Innovative Pickling section complete with:

• shallow-type and high-agitation pickling tanks
• multi-cascade system of Hydrochloric Acid & rinsing system
• accurate control of acids, effluents and fumes

The lines are equipped with simple but state-of-the-art automation providing for on-line acid control and with a Tension Leveler/Scale Breaker for more efficient pickling and strip shape improving.

In order to meet all customer and product needs Tenova is able to combine push-pull and semi-continuous pickling lines into one solution called WRPL (Wide Range Pickling Line). Such solution optimises the advantages of the two line types providing high productivity and pickled quality for both thin and thick gauges. In push-pull mode the line satisfies requirements for high strip thickness and strength ranges.

The strip passes from uncoiling sections directly to the process tanks and then to the trimming machine and the tension reel without passing through the looper and relevant bridles (as in conventional push-pull lines). For thinner gauges the line is used in semi-continuous mode and coil ends are joined by a stitcher without stopping the strip in the process section thanks to a horizontal looper.
