Method for continuous tension leveling of aluminum strip

摘要

An aluminum alloy sheet of the AA 6000 series is subjected to a continuous tension leveling procedure. The sheet is passed through a set of pull rollers and a set of brake rollers and subjected to a longitudinal tension between the two roller sets. Also while travelling under longitudinal tension between the two sets of rollers, the sheet is subjected to bending and reverse bending over a series of small rollers at a wrap angle in the range of about 0 to 12°.
