Regulating the Coil Stress by Adjusting the Rigidity of the Winding Drum

Resumo

The sources of defects associated with stability loss of cold-rolled strip coils are established. The influence of the winding-drum structure in cold-rolling mills on the stress–strain state of the coils, both before and after removal from the winding system, is analyzed in detail. The possibility of modifying the stress–strain state of the coils by regulating the rigidity of the winding drum is considered. Recommendations are made regarding the selection of the winding technology for rolled strip.
