Abstract
The device comprises two parallel and rotating rolls (3) separated by a casting space, and two lateral closure walls (4) applied in a leaktight manner against the ends of the rolls (3) and lined with insulating refractory lining (5). Each lateral wall (4) is of the 'negative insert' type. Refractory leaktight gaskets (6), consisting of consumable flexible bands, are interposed between the front faces (3a) of the rolls and the lateral walls (4) and run, during casting, at the same speed as the rolls (3), by virtue of suitable entrainment elements. The gaskets (6), unwound from feed reels, prevent infiltration of molten metal between the front faces of the rolls (3) and the lateral walls (4) and thus reduce the risk of jamming of the device.
