    At the end of the tap the levels of slag and steel rapidly reverse. Quick termination of the tap after the alarm has been triggered is necessary to prevent excessive levels of slag in the ladle.

    SDS uses a high-resolution thermal imaging camera to detect the transition between steel and slag. The dedicated thermal imaging camera has been specifically designed to survive in the harsh operating conditions and utilizes a particular wavelength to reduce obscuration caused by smoke and fume. Data is presented to the operator in real time enabling them to make informed decisions about the tapping process and the system provides clear alarm notifications.



    Suitable for a variety of applications 

    SDS is suitable for operators of secondary steel making vessels (e.g. EAF, BOF) including stainless steel and can also be used in other smelting operations Eg copper and platinum. The system can also be used to indicate freeboard height if required providing a wide field of view.


    Improved product quality

    Using the SDS has been demonstrated to improve operator response time and consistency at the end of each tap. This typically results in a reduction in slag depths of up to 25% compared to traditional methods of stream monitoring.


    Reduced downstream processing costs 

    The cost of additional downstream processing time and materials can be a significant burden on an operating plant. By controlling slag carry-over this costly downstream processing can be reduced or eliminated, improving plant throughput, product quality and operating margins.


    Automatic operation

    As the tap commences, the application dedicated software records a data log and produces a live graph for quality control. A stream tracking mechanism is included to ensure reliable operation in typical installation conditions. When slag appears, and exceeds an operator defined amount, an alarm is automatically triggered. The system is designed to ensure accurate, real-time detection of steel/slag independent of charge weight and without operator intervention.


    The Slag Detection System is AMETEK Land’s definitive solution for monitoring and reducing slag carryover in steel production facilities. It is proven to reduce slag carryover, save money and improve operator safety.

    Thermal Imaging Slag Detection System - Accurate and Rapid Detection of the Onset of Slag Carry-Over

    Our Slag Detection System simulation video demonstrates the accurate and rapid detection of the onset of slag carry-over. When slag appears, and exceeds an operator defined amount, an alarm is automatically triggered and the tap is terminated. This reduces slag carry-over, delivers improved yields, higher-quality steel and reduces costly downstream processing.
