Abstract
The invention relates to the pressure treatment of metals, specifically to producing a metal strip using cold deformation. A strip is consecutively drawn with back and front tension through bending devices. Moreover, the degree of deformation of a strip is regulated in each bending device by means of changing the ratio of the speed of the strip exiting a bending device to the speed of said strip entering said device, in such a way as to avoid a break in the metal, the required number of bending devices being selected on the basis of the total stretch factor of a strip and on the maximum allowable stretch factor of same. The result is increased deformation of a strip and reduced energy consumption.
