<p>Foot rolls for continuous casting which consist of at least two successive layers of assemblies of rolls (13), each assembly of rolls (13) lying substantially on the same plane, the foot rolls (13) being positioned immediately downstream of an ingot mould and immediately upstream of a discharge conveyor (11), each assembly of rolls (13) defining a geometric figure conforming to the cross section of the ingot being formed, the rolls (13) containing a stationary, cooled supporting shaft (14) secured at its ends to vertical uprights (18), the rolls (13) being supported on bearings (15) keyed to their respective shafts (14), each shaft (14) being supported and positioned on the uprights (18) and containing a first inner conduit (21a) connected to first radial conduits (23a) opening out at one end of a cooling chamber (24) within the respective roll (13), the cooling chamber (24) cooperating at its other end with second radial conduits (23b) connected to a second inner conduit (21b), which opens out in a passage (25) machined in a housing (19) that supports the terminal portions of two consecutive shafts (14). <IMAGE></p> |
