In bar mills, directly after the last rolling stand, the bar passes through the Cooling System achieving a short and intensive cooling of the surface. Because of the reduction in the temperature at a rate higher than the critical rate for martensite quenching the surface layer of the re-bar is converted to a hardened structure while the core ...

In materials science, quenching is the rapid cooling of a workpiece in water, oil or air to obtain certain material properties.A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favorable, and kinetically ...

Quenching is a stage of material processing through which a metal is quickly brought down to room temperature from a high temperature by rapid cooling. Quench hardening is a mechanical process in which steel and cast-iron alloys are strengthened and hardened. Quenching and tempering provides steel with high strength and ductility.
