Title: (EN) Two stand tandem for rolling line
Abstract: front page image
(EN)

A tandem with two reversible four-high rolling stands (14a,14b) for the cold rolling of thin strip to 0.18 mm, advantageously from 0.18 to 1.2 mm, includes at least a first (12a) and a second (12b) drawing reel, mans to heat the rolls and the lubricating oils, a control and command unit, and a first 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). 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). Each of the first (20a) and second (20b) collection equipped with switching unit (21) whose command unit (22) are controlled by the command and control unit (31), each of the a switch (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.
