Our offline skin-pass mills for carbon steels are stand-alone rolling plants. They usually follow the batch-annealing stage and offer high versatility for processing both hard and ultra-mild strip. The 4-high stands accommodate work rolls in various diameters to apply different rolling forces. That enables production of a wide range of products. Smaller work roll diameters reduce the rolling force when skin-passing high-strength steel strip. Larger work rolls are ideal for processing very mild steel grades with a high rolling force. This not only improves surface roughness but also extends the work roll lifetime. Alternatively, you can choose SPMs in 6-high design for particularly challenging tasks.
