Abstract
A process for the manufacture of billets and blooms from continuously cast steel, allowing such long products to be directly conveyed to a finishing rolling mill in a plant supplying high quality steel and/or excellent quality steel. Said process is comprising a liquid core distortion stage, concerning the casting cross section and causing the reduction of the same cross section, the perimeter remaining unchanged (equal). Said distortion occurs in the zone comprised between the point (S), last point on the casting axis (X-X) where superheated liquid is still present, and the point (L) where the casting is completely solidified (end of the metallurgical length). Preferably, said distortion is carried out between the points respectively corresponding to 10 % and 80 % of the concentration of solid grains in the fluid mass. An apparatus is described too, essentially comprising means for bringing at least one of the sectors forming the roller train (along the casting route) near the opposite one, in at least one plane containing the casting axis (X-X), in correspondence of said distortion zone.
