The innovative tension levelling system was planned by us mainly for the stainless steel processing; afterwards it was applied also to aluminum strips, cold-rolled steel, pickled steel, galvanized steel and pre painted steel.
The tension levelling system process helps the strips leveling keeping its tension during the working phase before and after the leveling machine.
Thanks to its sophisticated software and several possible settings, many strips judged not good to be leveled have been processed successfully. The installed power guarantees the right elastic plastic properties of the material.
The tension levelling system allows the achievement of a high leveling quality, stabilized stress relieved material adapting sheets to several workings, to laser cutting, to punching machines, to automatic machines, etc. Moreover the tension levelling system enables to get excellent results with the requalification of strips with above average rolling defects.
Compared to a conventional system, with the tension levelling system some economic benefits are evident:
-the range of processed thicknesses increases (for example 0.4 to 4 mm) using one single leveler.
-only one leveler instead of two or one leveler with double cassette;
-less power (less vertical load on the leveler with consequent energy saving during the plant running);
-reduced maintenance costs (one single leveler having rolls with a larger diameter and less
-applied vertical load requires less frequent maintenance);
-reduced costs for spare parts;
-rise in productivity due to the less frequent stops of the machines necessary to choose and
-replace the leveling cassette proper for the programmed working of the strips;
-upgrade of the second-best strips;
-the strip keeps its tension up to 1,3 m from the leveller, practically the strip tail and the strip centre are leveled in the same way;
-ease of utilization of this system.
