For cold rolling of thin strips, the strip geometries and the material properties must be kept within close tolerances. The precise control capability of induction heating makes it particularly significant for thin strips. Along with full heating with boosters, partial heating is used in cold rolling mills.Cold rolling mill - ArcelorMittal in Belgium,After having passed through the cold rolling mill, the steel strip is hardened. This entails that it is no longer able to be processed further. This is why, in order to make the steel cold deformable, it needs to undergo a heat treatment. This can be done in the batch annealing section or in the continuous annealing and processing line.What's the difference between hot and cold rolling mills?,27-09-2019· After heating, the strip is made of cold rolling mill and hot rolling mill.
