Abstract (en)
This invention relates to a covering block (1) for furnaces of the suspended roof type, characterised in that it comprises a plurality of superposed layers having different refractory and insulating properties. In particular, the block comprises a first layer (3a) having high refractory properties and at least a second layer (4a,4b), superposed to the first one, having high insulating properties. The desired level of refractory and insulation of the furnace is ensured in any case by a plurality of blocks of easy manufacturing and contained cost, so as to reduce the amount of the investments that are to be provided for the manufacturing of such roof. <IMAGE>
