(1) with technological lubrication and cooling, to reduce the deformation resistance of the rolling and cooling roll;
(2) the tension of rolling, in order to reduce A242Gr1 cold strip deformation resistance and keep the stability of rolling process. By using the average unit values for material yield strength by 10% ~ 60%, generally no more than 50%;
(3) A242Gr1 cold strip rolling process by rolling. Due to cold work hardening material, when 60% ~ 80% of the total deformation, deformation becomes very difficult to continue. For this to be the intermediate annealing, make A242Gr1 cold strip softened after rolling to proceed. In order to get the requirement of the thin strip, the intermediate annealing may be for many times. Between the intermediate annealing is called a rolling process of rolling. A242Gr1 cold strip annealing in a continuous annealing furnace with gas protection or bell type annealing furnace in (see manufacture with annealing).
A242Gr1 cold strip cold rolling strip steel, the minimum thickness is 0.05 mm, cold rolled foil can be up to 0.001 mm.
