Method of lining a furnace with roll-type insulation

A method of lining an interior surface of a furnace with roll-type ceramic fiber insulation, said method comprising:

• (a) fixedly attaching a plurality of hook means to said interior surface of said furnace;
• (b) folding back portions of said roll-type ceramic fiber insulation on themselves to create transverse folds in said roll-type ceramic fiber insulation;
• (c) pressing said transverse folds onto said hook means to fixedly attach said roll-type ceramic fiber insulation to said hook means and to said interior surface of said furnace;
• (d) overlapping the side edges of adjacent transverse folds;
• (e) rolling portions of said roll-type ceramic fiber insulation into elongated rolls;
• (f) tying lengths of string about said elongated rolls;
• (g) gluing said elongated rolls to every substantially 90.degree. bend formed by said interior surface of said furnace;
• (h) abutting said transverse folds of said roll-type ceramic insulation and said elongated rolls;
• and
• (i) gluing the abutting edges of said elongated rolls and said transverse folds together.

A method of lining an interior surface of a furnace with a plurality of elongated lengths of insulation, said method comprising:

• (a) fixedly attaching a plurality of hook means to said interior surface of said furnace;
• (b) folding back portions of a first elongated length of insulation on themselves to create folds;
• (c) pressing said folds of said first elongated length of insulation onto a plurality of said hook means to fixedly attach said first elongated length of insulation to said hook means and to said interior surface of said furnace so as to line a first portion of said interior surface of said furnace with said folds of insulation;
• (d) folding back portions of a second elongated length of insulation on themselves to create folds;
• and
• (e) pressing said folds of said second elongated length of insulation onto a plurality of said hook means with one side edge of said folds of said second elongated length of insulation overlapping the adjacent side edge of said folds of said first elongated length of insulation to fixedly attach said second elongated length of insulation to said hook means and to said interior surface of said furnace so as to line a second portion of said interior surface of said furnace with said folds of insulation.

A method of lining an interior surface of a furnace with a plurality of elongated lengths of insulation, said method comprising:

• (a) fixedly attaching a plurality of hook means to said interior surface of said furnace;
• (b) folding back portions of a first elongated length of insulation on themselves to create folds;
• (c) pressing said folds of said first elongated length of insulation onto a plurality of said hook means to fixedly attach said first elongated length of insulation to said hook means and to said interior surface of said furnace so as to line a first portion of said interior surface of said furnace with said folds of insulation;
• (d) folding back portions of a second elongated length of insulation on themselves to create folds;
• and
• (e) pressing said folds of said second elongated length of insulation onto a plurality of said hook means with one top edge of said second elongated length of insulation overlapping the adjacent bottom edge of said first elongated length of insulation to fixedly attach said second elongated length of insulation to said hook means and to said interior surface of said furnace so as to line a second portion of said interior surface of said furnace with said folds of insulation.

A method of lining an interior surface of a furnace with roll-type insulation including first and second layers, said method comprising:

• (a) fixedly attaching a plurality of hook means to said interior surface of said furnace;
• (b) folding back portions of said roll-type insulation on themselves to create folds;
• (c) offsetting the ends of said first and second layers of said roll-type insulation one to the other;
• and
• (d) pressing said folds of said roll-type insulation onto said hook means to fixedly attach said roll-type insulation to said hook means and to said interior surface of said furnace so as to line said interior surface of said furnace with said folds of roll-type insulation.

A method of lining an interior surface of a furnace with a plurality of elongated lengths of insulation having first and second layers of different grades, said method comprising:

• (a) fixedly attaching a plurality of hook means to said interior surface of said furnace;
• (b) folding back portions of a first elongated length of insulation on themselves to create folds;
• (c) offsetting the ends of said first and second layers of said first elongated length of insulation one to the other;
• (d) pressing said folds of said first elongated length of insulation onto a plurality of said hook means to fixedly attach said first elongated length of insulation to said hook means and to said interior surface of said furnace so as to line a first portion of said interior surface of said furnace with said folds of insulation;
• (e) folding back portions of a second elongated length of insulation on themselves to create folds;
• (f) pressing said folds of said second elongated length of insulation onto a plurality of said hook means with one side edge of said folds of said second elongated length of insulation overlapping the adjacent side edge of said folds of said first elongated length of insulation to fixedly attach said second elongated length of insulation to said hook means and to said interior surface of said furnace so as to line a second portion of said interior surface of said furnace with said folds of insulation;
• (g) folding back portions of a third elongated length of insulation on themselves to create folds;
• (h) offsetting the ends of said first and second layers of said third elongated length of insulation one to the other;
• and
• (i) pressing said folds of said third elongated length of insulation onto a plurality of said hook means with the offset ends of said first and second layers of said first and third elongated lengths of insulation forming a splice with one another to fixedly attach said second elongated length of insulation to said hook means and to said interior surfaces of said furnace so as to line a third portion of said interior surface of said furnace with said folds of insulation.
