eMASS
electro-Magnetic Strip Stabilization
EMG-eMASS is an electromagnetic damper system that reduces strip oscillation in high-speed production lines in the steel industry. It is mainly used in hot-dip galvanizing plants.
EMG-eMASS is installed right on the air knife device, which blows off the liquid zinc layer. The air knife device operates at constant pressure. As a result of strip oscillation between the two knives, inequalities in the zinc layer thickness occur across the strip width and along the length. Thus, a reduction in the level of oscillation provides a more even zinc layer.
The zinc consumption for achieving a specified zinc layer thickness is reduced and at the same time the customer requirement for a homogeneous surface is perfectly reflected. Further, the production speed can be increased in many applications without any negative influence on the coating quality.
