Abstract

PURPOSE:To greatly extend the roll life, and to maintain the superior shape-controllability for long hours, by fitting the movement-controllable moving part into the hollow part ranging over entire length of a pair of backup rolls, and by constituting so as to be possible to change the rigidity of the backup roll. CONSTITUTION:In the four-high rolling mill provided with a pair of backup rolls 11, 11, contacting with entire length of the work rolls 10, 10, to roll the rolled material 1, the longitudinal hollow part 12 is formed inside of each of a pair of backup rolls 11, 11, and the moving shaft 13 is freely slidably fitted into the hollow part 12, and besides, the outside end of the moving shaft 13 is borne by the chuck shaft 15 provided with the bearing 14; hereby, the shaft 13 is constituted so as to be movable by the external operation. The hollow part of the roll 11 keeps the necessary rigidity, and eliminates the uncontacting part between the rolls 10, 11, and prevents generation of the roll damage like as the sporing, etc.
