    Working Principle

    e-SlagCheck Ladle uses electromagnetic sensing to monitor the tapping stream in real time. 

    • A signal is generated across the tapping stream  
    • Changes in material composition affect the signal behavior  
    • Advanced digital signal processing analyzes these changes to detect slag presence instantly  

    As soon as slag appears in the stream, the signal response changes and is interpreted by the system, enabling immediate detection and response. 

    This supports faster, more precise, and more reliable control of the tapping process. 

    Easy Integration and Process Visibility 

    e-SlagCheck Ladle is designed for straightforward installation and operation, while also providing improved visibility into the tapping process. 

    • Plug-and-play sensor design for easy installation  
    • Compatible with standard slide-gate systems  
    • Minimal modification required for integration into existing setups  
    • Operator-friendly interface for straightforward use  
    • Integration with plant control systems  
    • Access to process data and monitoring tools 

    The system provides valuable insight into tapping behavior, enabling better understanding, improved process control, and more informed decision-making across operations.
