Depending on the project, hot and malleable steel will be dipped in either water or oil to cool. This brings the steel back to a solid state and often leaves it brittle. Heat treated steel can also be left to air cool. But as mentioned in the different steps of heat treatment above, the way steel is cooled will greatly affect its finished quality.

cooling water itself gets hot; before it can be used again it must either be cooled or replaced by a fresh supply of cool water. A Cooling Tower is a heat rejection device that extracts waste heat to the atmosphere by cooling a stream of hot water in the tower. This type of heat rejection is termed "evaporative" because it allows a small

2022-05-10 · In both continuous casting of steel slabs and direct chill (DC) casting of aluminum alloy ingots, water is used to cool the mold in the initial stages of solidification, and then below the mold, where it is in direct contact with the newly solidified surface of the metal. Water cooling affects the product

 · Obviously, cooling water temperature rises in heat exchangers, thus making the exchangers susceptible to CaCO3 deposition. The acid-chromate program of old inhibited scaling by reaction of sulfuric acid with bicarbonate ions (HCO3-) to convert the ions to CO2, which escape as gas. A typical pH control range was within or near to
