Abstract
Homogenous surfaces and minimal coating thickness at high production throughput are the targets in hot-dip galvanizing production. Electromagnetic strip stabilization became a proven solution with in the meantime over 33 installations of the EMG eMASS® system. Over-coating is substantially reduced and eMASS® ensures a flat and stable strip between the air knives. The benefits of an electromagnetic strip stabilization solution heavily depend on the stabilization performance and the control algorithms, but also on the crucial question of the integration of the system into the production line. The combination of eMASS® with all major air knife types and with various special solutions made it the most flexible and successful strip stabilization system today available on the market. The paper concentrates on results and experiences, but also on constraints and challenges of eMASS® projects. Firstly, installation examples and specific solutions will be presented by real world projects, concentrating on challenging requests. This includes its combination with auxiliary systems like air knife wiping equipment or baffle blade control systems. Secondly, vibration reduction and crossbow elimination results as well as long term operation data will be summarized. And thirdly the lessons learned, based on a recently performed customer survey, will be highlighted. The paper shall provide future users key arguments for deciding on and planning of industrial strip stabilization projects.
