Abstract
The coke oven refractory blocks each have 2 vertical partitions which are connected to each other in a tension-resistant manner by laterally distributed joining bodies which are arranged in a sharp corner, so that their distance varies along the entire wall length as a function of the dimension V. The profile bricks are retained by a bottom surface (22) and parallel upper surfaces (24). These surfaces (22, 24) are flat except for the grooves and projections used to shape the joint, characterized in that the block has a wall thickness that is not only planar (18) at the coke edge, but also planar (20) at the tensile edge. A land (14, 16) extends forwardly from the tensile edge (20), and the upper surface (24) and the lower surface (22) of the land (16) have at least one projection (26) and one groove (32) extending transversely of the length of the land (16). The projections and the grooves form an overlapping profile connection with one another and they are at a distance from the free end of the engagement region (16) which is greater than the dimension V, and the grooves (32) or the projections (26) extend in the engagement direction over a width which is greater than the dimension V.
Description
The present invention relates to a kind of coke oven shaped brick, this shaped brick respectively has two vertical partition walls, linker by lateral distribution forms the tension connection mutually, like this, and the formation one between them, and all put mutually and stand in the angle of wedge, their are through the distance of total brick wall length, with size V change, by the bottom surface with parallel with it above shaped brick is limited, the groove and jut that connects except being shaped, the shaped brick face is all flat.
Obtained by German Patent 2056119 or 233183 known coking furnaces, they are all made by less relatively shaped brick.For shaped brick can being arranged in a very sharp-pointed angle mutually and laterally is built into partition wall by linker, thus need numerous, if difform wall brick-every block wall brick is when carrying out appearance mutually and connect by groove and rib.When the coke oven pipe is installed new furnace lining, because respectively also this has just brought problem to shaped brick, and the very big workload of need spend, especially when repairing, totally unfavorable, because can not accurately judge, which piece shaped brick is to need to repair, the shaped brick of exhausted all size before also needing simultaneously to have, this causes inventory cost to increase again.
The object of the invention is to provide a kind of furnace lining shaped brick, uses this shaped brick just can make and builds the lining work that makes new furnace, and the task of particularly repairing coke furnace carbonization chamber becomes simple.Although still keep the moulding of shaped brick to connect, adopted the shaped brick of less kind of shape to reach the consumption that as far as possible reduces shaped brick as much as possible, promptly can reach the abutment wall that forms coke furnace carbonization chamber and finish shaped brick arrangement effect.
The present invention seeks to by realizing by the shaped brick of following conceptual design.That is: shaped brick has a partition wall thickness, one side what not only be in coke is a flat face, and the pulling force limit also is a flat face.From being subjected to stretch out a bonding land before pulling force face one side direction, the upper surface of bonding land and lower surface have a projection and a groove at least, the length direction of these protuberances or groove and bonding land is laterally distributed, make the shaped brick of mutual overlapping form that a kind of moulding connects and these grooves or projection have a distance apart from the free end of bonding land, this distance will be significantly greater than size V, and its groove or protuberance extend a width along the conjugant direction, and this width is greater than the V size.
Basic thought of the present invention is that the shaped brick of use both can generate a wall district that limits contact coke wall, and a bonding land is arranged again, and this zone can form a kind of horizontal connection of tension and each pulling force is longitudinally scatter.According to shaped brick of the present invention an engaging zones is arranged, this part is along its length drawout, so that connect the long web member of literary composition.If be built into short conjugant, then can amputate, the bonding land is shortened.Therefore,, except that special burner district brick, promptly can be made into the vertical area of coke furnace carbonization chamber, for example, promptly enough made brick structures with two different coke ovens with very a spot of shaped brick.
If the shaped brick conjugant is shortened by sawing, thereby make the conjugant of making than the longest linker (brick)) in short-term, then can cause the top limit of conjugant and groove and the jut on the following limit not to keep the distance that equates with the partition wall of opposite side, therefore, sawing will be carried out on the end in conjugant zone.In this zone or do not have jut and a groove, perhaps be exactly to leave them a segment distance is arranged, like this, the free end of the bonding land that forms after the groove in the fit district of short circuit or jut and the sawing can be kept enough distances all the time, thereby makes groove and the jut can be along conjugant direction transmission pulling force.Although the brick frame is shorter and shorter to another terminal from stove one end,, connect in order to reach moulding, it is wide abundant that its groove and jut are wanted.When last mud, perhaps the relative part of the groove of broad (this part do not need rabbet) is filled up by mud, dwindle wide jut before perhaps just before engaging, reaching mud, it can be matched with the conjugant that specifically prepares.In this way, can be applied to the block work of tearing open of each place easily, can be fit to the needs of various geometrical dimensions of laying bricks according to shaped brick of the present invention, thereby reduce the stock significantly.When building new furnace lining or repairing furnace lining, can prepare necessary use shaped brick earlier and use the local shaped brick that damages, and if not use this shaped brick of the present invention to be substituted in, then time-consuming, take a lot of work and play kitchen range again according to state of the art.
