This design uses a large number of guide tubes and repeaters in a parallel batch finishing mill, and when rolling small A-beams or C-beams, the rolled material rolled from one base mill is adjacent. The present invention relates to a section steel automatic rolling device which is configured to automatically continuously feed into a next rolling mill.

In the conventional parallel batch rolling mill, the rolling material is transferred to the next rolling mill adjacent to the rolling mill by an attractive force or by using an auxiliary device such as a transverse device or a Y-shaped roller table. In the case of transferring general round steel (not a-beam or c-beam) from the rolling mill to the next rolling mill, the repeater is driven by the thrust force of the head of the rolled material discharged from the rolling mill simply by installing a △ repeater. Induced along the Groove of the rolling mill, the impact moment is applied in the opposite direction at the moment when the head of the rolled material is inserted into the next rolling mill. (Impact loop) is generated as a result of which the dark lead material is separated from the groove (Groove) to form a new loop to make a continuous rolling, In general, the cross-sectional shape of the round steel rolling material is round, square or elliptical (Oval), so that the shape is similar in cross-section coefficient in any direction, so that it bends with the same force in any direction, so that it is easy to detach from the repeater trough when an impact loop occurs However, there was no problem, but in the case of a-beam or c-beam, there is a characteristic of bending only in a certain direction, so when using a conventional repeater, it is impossible to separate the rolled material out of the repeater gutter until now. Since the rolled material is completely passed through and then it is transferred to the next rolling mill, it takes much time to transport it and the strength of the rolled material increases according to the temperature drop of the rolled material due to the passage of time. Failure during the rolling process such as shortening Yeotdeon and there were drawbacks.

In order to correct such a defect in the related art, the rolling material is twisted in a direction that is easy to bend between the rolling mill and the rolling mill while passing through a plurality of guide tubes, leading to the repeater, and inclining one part of the repeater's trough to the impact route. It is an object to make it possible to continuously roll like a round steel (특수) in a special shape to facilitate the separation by.

The invention will be described in detail with reference to the accompanying drawings.

This design is known between the rollers (3) (4) (5) and the furnace (6) in a known rolling device formed of a drive motor (1), a reducer (2) and a roller (3) (4) (5). A plurality of fallopian tube guide tubes 7 are detachably attached to each other, and a gentle inclined portion 10 is formed on one side of the inlet port outer wall inlet of the known repeater 8.

Reference numeral 11 denotes a section steel (rolled material) that twists as it passes through the induction pipe 7, 12 is an impact loop of the rolled material generated by the insertion reaction force, 13 is an outlet pipe, and 14 is an inlet pipe.

In this design, the inlet portion of each induction pipe 7 is in the form of a trumpet as shown in FIG. 4, so that the rolled material can be transferred without progress without difficulty and the rolled material is installed to be twisted gradually. It can be easily bent along the trough 9 by 90 ° twisting from the roller 3 to the outflow pipe 13 and is formed at the moment when the head of the rolled material enters the inflow pipe 14. The impact loop 12 starts to be separated from the inclined portion 10, and the rolled material forms a new path that flows from the outlet pipe 13 to the inlet pipe 14 through the furnace 6. The reason for guiding the rolled material to the flat furnace 6 is to construct a new path that flows into the inlet pipe 14 through the flat furnace 6. The reason is that the speed difference between the roller 3 and the roller 4 is different. Between the outlet pipe 13 and the inlet pipe 14 If this is causing a change there, because the trough (9) Back to the progress of the crowd within.

This design allows the rolled material to be twisted into a position that is likely to be bent by a plurality of guide tubes 7 while passing through the three rollers 3, 4 and 5, and the inclined portion on the outer wall of the trough 9 10) is formed is a useful design with the advantage of easy separation of the rolled material of a special type, such as a-beam or c-beam.

Claims (1)

As shown in the drawing, rollers (3) (4) (5) and rollers in known rolling mills formed of drive motor (1), reducer (2) and rollers (3) (4) (5). The parallel arrangement type which uses the repeater which attached | attached many fallopian tube-shaped induction pipes 7 between them, and formed the inclination part 10 in one side of the outer-wall inlet of the well-known repeater 8 in between.
