Abstract

In a process for galvanising a strip (1) the strip (1) is continuously coated with zinc, is then, so as to form a Zn-Fe layer, subjected to a heat treatment in a continuous furnace (10, 11), followed by on-line monitoring of the zinc layer, the iron content of the zinc layer being measured and the galvanising operation being controlled as a function of the iron content of the zinc layer. In order to be able to manufacture a strip (1) having a defined layer structure ensuring uniform quality, a value of the iron content of the Zn-Fe layer is determined as a reference input variable, the actual value of the iron content of the Zn-Fe layer is compared with the reference input variable and any system deviation is compensated via a controller (19) by means of a change in the continuous furnace (10, 11) heating output which serves as the manipulated variable (Fig. 1). <IMAGE>
