Working Principle Of W43C roller levellers

1

The upper and lower rollers of the main drive system are fully driven, driven by two motors, can be braked in an emergency, have a soft start device, have a small impact on the power grid, have reliable performance, low noise, and compact structure.

The upper and lower supporting rollers are supported by multiple rows of diameters and are arranged in a chess pattern with the work roller. The bottom is equipped with an integral inclined iron adjustment mechanism. The shape of the upper and lower leveling rollers can be adjusted by manual fine-tuning to maintain the rigidity of the work roller and level the wave of the thin plate. When bending, convex, and concave buckling deformation, it is necessary to use the backing roll to change the convexity of the work roll, and manually adjust the opening amount and inclination angle of the upper leveling roll, which can easily adapt to the correction requirements of wave bending and scoop-shaped plates.

Adopt the form of small roll distance and small roll diameter to improve the leveling quality. Due to the small diameter of the work rolls, the work rolls have small diameters and greater correction force, so the backup rolls are densely arranged in a chess-like distribution, which not only increases the horizontal rigidity of the work rolls but also has a better bending effect.

The position of the correction roller is individually adjustable: This structure can flexibly adjust the reduction according to the requirements of the correction process, so that the reduction of each correction roller is in the best state, and the plate can be corrected with less bending times.

Process control system: The computer model can set the roll gap according to the thickness, width, flatness and temperature of the corrected steel plate, automatically bite the plate and feed, and has the functions of overload protection and AGC bounce compensation.
