Abstract
The mold has movable sidewalls (13) to adjust the width of the slab and an enlarged casting chamber (11) extending along the length of the crystallizer of the mold (10). Located immediately downstream of the mold (10) are containing plates (24) and transverse rolls (18) defining a possible first assembly (19) of rolls, a second assembly (28) of rolls and a third assembly (29) of rolls. The casting chamber (11) has an enlargement provided by a central curve defined by a first equivalent radius R, the central curve at the inlet (16) of the casting chamber (11) being defined by the specific first equivalent radius R' and by a width L of at least 500 mm. with a value of the lateral half-enlargement A between 30 mm. and 90 mm., the casting chamber (11) comprising within its length a first segment (26) and a terminal segment (27), a zone of curved connection (23) being included between the first segment (26) and the terminal segment (27), the terminal segment (27) being equal to between about one quarter and one sixth of the overall length of the crystallizer (10), the terminal segment (27) comprising a first terminal portion (27') defined by the respective curved connection zone (23) and a second terminal portion (27'), the second terminal portion (27') having a constant section of its passage with a lateral half-enlargement B having a value between 1 mm. and 12.5 mm. and defined by a central curve with a specific first equivalent radius R'.
