Description of the Related Art Conventionally, when a billet is hot-rolled, for example, the billet is heated to a predetermined temperature in a heating furnace, and then once sent to a heat-retaining furnace to retain heat, and then sent to a rolling process. In that case, so-called skid marks occur because the billet contacts the water-cooled skid in the heating furnace. The uneven heat of the billet due to this skid mark has the adverse effect of causing variations in product dimensions due to rolling,
Further, depending on the rolled material, it may be required that the temperature deviation be minimal from the beginning. In order to minimize the unbalanced heat due to such skid marks, for example, JP-A-52
In Japanese Patent Laid-Open No. -43712, as shown in FIG. 5, a technology is described in which a billet extracted from a heating furnace is turned by a turning device B before being introduced into a heat retention furnace.

By doing so, one turning motor 15 is shared. The rotary motion of the turning motor 15 is converted into reciprocating motion of the turning motion transmitting rod 22 by the link mechanism 19 and the link mechanism 18 via the turning shaft 23. Since the turning claw 21 is rotatably pin-connected to the ram 4 by the turning center pin 17, the reciprocating motion of the turning motion transmitting rod 22 (the left and right arrow movements in the figure) causes the turning claw 21 to rotate. Is configured to rotate 90 ° around the rotation center pin 17.

In the walking beam type heating furnace 1, the steel slab 3 on the skid 2 in the heating furnace which has been heated to a high temperature and carried to the vicinity of the extraction port 12 is moved by the transfer device A in a rectangular motion so that the steel table outside the heating furnace 1 is transported. 10
Transferred to the top. At this time, first, the ram forward / backward movement motor 5
Is driven to rotate the pinion gear 7 attached to the forward-reverse drive shaft 6 and engages with the rack 8 so that the plurality of rams 4 simultaneously move to the extraction port 12 of the heating furnace 1.
It moves back and forth toward the steel slab 3 in the vicinity. (FIG. 1) At this time, the turning mechanism 20 built in the transfer device A also moves together with the ram 4.

ような状態で待機設定して置く。FIG. 4 is a step diagram showing the operation of the transfer device A and the operation of the turning mechanism 20 at that time. Turning claw 21
As described above, the rotary motion of the turning motor 15 is converted into the reciprocating motion of the turning motion transmitting rod 22 by the link mechanism 19 and the link mechanism 18 via the turning shaft 23,
This causes the turning claw 21 to rotate about the turning center pin 17. When the ram 4 moves forward, the turning claw 21 is set in a standby state with the claw mouth opening upward as shown in FIG. 4 (a).

を少なくすることができる。Next, when the ram 4 passes between the skids 2 in the heating furnace 1 and reaches below the steel slab 3, the advance of the ram 4 is stopped. Then, as shown by the broken line in FIG. 1, the ram 4 and the turning claw 21 engaged with the ram 4 are raised by the ram lifting device 9 (FIG. 1), and the steel piece 3 on the skid 2 is turned by the turning claw 21. However, by setting the angle of the turning claw 21 so that the mouth of the claw 21 opens upward as shown in FIG. Even if there is, the position can be corrected so that when the turning claw 21 lifts the steel piece 3, the steel piece corner portion 13 of the steel piece 3 just slides into the inner angle of the turning claw 21.
Thereby, when the transfer operation of the billet 3 is completed, the billet 3
It is possible to reduce the error in the position of the steel slab when the slab is placed on the transport table 10.

(FIG. 1) At the time of the backward movement during this rectangular movement, the turning claw 21 is turned so that the ram 4 moves to the transport table 1.
When the vehicle retreats to 0, the state shown in FIG.
Make the state of (c). Therefore, while the ram 4 is retracted, the turning motor 15 is driven to pull back the turning motion transmitting rod 22 to the side opposite to the heating furnace side, and the turning pawl 21 is moved.
The rotation center pin 17 is rotated about the rotation center. Then, at the end of the backward movement of the ram 4, the billet 3 is in a state of being rotated by 90 ° around the longitudinal axis of the billet 3.

ある。Next, the ram lifting device 9 is used, as shown in FIG.
As shown in FIG. 3, by lowering the ram 4 at the position of the transport table 10, the steel piece 3 in the state of being rotated by 90 ° is transferred from the turning claw 21 onto the transport table 10, and the transfer operation and the turn operation are completed. (Fig. 1). After that, FIG. 4 (e)
As shown in FIG. 3, the ram 4 stands by, and the turning claw 21 moves the turning motion transmitting rod 22 forward so that the angle of the turning claw 21 is changed to a state in which the mouth of the claw opens upward. Restore and wait until the next operation. When the transfer of the billet is not required when using this transfer device, the transfer operation is not performed by 90 ° by not performing the roll operation during the transfer operation described above. Of course, it is possible to do it.

Since the rolling movement of the billet can also be performed during the transfer movement of the billet, the time required for rolling the billet can be included in the time required for the loading, and as a result, the heating including the rolling movement can be performed. The time from the extraction of the furnace to the next step is greatly shortened compared to the conventional case, and the waste of energy due to the heat dissipation of the heated steel billet can be reduced. Further, it is of course possible to perform only the transfer operation regardless of the necessity of turning the steel bill.

Not only the extraction of the steel billet from the inside, but of course, the invention can be applied to the transfer of the steel billet from the transport table to another transport table after the steel billet is extracted from the heating furnace. That is, it can be used at any place in the billet conveying path from the extraction of the heating furnace to the next step when the transfer and turning of the billet of heating are required. Also,
The means for moving the ram forward and backward is not limited to the pinion gear and the rack. Also, the ram lifting device may have a crank structure, an eccentric ring structure, or the like.

等の極めて優れた効果を奏するものである。As described above, in the transfer device of the present invention, since the transfer device has a built-in rolling mechanism, the rolling motion of the billet about the longitudinal axis is during the transfer motion. Since it can be carried out in the heating furnace, it is possible to significantly reduce the time required for turning in the time from the extraction of the heating furnace to the next step, and as a result, it is possible to reduce the energy loss due to heat dissipation from the heating steel billet. The effect of being able to be obtained is obtained. In addition, since it is not necessary to separately provide a transfer device and a turning device as in the conventional case, the device itself becomes compact and the installation space of the device can be reduced. Furthermore, by setting the angle of the turning claw that accompanies the transfer device so that the mouth of the claw opens upward, the turning claw of the turning claw just when the steel piece is lifted by the turning claw is lifted. By correcting the position such that the corner of the steel piece slips into the inner corner, it is possible to reduce the error in the position of the steel piece at the end of the transfer operation, which is an extremely excellent effect.
