Abstract

L'invention concerne une structure support (32) pour supporter des briques d'empilage (5) d'un régénérateur de haut-fourneau, la structure comprenant des briques à pente (7) destinées à supporter les briques d'empilage (5) et des briques support (6) pour supporter les briques à pente (7). Les briques à pente (7) présentent un corps (70) et des passages inclinés (75) qui communiquent avec les trous traversants (54) des briques d'empilage (5) et qui s'ouvrent sur la surface latérale du corps (70). Les briques à pente (7) sont agencées le long de surfaces inclinées imaginaires qui séparent l'intérieur du régénérateur de haut-fourneau en une section supérieure et une section inférieure. Des passages horizontaux (35) qui communiquent avec les passages inclinés (75) sont formés entre les briques à pente (7) et les briques support (6).
