ABSTRACT:
A refractory sheathing (1) of incombustible, compressed, flat insulating bodies (8) made of mineral or ceramic fiber for thermally insulating pipes (10) in preheating furnaces fired from below in the steel industry is described. The insulating bodies (8) have an inner and, if desired, also an outer arc-shaped profile, they enclose the pipes (10) to be insulated totally or almost totally in circumferential direction, and they are secured at the pipe in close mutual abutment by at least two retainers which engage the ends of a plurality of adjacent insulating bodies (8) forming a stack of insulating bodies. The risk of separating from the pipe during the constant vibrations of the same is reduced and the space requirement for installation at the building site as well as the cost of mounting involved are scaled down by the line-up of a plurality of insulating bodies (8) on a plurality of spaced apart rods (11) to form a highly compressed insulating body stack. Between the retainers of the rods (11) acting at the ends, a plurality of compression holding clamps (16) are secured at mutual spacings. The tips (14) of the rods (11) may project beyond at least the one end face or butt face (23) of the insulating body stack which presents a prefabricated fibrous shaped section (2) and may be received in the end face or butt face (23) facing the same or in the retainer of the adjacent shaped section (2).
