率の良い搬出搬入作業を可能とする。This stopper 40 is designed so that when the rolling process is stopped for some reason, a locking body 42 is lowered onto the conveying path 1 to stop the hot steel billet 2, and at the same time as this stopper 40 is activated, the carrying-in device 20 is activated. Interlockingly, the hot steel slab 2 is carried into the heat retention furnace body 4. Note that the locking body 42 is normally lifted upward by a pneumatic or hydraulic cylinder 41. The present invention configured as described above has a structure in which an input slot 5 for hot sardine pieces 2 is arranged so as to be openable and closable adjacent to the conveyance path 1 for conveying hot steel pieces 2 discharged from a continuous casting machine to a soaking furnace 12. Since a heat-retaining furnace body 4 is provided, and a heat insulating material 9 is provided on the inner peripheral surface of the heat-retaining furnace body 4, conventionally, it is possible to prevent problems in the rolling process or in the case of periodic temporary suspension. The amount of heat held by the hot hammer piece 2 can be maintained by isolating the hot groove bacteria pieces 2 which are left to cool as they are from the outside air. Moreover, the heat retention can be further sustained by the heat insulating material 9. Therefore, there is no need to reheat the key piece and send it to the soaking furnace 12 as in the past, so there is no need to provide a heating furnace for the cold key piece, and the equipment can be simplified.
This allows the heating raw material unit in the soaking furnace 12 to be kept low. In addition, since the skit rail 7 is arranged at the bottom of the heat retention furnace body 4 at right angles to the conveyance path 1, it is possible to push and extrude the hot steel billet 2 from the width direction, and the movement required to take in and out the hot steel billet 2 is possible. This enables efficient loading and unloading work while minimizing the amount of equipment and simplifying the equipment configuration.

低減が図れるものである。Moreover, since the heated steel pieces 2 are fed and stored with their sides in close contact with each other, the area of contact with the outside air can be reduced and heat retention can be carried out efficiently. Since the heat retention furnace body 4 is connected to the scarlet gas duct 13 that introduces the high-temperature exhaust gas from the soaking furnace 12, the high-temperature exhaust gas from the soaking furnace (1200 CO to 12
5°C) can be used effectively, and the unit of heating raw material can be further reduced.
