quenching of clinker due to water spray

Quenching - an overview | ScienceDirect Topics

Quenching involves rapid cooling from the solution-treatment temperature to room temperature to suppress the reformation of coarse intermetallic precipitates and to freeze-in the alloying elements as a supersaturated solid solution in the aluminium matrix. Quenching is performed by immersing the hot aluminium in cold water or spraying the metal with water, and this cools thin sections in less ...
