ABSTRACT:
Multi-stand rolling mill with a device for protection against overloads due to irregularities in the feed of the rolled product, comprising a kinematic chain for transmitting motion to the stands from at least one drive means, with an individual drive shaft for each stand and a coupling between each of the drive shafts and the respective rolling stand. The couplings are electromagnetic couplings. Detector means are provided for detecting irregularities in the rolled product feed. The latter are associated with at least one of the stands, preferably the last and are operatively connected to at least one group of the couplings, and preferably all, to simultaneously operate the group of couplings, and preferably all the couplings, to cause all the rolling stands to be simultaneously disconnected from the kinematic chain.
