发明名称 Plates with ceramic layers for apparatuses for the continuous casting of flat thin products and process for the manufacture thereof
摘要 The present invention provides an improvement to the plates for the side containing in apparatuses for the continuous casting of thin flat products, said plates comprising: at least one insert (8) of a ceramic material; a plurality of joints (11) for the thermal expansion, the joints being constituted of a ceramic fibers material; a first casting (9) of a silica-alumina material containing ceramic fibers; 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 a ceramic insert is arranged on said third casting (12) of a thixotropic material so that it assumes a substantially triangular shape, said first silica-alumina casting (9) based on a ceramic fibers material is arranged on said third casting (12) at the exterior area with respect to said at least a ceramic insert, said second casting (10) of silica-alumina material having a high contents of ZrO2 is arranged on said third casting (12) of a thixotropic material substantially at the central portion of the plate defined by said at least a ceramic insert (8), and said plurality of joints (11) in ceramic fibers for the thermal expansion is arranged at the contacting surfaces between said at least a ceramic insert (8) and at least one of said first (9), second (10) and third casting (12).
