Loopers for Long Rolling Mills

Achieve superior tension control with Primetals Technologies loopers for long rolling mills, engineered to maintain precise tension between rolling stands—essential for product quality, mill efficiency, and equipment longevity. By seamlessly regulating tension, they prevent fluctuations that lead to defects, cobbles, and excessive wear on mill components. Designed for single-strand and multi-strand rolling (up to five-strand), the loopers from Primetals provide unmatched precision, reliability, and adaptability to meet the unique demands of the operation.

Loopers for Long Rolling Mills

Loopers from Primetals Technologies feature advanced technology designed to enhance rolling stability while prioritizing safety and ease of maintenance. Equipped with pneumatically actuated persuader arms, jack screw tension adjustments, and optional remote-actuated motors, these loopers enable effortless loop height control and precise tension regulation. This minimizes product scratching, improves yield, and ensures optimal rolling performance.

To boost operational efficiency, reduce operator risk, and simplify maintenance, Primetals Technologies has incorporated lubricated, hinged safety cage doors and remote adjustment capabilities. The robust yet customizable design supports a tension-free, cost-effective rolling process tailored to the specific layout and product mix of each mill. By optimizing tension control, loopers from Primetals Technologies improve product quality, reduce downtime, and enhance overall mill efficiency, helping steel producers achieve superior performance with every pass.
