<p>The inner walls of industrial furnaces are lined with a plurality of insulating blocks, each block comprising an insulating mat folded in corrugated manner and possibly stitched in this shape, the insulating mats being made of highly heat-resistant material, especially ceramic fibrous material. Carrying elements arranged on the outside of the corrugations, the carrying elements being equipped on the outside of the insulating blocks with fixing means to allow individual insulating block to be fixed to the furnace wall. A base plate is provided on the outside of each insulating block, the base plate having at least two webs extending outwards and located on opposite sides of The base plate, such as to allow adjacent insulating blocks to be interconnected by means of fixing bolts passing through the webs. The base plate serves as a connecting element between the carrying elements for the folded insulating mat and the fixing means. The fixing means comprise hooks attached to the base plate in a manner as to permit their rotation. The hooks are capable of suspension from holding bars provided in the furnace wall. A retainer is inserted between the holding means and the web of an adjacent base plate at the location of each hook to prevent accidental detachment of the hooks.</p> |
