AMETEK Land will exhibit at AISTech 2018, May 7-10 in Philadelphia, Pennsylvania, USA, Booth 2208.  

With over 70 years of steel industry application expertise, AMETEK Land offers the SDS-E Slag Detection System as a proven solution for accurate and timely detection of slag carryover in the steelmaking process. 

“AISTech, the steel industry’s premier technology event, is the ideal platform for us to launch our SDS-E technology to individuals involved in the production and processing of iron and steel in the North American market,” comments Ben Wileman, Division Vice President of Sales and Marketing for AMETEK Land and AMETEK Surface Vision.

“There are major benefits for steel producers to use this technology, as a fast slag detection response allows plants to significantly reduce slag carryover. That results in improved yields, higher-quality steel, and a reduction in costly downstream processing. There are additional benefits as well in reduced ladle refractory wear and improved operator safety,” he adds.

At the end of the tap, the levels of slag and steel rapidly reverse. Quick termination of the tap after an alarm has been triggered is necessary to prevent excessive levels of slag in the ladle. AMETEK Land’s SDS-E uses a high-resolution thermal imaging camera to detect the transition between steel and slag. 

That dedicated thermal imaging camera is specifically designed to survive in the harsh operating conditions and utilizes a particular wavelength to reduce “blackouts” caused by smoke and fume. Data presented to operators in real time enables them to make informed decisions about the tapping process.

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

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

As the tap commences, application-dedicated software records it, using a stream identification algorithm, and produces a data log and 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 automatically triggers. The system is designed to ensure accurate detection of steel/slag that is independent of charge weight and without operator intervention.

Suitable for operators of secondary steel making vessels (e.g. electric arc furnaces, basic oxygen furnaces) including stainless steel, AMETEK Land’s Slag Detection System is the 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.
