ABSTRACT:
Crystallizer, or inner portion, of a mould having a lengthwise curvature for continuous curved casting of thin slabs (20), the crystallizer comprising an outer, or extrados, plate (12), an inner, or intrados, plate (11) and lateral narrow plates (13s-13d) having inner faces (16) defining a casting section (14), the lateral narrow plates (13s-13d) having their inner faces (16) inclined in such a way as to impart to the downflow channel a tapered conformation which reduces the width of the casting section (14) in the direction of feed of the thin slabs (20), both the extrados (12) and intrados (11) plates being curved lengthwise and containing in their inner upper central portion respective frontal extrados (15) and intrados (115) hollows, the upper part of the inner face (16) of the lateral narrow plates (13s-13d) comprising a bevel (17) which faces towards the intrados plate (11) and is progressively reduced to zero in the vicinity of the level of the lower end of the extrados (15) and intrados (115) hollows.
