Project Name: 1450mm color coating production line
Customer Name: Vietnam
Project nature: new construction
Undertaking method: joint contracting
Signing time: April 19, 2010
Production: Under construction
Progress: Good
1. Basic parameters:
1. Material: galvanized steel coil
2. Steel coil weight: Max25t/roll
3. Finished product weight: 5-10t/roll
4. Outer diameter of steel coil: φ900-2100mm
5. Inner diameter of steel coil: φ508/φ610mm
6. Steel plate thickness: 0.2-1.0mm
7. Steel plate width: 800-1250mm
8. Production line design process speed: Max80m/min
9. Energy: steam, water, electricity
10. Roller coating process: two coatings and two drying on the front and back sides continuously
11. The linear speed before and after the inlet loop is max120m/min
12. Color plate coating thickness: the thickness of the front single layer dry film can be adjusted between 8-15μm, and the thickness of the front and back single layer primer dry film can be adjusted between 5-15μm
13. Under the premise that the galvanized substrate complies with the national standard GB2518-88 and the color plate coating thickness and paint index meet the national standard, the color plate coating quality index meets the relevant technical parameters in GB12754/91.
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: 100,000 tons/year (calculated according to the steel plate specification of 1250 mm×0.45mm corresponding to the ****** process speed, 300 working days/year, 24 hours/day).
