Method for the lateral compacting of slabs, which is employed in a rolling line at least upstream of the finishing rolling mill stands as an alternative to, or in cooperation with, rolling mill stands with vertical rolls, the method employing two counter-opposed compacting dies (11) supported by relative die-holder bodies (13) and associated with relative lateral edges of the slab (12) being rolled, each compacting die (11) cooperating with the relative actuation system comprising a crankshaft (15) and one element having the function of a connecting rod (18) positioned with its axis (30) on the same plane as, and perpendicular to, the axis of feed of the slab (12) and having one of its ends rotatably associated with the crankshaft (15) and its other end rotatably associated with the relative die-holder body (13), including two connecting rod elements associated with each crankshaft and with each die-holder body, at least one of the two connecting rod elements varying its length during each working cycle, said variation occuring at least during the return travel of the die-holder body. Device for the lateral compaction of slabs which employs the method as described above. <IMAGE> |
