Refractory wall for protecting e.g. furnace's tubular space grid, has tiles mounted without binder, where peripheral faces of tiles are covered by visco-elastic material layer supplementing baffle formed by engagement of tabs in rabbet

摘要

The wall has a fixation unit formed of nuts (12) and a thrust washer (13), associated to a shock absorber body (14) that deforms to absorb dimensional variations to dilatations. The unit is protected from heat radiation by a cover (18) of heat insulation material. Each tile is mounted without binder and with transversal and peripheral clearances to allow freedom of movement in orthogonal directions. Peripheral faces of each tile coming in opposite to faces of juxtaposed tiles are covered by a visco-elastic material layer supplementing a baffle formed by engagement of tabs in rabbet.
