Benefits about Scale breaker

Tension leveler is widely used in strip rolling line, such as galvanized wire, acid rolling line and color coating lines. When used in the acid line rolling machine, we called scale breaker, which is located in front of pickling tank, hot-rolled strip in a continuous alternating stretching and bending under the combined effect of plastic deformation, while the hot-rolled strip does not have the oxide surface plastic deformation. In the process of tensile Strip of plastic deformation, the surface of oxide fractures, thus saving a lot of acid. Hot-rolled strip at the same time also get a better correction. The core component of tension leveler is the bending and correct roll units.

Scale breaker is used to eliminate all kinds of three-dimensional plate shape defects such as bilateral wave, unilateral wave, middle wave, two-rib wave, warping, buckling and potential bad plate shape.

In the process of calendaring strip, the above-mentioned plate shape defects will be occurred in the coiled strip due to bad roll shape and roll gap shape. These defects are caused by the uneven longitudinal extension of the rolled piece in width direction and the disorder of rolling stress. In order to eliminate the bad shape of the coiled strip and make the internal stress tend to be uniform, the coiled strip needs to be corrected.

The structure of Scale breaker is two bending and two leveling single drive type,the scale breaker roll units we designed includes two sets of φ60mm bottom extension units, two sets φ60mm top extension units, one set φ100mm bottom leveler roll units and three sets φ250mm deflector roll.

Application of Scale breaker

• Scale breaker are extensively used in the field of Iron and steel manufacturing.
  Steel manufacturing is one of the main application areas of tension leveling machines, which are usually used in casting, rolling, drawing, straightening and other links. In the construction of high-speed railway, the tension leveler is also very important.
• Scale breaker are popular use for Rail transit.
  In addition to high-speed railways, subways, trams, airport integrated transportation hubs and other transportation construction all need to use tension straighteners for the processing of metal sheets.
• Scale breaker are widely utilized in Automobile manufacturing field.
  Automobile manufacturing is also one of the main application areas of tension leveling machines.Tension levelers can be used to process car bodies, doors, roofs and other components.
• Scale breaker are used in the entertainment industry home appliance manufacturing likeTelevisions, refrigerators, air conditioners and other household appliances also need tension leveling machines for plate processing in the manufacturing and production process.
