Claims
A method for rolling heat exchange tubes from austenitic steel grades on cold rolling mills, which consists in rolling the tubes in calibers with a groove divergence angle of the calibers within 20-30°, the pipe is fed in the forward position of the cold rolling mill stand with a given rotation angle and in the rear position of the cold rolling mill stand with a given rotation angle, characterized in that the sum of the rotation angle in the forward position of the stand and the rotation angle in the rear position of the stand is 88-92°, while each of the rotation angles should not exceed 75° and is determined by the technical characteristics of the mill.
