Process characteristics of cold rolled strip
Jun 05, 2017

① When the strip is rolled in cold condition, it must be softened by intermediate annealing and restored to the plasticity in order to continue rolling. [2]

② The strip slab must be removed before rolling to ensure the surface finish and reduce the wear of the roll.

③ The tensile rolling ensures the good flatness of the strip, the thickness deviation of the strip is controlled, and the rolling pressure is reduced, which is advantageous to the rolling of thin specification products.

④ By adopting process cooling and lubrication, it is easy to control the temperature of roll and strip, reduce the friction between roll and strip and reduce rolling pressure, which is advantageous to flatness control and prevents the sticking roller of strip.
