Cold-Rolled Coil Production Process
Raw Material Preparation: Hot-rolled steel coils are uncoiled, straightened, and welded at the ends to form a continuous steel strip.
Pickling: Surface scale is removed using hydrochloric acid; after rinsing and drying, the strip is trimmed to the specified width.
Cold Rolling: A multi-stand continuous rolling mill reduces the strip thickness to the target dimension, inducing work hardening.
Degreasing and Cleaning: Rolling oils are removed from the surface via electrolytic degreasing and brushing to prevent sticking during annealing.
Annealing: The strip is heated to the recrystallization temperature in a protective atmosphere to eliminate work hardening and restore plasticity.
Leveling: Light rolling improves flatness, eliminates yield plateaus, and controls surface roughness.
Finishing and Oil Application: After rewinding, slitting, and surface inspection, anti-rust oil is applied to protect the finished product.
Packaging and Storage: The product is weighed, bundled, packaged, and then stored.
FAQ
Q: Is ST12 hot-rolled or cold-rolled? What are its characteristics?
A: ST12 is a cold-rolled steel sheet. Compared to hot-rolled sheets, it offers the following advantages: high surface finish, no scale, high dimensional accuracy, tight thickness tolerances (±0.03–0.05 mm), stable mechanical properties, and good workability. It can be used directly for surface treatments such as electroplating and powder coating.
Q: What are the standard specifications?
A: Standard specifications: Thickness: 0.3 mm to 3.0 mm (common: 0.5, 0.8, 1.0, 1.2, 1.5, 2.0, 2.5, 3.0 mm); Width: 600 mm to 1500 mm (common: 1000, 1250, 1500 mm).
Q: What is ST12 used for?
A: ST12 is a basic commercial-grade cold-rolled steel.
Q: What are the available delivery conditions?
A: Common delivery conditions:
Cold-rolled hard condition (1B): Work-hardened condition with high strength
Annealed soft condition (SD/SB): Annealed in a bell annealing furnace, with reduced yield strength and improved ductility, suitable for further processing
