<p>A process for manufacturing steel long products provides for starting from a continuous casting step (1) with liquid core reduction, followed by induction heating (2) without interruption until the end of a rolling step (4) in a plurality of stands. The blooms or billets (10) subjected to such a process have initial thickness in the range between 120 and 400 mm and a high "mass flow" passing in the time unit at the outlet from the continuous casting, as well as an average temperature in the cross-section which is higher than the surface temperature, being in the core or inner middle region higher by 100‹C than on the surface, that is of about 1200‹C. A plant for carrying out such a process is also described. ® KIPO & WIPO 2008</p> |
