Abstract:
The present disclosure relates to a tail end squeezing prevention device for a tandem rolling mill wherein a material to be rolled undergoes rolling in N (N≥2) consecutive rolling stands. Each ith rolling stand (1≤i≤N) in the tandem rolling mill has an ith roll bender device for reducing the material to be rolled with a preset roll bender pressure. During the interval between the release of the tail end of the material being rolled from one specified jth rolling stand (1≤j≤N-1) and release from the Nth rolling stand, the tail end squeezing prevention device continuously reduces the roll bender pressure in the j+1th to the Nth roll bender devices downstream from the jth rolling stand.
