We supply ceramic-lined coating pots used in steel strip coating with alloys such as Zn, ZnMg, ZnAl, AlSi. These pots are fitted with air- or water-cooled channel-type inductors. They are able to produce excellent surface properties at high process speeds.

The optimal number and arrangement of inductors depend on the coating alloy and the tank geometry. In addition to this, numerous other factors, such as homogeneous bath temperature distribution, strip temperature and the melting energy necessary to compensate for the drag-out of material determine the specific plant design. Precise temperature control to ensure high temperature homogeneity is a key requirement for achieving high-grade strip surfaces and reducing dross formation.

Our plants are equipped with high-precision bath level and bath temperature control systems. The temperature control system automatically adjusts the inductor power to set the bath temperature with an accuracy of ± 1°C.
