1. It uses the technique of individual-roller driven patent, eliminates the mechanical intervention of each roller, negative-torque phenomenon and each kind of problem caused by it, therefore it prolongs the life of working rollers and protects the surface of the workpiece
2. Individual-roller driven also achieves the mode of linear decreasing leveling, and conforms to the leveling rule of steel plate, reaches the leveling precision as required. Since the pressing value decreases gradually, this mode decreases the total distortion degree of the material relative to the mode of deforming leveling. Therefore the total leveling forces and power-waste will be reduced so as to save the energy source
3. It uses holistic close frame, transitted by foursquare circular, and arranges the steel bar reasonably, so it has both a good rigidity and intensity, exhibiting a beautiful appearance and a smooth line
4. All the rolling bearing, worm gear case and active pair such as lead crew pair use the bilinear electric oil filler to lubricate concentratively, and it include one alarming safety device
5. The working-rollers choose the special high-quality steels which were used on the cold mill and leveling machine only, and were quenched on surface. Top-roller, bottom roller together with leading-roller all choose the rolling bearing which were used on the new-style rolling mill, and have a capacity of resisting collision and vibration, therefore the intensity and rigidity of the working-roller and the life of bearing are assured sufficiently
6. The controlling system has an advanced technique, compact structure, and it operates conveniently. With a strong controlling function, it runs reliably and is easy to maintain
