Abstract

PURPOSE: To shorten the time requirement of the exchanging work for an old roll with a new roll, and to improve the working rate of the rolling mill, by pushing new upper and lower work rolls in different diameters placed upon a table on one side of a mill housing into the housing, and by pushing used upper and lower work rolls in different diameters out onto a table installed on another side.
CONSTITUTION: New large and small work rolls 12', 16' a new intermediate roll 13', and new roll chocks 18', 29' are arranged on a table 38. The wheels of the small diameter work roll chock 18' are put on the rails 25 attached to a mill housing 19, and then, the upper and lower roll axes are set parallel by using distance pieces 43. A table 39 is arranged at a prescribed position, chock clamps 28, 35 are released, and chocks 18, 29 are brought down by the rams 26, 27, 33, 34 until the wheels 24, 30 come upon the rails 25, 31. Hereupon, a distance piece 44 is inserted between the old work rolls 16, 12. Next, new rolls 12', 16', 13' are pushed toward the housing 19 by a cylinder 42 and are set at prescribed positions within the housing 19; and at the same time, old rolls 12, 16, 13 are pushed out upon the table 39. The old rolls together with the table 39 are taken away, the chocks 18, 29 are clamped, and hereby, the exchanging work for rolls is completed.
