INSULATING PIECE OF VARIOUS SHAPES MADE FROM A PILE OF LAYERS OF HIGH TEMPERATURE RESISTANT FIBRES, AND PROCESS FOR MAKING IT |
摘要 |
<p>An insulating structure is provided which includes a succession of superposed layers of fibers capable of withstanding high temperatures. A hot face of the structure comprises fibers capable of withstanding temperatures higher than the fibers of the cold face. The layers have an apparent density which varies from the hot face to the cold face. The structure contains fibers which have temperature-resistant properties which progressively decrease from the hot face to the cold face. The structure according to this invention can advantageously be applied to line ovens.</p> |
