ABSTRACT:
Assembly to wind-unwind thin slabs which cooperates with a continuous casting plant (11) producing thin slabs (12) and is positioned on the same axis as that plant (11), a heating and temperature-equalization furnace (17) being included upstream of the winding-unwinding assembly (10), at least one pair of drawing rolls (23) cooperating with the winding-unwinding assembly (10), which comprises two coiling-uncoiling units (20a-20b) positioned circumferentially equidistant from, and on, a base plate (21) able to rotate about a substantially central vertical axis, one of the units (20a-20b) taking over alternately the position and function of the other unit (20a-20b) and viceversa, each coiling-uncoiling unit (20a-20b) being equipped with its own lead-in guide (26) and powered rolls (28), the powered rolls (28) being coplanar and positioned below the thin slab (12) and cooperating with a curvature-imparting roll (29), which can be moved from a position of cooperation with, and between the powered rolls (28) to an upper position when a coiled roll (33) has been fully coiled, the curvature-imparting roll (29) cooperating with an actuator (32) that adjust its pressure towards the powered rolls (28), the actuator (32) being associated with an arm (30) that supports the curvature-imparting roll (29), the lead-in guide (26) lying on the same plane as the plane of feed of the thin slab (12) and as the upper side of the powered rolls (28).
