PURPOSE:To eliminate occurrence of bending due to difference in length and improve yield of products by dividing short material and long material to separate cooling beds. CONSTITUTION:When short material passes under a rolled stock detector 9, a switching device 8 is switched to a carrying route 7B side, and the front half part is carried into a cooling bed 4A. When the rear half part passes successively under the rolled stock detector 9, the switching device 8 is switched to a carrying route 7A side, and the rear half part is carried into a cooling bed 4B. Accordingly, the front half parts are totally carried into the cooling bed 4A and the rear half parts are carried into the cooling bed 4B. By the above, short material and long material are divided to separate cooling beds. Consequently, cutting length can be controlled by small number of persons, the quantity of rear end block can be reduced and yield of products can be increased. |
