Digital signal evaluation and rule-based algorithms increase process reliability in clean steel production

New software makes slag readings available factory-wide.

At METEC exhibition AMEPA will present the new AMEPA Report software which automatically analyses the measured values of the slag detection sensors in the steel mill using new methods of digital signal processing. For example, problems in the area of well block, upper nozzle or slide gate of casting ladles are detected very quickly, and the measured values are available throughout the plant.

More than 300 systems of the AMEPA electromagnetic slag detection system ESD are already in use in steelworks on ladles and converters worldwide. These systems report an alert as soon as there is a danger that the slag produced in each process step will be transferred to the next vessel.

The AMEPA Report software analyzes the measured values of the ESD sensors with digital signal processing and automatically evaluates the data based on rules. On casting ladles, measured values deviating from the nominal values are detected very quickly, for example in the area of well block, upper nozzle or slide gate. This is done without taking the time to track individual value curves. This evaluation can also be used to schedule maintenance work.

All status messages are presented to the steelworker in table form, and the measurement results in graphic form. The results can be sent automatically to previously configured user groups as shift or daily reports in the form of e-mails at specific times.

As part of the increasing cross-process networking, the system stores measurement data and system results in a database. Detailed data, current and historical, is available to users in their company-wide network.

In addition, a web server makes contents of the database available within the customer network which can be accessed at any time with standard web browsers. Thus, the AMEPA Report software makes data about accompanying slag available to different user groups at any time in an adapted visualization.

The software allows the user to adapt the parameters of the ESD system to the user’s product range. Remote maintenance and access to data for online customer support by AMEPA specialists are also available.

The new software can be used for existing slag detection systems, ESD 100 S and ESD 200 from model year 2010. In this way, customers with older systems can benefit from the advantages of development in digital evaluation.
