Key features
-
Combination of two kinds of lines: continuous processing line and tandem cold rolling mill, picking section operates continuously, tandem discontinuously
-
The lines are connected to one another by a material looper (coupling looper).
-
Increased requirements for tracking and ibaQDR synchronization if “uncoupled operation” is also possible.
-
1:n, n:1 and n:m production possible.
-
Multiple products in the line simultaneously
-
Scrap cuts, sample cuts
-
Significant material elongation in tandem section
Typical measured values
Thickness, width, bath temperature, concentration/pH value, strip tension, rolling forces

Example:
In the following figure, the first graph shows the last thickness measurement signal from a pickling tandem line transformed to the finished strip length (standard behavior of ibaQDR). As the length signal from the measuring location at the tracking start is available (second graph), the XY function from ibaAnalyzer can be used to perform a transformation to the entry length (third graph). For the sake of completeness, in the last graph the signal has then been shifted to the left to the origin.
