Novel shapes of refractory jamb bricks are disclosed which are readily removable ant replaceable without tearing down and rebuilding the novel jamb structure of a heating wall of a coke oven battery.
Description
~0383Z3 This inventlon relates to coke oven batterles and, more particularly, to a novel ~amb structure at the ends of the heating walls of such batteries.
In a coke oven battery the end ~amb brick arrangement, which lncludes the bricks at the extreme ends of the coking chambers and the bricks at the outer ends of the heating wall ent ~lues, are the portions o the heating wall that are sub~ect to.the most wear and tear, and have to be most often replaced.
The end ~amb-bricks are exposed to.the heat of.the oven . during coking and to ambient temperature and weather conditions each time .the coking.chamber doors are removed for pushlng coke. Sooner or later these end ~amb bricks spall under.such conditions, and crack and then must :.
be replaced.
To be satlsfactory, an end ~amb brick:must admit of easy ~emoval and.replacement without disturblng the other ~amb bricks which are . under compressive stre~s by.the.buckstays. :~urther,.the ~smb brick should be readily removable and replaceable without exposing any of the heating flues to ambient conditions, particularly the end.flues.
Not all design of ~amb bricks that are said to be easily and . 20 readily removable and replaceable, have proven to be satisfactory in service.
It has been found that in some instances, the door ~amb casting structure .must be removed before the ~amb bricks can be removed and replaced. Such a situation, those skilled in the art will recognlze, is not satisfactory.
.~urthermore, in some such lnstances, the mortar in the horizontal ~oints .
between bricks ls pushed out in service and the maintenance of these ~oints has been both costly and time consuming. Such work must be carried on .
. continually. .
Those skilled in the art, from the following description, wlll recognize that each lndividual ~amb brick of the present invention can be removed and replaced readily and quickly, without involving the door ~amb t castlng. No alterations to ad~acent bricks are required ln order to accomplish this purpose. ~ ¦

~0383Z3 For a further understanding of the invention and for features and advantages thereof, reference may be made to the following description and the drawing which illustrates preferred embodiments of refractory shapes in accordance with the invention.
In the drawing:
Figure l is a vertical face view of the jamb structure of a heating wall located at one end of a coke oven battery;
Figure 2 is a vertical face view of the jamb structure of a heating wall of such coke oven battery;
Figure 3 is a view along line III - III of Figure l;
..
Figure 4 is a view along line IV - IV of Figure 2;
Figures 5-9 are refractory shapes in accordance with my invention that are used in the jamb structure of Figures l and 2; and Figures lO - 12 are other refractory shapes in accordance with my invention that are used in the jamb structure of Figures 1 and 2, Referring to the drawings, Figure 1 illustrates the face view of the end wall jamb structure 11 of a coke oven battery 13, and Figure 2 illustrates the face view of the jamb structure 15 of a typical intermediary heating wall 17.
The jamb structure 11 includes a plurality of pairs of courses l9, 20 of interdigitating refractory brick shapes, and there are, generally, three complete, whole brick shapes 23, 25, 27, and a portion of a fourth brick shape 29 in each horizontal course, as shown in Figure 3.
The whole brick shapes 23, 25 are of substantially conventional form, but the refractory brick shapes 27, 29 have novel forms as described herein and as shown in the drawings.
The refractory brick shape 27, which interdigitates with two adjacent refractory bricks 29, 29a, has the form shown in Figure 10. The . refractory shape 27 is characterized in a top or plane view (corresponding to the view shown in Figure 3) as having an L-form with a large radius sweep-portion 31 that is designed to fit around a conventional door jamb 33.
~ i ~038323 The top surface of the shape 27 has an upwardly inclined portion 35 that co-operates with a radius portion 37 of brick shape 29, shown in Figure 8. The top surface of shape 27 also has a groove 39, which is shaped to coact with a tongue 41 on the bottom surface of refractory shape 43 that is shown in Figure 14. The refractory shape 27 also has a tongue 45 on a vertical sur-face 47, and a tongue 49 on the bottom surface 51, which tongues 45, 49 cooperate with groove 53 in refractory shape 25 and another groove in 43a, the shape 43a being locaeed in the next lower adjacent horizontal course.
It will be noted from Figure 1 that the shape 27 coacts with the lower portion of shape 29 and with the upper portion of shape 29a, which is substantially identical to shape 29. Refractory shape 29 (also 29a) is shown in Figure 6 and it is characteri~ed as having a generally rectangular body portion 57 from the top portion of which an outwardly and downwardly extending portion 59 projects. The outwardly and downwardly extending por-tion 59, having parallel top and bottom sloping surfaces 60, 60a, merges with the vertical body portion in a radius 61 that cooperates with a rounded portion 63 of the refractory shape 27, shown in Figure 10.
The top surface 65 of shape 29 includes a surface 60 of the portion 59. Such sloping top surface 65 cooperates with a corresponding sloping surface of refractory shape 29a in the hori~ontal course of bricks immediately below, as shown in Figure 1.
The refractory shape 29 has a sloping bottom surface 69 that is generally parallel to the top surface 65 and to the sloping surface 60a.
Thus, there are three parallel sloping planar surfaces 60a, 65, 69, of shape 29 and each one of these surfaces cooperates with a sloping planar surface of adjacent jamb bricks.
