Automatic Mould Level Control System for Slab and Bloom Casters

Automatic Mould Level Control System for Slab & Bloom Casters

Purpose and main functions:
System designed for automatic stabilization and control of a preset level the molten metal in the mould of continuous casting machine and has the following features:
  • automatic hardware diagnostics system;
  • auto-start the strand;
  • automatic control of the level of metal in mould;
  • control of casting process parameters;
  • collect, display and recording in the main archive system parameters;
  • develop warning and alarms;
  • prevention of clogging tundish stopper;
  • automatic suppression backlash in the stopper mechanism;
  • emergency closing of the stopper;
  • transmission and reception parameters in APCS CCM.

MLS- - Embedded metal level sensor measures the level of the molten steel in the Mould.
MLS - Mobiled suspended metal level sensor on a tripod - measures the level of the molten steel in the Mould (in case MLS- is damaged).
MPS - mold position sensor. DAP - data acquisition & processing MLS- and MPS Sensors.
MLC - mold level controller.
MLC-U Mould Level Controller.
SA - Stopper Actuator moves the Tundish Stopper.
FCU - actuator control unit.
LCP - Level Control Panel is the main control and display unit of the System.
WSD - Workstation Diagnostics is designed for adjustment of parameters, diagnostics of hardware and archiving of the main process parameters.
EWS - Engineering Work Station is designed for provide remote access to Controllers and Computers of the System.
