Abstract
An L-shaped insulating module for use on outside and inside corners as well as on door jambs in a high temperature furnace. A module of refractory fibers is constructed of one blanket folded in accordance with a particular sequence to produce a first region with a first number of layers and a second region with a second lesser number of layers which is generally half as many as the first number. One-half of each of the second layers is removed to produce an L-shaped component. A second component member is interleaved with the layers of the second region to produce an L-shaped module of uniform thickness. Mounting hardware is attached to two faces of the module for attachment to their respective wall faces. The attachment is such that it retains the two components in assembled condition.
Claims10
An article for insulating portions of two walls in the region of a corner or similar discontinuity in a furnace, said article comprising an L-shaped module with first and second multi-layered arm portions including a first generally L-shaped member with first and second multi-layered leg portions, said first leg portion corresponding generally to said first arm portion, a second member interleaved in serpentine fashion with said second leg portion to form said second arm portion, means to attach said first and second arm portions to their respective furnace walls.
A method of making a modular article to insulate portions of two walls in the region of a corner or similar discontinuity in a furnace comprising the steps of:
- (a) folding a first insulative blanket in a particular repetitive sequence to define an element from which a first component will be formed, said element having a first region with `x` number of layers and a composite thickness `t.sub.1 ` and a second region with `y` number of layers and a composite thickness `t.sub.2 ` with `x`>`y` and `t.sub.1 `>`t.sub.2 `;
- (b) removing a portion of the layers in said second region of said element to form a generally L-shaped first component;
- (c) interleaving a second component with the layers of said second region, the resulting layers of said second component numbering `z` and having a thickness `t.sub.3 `;
- and
- (d) securing means of attachment to one side of each region for securement to said respective furnace wall;
- such that the resulting module has a first multi-layered region with a thickness `t.sub.1 ` and a second multi-layered region with a composite thickness `t.sub.2 `+`t.sub.3 `.
