げ寸法にまで圧延することが公知であシ通常であった。Conventional technology (1) The above-mentioned line for rolling beam sections usually consists of a double reversible nutand, a so-called brief-down stand, and a general-purpose stand connected to this.The general-purpose stand has a swaging stand in front or between is set up. In order to be able to roll a constant program of different beam dimensions, each beam shape is fitted with a separate leader bath on the stands of the rough rolling line.
It has been known and common to roll to finished dimensions with successive stands of successive finishing fins.

る。The rolling of the leader bus, which is called the last bus of the reversibly designed roughing line, is carried out in three to five cross-sectional holes in the stand of the roughing line, depending on the size of the profile. If it was necessary to provide a corresponding hole shape for each finishing dimension, the same number of different sets of rollers would have to be used for the roughing line brief-down stands, depending on the number of different leader buses. is self-evident.

＃斜を備えている。The integration of leader buses of various finishing dimensions into the leader pass gauge of the breakdown unit requires a corresponding adaptation of the universal roller modification of the finishing line. 5 Corresponding modifications are shown in the drawings by way of example for dimensions IPE 160 to 220 of the prick-down stand. This (+i
As is clear from the diagram, the leader bus dimensions of the rolled beam area undergo different rolling for the first time in the finishing line, where the essential feature is that the beam IPE 16
0 undergoes strong swaging of the flange at the first swaging stand E1 and only a slight widening of the vertical sides, while the flange is hardly swaged at the swaging stand El of beam IP2201 The vertical sides are significantly widened. This continues with the general-purpose gauges, and moreover, the general-purpose gauges U6 to U1 are 05 degrees empty U with the U6 stand.
Equipped with a horizontal roller flange that can be punched up to 25 degrees on the l stand.

る。A special feature of the invention is that a strong swaging of the flange is carried out for rolling of comparatively small finishing dimensions in the swaging stand (6) and also for rolling of comparatively large dimensions. A strong widening of the vertical sides is carried out within each continuous finishing line for rolling of vertical dimensions.

びＶ直室への対応する調整をも可能にする。In order to achieve a strong widening of the vertical sides, it is proposed by another feature of the invention that the flange slope of the horizontal lobe from the finishing stand to the first general purpose stand is approximately 0.5 from stand to stand. The temperature rises in the range from 25 degrees to 25 degrees. Such a strong flange inclination in the stands of the finishing line not only allows a strong widening of the vertical sides of large profile dimensions, but also an advantageous reworking of the horizontal rollers by turning and a corresponding adjustment to the V-shaped chamber. do.

。Effects of the Invention If the invention makes it possible to perform only one leader bus in at least two finishing dimensions with a prick-down stand, at the same time save investment costs! Succeed in at least cutting it in half. At the same time, the advantage arises that only half as many rollers need to be stored for the rough rolling line, so that much lower storage costs arise. Finally, according to the proposal of the present invention, 2
A further saving device results from the fact that the refurbishment time of the reversible stands of the roughing rolling line is reduced by at least half, since the four sections from the book are rolled by only one leader bath.
