Slab Continuous Straightening Unit of Continuous Casting System
New Anjie adopts the continuous straightening unit mainly functioning in billet withdrawal and the continuous straightening of the circular arc billet.
The drive system of the straightening unit uses variable frequency motor, making the motor capable of changing speed within a larger range to adapt to the needs of different withdraw speeds. During the operating, the straightening unit has to overcome the friction between the strand and the mold wall, resistance of secondary cooling system, straightening resistance, etc. Since there are many factors that influences the withdraw speed, so the speed must be adjusted based on different conditions. Increase the transmission speed when driving the dummy bar. The lifting and pushing of upper driving roll and stripping roll and are controlled by metallurgical hydraulic cylinder, featuring motion balance. The cylinder has a working pressure of 4-8Mpa. This rolling body of straightening unit has advantage of good wear-resistance, etc.
