In general, the hot rolling process reheats and extracts the slabs supplied from the continuous casting machine of the steelmaking process at a temperature suitable for rolling in a heating furnace, and performs width rolling and thickness rolling in a bar state in the roughing mill and then in the finishing mill. It is a process of manufacturing a strip of thickness required by the demand. The strip thus produced is wound into a coil-shaped product in the winder after the final thickness rolling is performed.

Referring to FIG. 1, after the strip is wound in a winding machine (Mandrel) 32, the coil 15 manufactured by the strip is transferred by the conveyor 24, and then specimen collection, bending and coil number marking operations are performed. The coil wound by the winder 32 is drawn out in a down state on the coil stripper car, that is, the coil car 35. The coil 15 loaded in the down state on the coil car 35 is rotated 90 degrees by the up-end 36 and conveyed up on the conveyor 24. The coil 16 in this up state is transferred to the bending machine and then banded by the band 28.

On the other hand, when the coil 16 is shipped in the up state on the conveyor 24, the wound state of the coil is loosened by the restoring force of the coil being wound. In particular, when the conveyor 24 is made of a chain type and the coil is transferred to the bending machine by the conveyor 24, the looseness of the coil is more serious due to the vibration of the conveyor 24 in operation. As a result, the coil loosening portion is scratched in a right angle (width) direction.

In addition, when the tip of the thin coil or the loose coil is fitted between the chain and the chain of the conveyor 24, it causes equipment trouble, thereby causing the work of the rolling line to be stopped, thereby reducing the work efficiency.

In addition, when working the coil branched to the post-process in a loose coil state, the tension in the longitudinal direction is generated by the friction between the strips by the tension (Tension) to increase the out of order. In addition, cutting the defective part of the inner and outer diameter scratches of the coil causes a reduction in the error rate.

In particular, the track spray is applied to prevent the coil loosening of high strength thick materials.However, when the track spray is excessively applied, problems such as material deviation occur and HF materials (hot final materials) are finished products after cooling in the cooling plant. Delivery to demand is a source of complaints and claims.

In order to solve this problem, there is known a mobile product packaging machine that can carry out the bending process through the air line connected to the high-temperature coil that is loaded on the conveyor 24 and is being transported. However, such a mobile product packaging machine has a problem that must work in a poor environment and risks such as stenosis by the conveyor (24).

In addition, there is known a mobile band fastening device for a coil that can be moved to a desired coil position to fasten the band easily and firmly to the coil to prevent safety accidents due to manual labor and improve work efficiency. However, such a portable band fastening device for the coil is not suitable for use in the coil in the up state, and there is a problem in that a certain space must be secured at the bottom of the coil in order to use the coil in the down state. In addition, such a mobile band fastening device for the coil can not prevent the scratching occurring during the transfer of the loose coil, such as problems such as lowering the error rate of the coil, poor surface quality and unsatisfactory demand due to material deviations have.
