Coupled pickling lines and tandem cold mills High-capacity production for high-quality products Example of Siemens VAI coupled pickling line... Pickling lines and tandem cold mills For a wide range of product applications, the required strip thickness, flatness and surface quality can be achieved more economically by linking the pickling and cold rolling processes. This delivers significant improvements with regard to mill productivity, yield and production cost savings as a result of the elimination of strip threading and tailing-out operations. Reduced strip-head and tailend losses also contribute to better overall yield. Our speed optimization system ensures maximum throughput rates under all operating conditions, and maintenance, roll consumption and manpower requirements are also lowered. Typical production capacities of such combined facilities are in the range of 1.2-2 million t/a. Pickling line Pickling lines supplied by Siemens VAI are characterized by high pickling rates, lowcost pickling operations, flexible production, a wide range of product sizes, qualities, reliable plant operation, and low maintenance requirements, as well as compliance the highest standards for environmental safety. The pickling model – SIROLL CIS Faplac® The SIROLL CIS Faplac® system (Fully Automatic Pickle Liquor Analysis and Control) ensures an efficient operation of the pickling process by compliance of a proper acid and iron concentration (waste acid). The employment of roll and strip temperature models ensures the achievement of tight tempera ture tolerances and the avoidance of overheating thus prolonging the life of the emulsion. In addition the rolling strategies calculated by the process models are geared to the minimum use of electrical energy by making the most efficient use of the mill with respect to roll force, roll torque and roll power. Main benefits: High pickling throughput rates Uniformly pickled surfaces Closed loops of acid, fume and rinse circulation reduce operation cost in an environmental-friendly manner 10
... and tandem cold mill Coupling devices Siemens VAI installs helical turning devices or turning towers for coupling existing sections or new and existing sections for a pickling line tandem cold mill configuration. With these solutions it is possible to change the direction of the strip and build a line, such as a 90° configuration, if the layout requires such a strip turning.
