Crucial for large production volumes is a continuous production flow. Further benefits are smooth production flow, reduced roll wear, high yield, and consistent, reproducible product quality. What defines the continuous tandem mill (CTCM) is a continuous entry section featuring a pay-off unit, welding machine, and strip accumulator. All this is necessary to ensure an uninterrupted production flow. Typical exit-side installations are also here the drum shear, as well as a double or carousel reel and the inspection unit "Rotary Inspect".
