Multirolls Levellers

The purpose of the leveller is to produce flat strip eliminating all the out of flatness defects which may be present in the incoming strip like center buckles, side buckles, long edges, cross bow or coil set, but flat strip does not mean just apparently flat but also true flat or flat “without memory”, meaning that the sheets will remain flat even after further downstream processing, and will not return back to their original condition, due to the counter action of trapped internal stresses.


The new generation of SALICO multiroller levellers has been specifically conceived to deliver a high plastification ratio over the strip section. By turning into plastic most of the internal fibers of the strip section (>80%), the internal stresses are dramatically reduced down to an absolute minimum level, making sure that the flattness of the sheets will remain after further processes like stamping and mainly laser cutting


An intelligent combination of work roll diameter, rolls pitch, number of work rolls, upper frame screw down capacity and drive motor power and transmission, has made it possible to obtain perfectly flat cut sheets without memory at the exit side of our levellers, even for the highest strength materials, up to 1.500 Mpa.


SALICO Levellers of different sizes have been constructed over the years with work rolls ranging from 25 mm in diameter for the thinner aluminium strips up to 180 mm for the 25 mm thick strip
