VEM Coiler Drives for Controlled Winding and Unwinding in Rolling Mills

When metal strip needs to be wound evenly after rolling, the drive system determines strip tension, coil quality and process stability. VEM supplies electric coiler drives and coordinated system solutions for coilers, uncoilers and demanding lines in the metals industry.

What Are Coiler Drives Used For?

Coilers are used in hot rolling mills, cold rolling mills and downstream processing lines. They wind steel or metal strip in a controlled manner, keep strip tension stable and support consistent coil formation. The drive technology must reliably handle high torque levels, changing loads and precise speed specifications.

Drive Technology for Constant Strip Tension

VEM designs coiler drives so that speed, torque and process requirements are precisely aligned. Especially during acceleration, braking and changes in coil diameter, finely tuned control is essential. This helps prevent strip breaks, protect surface quality and reduce downtime.

Robust Solutions for Rolling Mill Conditions

Rolling mill equipment is exposed to heat, dust, vibration and high mechanical loads. VEM drives are engineered for this environment and designed for reliable operation in continuous production processes. Depending on the application, motors, converters and automation interfaces can be combined individually.

Modernization and New Installations

VEM coiler drives are suitable for both new production lines and retrofit projects. Modernization projects often focus on making existing systems more efficient, easier to control and less maintenance-intensive without rebuilding the entire line.

Typical Requirements

high starting and braking torque

FAQ:

What is a coiler drive?

A coiler drive powers coiling or uncoiling equipment in rolling mills. It ensures that metal strip is wound at a controlled speed and with constant strip tension.
