Abstract
A device for mounting panels of fibrous refractory material against the inner surface of the wall of an industrial furnace, comprising a plug of refractory material in the form of a bolt with a square head and a non-threaded cylindrical shank provided with a plurality of circular ribs arranged in planes perpendicular to the axis of the plug, the panels to be attached thereby having spaced-apart apertures of dimensions intermediate those of the head and of the ribs on the shank, and the wall of the furnace having corresponding cavities filled with a sealing material and for receiving the shank of the plug.
Claims5
A device for mounting panels of fibrous refractory material of a predetermined thickness against a wall of an industrial furnace, the device comprising:
- a plug of refractory material having the form of a bolt with a square head and a non-threaded cylindrical shank provided with a plurality of circular ribs, said plug having an axis arranged in planes perpendicular to the axis of said plug, the panels to be attached thereby having spaced-apart apertures of dimensions intermediate those of said head and of said ribs on the shank, and the wall of the furnace having corresponding cavities filled with a sealing material and for receiving said shank of the plug;
- and
- two washers of combustible material, which are to be burned in the furnace and thereby eliminated at the first heating, one of said washers being adapted to be arranged between said head of the plug and the refractory panel to be mounted by said plug, the other of said washers having a height substantially equal to the thickness of the panel, and being adapted to line the apertures in the panel into which said plug is introduced and consequently surround a portion of said shank of the plug adjacent said head.
