The overall water usage of an average steel production site, however, shows that little water is actually consumed. Most of the water is evaporated or leaves the site as part of the waste and by-products (such as sludge).

Steel Treating of steel Britannica

Steel Steel Treating of steel: In principle, heat-treating already takes place when steel is hot-rolled at a particular temperature and cooled afterward at a certain rate, but there are also many heat-treating process facilities specifically designed to produce particular microstructures and properties. The simplest heat-treating process is normalizing.
