Stable strip in hot-dip galvanizing plants

eMASS electromagnetic strip stabilization gives targeted control of strip oscillations and allows high galvanizing quality without minimizing the production throughput. Furthermore, the use of eMASS electromagnetic strip stabilization gives significant zinc savings in all hot-dip galvanizing plants. eMASS thus offers a high potential for significant cost reduction in the production of hot-dip galvanized sheet metal.

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.
