<p>A heat shield arrangement for hot material (M) in strip or bar form comprises insulating panels (2, 4) that have a thin heat-resistant hot face (73) confronting the material (M) and backed by a heat-insulating core (74, 75). To protect the panels (2, 4) against damage from distorted material (M) or material lifting from its normal path, a contact member (6) is disposed over the material (M) and if it is struck by the material (M), the member (6) actuating means (46) to raise the panels (2, 4). The panels (2, 4) are displaceable relative to each other in order to vary their shielding effect over the lateral extent of strip-form material (M). In an arrangement particularly for bar-form material, the panels form a tubular conduit enclosing the material on all sides.</p> |
