Refractory insulation mounting system and insulated structures

An insulated furnace wall for a high temperature furnace, comprising:

• (a) an external wall member;
• (b) a layer of refractory insulation positioned on an interior side of the external wall member, the insulation layer being formed from fibrous refractory material;
• (c) frame means including compression surfaces for compressing the stack of planks over a substantial area and for retaining the stack of planks in a compressed condition;
• (d) attaching means for connecting the stack of planks in relation to the wall member, including ruggedly surfaced metal sheets disposed substantially coextensive with said planks embedded within the layer of fibrous refractory material, and connection means for connecting the ruggedly surfaced metal sheets to the wall member;
• and
• (e) the layer of refractory insulation being formed in situ about the connection means, whereby the layer is an integral structure that is reinforced by the embedded connection means.

An insulated furnace wall for a high temperature furnace, comprising:

• (a) an external wall member provided with spaced elongate slots extending in a first direction;
• (b) a body of fibrous refractory insulation on an interior side of the external wall member, the body being formed from a plurality of layers of fibrous material that overlie each other to form a stack that has opposed faces;
• (c) sheets of expanded metal embedded within the body of fibrous refractory material, said sheets being substantially coextensive in area with said layers;
• (d) anchoring devices for connecting the sheets of expanded metal with the external wall member, including rods each extending through one of the slots and provided at one end with a hook for engaging an opening in one of the expanded metal sheets, and at the other end with an adjustable abutment;
• and,
• (e) opposed flanges defining compression surfaces on the external wall member for engaging substantial areas of the opposed faces of the stack, for compressing the stack to distribute compressive forces throughout the layers of the stack, and for maintaining the stack of interleaved planks and sheets in a compressed condition.

An insulated furnace wall for a high temperature furnace, comprising:

• (a) an external wall member provided with spaced elongate slots extending in a first direction;
• (b) a layer of fibours refractory insulation on an interior side of the external wall member;
• (c) sheets of expanded metal embedded within the layer of fibrous refractory material and substantially coextensive with said refractory layer;
• (d) anchoring devices for connecting the sheets of expanded metal with the external wall member, including rods each extending through one of the slots and provided at one end with a hook for engaging an opening in one of the expanded metal sheets, and at the other end with an adjustable abutment;
• (e) opposed flanges on the external wall member defining compression surfaces for engaging substantial areas of opposed faces of the fibrous refractory insulation and the sheets or expanded metal for maintaining the same in compressed condition;
• and,
• (f) the layer of refractory insulation being formed in situ about the connection means whereby the layer is an integral structure that is reinforced by the embedded connection means.

An insulated furnace wall for a high temperature furnace, comprising:

• (a) an external wall member having portions thereof defining opposed compression surfaces;
• (b) a sequence of elongate three-walled, U-shaped cages mounted on the inner surface of the external wall member with their open sides directed away from the external wall member, the cages being formed of ruggedly surfaced metal sheets and designed for cooperation with planks of fibrous refractory material of predetermined thickness, the openings of the cages and the space inbetween cages being substantially equal and having a dimension less than the normal thickness of two of the planks;
• (c) a pair of elongate superimposed planks of fibrous refractory material in each cage;
• (d) a pair of superimposed planks between each adjacent pair of cages, all of the planks and cages being received between said compression surfaces and retained in compressed condition thereby;
• and,
• (e) each of the metal sheet cages being substantially identical in length to the length of the planks of fibrous material contained therein whereby said cages and said planks are substantially coextensive in area.
