Abstract:
A plate (5) for lateral containment in apparatus for continuous casting, comprising:at least one insert (8) of a ceramic material; a plurality of joints (11) for thermal expansion, the plurality of joints being constituted of a ceramic fibrous material; a first casting (9) of a silica-alumina material containing ceramic fibres; a second casting (10) of a silica-alumina material having a high content of ZrO2; and a third casting (12) of a SiC-based thixotropic material; the arrangement being such that said at least one ceramic insert (8) is arranged on said third casting (12) of a thixotropic material so that it assumes a substantially triangular shape, said first casting (9) is arranged on said third casting (12) at an exterior area with respect to said at least a ceramic insert (8), said second casting (10) of silica-alumina material having a high content of ZrO2 is arranged on said third casting (12) of a thixotropic material substantially at a central portion of the plate (5) defined by said at least one ceramic insert (8), said third casting (12) entirely covers said first and second castings (9, 10) on their back sides, and said plurality of joints (11) of ceramic fibres for the thermal expansion is arranged at contacting surfaces between said at least one ceramic insert (8) and at least one of said first, second and third casting (9, 10, 12).
