This straightening machine is different from the YJZ60B hydraulic straightening machine. It adopts the structure of the YJZ800 mechanical straightening machine. Two upper straightening wheels straighten the flange plate from up to downwards. Unlike the mechanical straightening machine, the power to push the straightening wheels is the hydraulic cylinder rather than a reducer. The use of upward pressure straightening has the following characteristics:

1.Both sides of the flange plate can be rectified separately, and the effect of the correction can be controlled to make the corrected web vertical;

2. The roller table does not need to be lifted, the cost is reduced, and the operation is simple.
