Abstract

PURPOSE:To prevent generation of various troubles depending on short pieces of material for stabilizing the operation, by operationally forecasting the residual length of rear end of the rolled material, produced at the cutting work into segments, using the operator, and by actuating various devices depending on the result of the operation. CONSTITUTION:The material is rolled by the finishing mill group 1 and is cut into segments of length (l), plural times of length of the ordered product, by the segment cutter 3. The cut rolled material 12 passes through the cooling-bed-carry-into device 4, and is laid on the cooling bed 7 where the material 12 is cooled and is sent to the discharge device 10. Specified number of rolled materials 12 are cut into a length of the ordered product by the cold cutter 11. Besides, the size, etc., of the rolled raw material are inputted into the operator 20 which then operates the product length and the number of times of cutting. The rolled material's rear end position detecting command is delivered from the counter 23, and the switch 24 is closed, and the hot steel detector 2 is actuated. Hereby, the rear end position of the rolled material is detected, and the result of the detection is sent to the operator 25.
