ABB EM Stabilizer improves coating quality and zinc savings for galvanizing lines. ABB EM Stabilizer uses a non-contact electromagnetic strip stabilizer to reduce vibrations and strip shape problems such as cross bow in galvanizing lines. ABB EM Stabilizer's state-of-the-art control system has robustness and is optimal for all strip dimensions, enabling improved quality of the coating layer and reduced overcoating.
The EM Stabilizer is a non‑contact electromagnetic strip stabilizer designed for galvanizing lines. It reduces strip vibrations and shape problems, improving coating quality and lowering zinc consumption. The system includes magnet modules, power and control cubicles, a cooling water station, and an ABB Process Monitor for real‑time visualization.
Installation can be performed on new or existing lines, either mounted on the air‑knife structure or on an overhead rig. Technical specifications such as strip speed, power consumption, and environmental limits are provided, along with plant trial results showing significant vibration reduction and coating uniformity.
