Production Line Working Process

Decoiling → Feeding → Leveling → Head Cutting → Guiding → Slitting → Scrap Collecting → Damping → Recoiling

During operation, each section works in coordination to ensure smooth material flow. First, the decoiler releases the steel coil steadily. Then, the leveling and guiding systems correct flatness and alignment. Finally, the slitting and recoiling units actively maintain strip tension, producing neat and uniform finished coils.
