AMepa - Electromagnetic Slag Detection (ESD) System for Molten Steel

SHARE

The Electromagnetic Slag Detection system (ESD) is crucial for ensuring the slag-free transfer of molten steel, enhancing both the yield and quality of the final product. Positioned at the bottom of a ladle, this system detects the presence of slag by monitoring voltage changes in the secondary coil caused by eddy currents induced in the outflowing molten steel. With over 30 years of experience and 300 installations supporting around 3600 ladles, the ESD 300 and ESD 400 models are a testament to AMEPA's pioneering technology in slag detection. This system automatically initiates the closure of the slide-gate upon slag detection, offering a balance between yield and quality optimization. It features advanced digital transmission for improved sensitivity and reliability, with the capability for remote maintenance, enhancing operational efficiency. The dual-channel technology further distinguishes AMEPA, allowing for detection of initial slag particles to preserve steel purity. Comprehensive reporting and smart analysis tools provide users with valuable insights for process optimization and maintenance planning.

Slag-free transfer of molten steel is critical for prime or scrap and critical for profit or loss in producing high-quality steels. Regardless of whether it is for furnaces, ladles, or distributors: Large quantities of slag must never be transferred to the next vessel.

The ESD Electromagnetic Slag Detection, positioned at the ladle bottom, sounds an alarm as soon as slag flows through and sends a signal to automatically close the slide-gate.

Developed with a background of 30 years of experience, based on 300 slag detection systems with 3600 ladles installed, the new generation of AMEPA Slag Detection with ESD 300 and ESD 400 once again sets a new benchmark for the industry.
