Scale Breakers For Pickling Lines and Aluminum Strip

Tension leveling equipment installed in front of the pickling tanks, where it cracks the oxide layer and corrects shape in one pass.

An intact oxide layer forces the acid to do all the work. Fracturing it mechanically cuts acid consumption and tank time, and the strip comes out flatter as well.

Who Buys Scale Breakers

Who buys a scale breaker.

  • Hot strip pickling line operators
  • Service centres pickling bought in coil
  • Aluminum strip producers removing oxide skin
  • Plants replacing worn scale breaker internals
  • High acid consumption in the tanks
  • Uneven descaling across the strip width
  • Shape defects carried into cold rolling
  • Slow throughput in the acid section

Why Plants Source Scale Breakers From Ascon

What the configuration delivers.

Dual Action In One Pass

Scale fracture and shape correction happen together, so no separate leveler is needed before cold rolling.

Elongation Held At The Right Level

Pickling efficiency is maximised at up to 7 percent elongation on a tension leveler type scale breaker, and the machine is set to hold that band.

Roll Units And Cassettes As Spares

The bending and correcting roll units, cassettes and rolls are all produced here for later replacement.

Application Scenarios

Line positions.

Push Pull Pickling Lines

Medium width lines processing single coils without welding, at speeds up to 180 m/min.

Continuous Pickling Lines

Wide hot strip lines up to 1850 mm ahead of the acid tanks.

Aluminum Finishing Lines

Removing dense oxide skin and stretch bend levelling wide aluminum strip.

FAQ

Scale Breakers Buying Questions

How much acid does a scale breaker save?

Cracking the oxide layer lets acid penetrate instead of dissolving an intact scale, which saves a significant amount of acid. The exact figure depends on your scale condition and tank practice.

What elongation should we run?

Up to 7 percent. Research confirms pickling efficiency is maximised when elongation does not exceed 7 percent on a tension leveler type scale breaker.

What flatness comes out?

On our push pull configuration, below 5 IU with edge waves, centre waves, buckles, warping and camber removed.

Can the machine be retrofitted?

Yes. Send the line layout, the space available before the acid tanks and the drive data.

Does it work on aluminum?

Yes. The 1850 scale breaker removes dense oxide skin from aluminum strip and stretch bend levels it at the same time.

What spare parts will we need?

Bending and correcting roll units, roll cassettes and the rolls inside them. We hold your drawings so repeat sets are identical.
