A special feature of tinplate production is the second rolling step for thickness reduction after annealing. Running parallel to this is a temper rolling process that prepares the strip for further surface finishing and coating. Our twinstand double cold reduction mills (DCR) combine reduction rolling and skinpassing in a single mill.
