3.6.3 Roller cooling bed

Roller cooling bed is consisted of water cooling roller and drive motor. The roller rotate to the discharging direction, rolling rotate in the axis around its own with the friction force, so that the cooling steel pipe at the same time can reduce the deformation, with a certain hot straightening function, while eliminating the cooling stress. The biggest feature of this kind cooling bed is high cooling efficiency, the curvature of the finished product is small.
