SYSTEM FOR THE REPLACEMENT OF ROLLING-MILL ROLLS

摘要

A pair of rolling-mill rolls, to be replaceably inserted in a rolling-mill stand, is mounted upon a skid carried parallel to the rolling direction and shiftable bodily in the horizontal transverse direction to carry the rolls into the stand. The members of the skid are provided with hydraulic ducts connected to positioning cylinders on the lower roll for spacing the rolls apart.
