Cold Rolling - Reduced Steam Use in the Acid Pickling Line
In the pickling line, heat escapes through evaporation from the hydrochloric acid bath. The bath is normally heated to temperatures of 95°C. It is reported that steam use can be reducedby installing a system of lids and floating balls on top of the bath.
