<p>The shield has a fibrous refractory sheet (13, 33), disposed between two metallic lattices (15, 15 min , 35, 35 min ), the lattices connected by fastening means to retain the sheet (13, 33) to form a panel having a bottom wall (3, 23), upstanding side walls (5) and a flange (11, 31) extending outwardly from the side walls (5). In one embodiment the metallic lattices (15, 15 min ) substantially cover the fibrous refractory sheet (13), while in another embodiment cross strips of metallic lattices (35, 35 min ) are used with a combustible supporting frame (41) provided about the periphery of the fibrous refractory sheet (33) to support the same.</p> |
