntawm roughing sawv
Ua kom tiav Rolling: Ntxiv txo rau 2.0-6.0mm thickness nrog precision yob
Txias: Tswj cua txias (500-600 degree) kom ua tiav qhov xav tau microstructure
Coiling: Winding rau hauv kub -rolled coils (1.5-3.0 tons) rau cov txheej txheem tom ntej
Txias Rolling thiab Annealing rau S550GD
Txias dov thiab annealing refine steel rau galvanizing.
- Txias Rolling: Txo kub- dov coil thickness kom kawg 0.8-2.0mm nrog txias yob
- Annealing: Cua sov rau 700-800℃nyob rau hauv ib tug nruam annealing rauv rau:
Soften cov hlau rau formability
Txhim kho cov khoom siv kho tshuab
Tshem tawm cov kev ntxhov siab sab hauv
- Daim tawv nqaij hla Rolling: Lub teeb dov (1-3% txo) txhawm rau txhim kho qhov chaw tiav
Kub-Dip Galvanizing txheej txheem rau S550GD Coils
Cov kauj ruam tseem ceeb uas muabS550GD galvanized steel kaujnws corrosion kuj.
- Degreasing: Tshem tawm cov roj thiab cov khoom paug nrog cov tshuaj alkaline (50-60 degree)
- PicklingDescaling nrog hydrochloric acid (18-22% concentration)
- Fluxing: Siv zinc ammonium chloride tov los tiv thaiv oxidation
- Galvanizing: Muab tso rau hauv molten zinc da dej (450-460 degree) rau 3-5 vib nas this
- Cua Knifing: Tswj zinc txheej thickness (60-275g/m²) nrog cua siab
- Txias: Dej txias rau chav tsev kub kom solidify zinc txheej
