Casting surface for a continuous metal casting mould with movable walls

摘要

The ingot mould, e.g. for molten steel, consists of two cooled rollers (2) set with a gap between them forming the moulding surface. Each of the rollers has a series of circular or elliptical recesses (7-10) formed by surface lobes (3-6). The lobed surface has a perimeter which is 1.1-1.5 times greater than an equivalent roller with a cylindrical surface.
