Abstract
The invention relates to a method for rolling a metal profile into a metal strip in which method the technique of a profiled rolling in combination with a strip rolling is used, comprising that during the at least two-staged profiled rolling the metal rod is divided into two symmetrical segments. These segments are spread into the lateral regions of the material to be rolled into a flattened profile which is as an object for at least one-staged strip rolling so that the spread ratios between the diameter of the rod and the width of the strip of greater than 2,8:1 are achieved.
