Abstract (en)

[origin: JPH01313101A] PURPOSE: To roll a rolling stock into a cross-sectional shape of a correct dimension by locally and preliminarily determining by means of a pre-stand, the dimension of a peripheral range of the cross section of the rolling stock which runs into a pair of rolls of next main stand after leaving the last pre-stand. CONSTITUTION: A rolling stand, wherein a vertical roll pair 1 forming an opened pre-roll coverlet and a horizontal roll pair 2 forming a closed roll coverlet are arranged, is provided in the back side of the vertical roll 3 of the last stand 4 in a continuous forming stock rolling line. And the peripheral range of the cross section of the rolling stock is locally rolled by the vertical roll pair 1 so that the rolling stock running into the rolling stand is not remarkably deformed.