Figure 8 illustrates a refractory brick 28 (and also an identical brick 28a) that is substantially similar to the refractory brick 29 except that the brick 28 (and 28a) is somewhat more rectangular in shape, as seen in the top view.
The refractory bricks 28 (and 28a) are installed in the top ~ _ 3 _ , . . .
.
portion of the end wall jamb structure 11 where shown in Figures 1 and 2.
The lowermost horizontal course of refractory shapes (Figure 1) comprises three whole refractory brlcks 71, 73, 75 and the lower portion of refractory brick 77. The refractory bricks 71, 73, 75 are sub-stantially like refractory bricks 23, 25, 27 except that bricks 71, 73, 75 are slightly taller - 3a -C
103~323 and they have no bottom tongues, like the tongue 49 of brick 27. The bricks 71, 73 and partlcularly brick 75, have planar, flat bottoms that rest upon the flat oven floor 79.
The refractor~ brlck 77, shown in Pigure 5, is substantially like refractory brick 29 (Figure 6) except that brick 77 has a slightly longer lower portion 81, and it has a flat bottom surface.83 in contact with the flat oven floor 79. The other portions of refractory brick 77 (Figure 5) are.substantially like the same portions of refractory brick 29 shown in Figure 6 and described herein.
. Refractory brick.21.is shown in detail in Figure 7 and it comprises a.substantially vertical portion 85, and a downwardly and.out~ardly extending side portion 87 that merges with.the vertical portion in a radius 89. The top.surface portions 91 of.the vertical and side portions 85, 87 from a single planar.surface that slopes do w ard in-the same manner as .surface 65 of refractory shape 29 (Figure 6). .The bottom:surface portion 93 of.the vertical portion 85 slopes in a generally parallel relation to the top.surface 91. The rlght~hand vertical:surface 95 of vertical portion 85 (as viewed in Figure 7, front vie~) is disposed as~ew to.the opposite vertical :surface portion 97 of the vertical portion 85, as.shown in Figure i. Like~
wise, one surface portion 97 of.the side portion 87.is.askew with respect to .the opposite side portion 99, as.shown in Figure-7. Refractory.shape.21, like refractory shape 29, has three parallel plane:surfaces 91,.93 and IQl;
.surface 101 being the bottom.surface of portion 87.
Refractory shape 43 is shown in detail in Figure 12 and, it will be noticed, it is simllar to shape 27 but for the inclined portion 35 of shape 27. Shape 43 is generally rectangular in plan ~iew with the lower left corner portion 103 formed in an ~rcuate manner as shown. The top.surface 105 . has an elongate groove 107 therein, where shown. Directl~ beneath such groove 107 there is a tongue portion 41 which, as mentioned herein before, coacts with the groove 39 in refractor~ shape 27. ~ ~ertically arranged . tongue 109 is disposed on a vertlcal s~de of shape 43, where shown, and this I
C tongue coacts with a vertical groovei~t~ ~n adJacent reractory.shape 113 (Figure 4).
Referring to ~lgure 4, refractory shape 115 is substantially the same as refractory 43 except to the opposite hand.
Referring to Figure 2, refractory shapes~ ,'.ll9 and 121 are respectively like shapes.43~ 27 and 29 respectively, but to the opposite hant.
. Figure 9 illustrates a'small refractory shape 123 that is locatet at the top of.the ~amb structure (Figure l). In ~igure 2j refractory ' shape 125 is ~imilar to.shape 123,.but to.the opposite hand. .Sbape 123, as .sho~n, is generally rectangular,~but has a sloping bottom:surface 127 that . cooperates with sloping surface 65 o~.shape 29 in.the next lower course of bricks.
~ igure.11 illustrate6 reractory.shape.129.which.is similar to.shape 27. Shape 129, however, has a flat planar top l31 that coacts with .the oven roo brickwor~.133. .The bottom:surace 0.6hape I31.is planar and patallel to the top.surface 131 in one portion.135 ant iB slopet upwardly in another portion.137 80 as to cooperate parallely to:surface 35 of.shape : 27 immediately therebelow in.the next lower course of Jamb bricks.
' . 20 .The bottom.surface portion.135' is provided with a tongue-139 .that coacts with groove 39 of.shape 27. A vertical tongue 141 is provided on surface 143, which tongue coacts with-groove 53 in ~efractory brick.shape :. : 25.
Thus,.substantially all of the novel refractory brick shapes of.the present inventlon have been described and are.shown.
~rom the oregoing description of the several'embodiments.o .the invention, those skilled in the art should recogn~zé ~any'important features and advantages o it,'among which the ollowing are particularly significant:
That each refractor~ shape comprising the ~mb bricks can be indivldually removed and replaced on both the pusher and the coke sides without disturblng the door ~amb castings, without making any fleld altera-tions, and without damaging any ad~acent bricks in the end wall structure;
That the sloping.surfaces of the novel ~amb shapes increases the stability o the mortar in the ~oints between ad~acent bricks; and That the center o gravity o the novel ~amb.shapes havlng the outwardly and downwardly pro~ecting portion i8 below and toward such pro~ecting section. Wherefore,.such ~amb shapes tend to "lean" towards the flue wall and this tends to keep all of.the vertical ~oints tight.
. Although the inventlon has been described herein with a . certain degree of particularity it is understood that.the present disclosure has been made only as an example and.that.the:scope:o.the invention is defined by what is hereinafter claimed.
