Plant for rolling long products from billets and blooms coming from a plurality of continuous casting lines

A plant for rolling long products from billets and blooms coming from at least two continuous casting lines, each said at least two continuous casting lines including a shears, said plant comprising a temperature-equalizing furnace disposed downstream of the shears and comprising an inlet in the temperature-equalizing furnace downstream of each said at least two continuous casting lines, an intake roller conveyor downstream of each said inlet, fixed supports defining a zone of equalization of the temperature of the billets and blooms, a discharge rollery conveyor disposed in an intermediate position in said temperature-equalizing furnace between said intake roller conveyors, said discharge roller conveyor including discharge rollers supported by a roller support device, said roller support device including means for transversely and vertically displacing said discharge rollers, internal traversing means for transferring the billets and blooms from said intake roller conveyors to said fixed supports and for moving the billets and blooms on said fixed supports to said discharge rollers of said discharge roller conveyor, and an outlet in the temperature-equalizing furnace downstream of said discharge roller conveyor.
