Title: (EN) Two stand tandem for rolling line
Abstract:
(EN) Tandem with two reversible four-high rolling stands (14a, 14b) for the cold rolling of thin strip up to 0.18 mm, advantageously from 0.18 to 1.2 mm, comprising at least a first (12a) and a second (12b) drawing reel, means to heat the rolls and the lubricating oils, a control and command unit, a first, usual lubrication system (17), the working rolls (15) being associated with replacement rolls (115), the stands (14a, 14b) including a first working condition with the working rolls (15) and at least a second working condition with the replacement rolls (115), wherein below the stands (14a, 14b) there is a first (20a) and a second (20b) collection tank to collect the lubrication fluid, there also being a second finishing lubrication system (18) which can be activated in alternation with the first system (17), the first (20a) and second (20b) collection tank being equipped with switching means (21) whose command means (22) are controlled by the command and control unit (31), each of the switching means (21) being equipped with at least two ways (30a, 30b) which can be activated in alternation, a first (28a) and a second (28b) containing reservoir tank cooperating respectively with a first (24a) and a second (24b) circulation pump, each of the pumps (24a, 24b) feeding the respective first (17) and second (18) lubrication system.
