In terms of physical characteristics, cold-rolled materials are typically harder and stronger than standard hot-rolled counterparts. As the material is deformed at a lower temperature, the steel's hardness and resistance against deformation get increase due to work hardening.
A smooth & bright surface finish can be obtained due to fewer chances of surface oxidation.
The cold rolling is generally done using a 20-Hi-Sendzimier cold rolling mill. This type of rolling mill offers the advantages of great rigidity, bearing the rolling force uniformly along the entire width of the rolling mill through the backing bearing, and therefore the longitudinal and lateral dimensional accuracy of the sheet/ strip is high.
The CR Annealing & Pickling line is on environment-friendly LPG fuel with better temperature control, associated with Electrolytic and Acid Pickling with very high control on the pickling process.
