Steel and metalworking

Blowing off steel sheet in a reversing cold rolling mill

#140.

An emulsion is applied for cooling and lubrication when cold rolling steel. If this emulsion is not removed after rolling, it can cause problems such as streaks, stains and rust on the surface of the steel. The company's existing solution failed to remove the emulsion satisfactorily. This affected the surface finish and led to deviations that were difficult to remedy afterwards. The deviations led to an increasing number of rejects, more material consumption and greater costs for the company.
