Two new ways to reduce the edge drop are being investigated both theoretically and in rolling trials. The edge drop control cooling system (EDC cooling) produces a crown shape with the aid of three cooling beams arranged on stand‐exit side that, on the one hand, feature a very fine spray pattern distribution in the strip edge area and, on the other hand, are applied with differently tempered cooling medium, allowing the edge drop to be reduced. The EDC rolls are more flexible in the strip edge area than in the remaining part of the barrel. The thus created heavier flattening is, on the one hand, sufficiently large and, on the other hand, also excellently suited by its characteristic property to compensate the edge drop. The effects of both systems were evidenced during comprehensive rolling trials in the first stand of a 2‐stand DCR cold tandem mill. For these trials 52 coils of annealed tin plate were used. With the aid of the EDC system, the strip thickness in the immediate strip edge area could be increased by up to 4% of the nominal thickness.
