Managing Water Contamination to Maintain Effective Steel

Moisture is omnipresent in steel mills. It comes primarily from mill cooling water entering the circulating oil system and from simple condensation during mill downtime. Although necessary to reduce the extreme heat generated in the processing of steel, water is among the most destructive contaminants to the circulating oil system.

Steel Treating of steel Britannica

The heads of rails are sometimes heat-treated in-line by induction heating coils, air quenching, and tempering by a controlled use of the heat retained in the rail after quenching. Heavy-walled structural shapes are sometimes water-quenched directly after the last pass at the rolling mill and also tempered by the heat retained in the steel.