According to the present invention, the bottom surface of every brick bonding land and upper surface have a jut and a groove at least, and jut and groove can be rabbeted mutually when overlapping.If have only a groove, above for example this groove is positioned at, or have only a jut, for example it is to be positioned at the bottom surface, then these grooves and jut must be sufficiently wide, to allow to rabbet the conjugant length that there is arrival in the residence.If jut direction of engagement sidewards is narrow, then just require the groove on the respective direction that enough width must be arranged.If when beginning, choose jut than broad, then can excise or grind off projection, it is shortened become in groove in advance and can embed.
Also can select to have the shaped brick of a plurality of grooves and a plurality of juts, these grooves or jut are to distribute like this on its land lengths: make it have at least a jut can be embedded in the groove, unwanted jut to be ground off simultaneously, the total width of groove can be reduced according to the method.
The invention still further relates to the technology of building the system coke furnace carbonization chamber by shaped brick of the present invention.When making in this way, the bonding part of shaped brick is by sliding short, thereby can prepare the various conjugants that need length, and same, jut also has been shortened, and part is processed falls.
As outstanding advantage is that conjugant only prepares (not being the fragment of brick that adds a simple form by other) by shaped brick of the present invention bonding land.According to method of the present invention, construction coke furnace carbonization chamber seam is few.Therefore, seldom time-consuming on the one hand when building a wall, also can reduce the generation weak part on the other hand, these positions usually all by causing seam more.
If when selecting to have T type beam and being the T brick of different lengths on two, then as long as the limit portion boundary that just can make coke furnace carbonization chamber with two shaped bricks separates except anti-wall-burner end special shape brick.Because the T beam length difference of two bricks, can avoid intersecting the appearance of seam.
Because the conjugant zone length seam just can not occur intersecting so greater than half length of the longest conjugant of taking over yet in the conjugant zone.
Relevant other advantage of the present invention can be learnt that this narration is not limited to get a thorough understanding of example of the present invention by claim and following narration, and more relate to the detailed explanation to drawing, and these figure have:
The skeleton view of Fig. 1 coke furnace carbonization chamber wall, the wall of this coking chamber is made according to two kinds of different original-shapes by shaped brick.Fig. 2 is according to the vertical view of first shaped brick in Fig. 1 example, and this brick is the T brick.
The vertical view of second shaped brick in Fig. 3, Fig. 1 example, this brick are the T brick of main beam transverse.
Fig. 4 presses the vertical section of Fig. 1 example by the bonding land.
The sectional view of the similar Fig. 4 of Fig. 5 still, has two juts on face of shaped brick, and two grooves are arranged on the another side.
Fig. 6 still, has two protuberances on the face of shaped brick with respect to a kind of expression of Fig. 4, has only a groove on another side.
Fig. 7 is according to the another kind of representation of Fig. 4, still, has much than this wide projection on the face of shaped brick, and have only a groove on another side, still do not have projection at the dotted line that is drawn.
Coke furnace carbonization chamber according to Fig. 1 to 4 example is to be formed by two difform shaped brick systems of building.These two kinds of shaped bricks promptly among the figure 10 and 12, are all T type (being seen by top), and the crossbeam of shaped brick 10 is longer than 12 crossbeams.Two shaped bricks 10,12 have a bonding land 14,16 respectively.Can find out that from example the bonding land of shaped brick 10 is shorter than the length of half conjugant significantly.Because the length difference of T brick, and the length difference of bonding land 14,16, thereby avoid having occurred intersecting seam.Can clearly be seen that this characteristics from Fig. 1.
As shown in Figure 1, the T beam has just constituted partition wall, and T should have a thickness deeply mutually, and this thickness also just equals partition wall thickness.The fourth beam of shaped brick 10,12 has a side that contacts with coke respectively, and promptly the plane 18, and a pulling force limit, and promptly the plane 20.The brick body bonding land 14 and 16 that the latter stretches out by the centre separates.
In addition, shaped brick 10,12 respectively has smooth bottom surface 22 and the end face 24 that parallels of face therewith, and these two faces are perpendicular with the side of being mentioned 18,20.Surface 22,24 is all disconnected by groove and jut, and the back will be described this.
