Annealing of Cold Rolled Steel – IspatGuru0183;32;Annealing of Cold Rolled Steel. The cold rolling of steel is done at temperatures below the recrystallization temperature. During cold rolling process the reduction in thickness is due to plastic deformation which occurs by means of dislocation movement. Steel gets hardened because of the buildup of these dislocations.
Cold rolled coils have received an additional treatment after it has been hot rolled, pickled and oiled. The coils are moved into a series of rollers to lower its thicknesses and to have uniform surface smoothness. The process is done at room temperature. Cold rolled coils can then be further annealed to soften the steel.
Nov 04, 2017 · CRCA steel means cold rolled close annealed material. It means the steel is cold rolled and then annealed in close furnace. CRCA steel has better mechanical properties compared with hot rolled steel that neither undergoes cold rolling nor with close annealing.
Because cold rolling significantly increases material hardness, making forming difficult, annealing is performed to improve ductility by inducing a recrystallized structure in the steel. As the annealing process, coils are piled and covered by the box and annealed and this is called the batch annealing.
