Components with the same names as those in FIG. 3 are given the same reference numerals and their explanations will be omitted. FIG. 1 shows one embodiment, and in the same figure, 9 is a secondary cooling bed, which is provided between the conveyor 10 downstream of the cold shear 4 and the conveyor 11 upstream of the inspection/counting device 5. This allows the feeding speed by the drive device 12 to be controlled in order to cool the bar 8 to a predetermined temperature. That is, by controlling the drive device 12, the cooling rate of the bar 8 in the secondary cooling bed 9 can be set arbitrarily. Secondary cooling bed 9
On the inlet side of the bar, a pitch jamming device 13 is installed to narrow the spacing between the bars 8 in order to increase the cooling efficiency by increasing the residence time in the secondary cooling bed 9. Further, on the exit side of the secondary cooling bed 9, a forced cooling device 14 using water, air, mist, etc. is installed in order to increase the cooling rate.

時でも、常に通常材と同じ温度にできる。 According to the above configuration, in the case of special steel, bar steel 8
is cooled in the primary cooling bed 3 to a temperature of 300 to 600°C, which is higher than the cutting temperature range of ordinary materials (about 200 to 300°C). The long steel bar 8 that has been warm cut by the cold shear 4 is taken from the conveyor 10 to the secondary cooling bed 9 via the pinching device 13, and is conveyed while being secondarily cooled by this cooling bed 9. . Then, on the exit side of the cooling bed 9, the bar 8 is forcedly cooled by the forced cooling device 14,
After reaching the desired predetermined temperature, the conveyor 11
sent to. Therefore, the temperature of the product entering the inspection/counting device 5 can always be the same as that of normal material even when it is warmly cut by the cold shear 4.

め、作業者の環境が改善される利点がある。(Effect of the invention) According to the present invention, a long steel bar cut at a warm temperature of 300 to 600°C, which is higher than the cutting temperature range of ordinary materials, is cooled to the same level as ordinary materials in a secondary cooling bed and refined. Since the product is sent to the finishing equipment, the temperature of the product carried into the finishing equipment is the same as that of regular material, allowing for stable work. In addition, since long steel bars cut at warm temperatures can be handled at low temperatures, there is less bending of the product.
Off-line correction work is reduced. Moreover, the refining equipment can be used for cold processing, and there is no need for high heat countermeasures such as sensors and tags. Furthermore, since it is handled at a low temperature, there is an advantage that the environment for workers is improved.
