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.

Value for Money
- Requirement of less personnel
- Reduced operating and production costs
Efficiency
- Minimized overall consumption
- Maximum benefit in combination with an acid management system and a dedicated Acid Regeneration Plant
Safety
- during line operation no hazardous liquids or fumes escape into the working area
- the waste air fan is connected to emergency power supply
- during instrument air failure all valves fall in a safe-fail position
- the pickling line is closed by covers made of polypropylene material shaped and stiffened by means of metal structural elements and a set of hydraulic lifting devices enabling access to the tanks interior
- condensate produced by heat exchangers is continuously analysed by conductivity and ph-meters to assure that no acid leaks into the condensate system.
Service
- Engineering services for upgrades of existing equipment
- Turnkey solutions and installations of integrated systems
Environment
- Low to none environmental impact due to the use of the Low Waste Plant
Technical Excellence
- Improved operability and maintenance
- Minimization of the required overall space
