Scale Breaker

Scale-breaking tension leveller, also called scale breaker, is generally used
for continuous pickling units. Scale breaker machine applies to bend stress to
strip steel. The front and rear bridle roll applys tensile stress to the strip;
Under the coordination of these two stresses, the strip can produce moderate
elongation under the condition that the tensile stress is far below the yield
limit of the material. On the one hand, this extension realized by scale
breaker can improve the shape of the strip and eliminate the defects such as
wave, buckling and camber, at the same time, the internal stress and yield
platform are eliminated to improve the mechanical properties of the strip. On
the other hand, due to the huge difference between the oxide layer on the
surface of strip steel and the iron matrix in performance, under the action of
bending and stretching, a large number of oxide layer will fall off, and the
oxide layer still attached to the surface will also crack, so as to improve the
efficiency of acid tank pickling descaling.

Scale Breaker Structure Advantages


Structure Advantage of Scale Breaker Tension Leveler (Dry Type)


Two sets of bending unit and one set of leveling unit of the flat rolling
machine can effectively remove the oxide skin on the surface of the strip and
improve the shape of the strip. Two sets of bending units can also be used for
one use and another one as spare according to the conditions of incoming
materials and process requirements.

Dry type scale breaker is equipped with blowing system, sealing system and dust
collection and dust removal air net, to ensure the environment of equipment
usage, at the same time to effectively collect the broken oxide scale.

The frame of scale breaker is an assembly part, each part is annealed
separately to eliminate participating stress and ensure the frame is not
deformed after long-term use. At the same time, it also provides convenience
for later maintenance.

The roller changing device is safe and convenient. The dry type scale breaker
is driven by hydraulic pressure. One or all of the roller boxes can be replaced
at one time.

The top roller system of dry type scale breaker can be opened quickly to
prevent the rolls being damaged when weld seam passing. The lower roller system
is used for improving the version by adjusting the insertion amount of the
lift. The ball cage coupling is used to connect the driving motor, the lift and
the detection encoder to facilitate the flexible adjustment and maintenance.

Structure Advantage of Scale Breaker (Wet Type)

There are two sets of bending units and one set of leveling unit of scale
breaker, which can remove the oxide skin on the surface of the strip
effectively and improve the shape of the strip. Two sets of bending units of
scale breaker can also be used for one use and another one as spare according
to the conditions of incoming materials and process requirements.

The frame is an assembled part, and each part is annealed separately to
eliminate participating stresses and ensure that the frame is not deformed for
long-term use, which also provides convenience for later maintenance.

The roller changing device of the wet type scale breaker is safe and
convenient. It adopts hydraulic drive and can replace one cassette or all
cassettes at a time.

The top roll system can be opened quickly to prevent roll damaged when welding
seam passing, and the top roll system is adjusted by the cylinder to improve
the flatness.

The top roller system and the inner wall of the frame have taken effective
medium anti-rust measures, which can effectively prevent rust water from
dripping on the surface of the strip and affecting the quality of the strip.

Wet type scale breaker is equipped with spray device to clean the oxide scale
on the surface of the strip and roll and to ensure the descaling effect.

The main machine of scale breaker has taken effective waterproof, anti-rust
measures, good sprinkler and backwater system, which can ensure long-term
reliable and stable operation of equipment.
