    How Quenching Hardens Steel in Metalworking

    09.08.2019· Quenching is a rapid way of bringing metal back to room temperature after heat treatment to prevent the cooling process from dramatically changing the metal's microstructure. Metalworkers do this by placing the hot metal into a liquid or sometimes forced air. The choice of liquid or the forced air is referred to as the medium.

    The Hot Rolling Process California Steel Industries

    As with the roughing mill’s descaling system, for some thinner-gauge, wider, and/or stiffer products, the low-pressure header is disabled to conserve heat for rolling. In part because further descaling is not particularly practical once finish rolling begins, the #2 Scale Breaker is the last opportunity to remove oxidation before the finished hot-rolled strip is coiled. Typically, the descaling
