Cold rolling mill for thin and foil strip

摘要

Cold rolling mill for thin and foil strip has at least one four-roll stand (1), at least one wind-off reel (6) and at least one wind-up reel (8). It is characterised by a horizontal arrangement of the rolls (12, 13; 16, 17), horizontal application of the screw-down forces (F) and the bending forces (FB) to the ends of the rolls; a vertical passage (a) of the rolled strip (9) through the rolling gap (18) between rolls (12, 13), and an arrangement of the multi-roll stand, wind-off reel and wind-up reel in respective planes (2-2, 5-5, 7-7) of a building (37) or framework which lie one above the other. The working rolls (12, 13) and/or backing rolls can be shifted axially to match strip width. Two wind-off and wind-up reels are provided for pack rolling, esp. double rolling thin and foil strip. Oil or emulsion coolant and lubricant is supplied from boxes (23) and chambers (40). A catch-pan (24) is located beneath the rolls. A trolley (27) with saddle pairs (28, 29) operates in the upper plane (5-5) and transports coils (30) from a high-rack store (31) to the wind-off reel and takes away empty spools (21) to a hoist (33). A similar trolley (27) operates in the lower plane (7-7) for the wind-up reels.
