Abstract

1454930 Universal rolling mills NIPPON KOKAN KK 16 Aug 1974 [4 Sept 1973] 36084/74 Heading B3M In a universal rolling mill housing, each chock of each of top, bottom, and vertical rolls is provided with a pair of roll gap adjusting wedges arranged adjacent the inner surface of a housing window, each wedge being adjustable in the direction of the axis of its associated roll. The housing construction also facilitates roll removal. Figs. 1 and 2 show a mill in which top and bottom rolls 1, 2 have chocks 6, 6<SP>1</SP>, 7, 7<SP>1</SP> pivotally mounted in blocks such as 46 slidable in grooves 47 in the housing. The chocks bear through mating cylindrical or spherical surfaces on pressure members 31, 31<SP>1</SP>, 3111, 31<SP>111</SP> which contact the wedges 11, 11<SP>1</SP>, 12, 12<SP>1</SP>, 13, 13<SP>1</SP>, 14, 14<SP>1</SP> (some not shown). The wedges are adjustable by lead screws 15, 15<SP>1</SP>, 16, 16<SP>1</SP>, 17, 17<SP>1</SP> rotatable by motors and reduction gears. For removal of these rolls, the top part of each housing is a beam 10, 10<SP>1</SP> which after removal of a pin 49, 49<SP>1</SP> by jack 37<SP>1</SP> is pivotable through 90 degrees by a jack 29, 29<SP>1</SP>. The upper roll balancing devices 30, 301 have rods 30<SP>11</SP>, 30<SP>111</SP> ending in T-pieces so as to be engageable with or disengageable from chocks 6, 6<SP>1</SP> by rotation. One end of each roll 1, 2, is axially adjustable, and the other is axially free (Fig. 9, not shown). The vertical rolls 3, 4 are mounted in chocks 8, 9 slidable between yokes 5a, 5a<SP>1</SP>, 5b, 5b<SP>1</SP> on the housing. These chocks bear through pressure pieces (not shown) against wedges 22, 22<SP>1</SP>, 23, 23<SP>1</SP> movable vertically by motors, reduction gears and lead screws. Each wedge has a cut away part enabling the chocks and rolls to be withdrawn laterally when the wedges are appropriately positioned. Fuid pressure balancing devices are provided for the vertical rolls (see Fig. 3, not shown).
