a lot of customers have a same question: why in the end will be more and more thick aluminum coil use?will appear such problems, because in the process of aluminum production volume, workers omitted an important working procedure, that is straightening.

straightening method aluminum strip mainly straight bend, straighten and flatten three methods.

 (1) flatten straightening to make aluminum coil stock surface light straight, eliminate side bending and wave, with flat to flatten the straightening machine.by to the machine work roll diameter is larger, high surface finish, less pressure when rolling light, make the forward slip of rolled metal is high, so, not only can make the board straight, and can make the surface of the plate bright and beautiful.

 (2) more roll straightening using multiple roll straightening machine process of straightening plates, sheet is through repeated bending effect, make the sheet to produce a bending deformation, reduce the residual stress and residual deformation of plates, in order to eliminate plate wave and warp, get a flat plate.

(3) aluminum alloy sheet stretch straightening tension leveling, also known as tension leveling, divided into single sheet tension leveling and continuous tension leveling two categories.
