Smooth of tinplate

- Apr 25, 2018-

The annealed steel strip is in a relatively soft state. It needs to be subjected to a slight cold rolling process, ie, smoothing, or "refining and temper rolling," and the flat reduction rate is relatively small as 0.5 to 4%.

The role of leveling:

(1) Eliminate the stress platform;

(2) partially improving the shape of the plate and giving the tin plate the surface state;

(3) The strip has a suitable hardness.