Be positioned at 22 places, bottom surface in T beam zone projection 25 is arranged respectively, this partial cross section is semicircular in shape basically, and these juts 25 all are positioned on the end face of T beam, on the partition wall of Fig. 1 left side, be in the face of viewer's projection promptly, and on the partition wall of the right side of Fig. 1 be in the face of the viewer recessed.In addition, being positioned at 16 places, bonding land in the bottom surface of shaped brick 12 has a projection 26, and this projection is that direction of engagement distributes sidewards, and this is to the present invention very important (back also will be described in detail).In addition, be positioned on the limit, bottom surface of shaped brick 10 of T Liang Qu and respectively stretch out projection 28, it is mutual square crossing with the projection of having mentioned 25 and distributes, and keeps a distance with end face, and this distance is equivalent to 1/4 of beam and grows.Be provided with groove 30 on shape face and the corresponding same area of projection on the shaped brick of long T beam.When overlapping for two, projection 28 just is embedded among this groove 30, and this as shown in Figure 1.On the upper surface 24 and each free end face of shaped brick 10,12, also have groove 31, they also are semi-circular sections, are used for engaging with projection 25 noted earlier.In addition, on the upper surface 24 of the shaped brick 0 of long T beam, be provided with groove 32, it is more relatively large that this groove is positioned on the direction of engagement its width, and it is to be used for being halved together with projection 26, also will illustrate respectively this two groove.
The total length of two brick bonding lands 14,16 is to constitute like this: when two butt end faces are close to mutually, add mud again and stitch the longest linker length that has just constituted between the partition wall.If build the short linker of system, perhaps the bonding land 14 of coke oven 10 is shortened.Or brick tagma 16 shortenings of shaped brick 12.In the example of Fig. 3, be that brick body interior 16 is shortened, this can be showed by dotted line 34.
As shown in Figure 1, if if during the range difference V=85mm in whole length range between two partition walls, then the longest linker is this size approximately just, still, deduct several mm and slightly long than the shortest linker.In order to build the shortest brick body of system, then must shortening bonding land 16 in the given example, above corresponding size be 80mm.Same method of calculation are applicable to that also the width of groove 32 calculates (all directions connect).The size V that the total width of groove reduced above being (being 80mm in the example), the width of processing projection 26 and two mud seams please the typical total width of groove be 120mm just like this.
In given example, 16 free end has a distance to groove 32 apart from the bonding land, and this distance should be greater than size V.For safety, when cut-out meets platform district 16, do not run into groove 32, would rather make between the free end of groove and bonding land 16 and leave enough materials, so that projection 26 can embed and keep moulding to connect.
Fig. 4 represents to be used for the joint situation between two shaped bricks 12 of short as far as possible conjugant, and long and short dash line represents to be used for the mated condition of the shaped brick 12 of long as far as possible conjugant.As shown in the figure, projection 26 has a distance apart from the left side terminal of groove 32, and this spacing has only the width of a mud seam, and same, in order to engage brick body as much as possible, projection 26 must be pressed close to the right-hand member of groove 32, so also will leave the position of a mud seam.Therefore, in order to hold all sticky objects in groove, projection 26 should be in the mid-way by two kinds of end bit representations.
Also can shorten bonding land 16, last, can also all shorten bonding land 14,16 simultaneously, so that the system of building is shorter than the conjugant of long brick, still, expense is big like this.
The represented purpose of Fig. 5 example is, avoids producing the product of the groove of relative broad.Two identical shaped projections 26 are made in close projection 26 positions, and two corresponding therewith cooperations of groove are arranged.Situation when Fig. 5 also expresses two shaped bricks 12 and is used for a conjugant, its length just in time is in the centre of long and the shortest conjugant.As shown in the figure, in this case, left side projection 26 separates by the right-hand member of mud seam with left groove 32, and is corresponding therewith, and the right projection 26 also is to separate by the left end of mud seam with the right groove 32.As shown in Figure 5,, then to grind off the right groove 32,, then will remove left side projection for the short conjugant of total length for long conjugant.
Two projections 26 are also arranged in Fig. 6 example, but two projections only are used to cooperate a groove, this is to need for the conjugant that engages moderate-length.If the system of building is shorter than illustrated conjugant, then should remove left side projection 26, if it is longer than diagram to build the system conjugant, then correspondingly through removing the projection on the right.
At last, Fig. 7 represents a kind of projection 26 situations of extra wide, in the time of matching with desirable conjugant length, then will cut.What represent in the example that provides is the shortest conjugant, and the right long and short dash line represents that the partial zones of projection 26 can remove.From sciagraph, can find out, in the time will cooperating the longest conjugant, then will remove the left side partial zones of projection.If when cooperating the conjugant of moderate-length, then the projection 26 on the left side and the right all will be removed.
Shaped brick 10,12 is made by fusion silicate, forms by the hydraulic pressure pressing, and they are neutral, are not actually thermal expansion to occur.
