Products - Slag Detection System

      The Slag Detection System is a real-time control system that is used in Steel Plants for detection of Slag in the molten metal during the casting of steel. The Slag is the layer of impurity that floats on top of the molten metal and must be prevented from mixing into the steel during steel casting to maintain the quality of the steel. The vibration level of the metal flowing through the Laddle opening is different for pure metal and for Slag. An accelerometer is used as sensor for vibration level measurement. This signal fed to a VMEbus controller for high-speed acquisition and analysis. The system has some digital I/Os for interlocks and Laddle Gate opening control. The level of opening of the Laddle Gate determines the quality of the Steel.

    The entire control application is written in 'C' and runs on a real-time operating system OS9. The hardware is based on VMEbus technology and uses a Motorola MC 68060 based CPU. A Microsoft Visual C++ 6.0 based GUI allows system configuration and data visualisation.
