Abstract

PURPOSE: To form the rolled material in good shape free from the camber, by giving an offset to the center axes of a couple of work rolls from the plane connecting the center axes of adjoining rolls, and by arranging the roll chock pusher for pressing above-stated work rolls respectively to the chock holder.
CONSTITUTION: At the rolling mill provided in its housing 8 with at least one couple of work rolls 2, 3, and the chocks 13, 14, for holding these work rolls 2, 3, an offset is given to the center axes of the work rolls 2, 3, from the plane connecting center axes of the intermediate rolls 4, 5, to opposite sides, that is the roll 2 to the material 1 feed-in side and the roll 3 to the run-out side; hereupon, the work rolls 2, 3, are held by the chocks 13, 14, which are pressed to the material 1 feed-in side and to the run-out side by the directly acting cylinders 17, 18, internally installed in the chock holders 15, 16, arranged within the housing 8; the circumferential speed of the roll 2 is made faster than that of the roll 3. By the present rolling mill, the rolled material in good shape free from the camber can be obtained without damaging the operatability.
