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

How Quenching Hardens Steel in Metalworking
09.08.2019· 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. How Quenching Is Executed . Common media for quenching include special-purpose polymers, forced air convection, freshwater, saltwater, and oil. Water is an effective medium when the goal is to have the steel to reach maximum hardness.
Failure analysis of re-bars during bending operations
01.10.2014· Rebars are “hot rolled” from steel billets and subjected to on-line thermo mechanical treatment in three successive stages : Quenching: Hot rolled bar leaving the final mill stand is rapidly quenched by a special water spray system. This hardens the surface of the bar to a depth optimized for each section through formation of martensitic rim while the core remains hot and austenitic.

Understanding Rolling Process in Long Product Rolling
It was first developed in the late 1500s. Hot Rolling is carried out at elevated temperature above the re-crystallization temperature. During this phase, the coarse-grained, brittle, and porous structure of the continuously cast steel is broken down into a wrought structure having finer stone size and improved properties.
