  • Method of controlling metal strip temperature
    Patent number: 6755923
    Abstract: The recoiling temperature of a metal strip from a continuous heat treatment line is controlled by continuously passing the metal strip through an accumulator system where it passes around spaced accumulator rolls. While travelling through the accumulator, the metal strip is subjected to ambient cooling air and the length of aluminum strip travelling through the accumulator determines the amount of cooling that takes place. The length of the metal strip in the accumulator is in turn controlled by varying spacing between the accumulator rolls around which the metal strip travels. The spacing is preferably controlled by a programmed controller in response to temperature signals.

  • Method for continuous tension leveling of aluminum strip
    Patent number: 6668610
    Abstract: 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°.
