APPARATUS FOR LIFTING WEIR OF MENISCUS SHIELD IN THE TWIN ROLL TYPE STRIP CASTER

摘要

The present invention relates to a lifting device of a meniscus shield weir twin roll casting thin, thin twin roll In the protection and incorporation of the lifting device provided on the inclined surface of the weir meniscus shield for discharging the scum during casting; Wire rod and concluded that the weir is fixed to the guide plate; A ball joint equipped with a ball which is fastened to the other end of the wire rod, having a lower portion for receiving one end, and with a rack provided on the outside of the meniscus shield; The rack and pinion is coupled with value; Provides a meniscus shield weir lifting device of twin roll casting machine consisting of a thin plate is connected to the pinion fixed to the drive motor via the gearbox having a deceleration function. ; Accordingly, the present invention is lifted Since the main structure of the device are installed outside the high temperature places it does not have the gear or shaft deflection caused by thermal deformation adhere smoothly and precisely the weir can be more precise and elevating control, and therefore the mechanical tolerances due to the backlash of the gear or even remove the scum it can precisely control the exhaust removal and contamination prevention than to give to produce a high-quality sheet metal products.
