At the end, it is carried out by the tong crane 6 and piled up in the soil. In FIG. 7, 8 is a stopper of the cast piece 2, 3B is a rope (or chain) of the transfer 3, and 5B is a chain (rope) of the transfer 5.

[0004]

However, according to the above-mentioned conventional method for paying out slabs, in the billet / bloom continuous casting machine, the slabs 2 are cast into a single strand or a plurality of strands 1.
When the unloading of steel is stopped due to an accident or the like, the number of slabs 2 collected on the cooling floor 4 by the rope transfer (or chain transfer) 3 becomes smaller than the number of strands. At the end of 4 the number of slabs 2 carried out by the tong crane 6 is reduced, and when the slabs 2 are piled up, as shown in FIG. There is a problem in that the stacking is impossible and the payout work must be interrupted because it becomes dangerous.

The present invention solves the above problems,
It is an object of the present invention to provide a method for paying out a slab, which enables continuous and normal payout even in a non-steady state.

[0006]

In order to solve the above problems, a billet slab dispensing method of the present invention is to collect slabs from a plurality of casting strands and once arrange them on a cooling bed from a predetermined position at the end, and then to the beginning. A predetermined number of slabs are collected together, separated from the cooling bed, carried out by a crane, and then the remaining slabs are moved to the predetermined position repeatedly to dispense the slabs.

[0007]

According to the above method, by collecting and arranging the slabs on the cooling floor from a predetermined position at the end of the cooling bed, the slabs are once arranged on the cooling floor without being affected by the influence even during a non-steady state. By separating the predetermined number of slabs collectively in a predetermined number, the predetermined number of slabs can be always carried out by the crane, and the work of stacking in the soil can be safely continued.
