ELECTRIC STOPPER DRIVING (HIGH PRECISION STOPPER-ROD MECHANISM + ELECTRIC SERVO-ACTUATOR) stopper-rod flow control billet, bloom, slab For several years, most steel plants worldwide rely on expensive and advanced sensors and controllers for their mould level control. Today, it is widely accepted that the stopper driving system is as important as the measurement itself for ensuring a performant mould level control and for giving reliability to autostart. The famous DEM electric servo-actuator provides : a 100% electric solution a stopper-rod speed up to 100 mm/s reaction speed 3 to 4 times quicker than      hydraulic actuators extremely low maintenance over 440 units have been installed worldwide The MQS high-precision stopper mechanism provides : double ball bearing guiding sealed casing for no maintenance       specially designed to take advantage of the DEM      electric actuator's high performance flow precision required for Autostart over 350 units have been installed worldwide Main advantages of DEM-MQS : higher precision in the control of steel flow to the      mould reduction of downgradement due to      mould level variations faster response to surges reduction of periodical fluctuations in the mould constant performance increased reliability on Autostart maintenance significantly reduced high safety for the operators Examples of references : Sollac, Ugine, Unimetal, Acerinox, Acciai Speciali Terni, HKM, Lech Stahlwerke, Stahlwerke Thuringen, Jindal, Musco, Posco, Riva Taranto, Acroni, British Steel, Fafer Usinor, Cockerill, Atlas Steel, Sidbec Dosco, Macsteel Quanex, Allegheny Ludlum, etc. Contact us
