Abstract

PURPOSE: To quickly practice the rearranging work for upper and lower work rolls without interrupting the rolling process, by fitting heads of new upper and lower work roll chocks respectively into the fitting holes provided in the old upper and lower work roll chocks, and by horizontally moving new and old upper and lower work roll chocks.
CONSTITUTION: At rearranging the rolls, the spacers F, F are inserted between used old upper and lower work roll chocks C, C and E, E; and then, the roll balancing cylinders 7, 8 are withdrawn into the chocks E, E. Then, new upper and lower work rolls B", D" are moved from their stand-by positions horizontally in order to fit the heads 3, 4 into the fitting holes 5, 6 of the rolls B, D; hereby, the new and old rolls are united. Then, the spacers F, F are removed from the gaps berween the chocks C, E and C, E on the side of fitting holes 5, 6; the spacers F, F are interposed between new and old upper and lower rolls B, D and B', D' respectively only on one side for upholding the upper rolls. Then, rolls B', D' are horizontally pushed out, the chocks C, C are supported by cylinders 7, 8 and the sapcer F is pulled away. The rolls B, D taken out of the stand are transparted by cranes, etc., to a prescribed place.
