This is because, in order to solve the problem of the cooling uniformity of the lap joint point and the non-lap joint point of the coil, the stelmor air cooling line generally uses a heating device to make the air volume at the lap joint point position larger and the air volume at the non-lap joint point position smaller, and if the wire rod coil deviates during transportation on a roller way, the lap joint point positions at both sides of the coil will deviate from the position with the largest air volume, resulting in insufficient cooling. Meanwhile, the friction between the wire rod coil and the side wall of the roller way can cause the surface of the wire rod to be scratched, and the service performance of the wire rod is deteriorated.
