Tension levelling lines

The main purpose of tension levelling of metal strip is to correct the strip shape by bending the strip around small diameter rolls under the influence of externally applied tension in order to produce elongation, making the shorter strip fibres longer and equal to the longest fibres and therefore achieving flat strip.

SALICO supplies tension levelling lines for metal strip both to Rolling Mills and Service Centers. Metal strips (carbon steel, stainless steel, aluminium and other non ferrous materials) are processed within a thickness range from 0.08 to 6.5 mm, width up to 2,500 mm and speed up to 600 m/min.

 

SALICO's target is to propose its customers with technical solutions specific to their needs, goals and resources. For this we can choose among a wide variety of Solutions for each line functionality, in order to reach a combination that results in optimum yield of the investment, high quality products, low breakdown rates, ease of maintenance and most of all a safe and ergonomic operation.

 

Main benefits of SALICO tension levelling lines:

  • Safe and ergonomic operation, even for the thickest and hardest materials.

  • High productivity of line through reducing down times by automatic sequences for spools change, mandrel change, side trimmer set up, automatic strip feeding systems, etc.

  • High capacity levellers of robust design, combined with own elongation and drives control algorithms with closed loop operation resulting in optimum strip flatness at exit side.

  • Different arrangements of levellers with single or double levelling stand and single or double decurving stand, depending upon the strip parameters.

  • Dedicated systems for cleaning of the work rolls, decurving rolls and bridle rolls.

  • Highly stable and precise control of elongation.

  • Combination with cleaning and degreasing sections result in optimum flatness and cleanliness as added values.

  • Integration of auxiliary features like our own stitchers or our own embossing systems.

  • Different possibilities of drive of the bridle rolls like all electric or hybrid systems and even pure stretching solutions for certain aluminium alloys.

  • Possibility of combination with Cut to Length or slitting sections on exit side.
