RAMON Stopper Digital Control System

Functional Advantages 

 New one-integration oriented stopper rod mechanism ensures the high control precision. The new type crossbeam with high temperature resistance (temperature resistance: 1100℃)can be customized and supplied to avoid stopper lose control accident due to the crossbeam deformation which caused by long-term operation under high temperature environment.     

 New generation of high precision digital electric actuator, the motor precision is 65535 pulses, electric actuator linear precision is ±0.01mm, it is high temperature resistance without additional cooling and protection measures required. 

 System is quick response and constant mould level assured.

 With three control modes: auto, semi-auto and manual. 

 With functions of nozzle protection, breakout/overflow intelligent judgment and auto processing etc.

 With auto startup functional module which can reduce the length of the head slab and the quality of the head slab is improved.

 With breakout prediction joint debugging functional module, device safety is improved.  

 With molten steel vortex inhibition functional module which can restrain mould level fluctuation efficiently in casting final stage.

 With bulging compensation functional module which can restrain mould level fluctuation of peritectic steel efficiently. 

 With flocculating inhibition functional module which can reduce low carbon high quality cast product demotion caused by mould level fluctuation. 

 With oscillation compensation functional module which can eliminate the influence of mould oscillation on mould fluctuation. 

 With fault diagnosis functional module for quick positioning of fault position and cause.  

 With remote diagnosis functional module for user to check and guide the treatment remotely.
