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.

GREEN STEEL - DECARBONISATION
Supporting the de-cabonisation process in steel production by continuous process control and optimisation, energy savings and emission reduction.
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. By using additional region of interests (ROI) together with a secondary thermal imaging camera integrated into the system, optional features such as stream position or freeboard height can also be integrated providing advanced process monitoring and control.
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.
Slag Detector
The Slag Detection System is 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.
