FIELD: continuous rolling of strip, namely rolling strip having different thickness portions joined through transition wedge-shaped portion. ^ SUBSTANCE: method is used for rolling metallic strip 1 in rolling mill having at least two rolling stands. Metallic strip 1 has at least two zones 3,4 of different thickness mutually joined through wedge-shaped or approximately wedge-shaped transition portion 2. Rolling rate in rolling stand at rolling wedge-shaped portion 2 is tuned depending upon forward slip of rolling stand and also depending upon temperature of metallic strip 1. Apparatus for rolling includes rolling mill having at least two rolling stands providing tuning of rolling rate at rolling wedge -like or approximately wedge-like transition portion 2 of strip depending upon forward slip of rolling stand and upon temperature of metallic strip 1. ^ EFFECT: enhanced quality of rolled products. ^ 2 cl, 5 dwg |
