摘要: In continuous casting of steel strip, a casting pool of molten metal is supported on moving casting surfaces which are chilled to cause solidification of steel on the casting surfaces. The casting surfaces are textured by provision of parallel groove and ridge formations (11) defining V-shaped grooves (12) and ridges (13) with sharp edges (14). The depth (d) of the texture from ridge peak to groove root is in the range 5 to 50 microns and the pitch (p) between the grooves is in the range 100 to 250 microns. The casting surfaces may be peripheral surfaces of casting rolls of a twin roll caster.
