Description

Apparatus for conveying rolling coil

The present invention relates to a coil transfer apparatus, and more particularly, to a coil transfer apparatus for carrying a coil wound in a hot rolling process.

The slabs are rolled to produce strips, and the strips are wound by a mandrel device to facilitate storage and transport. A separate coil carrier and a coil transfer device are needed to carry the wound strip.

The coil carrying part draws the wound coil from the mandrel device and carries the coil, which requires a structure for stably mounting the coil. Further, the coil conveying unit and the coil conveying apparatus require a conveying structure capable of conveying the coil wound to a predetermined position.

Here, the coil carrier is generally referred to as a " coil car ", and a support roll is provided to seat the coil.

At this time, if the supporting force against the coil is weakened, there is a problem that the internal winding of the coil is distorted by the self weight of the coil. Further, after the coil is wound, there is a problem that the transformer generates heat and the coil is distorted.
