Abstract:
A rolling plant for rolling a continuous billet (15) fed from a billet-heating furnace (10) set upstream of a roll train, in which in the space between the furnace (10) and a first stand (11) of the roll train is provided a system of welding the head of a first billet (14) coming out of the furnace (10) along an axis (12) of exit from the furnace to the tail of a second continuous billet (15) that is undergoing rolling along a rolling axis (13), characterized in that said system comprises downstream of said furnace (1), in combination and succession:(a) a descaler (16), a pair of interspaced cropping devices (17, 18); (b) a mobile welding machine (19) mounted on a trolley (19A), which can be translated forwards and backwards on rails (20), and provided with two pairs of yokes (21, 22) set opposite to one another, respectively upstream and downstream relative to one another; (c) a mobile deburring machine (23), said descaler (16) being provided along the axis (12) of exit of the billets from the furnace (10), whilst the welding machine (19) and the deburring machine (23) are provided along the rolling axis (13) which is interspaced and parallel to the axes (12, 13); and (d) a translator (26) for the billets (14) coming out of the furnace (10).
