9th ECCC European Continuous Casting Conference – ECCC 2017

The paper shows the long time trial of edge type of the electromagnetic VUHZ Mold Level Measuring System (MLM System) on Thin Slab Caster equipped with Electro Magnetic Brake (EMBR). Trial was realized in Rizhao China on Primetals ESP (Endless Steel Plant). Three MLM systems (X-ray, electromagnetic edge and suspended types) simultaneously were used for measurement of the steel level in the mold at the same time. Obtained results and trends confirmed the suitable usage of edge type of electromagnetic MLM system on Thin Slab Casters from the point of the wide detection range, good similarity with other MLM systems, stopper regulation, short and long time fluctuation, no interference from EMBR and last but not least sensor installation in limited space on the mold upper part. Some of benefits of edge type of electromagnetic MLM systems seem to be important especially on ESP: - Ready to cast: fast installation of sensors on the mold, one point checking of function, no necessity of calibration, permanently installed on the mold to measure steel level during the whole casting sequence - Steel level detection method: measuring of the true steel level without slag and casting powder - Fast measuring signal proceeding in the digital evaluation unit suitable for high speed casting, low noise, high signal stability - Easy maintenance, long life time of MLM system, repairable sensors, overflow riding out - Harmless
