Coil Slitting Line Production Process

A coil slitting line is essential for transforming wide steel coils into narrower coils, tailored to specific dimensional and quality requirements. This specialized equipment seamlessly integrates various stages—uncoiling, slitting, and recoiling—to ensure precision and efficiency in the production process. Comprising components like the uncoiler, slitter, tension machine, and re-coiler, supported by units for feeding, guiding, and conveying, the coil slitting line excels in processing CR coil, galvanized coil, and color coil materials.
