1 Claim.
The present invention relates to new and useful improvements in furnace doors for use with open hearth, steel mill furnaces and other heating ovens and furnaces generally, and more particularly to flat-faced doors raised and lowered by chains to open and close the furnace openmg.
An important object of the invention is to provide a lining or filling of refractory material placed in the recessed rear face of the door in a poured state and reinforcing the lining or filler with steel rods embedded therein and constructed to take up shrinkage, expansion and contraction of the filler to forestall spalling and cracking of the filler and to prevent warping of the door.
A further object is to provide means for anchoring the reinforcing rods to the door in a manner to facilitate removal and relining of the door.
A still further object is to provide a device of this character of simple and practical construction, which is strong and durable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a front elevational view of the door;
Figure 2 is a rear elevational view with parts broken away and shown in section;
Figure 3 is a vertical sectional view taken on a line 33 of Figure 1;
Figure 4 is a horizontal sectional view taken on a line 44 of Figure 1;
Figure 5 is a rear perspective view of the door with the lining or filler removed; and
Figure 6 is a perspective view of the united reinforcing rods.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 4 designates the furnace door generally and which is constructed of a metal plate 5 welded or otherwise suitably secured to the rear side of an angle iron frame 6 and with the rearwardly projecting flanges 1 at its edges forming a recess 8 at the rear face of the plate. Reinforcing strips 9 of triangular shape in cross section are bolted or welded in the recess 8 at the angle of the flanges 1 and plate 6.
The recess 8 at the rear of the door is filled with a suitable refractory material 18 in a plastic state poured over the reinforcing rods [5 and [6 to embed the rods in the filler to form a lining at the rear face of the door.
The upper edge of the door is provided with the usual hoisting chain l9.
The reinforcing rods [5 and It tends to prevent cracking of the refractory filler or lining and the reinforcing strips 9 form a bevelled edge 20 at the inside of the filler to take up shrinkage, expansion and contraction thereof. Metal spuds 2| are welded to the rear surface of plate 5 to prevent warping, buckling or sagging of the filter.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described as preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.
Having described the invention, what is claimed as new is:
A furnace door comprising a metal plate, flanges projecting rearwardly at the edges of the plate to form a recess at the rear thereof, reinforcing bars at the front surface of the plate, a reticulated frame of intersecting rods positioned in the recess, threaded studs welded at inner ends thereof to the intersections of the rods and projecting from the frame through the plate and also throu h the bars with nuts on the outer ends thereof, a separate reinforcing strip of triangular shape in cross-section secured internally of the recess and attached therein at the junction of the flanges and plate, and a lining of poured refractory material in the recess covering the frame and reinforcing strip, said reinforcing strip extending around said recess with two sides thereof fitting flush against said plate and flange, respectively, and with the other side of said strip forming a bevel at the inner edge of the lining to compensate for shrinkage, expansion and contraction of the lining.
JAMES D. OCONNOR.
