In the year 2024 a scrap handling installation has been delivered to the most important steel group located in Asturias.
The installation consists of a fixed suspension beam with two rectangular electromagnets of dimensions 1750 x 1600 mm, specially designed for scrap handling.
This state-of-the-art electrical power supply and control equipment is equipped with a magnet current overshoot system to further improve the magnet's load capacity. In addition, the electrical equipment feeds the magnet at a constant intensity, which allows maintaining the same force level during all working hours.
In addition, it incorporates a continuous control system of all the variables of the installation, which allows to know at all times the levels of overvoltage, overcurrent, magnet temperature, among others, to ensure the status and availability of the entire installation.
This type of electromagnet has a high load capacity, up to three times higher than circular electromagnets of a similar section, improving the efficiency of the installation. Its shape allows access to rectangular containers, in which electromagnets are needed to separate low density metals.
The improved capacity of the electromagnet is due to the fact that the raised material is attracted by an external pole without the creation of the “inverted cone” shape, allowing the lifting and separation of a larger amount of material as it adheres around the perimeter.
This type of electromagnet, although it can be energized in the traditional way by any 220 V source, uses special electrical equipment to maintain its high quality and efficiency standards.
