The purpose of flattening is to improve the mechanical properties of the steel strip after annealing, eliminate the yield platform of the steel strip, improve the straightness and make the surface of the steel strip reach a certain roughness. Our company designs and adopts a hydraulic flattening machine, which is a four-roll flattening machine. The products it produces have good plate shapes and high precision.
Processing property
The temper mill unit is equipped with hydraulic system and has an elongation control system. The working rolls are positively curved, and the curved rolls are controlled by an electro-hydraulic servo system for constant pressure closed-loop control. The working rolls are equipped with roller cleaners for automatic grinding and wiping of the working rolls. There are anti-wrinkle rollers in front and behind the working rolls. In front of the machine, there is a leveling liquid spraying device, and at the back of the machine, there is a device for removing the leveling liquid spray. The main drive uses a DC motor, and the motor drives a reduction gearbox. The gearbox is a standard one, and the gears are of hard tooth surface. The transmission shaft is of the lower working roll type, and the transmission shaft is a universal joint shaft with a precise positioning system for the transmission shaft head.
