<p>A method of producing a metal slab comprises continuously casting a metal strand in a continuous casting mould having two broad face plates (1) and two end plates (2), the latter being shaped so that each of one pair of faces (10) of the strand includes a portion (11) of concave form, and before the strand is fully solidified, applying rolling forces to the other pair of faces (9) to reduce the thickness of the strand to the required thickness and to cause the concave portions (11) to distort outwardly so that that pair of faces (10) becomes substantially flat and mutually parallel. Conveniently, each concave portion (11) is flanked on either side by a chamfered corner portion (12) which also distort outwardly upon the application of rolling forces to the faces (9) so that the faces (10) become substantially flat, mutually parallel and are at 90° to the other pair of faces (9).</p> |
