1. be used for method at the rolling band (B) of the inside of the milling train that is used for metallic article, described milling train has at least two supports, described band (B) is clamped in the described support simultaneously, adjusts the lateral position of described band (B) according to described method, and described adjustment comprises following operation:

  • -in the downstream of each support of described milling train, determine the value of the described band of representative (B) simultaneously along the lateral position of the line of the moving direction that is transverse to described band, and calculating algebraically difference (Δ

    xp) between described lateral position and reference position (6), described band (B) is clamped in the support of described milling train;

    -treat on each support of described milling train the additional tilt value (Sp) that---described band (B) is clamped in the described support---applies from described difference (Δ

    xp) calculating, thereby make described algebraically difference (Δ

    xp) be lower than predetermined threshold, carry out the calculating of described additional tilt value (Sp) by described difference (Δ

    xp) and gain matrix (K) are multiplied each other, described gain matrix is by determining carrying out modeling in conjunction with the relation of the described inclination (Sp) of the backing roll of the described difference (Δ

    xp) of described band and described milling train;

    -corresponding additional tilt is set (Sp) send each described mill stand to;

    And-repeat described operation at interval with preset time, no longer be clamped in last support of described milling train until described band (B).
