AL-EMS ElectroMagnetic Stirrers for Aluminium Furnaces can achieve higher productivity, lower energy consumption and less dross in aluminium melting furnaces
The AL-EMS electromagnetic stirrer from ABB provides fast, contact‑free mixing of aluminium melts, improving productivity, reducing energy use, and lowering dross formation. It can be mounted on both bottom and side of furnaces ranging from 5 to 140 tons and requires only a non‑magnetic plate and about 2 m of headroom.
Installation is simple, with low‑maintenance design, compact power supply, and optional containerized solutions. The system delivers rapid temperature homogenisation, significant energy savings, and a typical pay‑back period of six to twelve months.
| Stirring speed | < 1 minute per full furnace revolution |
|---|---|
| Required headroom for installation | ~2 m |
| Temperature homogenisation time | <5 °C in 2–3 min |
| Dross reduction | 25–50 % |
| Energy savings | up to 15 % |
Typical installations achieve a dross reduction of 25 % to 50 %.
Installation needs roughly 2 meters of headroom in front of the stirrer.
