Undertaking method: Jingjie Ruisi general contracting
Signing time: April 25, 2010
Production: Under construction
Progress: Good
1. Basic parameters:
1. Material: galvanized steel sheet, aluminum-zinc sheet coil (including FH, yield strength <600MPa)
2. Steel coil weight: Max20t/roll
3. Finished product weight: Max10t/roll
4. Outer diameter of steel coil: raw material φ508-2000mm
The finished product φ508-1250mm
5. Inner diameter of raw steel coil: φ508/φ610mm
Inner diameter of finished steel coil: φ508/φ610mm
6. Steel plate thickness: 0.2-1.2mm
7. Steel plate width: 600-1250mm
8. Production line design process speed: 100m/min (transmission speed Max120 m/min)
9. Energy: water, electricity, natural gas
10. Roller coating process: two coatings and two drying on the front and back sides continuously
11. The linear speed before the inlet loop and after the outlet loop is 15-150m/min
12. Color board coating thickness: the thickness of the dry film of the top coat can be adjusted between 8-15μm, and the thickness of the dry film of the primer can be adjusted between 5-12μm
13. Under the premise that the galvanized substrate complies with the national standard GB/T2518-2004 and the color plate coating thickness and paint index meet the national standards, the color plate coating quality index meets the relevant technical parameters in GB/T 12754-2006.
14. The width direction of the color plate roll is deviated from the deviation of the layer on one side≤± 1.0mm
15. Production program: 120,000 tons/year (according to the ****** process speed corresponding to the steel plate specification 1000 mm×0.4mm, calculated at 100 m/min, 300 working days/year).
16. Production line direction: from left to right from the operation side
