Tandemvaltsimine

Tandemvaltsimine, also known as tandem rolling, is a metalworking process where two rolling mills are connected in series. This allows for the simultaneous reduction of material thickness in a single pass. The metal workpiece passes through the first mill, where it is reduced in thickness, and then immediately enters the second mill, where it is further reduced. This setup is particularly useful for achieving significant reductions in a controlled manner or for processes that require multiple stages of rolling with minimal handling between stages.

The primary advantage of tandem rolling is increased productivity. By performing multiple reductions sequentially, the overall processing time is significantly reduced compared to using individual rolling mills. This also leads to improved consistency in the final product's thickness and properties, as the material is not subjected to cooling or handling between the rolling stages. Tandem rolling is commonly employed in the production of thin metal sheets and foils, such as those used in packaging, electronics, and automotive components. The design of a tandem rolling mill requires precise alignment and synchronization of the individual mills to ensure optimal performance and product quality. Specialized control systems are often implemented to manage the tension and speed of the material as it moves between the rolling stands.
