Electromagnetic Metal Level Sensor in a Billet Mold

Resumo

A new electromagnetic metal level sensor for a billet mold is considered in comparison with radioisotope level sensor. Comparative characteristics of the sensors in the process of casting with oil were obtained during demonstration testing of electromagnetic sensor at two metallurgical plants. In the process of operation, it was shown that electromagnetic metal level sensor has somewhat better characteristics as compared to radioisotope sensor. Utilization of electromagnetic sensor instead of radioisotope sensor allowed reducing the fluctuations of metal level and withdrawal rate in comparison with stabilization based on the radioisotope sensor at both plants.
