4. Electrogalvanizing sequence management

To meet the quality criteria demanded by customers, the operator needs to control the process, i.e. electrolyte stabilization, in order to optimize reactor operation. In the case of a closed batch reactor, for example, the composition of the bath changes throughout the campaign as a result of reactions that may take place within the reactor, as well as due to entrainment from upstream to downstream stations. A global approach based on the establishment of a material balance for each mineral component of the electrolyte provides the operator with a better understanding of how the [20][22] reactor works. This will enable him to define the concentration setpoints and, by the same token, the corrective actions required to maintain the system at a given operating point....
