Contact cooling water treatment steel roll mill

The present study presents an overview of the qualitative and quantitative characteristics of the contact cooling water cycle at a steel hot rolling mill, where the cooling water circuit is fed with make-up water from reverse osmosis of saline water. It is concluded that the application of
