Abstract (en)
Rolling plant (10) and method for producing a strip (P) starting from a slab (50) having a certain starting thickness, comprising at least one walking beam heating furnace (16) configured to heat at least the slab (50) to a starting temperature, and a rolling train (25) operatively disposed in line with at least one roughing stand (23) and configured to reduce the thickness of an intermediate rolled product (51) at exit from the roughing stand (23), until the final strip (P) is obtained; the rolling train (25) comprising at least one pre-finishing stand (26) for obtaining a pre-finished rolled product (52), and a plurality of finishing stands (31) for obtaining the final strip (P); the plant (10) comprising load cells (40) directly associated with the pre-finishing stand (26) for detecting the rolling force applied on the pre-finished rolled product (52), a rapid heating device (28), interposed between the pre-finishing stand (26) and the finishing stands (31), for heating the pre-finished rolled product (52), and a command and control unit (44) connected both to the load cells (40) and also to the rapid heating device (28) and configured at least to selectively activate the latter (28), at least as a function of the rolling force detected by the load cells (40).
