2. Unit Output: 120,000 tons/year  

3. Energy Sources: Water, electricity, natural gas  

4. Roll Coating Process: Continuous two-coat two-bake for front and back surfaces  

5. Color Coating Thickness: The dry film thickness of the top coat can be adjusted between 5-20μm; the dry film thickness of the primer can be adjusted between 3-10μm  

6. Layer Misalignment Deviation in Width Direction of Color Coil: Single side ≤±1.0mm  

7. On the premise that the galvanized substrate complies with national standard GB/T2518-2004 and the coating thickness and paint indicators of color plates meet national standards, the quality indicators of color plate coating comply with relevant technical parameters in GB/T 12754-2006.  

8. Production Line Direction: From right to left when viewed from the operation side  

III. Basic Process Flow  

The main equipment is composed in sequence as follows:  

Manual Feeding → Uncoiling Unit I, Ⅱ → Uncoiling Pinch Machine I, Ⅱ → Shearing Machine I, Ⅱ → Converging Pinch Machine → Riveting Machine → Flattening Roll → Tension I (Four-roll) → Entry Looper → Centering Mechanism I → Tension Machine Ⅱ (S-roll) → Squeezer I → Pre-degreasing → Roller Brushing Machine I → Squeezer Ⅱ → Degreasing → Roller Brushing Machine Ⅱ → Squeezer Ⅲ, Ⅳ → Water Washing I → Squeezer Ⅴ → Water Washing Ⅱ → Squeezer Ⅵ → Water Washing Ⅲ → Squeezer Ⅶ, Ⅷ → Hot Air Blowing Device I → Chemical Coating Machine → Steam Drying Oven → Forced Air Cooling Device 1 → Centering Mechanism Ⅱ → Tension Machine Ⅲ (S-roll) → Primer Roll Coater → Primer Leveling → Primer Curing Oven → Forced Air Cooling Device 2 → Primer Intensive Cooling Chamber (Water Cooling) → Squeezing Centering Machine I → Hot Air Blowing Device Ⅱ → Tension Machine Ⅳ (S-roll) → Single-roll Centering Machine → Deflector Roll → Top Coat Roll Coater 1.2 → Top Coat Leveling → Top Coat Curing Oven → Forced Air Cooling Device Ⅲ → Top Coat Intensive Cooling Chamber (Water Cooling) → Squeezing Centering Machine Ⅱ → Hot Air Blowing Device Ⅲ → Tension Machine Ⅴ (Four-roll) → Exit Looper → Centering Mechanism Ⅵ → Tension Machine Ⅵ (S-roll) → Pinch Shear Ⅲ → Coiling Pinch Machine → Servo Coiling Unit → Manual Unloading (equipped with belt coil assistor).
