    A tandem rolling mill is a rolling mill with two or more close coupled stands where the reduction is achieved by the inter stand tension s and the compressive force between the work rolls.. For mills rolling thinner strip bridles may be added either at the entry and/or the exit to increase the strip tension near the adjacent stands further increasing their reduction capability.
